It is one of Teledyne Isco’s 3700 Series of portable and refrigerated samplers.
3700R/3740 Refrigerated Sampler Section 1 Introduction arm to the next bottle. A desiccator is installed in the control box to prevent moisture damage to the electronics, pump, and distributor systems. 1.1.2 3740 Refrigerator If you want to convert a presently owned 3700 Portable Sampler into a refrigerated unit, or to have both portable and refrigerated options with the same controller, the 3740 Sampler Refrigerator is available.
3700R/3740 Refrigerated Sampler Section 1 Introduction 1.2.1 Flexible Sampling Intervals The 3700R is designed to collect up to 24 separate sequential (discrete) samples and is fully programmable for true composite sampling. Both sequential and composite samples may be collected at user-definable time intervals (time pacing) or at equal flow volume intervals using flow pulse inputs from an external flow meter (flow pacing). The flow interval is set from 1 to 9999 flow pulses.
3700R/3740 Refrigerated Sampler Section 1 Introduction where you need a series of identical sets of samples. Multiple bottle compositing can be used when you need to acquire a series of larger volume composite samples by taking a number of smaller samples and distributing them over several bottles. In the extended programming mode, you can switch multiplexed bottles or bottle sets after a programmed number of samples have been deposited or after a programmed period of time has elapsed.
3700R/3740 Refrigerated Sampler Section 1 Introduction current date. The start time delay is the period between the time you press the start sampling key and the time the routine actually starts. It is adjustable from 0 (zero) to 9999 minutes. Other features are available. Program storage allows you to store up to three separate programs, eliminating the need to reprogram the sampler for recurrent sampling routines. A program lock prevents unauthorized program alterations.
3700R/3740 Refrigerated Sampler Section 1 Introduction matic rinsing of the suction line when concerns of cross contamination arise. A programmable setting for sampling retries is available. If the suction line becomes clogged and no liquid is detected in the line, the sampler can be programmed to repeat a purge cycle – up to three times – to clear the clogged line. 1.4.2 Pump Tubing and Suction Lines The pump tubing is Silastic™ medical grade silicon rubber.

A control condition is simply the set of parameters defining the conditions in which a flow meter will enable the sampler. For example, a flow meter can be programmed with a control condition which is satisfied when the flow meter detects 1/4 inch of rainfall in 15 minutes.
3700R/3740 Refrigerated Sampler Section 1 Introduction 1.7.4 Liquid Level Actuator 1.8 Technical Specifications, Controls, and Connectors The Liquid Level Actuator is used to provide level-sensitive control of the sampler. The actuator can be used as a simplified alternative to a flow meter. The technical specifications, controls, and connectors of the 3700R/3740 are listed in Table1-1. Refer to Figure 2-6 for a picture of the controls and connectors.

3700R/3740 Refrigerated Sampler Section 2 Setup and Operating Procedures 2.1 Summary of Setup Procedure The following sections detail the preparations made before using the refrigerator: 1. Install the sampler. The suction line can extend to a liquid source up to 99 feet from the sampler, note that the maximum lift for the peristaltic pump with either the Teflon or vinyl line is 26 feet.
3700R/3740 Refrigerated Sampler Section 2 Setup and Operating Procedures Cut the line to the shortest length feasible: this aids the downhill routing. Avoid loops of coiled suction line which may hold residual amounts of liquid which would cross contaminate sample volumes. A shorter line will also extend battery life and pump tube life because a shorter pumping cycle is used to deliver the sample volume. 2.2.
3700R/3740 Refrigerated Sampler Section 2 Setup and Operating Procedures 2.2.2 Attaching the Teflon Suction The Teflon line is attached to the pump tubing by inserting the line into the pump tubing and securing it with a suitable clamp. 2.2.3 Strainers The 3/8 inch ID vinyl suction lines are shipped from the factory with our standard weighted polypropylene strainer (Figure 2-3) installed on one end of the suction line and a tubing coupling on the other end.
3700R/3740 Refrigerated Sampler Section 2 Setup and Operating Procedures 2.2.4 Intake Placement The proper placement of the sampler intake assures the collection of representative samples. The intake should be placed in the main flow, not in an eddy or at the edge of flow. The vertical position of the intake in the flow is important. An intake at the bottom may result in excess heavy solids and no floating materials, while placement at the top may result in the opposite. 2.2.

3700R/3740 Refrigerated Sampler Section 2 Setup and Operating Procedures 2.5.6 Single Bottle Composite Sampling Two and one-half (2.5) gallon glass and plastic containers are available from Teledyne Isco for composite sampling. Each container lid has a hole for routing the pump tube into the container to keep the pump tube from vibrating. When using the single bottle, remove the distributor arm and bottle rack.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines This section discusses in detail the sampling features of the 3700R Sampler and the procedures for programming your sampler. Teledyne Isco has found that the most effective way to learn to program the sampler is to read this section with a sampler in front of you. The time that you spend in the office or laboratory actually programming the sampler and observing its operation is usually time well spent.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines • The Run State section discusses what is occurring when your sampler is operating in the run state. 3.1 Description of Sampling Operation 3.1.1 Sample Events and the Sampling Cycle This information introduces the types of sampling performed by the 3700R and the terminology that describes those capabilities. A sample event is the complete cycle involved in taking a sample.
00R/3740 Refrigerated Sampler Section 3 Programming Guidelines You can characterize sample types by sample distribution and sample pacing. Sample distribution is the order in which samples are placed in the bottles. Sample pacing is the interval between samples. 3.2.1 Types of Sample Pacing There are two types of sample pacing: time-pacing and flow-pacing. In time-paced sampling, the interval between samples is a time interval.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines You can combine the types of sample pacing and sample distribution. Thus, you can take time- or flow-paced sequential samples and time- or flow-paced composite samples. Each combination of pacing is noted below. Time-Paced Sequential – In a time-paced sequential sample, samples are collected at equal increments of time. Each bottle receives one sample.

(The programmed number of bottles is a bottle set; as many as 24 bottles can be used.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines 3.3 Types of Sampling Available in Extended Programming Mode The extended programming mode expands the variations of sample pacing and distribution. The extended features listed below are used in more complex sampling routines. Note, however, that the sampling capabilities described in the Section 3.2 are available in both the basic and the extended programming modes.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines number of samples. This allows you to control the number of samples in each bottle. When you switch bottles or sets on a time basis, the total volume of each bottle or bottle set may vary in samples-per-bottle multiplexing. 3.3.3 Multiple-Bottle Compositing The extended programming mode offers a third multiplexing possibility: multiple-bottle compositing.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines 3.4.1 Storm-Event Sample Distribution Schemes A bottle group can consist of one or more bottles. Thus, the first-flush sample can be a large sample delivered to a single bottle or distributed to several bottles with a multiplexing scheme.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Standby State – In the standby state, the sampler is waiting for your instructions. From standby, you can start a sampling routine, placing the sampler in the run state. You can also access the interactive state, which is discussed in an upcoming section. Run State – In the run state, the sampler is executing the sampling routine and operating under program control.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Extended Programming – The extended programming mode increases the number of available features, making more complex sampling routines possible. For example, you can use nonuniform time intervals, and create an intermittent sampling schedule with the Stops and Resumes feature.

3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Note If you will be using very short sample intervals, be sure the interval is longer than the duration of the sampling cycle. For truly representative sampling, the interval in either time- or flow-paced sampling should be longer than the duration of the sampling cycle. If the intervals are too short, you will not miss any sample events, although some events will occur at improper times.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines If you are using bottles-per-sample multiplexing to add preservatives to consecutive samples, be sure to consider the volume of the preservative into account. Suction Head- You can configure the sampler, through the Liquid Detector configure option, to add the suction-head setting to the program sequence. The suction-head display will appear after you enter the sample volume.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Before programming the sampler – E s p e c i a l l y i f y o u a r e unfamiliar with the settings used in the previous routine, or if the settings have been changed, verify the configure-option settings. You must change the settings if they do not match your bottle size or the suction line used with your unit.

3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines 3.12 Stormwater Sampling Many stormwater runoff monitoring permits require a first-flush grab sample within the first 30 minutes of the storm event and a time- or flow-paced composite sample during the remainder of the event. The 3700 Sampler’s STORM pacing is ideal for monitoring storm events. Storm pacing allows you to: • Divide the sampler’s bottles into two groups. The first bottle group receives the first flush grab sample.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines • How to start and restart the monitoring installation Equipment Checklist – The equipment listed below is suggested for typical storm-event monitoring: • 3700 Sampler and power source.

3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines How to allocate bottles to the bottle groups – Use the next three displays to determine the both the sample distribution and the number of bottles allocated to the bottle groups. TAKE 2 TIMED SAMPLE EVENTS (1 - MAX) Display #23 3 BOTTLES PER SAMPLE EVENT (1 - MAX) Display #30 1 SAMPLES PER BOTTLE(1 - MAX) Display #31 A bottle group can contain one or more bottles. You can allocate all bottles but one to the first bottle group.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines After you’ve completed the entries for the first bottle group, the sampler will present the following message: -- BOTTLES, ----- ml AVAILABLE This message marks the beginning of the second section. It reports the number of bottles allocated for the second bottle group and the total volume of their combined capacity.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines For example, if the delay to the first group were 0 and the routine required two timed sample events at 30-minute intervals, the sampler would take 30 minutes to fill the first bottle group. The first sample event would occur after the programmed delay to group sample; the second sample event would occur 30 minutes later. Use Display #24 to enter the time interval for the second bottle group.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines has not been adjusted to reflect the higher rate. If this occurs, the sampler will continue the first bottle group until all samples have been taken. You can adjust the pulse interval by • Reprogramming the flow meter to change the number of flow pulses sent to the sampler by the flow meter. • Reprogramming the sampler to change the flow pulse interval in the flow-pacing segment of the STORM routine.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Depending on whether the second bottle group is time paced or flow paced, the third delay period will be either the delay to second group sample or the “During/After” delay. • Delay-to-Start Time. The start time is simply the time the sampler begins the routine. The sampler begins timing the delay-to-start time when you press the start sampling key.
3700R/3740 Refrigerated Sampler Section 3 Programming Guidelines Figure 3-18 Start Time Diagram for STORM Routines Note Before programming a sampler in the extended programming mode, the sampler must be configured for extended programming.

3700R/3740 Refrigerated Sampler Appendix D Calculating Flow Increment Between Samples The 3700R Sampler will accept flow-proportional inputs from an external flow meter or flow logger. These electronic flow-input signals are transmitted to the sampler at fixed increments of total flow, for example, every 10,000 gallons. Each time 10,000 gallons of liquid flows past the flow meter, it sends a signal to the sampler, which registers it as a single flow pulse.
3700R/3740 Refrigerated Sampler Appendix D Calculating Flow Increment Between Samples Calculation of Number of Flow Pulses – O n c e t h e d e s i r e d flow increment between samples is known, the number of flow pulses to be programmed into the sampler may be calculated, assuming that the volume of the flow pulses from the flow meter is known. The number of flow pulses is calculated by dividing the flow increment between samples by the volume of each flow pulse.
3700R/3740 Refrigerated Sampler Appendix D Calculating Flow Increment Between Samples Sample Volume Considerations – Thus, a sample volume of 188 ml will result in the desired composite sample. Because of the basic uncertainty of the delivered sample volume exactly matching the programmed nominal sample volume and the 10 ml sample repeatability, it is good practice to select a nominal sample volume which is slightly smaller than the calculated sample volume.

3700R/3740 Refrigerated Sampler Appendix E Glossary Bottles per sample – Bottles per sample is the number of bottles receiving sample volumes at each sample event. Composite sampling – In composite sampling, multiple sample volumes are placed in bottle sets. Typically, composite sampling uses a single container. A composite sample represents an average of the characteristics of the flow stream for the elapsed time of sampling.
3700R/3740 Refrigerated Sampler Appendix E Glossary Sample volume – The sample volume is the discrete, programmed amount of sample delivered to each bottle. A single sample event may deliver several sample volumes. Samples per bottle – Samples per bottle is the number of discrete sample volumes placed in each bottle. Sampling program – See sampling routine.
