Technical Data Machine type designation: AS 200 tap Use in accordance with the intended purpose This device is not designed as a production machine or for continuous operation, but as laboratory apparatus for single-shift 8-hour operation.
Emissions Noise characteristics: Measurement of noise in accordance with DIN 45635-031-01-KL3 The noise characteristics depend on the set amplitude or sieve base acceleration, the number of sieves and the type of the material being sieved.
Transport and Installation Packaging The packaging has been adapted to the transport route and conforms to the generally applicable packaging guidelines. Please keep the packaging for the duration of the guarantee period because returning the equipment in unsuitable packaging if you have a complaint can jeopardize your guarantee claims.
Maximum relative humidity 80% at temperatures up to 31°C, with a decrease to 50% relative humidity at 40°C. At high air humidity the electrical and mechanical components can become damaged and performance data can change to an unknown extent. Installation height : max. 2000 m above sea level Installation Install the AS 200 tap only on a stable, safe surface in order to prevent the transmission of undesirable vibrations.

Operating the AS 200 tap Switching on and off The main switch is located on the left side at the back of the AS 200 tap Turn on the main switch - - lights up in the time min display The STOP LED lights up The AS 200 tap is now ready for operation without interval and in continuous operation at a speed of 50 min-1. Display and operating element The + button increases the sieving time in the range from 1 – 99 min. The – button reduces the sieving time, and the range from 1 – 99 min is shown in the display.
Setting the time and continuous operation When the AS 200 tap is switched on, the sieving time still has to be determined. Two dashes - - appear in the display 13. Increasing the time: Button 13 increases the time up to 99 minutes. Reducing the time: Button 12 reduces the time down to one minute. Continuous operation: 12 13 14 If the time drops below one minute, two dashes will appear in the display. This activates continuous operation. The same happens when the time exceeds 99 minutes.
Inserting the sieve stack The AS 200 tap is suitable for analytical sieves with outside diameters of 200 mm and 203 mm (8“). To make it possible to loosen the clamping screws easily, the position of the KH clamping lever can be adjusted independently of the clamping screws. Then unscrew the two clamping screws C and push the carriage downwards. Tighten both clamping screws firmly again. KH Place the sieve stack in the centre of the carriage and loosen the two clamping screws.
Removing the sieve stack To remove the sieve stack, lift it and the lid upwards slightly and at the same time press the tapping arm upwards. Pull the sieve stack forwards and out. 8 January 2008 Retsch GmbH 16 Doc. no. D 98.025.
Retsch Analytical Sieves Analytical sieves with diameters of 200 and 203 mm Initially, the new RETSCH sieves will be available in the three versions that are the most important for sophisticated laboratory analysis: 200 x 25 mm 200 x 50 mm 203 x 50 mm = 8“ x 2“ Compatibility with other standard sieves is ensured of course. The new sieves are compatible with the standard RETSCH range of sieves and can also be combined easily with most other sieve makes.
Working Instructions Sieving aids For materials that are difficult to separate we recommend the additional use of sieving aids in the individual sieve fractions. For this purpose and depending on the mesh size of the sieve and the preselected oscillation intensity, balls of agate, rubber, porcelain or nylon brushes and Vulkollan® cubes can be used. See also the table below.
EasySieve Control, evaluation, documentation EasySieve®, the software for grain size analysis from RETSCH, is far superior to manual evaluation in many respects. This is because the software is able to conduct measuring and weighing operations automatically – from registering the weights of the sieves to evaluating the data. This can be accomplished more easily and more conveniently than ever before, which is why it’s called “easy”.
General Points Cleaning We recommend Retsch ultrasonic baths for a thorough but gentle time-saving cleaning of your analytical sieves. Please ask for our special leaflet on the “Care and Cleaning of Analytical Sieves“, which is available free of charge. The AS 200 tap may not be cleaned with running water. Risk of a fatal electric shock. Use only a cloth moistened with water. Solvents are not permitted. Maintenance Otherwise the AS 200 tap is essentially maintenance-free.
