1) Heater block: can warm up to 25 samples.

2) Power LED indicator2) Power LED indicator

2) Power LED indicator: Lights when the power button on

the back of the instrument is switched ON.

3) Heating LED indicator3) Heating LED indicator

3) Heating LED indicator: Lights only when the heater is

working (warming up). When the indicator cycles ON and

OFF, the heater is maintaining stable the set temperature.

4) Temperature mode switch4) Temperature mode switch

4) Temperature mode switch: Selects 105 or 150 ºC (221

or 302 ºF) operation mode.

5) Timer5) Timer

5) Timer: The knob allows to control the heating procedure.

It is possible to choose:

Timed procedure modeTimed procedure mode

Timed procedure mode: when the timer is set

between 0 and 120 minutes, the heater will main-

tain constant the selected temperature for the

remaining time. The reactor will shut off at the end

of the elapsed time and will inform the user with an

acoustic alarm.

infinity mode: the heating indicator will light

when the heater is operating. The heater block will

remain at the selected temperature as long as the

instrument power is ON.

REAR PANEL

Set the power switch (back of the instrument) to ON

position. The power indicator will light. Set the tempera-

ture switch to 105 or 150 ºC (according to the procedure

described in the manual of the specific parameter).

Position the timer to the ∞ position by turning the knob

anticlock-wise to allow the heater to operate; the heating

indicator will light. Allow the heater block to warm up for

approximately 30-40 minutes, depending on the set tem-

perature. During this period the heating indicator will

remain ON.

When the heating indicator cycles ON and OFF, it means

that the heater has reached the set temperature and is

maintaining it constant.

At this moment it is possible to start a timed procedure

and select the time interval requested by the specific

parameter digestion procedure by turning the knob clock-

wise. During this procedure the heating indicator will cycle

ON and OFF.

Attention: to assure a correct digestion it is important to

start the timed procedure as soon as the heater is stabi-

lized at the selected temperature (that is when the

heating indicator starts to cycle ON and OFF).

Notes:

• Use of the optional safety shield is strongly recom-

mended to protect the operator from splattering reagents

in case of a vial should break.

• Do not place the Reactor near heating or cooling source.

Temperature stability could be affected.

• The set temperature is that typically expected into the

tubes. The temperature of the metallic block is a few

degrees higher than the set value, in order to allow the

heat transmission from the block to the liquid inside the

tubes.

• During operation, the block temperature will be slightly

different for block empty or full of vials. If cold tubes are

placed in the block, the temperature will decrease of

several degrees and a few minutes will be required to

recover as the tubes warm.

• An external stainless steel probe thermometer can be

used for a check of the block temperature, simply by

placing it into the appropriate receptacle.

MAINTENANCE

The instrument should be kept clean and any reagent spill

should be wiped up immediately.

Do not touch the heater block unless you are

certain it has cooled.

If some reagent accidentally spills into the heater

block, disconnect power and allow the instrument

to cool; then remove all tubes and clean the

block.

Should overheating occurs, the reactor automati-

cally shuts down. Both LED indicators turn off.

Contact your dealer or your nearest Hanna Service

Center for maintenance.

Fuse replacement

Replace fuse only with fuse of specified type and

current rating.

• Turn the instrument off before removing the fuse holder.

• Unscrew the fuse holder by rotating it counterclockwise.

• Replace the fuse with one 4A fuse for 115-volt model

or one 2A fuse for 230-volt model.

• Replace the holder before turning the instrument on.
