Section 1 Introduction

The product is dry bath with advanced microprocessor control, which
can be widely applied to sample reservation, enzyme reservation and
reaction, DNA amplification, electrophoresis degeneration and serum
coagulation, etc. Useful for variety of applications in molecular
biology and histology as well as clinical, environmental & industrial
settings, including restriction digests, denaturing DNA, BUN, melting
agar, coagulation studies, hybridization and Hot Start thermo-cycled
reaction. The dry baths feature a broad temperature range, up to
150°C, and excellent uniformity. A microprocessor regulates the high
wattage heater to provide precise, accurate control and rapid
heating. The Aluminum block chamber ensures an even transfer of
heat from the heating element to the block. Temperature is easily set
using arrow keys while the value is shown on the large display. The
user calibration function allows for easy calibration to in-house
standards when required. Interchangeable blocks are available to
accommodate a wide variety of tubes, plates and slides. Solid blocks
are also available for custom machining. Each dry bath is supplied
with a block lifter that enables the user to exchange blocks easily,
even when the block is hot.

The characteristics of the product are as follows:

 Large block 96x96x49mm
 Precise microprocessor control
 Broad temp. range, to 150°C (Optional: up to 250°C)
 Large digital controller with dual display
 User friendly calibration
 Rapid temperature increasing rate
 Optional: RS-232 communication.

Section 2 Safety

During operation, maintenance and repair of this instrument, the
following basic safety notes should be observed. In case of failure to
follow these instructions, the warnings or notes indicated herein, the
basic protection provided by the instrument, its safety criteria of
design and manufacture, and its predicted use range would be
impaired. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the equipment may be
impaired. MRC is not responsible for any injury as a result of the user’s
failure to observe the following requirements.

Caution This instrument is for indoor use.

a) The ground connection

To avoid the electric shock, the input power line must be
reliably grounded. The instrument is equipped with the three­pin plug that has the third pin (the pin connects the ground),
therefore, the plug should be used with the grounded power
socket only. This is a kind of safety device. If the plug cannot
be plugged into the power socket.

b) Servicing and Replacement of Parts

The operator should not take apart the instrument without
permission. Only qualified professionals are allowed to replace
elements or adjust components inside the instrument.
Replacement of components while unit is connected to power
and/or turned on is prohibited.

c) Observe voltage/power requirements

Before the instrument is connected with the AC power source,
the voltage of the power source should be the same with the
required voltage of the instrument (a deviation of 10% is
allowed). The rated load of the power socket should not be
lower than the requirements of the instrument.

d) The power cord

The instrument should use the power line cord attached to it. If
the power line is destroyed, it must be replaced but not be
repaired. The replacement should be carried out with the
power line of the same type and same specification. No items
should be put on the power cord when the instrument is in
operation.

e) Connecting and disconnecting from to power source

The user should hold the plug to remove from power source.
When connecting the plug, user should make sure it has been
fully plugged in; when removing the plug, do not pull the
power line forcefully.

f) Placement of the instrument

This instrument should be fixed in a low RH and low dust place
away from water source (e.g. sink or water pipeline) and the
room should be well ventilated, and free of corrosive gas or
interference of strong magnetic field. The instrument should
not be placed in a wet or dusty location. the openings on this
instrument are for ventilation circulation and in order to avoid
over-heat of the instrument body they should not be blocked
or covered. When a single set of instrument is used, the
interval between ventilation opening before and after the
instrument and its nearest object should not be less than
25cm. Also, don’t use the instrument on loose or soft surface,
or the air inlet of instrument bottom might be blocked.
Excessive temperature will impair performance or result in
failure of instrument. This instrument should not be used in
location subjected to direct sun light. The instrument should be
kept away from hot gas, oven and all other heat sources. If the
instrument is to be stored for a long time, the power plug
should be withdrawn and the instrument covered with soft
cloth or plastic film to avoid entrance of dust. The product is
powered by connecting the mains plug to a standard socket­outlet. Always place the product in such a way that it is easy for
the operator to disconnect the product from the mains supply.
