Advanced Dry Block Heaters with Heated Lid are designed for applications
that require repeatable results and superior temperature stability. These multi-
purpose units are ideal for isothermal incubation, enzyme reactions, immunoassays,
nucleic acid denaturation and a wide variety of other laboratory procedures. Integral
support rod holder with locking knob accepts optional External Temperature Probe
Kit. Optional External Temperature Probe Kit monitors actual block or sample
temperature. Block heater accepts (1) one microplate block or (2) two separate
interchangeable modular blocks, accommodating various tube sizes from 0.2mL
micro-tubes to test tubes or vials up to 85mm in height. Each block has a thermometer
well for measuring block temperature. Efficient heating due to close tube and- block
contact with a low density design for exceptional temperature uniformity. The heated
lid helps to regulate the temperature and reduce the amount of condensation on
sample lids. Heaters require VWR
®
modular heating blocks for operation. Modular
blocks are sold separately (see pages 66-68).
Operating Features:
Microprocessor control:
PID temperature control, with optional external RTD probe,
offers a temperature stability as low as ±0.1°C with a temperature uniformity as low
as ±0.1°C. Samples are heated to temperature quickly and accurately. Temperature
is adjusted in ±0.1°C increments.
LED display:
Touch pad controls with easy-to-read, independent LED displays for
temperature, and time. Provides repeatable and accurate results every time and is
easily visible across lab benches. Shows set-point and actual temperature. Timer
will display elapsed time or, when programmed to user defined limit,will shut off unit
when time reaches zero. Display will show last used settings, even after power has
been turned off.
Audible alarm:
In timed mode,alarm will sound when time reaches zero and when
unit reaches set-point temperature.
Temperature calibration mode:
Allows user to calibrate unit to an external temperature
device.
Safety Features:
Caution hot indicator:
Hot warning symbol light is illuminated when the temperature
is above 40°C.
Over shoot protection:
If the unit exceeds the set temperature by 10°C the unit will
automatically stop heating.
CAUTION!
To avoid possible electrical hazard, do not fill well or block
opening with water or other fluids. Unit is designed as a dry bath/incubator.
Operating Conditions:
Units can be run in environments from 18 to 33°C (64 to 91°F), 20% to 80%
relative humidity, non-condensing.
Applications:
Isothermal incubation, enzyme reactions, immunoassays and nucleic acid
denaturation.
Ordering Information
Units include a 92” (234cm) detachable, 3-wire cord and plug (230 volt units
are supplied with Euro type plug). 2 year limited warranty on parts and labor.
Optional temperature probe kit available (see page 63). Modular blocks are
sold separately (see pages 66-68).
