Temperature
Controller 
Our Temperature Controllers are designed to work with
different heating elements and a variety of optional accessories including
Dry
Bath, Water Bath, BLM
Cell Holder and Extruder
Warmer. Two modifications are available. TC-02A
can
be connected to high power AC heaters (lamps, heater fans, water immersed
heaters etc.) for large volume heating, or to compact heater
assemblies for temperature control of fluorometer cells, or microscope
stages. TC-12
version
is similar but smaller and have lower power, no AC and no recorder output.
Each
unit comes with one temperature sensors attached to 3 feet (90 cm) cables.
Second sensor assembly (Part # AD592)
is optonal and need to be purchased separately.

All
heater assemblies are attached to 4 feet (120 cm) cable with 2.1/5.5 mm
connector that match TC-12/TC-02A output. Heated surfaces are electrically
non conductive and can be mounted directly to metal surfaces using enclosed
hardware. Ceramic heaters can be used at maximum power without heat
sink (but with sufficient air cooling) and good for temperatures up to
+150oC. TO-XXX heating elements need good contact with
metal heat sink (use of silicone heat sink compound is recommended).
They can be irreversibly heat damaged if used unmounted. It is not
recommended to use them for heating to temperatures above +80oC.
Dry
Bath
This compact unit is designed to
work with TC-02A
or other temperature controllers that have 12-24 V output. Allow
keeping small number of microcentrifuge tubes (0.5-2 ml size) above room
temperature near your workspace. Two ceramic heating elements attached
to the bottom of massive aluminum alloy heating block provide even heat
distribution to up to 15-16 vials. (One-two well should be reserved
for feedback temperature sensor and thermometer).

Water
Bath
Micro Water Bath is the another
option for keeping samples close to the workplace and at required temperature.
This attachment has water immersed heater and a dry well for temperature
sensor. Fill it with water, place on top of a magnetic stirrer (not
included) and connect to TC-02A
controller, and you have compact, simple and reliable bath for different
kind of lab tubes or small flask.

Series Objective Heaters provide a simple and effective method for reducing
thermal gradient between objective and specimen. Designed to work
with TC-12 temperature controller (TC-02
can be used as well). Objective Heater represent collar that attaches to
microscope objective. This collar incorporates a resistor block and
holder for AD592 feedback temperature sensor.
When connected to TC-12 controller, electronic
controls maintain the objective at a constant pre set temperature.
To determine which heater is right for your objective:
1. Measure the length of the objective cilindrical part
were heater to be mounted. For standard heaters it should be 12 mm
or more. If it is less than 12 mm you need custom made heater.
2. Measure the body diameter of the objective near the
lens end.
With these measurements choose the objective heater from
the table below. Custom designs are also available.
