Temperature Control – Melting

ETCS-761/762 Peltier Thermostatted Single Position Cell Holder (Water-Cooled)

These cell holders use the Peltier effect to precisely maintain the sample temperature. The cell holders include a stirrer for uniform cell temperature. The ETCS-761 and ETCS-762 cell holders are water cooled Peltier accessories for a greater temperature range.

OPS-512 Optional Temperature Sensor for EHCS-760
OPS-512 OP sensor for direct temperature measurement in the sample cell for both the ETCS-761 or ETCS-762.

PAC-743R Automatic 6/8-Position Peltier Cell Changer (Water-Cooled and Water-Cooled with Thermostatted Reference)

The PAC-743 and PAC-743R automatic 6/8-Position Peltier cell changers are used for temperature controlled transmittance and absorbance measurements with multiple sample cells, with a variable temperature range from 0 to 100ºC.

Three cell block types are available: a 6-position 10 mm cell block, an 8-position micro cell block and an 8-position 5 mm cell block.

Using the 8-position micro cell block up to 8 samples can be simultaneously transferred directly from a 96 micro-titer plate (8×12) using an 8-way micro-pipette.

The PAC-743R also includes a temperature controlled reference position.
