Examina Vacuum System

Examina Vacuum System

Features and Benefits

Based upon the proven low pressure and temperature control technology developed for the Freeze Drying System (FDCS196), Linkam has modified the stage body and temperature control element to extend the temperature range from -196C up to 350C at a vacuum of 10-3mbar using a simple 1.5L rotary vacuum pump.

It is now possible to carry out ultra low temperature experiments with virtually no gas or air contamination of the sample. By substituting a vacuum port for a gas valve it is also possible to first pull a vacuum and then bleed in the desired gas.

A prirani gauge can be supplied to relay the sample chamber pressure to either the Linksys 32 software or the display panel on the TMS94 temperature programmer.

By connecting the vacuum pump to the MV196 motorized valve, pressure can be quickly and accurately varied utilizing simple on screen software controls.

Contact Linkam to discuss your requirements.

The temperature is programmed by the standalone TMS94 temperature programmer. Sophisticated temperature profiles of up to 32 ramps can be set up with ranges of heating rates from 0.1C/min to 30C/min.

The TMS94 can be used as a standalone programmer or connected via RS232 to PC enabling use of further features within the Linksys 32 software.

TMS94 firmware can be updated via email using the RS232 connection.
