SPEX Freezer/Mill

The SPEX Freezer/Mill® is capable of grinding plastics and polymers into powder, while avoiding thermal degradation.
spex-6870-freezer-millThe milling of materials that suffer from the impact of heat during the milling process can be very difficult to grind into powders. These materials tend to smear as they heat up forming a paste rather than a powder. Milling under cryogenic conditions prevents the sample becoming soft, in fact it makes the sample brittle, making milling of these materials far simpler.
These SPEX cryogenic laboratory mills cool samples in a grinding vial to cryogenic temperatures then pulverize them by magnetically shuttling a steel impactor back and forth against two stationary end plugs. Since the vial is closed, the integrity of its contents is maintained, hazardous or critical samples are easily controlled, clean-up is simplified and cross-sample contamination is eliminated.
The vials are kept cool by liquid nitrogen throughout the grinding cycle which keeps the sample at cryogenic temperatures preserving its key aspects.
A touch screen control panel allows up to 10 user-defined grinding programs for simple and fast recall.
A choice of vial sizes are available to grind different sample sizes or to grind multiple samples simultaneously.

Temperature Calibration


Why is temperature calibration necessary?
All thermometers need to be characterized or calibrated. In industry the need to calibrate is often very real and practical.
No thermometer will remain entirely constant, thermometer and sensors such a Mercury-in-glass (MIG), Thermocouples (T/C), Thermistors, Resistance Thermometers (RTD) change their characteristics with time, temperature cycling and they can become contaminated.
There is a need to calibrate to meet Quality Standards, which for medical and safety applications may be vital to safeguard life. Calibration can improve efficiency, often if a thermometer’s characteristics are known more accurately savings in cost can be made. The requirement to calibrate temperature sensors continues to grow.
Isothermal Technology has focused on providing calibration solutions for the calibration of all types of thermometers.



Isotech manufactures a comprehensive range of temperature calibration products, including Standard Platinum Resistance Thermometers, Portable Dry Block Calibrators, Thermocouple Referencing and associated equipment used in laboratories throughout the world.
