The machines are designed to meet the challenging to all the biotechnology, biochemistry, microbiology and engineering laboratories that have a constant requirement of storing the chemical and biological samples in deep freezers.

Presto’s Ultra-Low-Temperature Deep Freezer provides an approach to test the mechanical behavior of rubbers or polymers at low temperatures.

The primary stages of the test method involve ascertaining an acceptable technique for testing at low temperatures. The very first step to specify the temperature and the time to expose the test sample. It has been established that any one or more of the following dissimilar changes can take place to lower the test temperature.
