Hotpack 33FP


  • Stainless Steel interior and exterior
  • Accurate temperature control
  • Microprocessor based PID controls
  • StabilityPLUS™ Airflow
  • Solid door as standard



Hotpack model 33R is a high quality Temperature controlled Stability Chamber, built to exceed the exacting standards required by such regulatory bodies as ICH, TAPPI and MIL Spec.

The Stability Chamber is constructed from 304 Stainless Steel, with the exterior surface painted as extra protection. The interior is unpainted allowing easy cleaning. Each unit is supplied with 4 solid stainless steel shelves which locate into 4 pilasters, and these serve to hold the shelves rigid and bear the load of the samples being tested. There are 19 available shelf positions to allow high density testing or storage if required.

A microprocessor based PID controller allows extremely accurate temperature control and performance and ensures that the chamber performs well within the specified test limits. The controller also has user settable over- and under- temperature limits and audible/visual alarm systems which alert the user to events such as power interruptions.

The key to uniformity in any Temperature Controlled Chamber is the airflow, which ensures all parts of the chamber are constantly supplied with conditioned air at the correct temperature. The Stability PLUS™ design ensures there are no hot or cold spots anywhere in the chamber and the gentle nature of the airflow ensures that any uncovered samples are not blown away or subject to forced evaporation.

A wide range of optional accessories is available for the Temperature Controlled Chamber including access ports, PC interfaces and chart recorders.
