Selecting a Chamber:
Because the change rates in the specifications are flexible, you have a choice of selecting a slower system  to save cost and utilities, or a faster system to shorten testing time.

In order for WIST to select the proper heating/cooling subsystems, we will need to know:

• Chamber interior space required
• Total mass of modules and supporting racks to be tested
• Desired heat & cooling rates (Otherwise WIST will quote systems to meet both minimum or maximum rates allowed by IEC.)
• Lengthy IEC and UL Tests
• All three of the IEC 61215 & 61646 environmental tests WIST chambers are used for can be done in the same test chamber. It may be better, however, to consider multiple chambers to save time and electricity due to the lengths of the tests:
• The temperature cycling test may last up to seven weeks.
• The damp heat test is six weeks long.

Product Details:

WIST -Insect rearing chambers are equipped with microprocessor-based temperature controllers, each offering dual digital displays (actual value and set value), straightline PID control, audible high/low alarms, and remote alarm connections. Our reach-in chambers employ thermoelectric cooling, and a high capacity circulation system to ensure uniform air distribution and exceptional uniformity from top to bottom throughout the chamber. Thermoelectric cooling offers exceptional reliability, completely eliminating refrigeration leaks and compressor failures, with a mean life expectancy of more than 15 years per unit. Standard temperature range is 18c-32, but extended temperature ranges available upon request. We also offer a 80c high temp decon cycle to kill of mites or other parasites.

Product Details:

An environmental chamber, also called a climatic chamber or climate chamber, is an enclosure used to test the effects of specified environmental conditions on biological items, industrial products, materials, and electronic devices and components.

Such a chamber can be used:

• As a stand-alone test for environmental effects on test specimens
• As preparation of test specimens for further physical tests or chemical tests
• As environmental conditions for conducting testing of specimens.

Product Details:

A Freeze-Thaw Chamber is a specialized testing equipment designed to subject products or materials to repeated cycles of freezing and thawing. This type of testing is particularly crucial in industries such as pharmaceuticals, biotechnology, and materials science, where products may be exposed to fluctuating temperatures during transportation, storage, or actual use. Here's a description of how Freeze-Thaw Chamber testing works:

Temperature Cycling:

• The primary function of a Freeze-Thaw Chamber is to subject the test specimens to alternating cycles of freezing and thawing. The chamber is equipped with a temperature control system capable of achieving and maintaining both freezing and thawing conditions.

Controlled Freezing:

• The chamber can create and maintain low temperatures, typically ranging from sub-zero to below freezing, replicating cold storage or transport conditions.
• During the freezing phase, the temperature inside the chamber is lowered gradually or rapidly, depending on the testing requirements.

Controlled Thawing:

• The chamber can simulate thawing conditions by raising the temperature back to ambient or above, mimicking the process of transitioning from frozen to unfrozen states.
• Thawing is controlled to avoid abrupt temperature changes, which can impact the integrity of the tested materials.

Cycle Repetition:

• Freeze-Thaw testing involves subjecting the specimens to a predefined number of cycles, with each cycle typically consisting of a freezing period followed by a thawing period.
• The number of cycles and the duration of each phase can be customized based on industry standards, regulatory requirements, or specific product conditions.

Monitoring and Control:

• The chamber is equipped with a monitoring and control system that ensures precise temperature control during both freezing and thawing phases.
• Temperature sensors continuously monitor conditions inside the chamber, and feedback mechanisms adjust the environmental parameters accordingly.

Uniformity of Conditions:

• Freeze-Thaw Chambers are designed to maintain uniform temperature and humidity conditions throughout the chamber to ensure consistent testing across all specimens.
• Air circulation systems help distribute temperature evenly, preventing localized variations.

Rate of Temperature Change:

• The rate at which the chamber transitions between freezing and thawing conditions can impact the stress placed on the tested materials. Controlled and defined rates of temperature change are typically specified to simulate realistic conditions.

Product Details:

Freeze Thaw Chamber or Cyclic Temperature stress tests are designed on the knowledge of the product so as to mimic likely storage conditions. The period of cycle is mostly considered 24 hours since the diurnal rhythm on earth is 24 hours. Additionally, the distribution environment can vary greatly, especially when a drug product is shipped between various climatic zones. Seasonal changes, mode of transportation, and the number of drop-off points are also variables that should be considered within the pharmaceuticalsupply chain. Drug products requiring controlled-temperature storage conditions must be distributed in a manner that ensures that the product quality will not be adversely affected. With the exception of short transit times within the same climatic zone, it is virtually impossible to validate a shipping method against all environmental conditions. Therefore, distribution stability studies are designed to generate additional data to complement preformulation development and routine (ICH) Q1A(R2).
