Determination of Cold and Hot Spot in Stability Chambers

Back in the day, pharmaceutical companies have made a huge leap forward. When storing the drugs in one way or another may be exposed to a variety of factors, affecting the quality and lead to a change of properties. By destroying the main parameters include increased storage temperature, the action of light, moisture content oxygen or carbon dioxide in the air, the impact microorganisms and so the packaging structure etc. Determination of the effect these factors – one of the most important tasks of the service control quality to the pharmaceutical industry. Climate chambers with humidity control allow you to test the stability of pharmaceuticals, cosmetics, and food substances in accordance with international standards of the pharmaceutical industries.

Climate chambers – devices, specially designed for the simulation of complex weather conditions with extremes of temperature and humidity, as well as maintaining constant conditions for long period of time They operate at a temperature from -70C to + 200C. In addition to maintaining the temperature and humidity chamber can be equipped with lighting and CO2 supply systems. The task of any climatic chamber -to create and maintain a climate with given parameters of temperature and humidity. Special attention is paid to these cells equally distribution of temperature and humidity throughout the volume of the working chamber. Each climate chamber must be tested to meet strict standards and be equipped with all the security features.

In these cells maintain a temperature lower than ambient temperature medium (from 0 C to + 70C) is provided by using a Peltier thermoelectric elements. This allows dispensing with the traditional refrigeration systems. Peltier elements consume 2 – 5 times less energy than freon refrigeration systems, and during their operation no noise and vibration.

Not least the fact that these cells are excluded icing and over drying samples. Heating and cooling systems are located in the chamber air jacket that surrounds the working chamber. It provides fast and accurate temperature control.

In testing climatic chambers are created ideal conditions for temperature and climatic tests. Programming by means of profiles, an active moisturizing and drying (10 to 98% relative humidity) in combination with accurate temperature control from -42 to 190C (without humidity control), or from 10C to 95C (with humidity control) provide opportunities test materials and artificial aging tests.

All components of the climate system perfectly interact with each other, it provides a fast, accurate and cost-effective change in temperature. Electronic coolant injection system ensures optimum cooling performance, and thanks to the automatic defrosting stability chamber can conduct long-term trials without interruption.

The high quality of stability chamber confirmed heating and cooling time Thus, the test cells are cooled from 180 C to -40 C for about 95 minutes, and the reverse heating time is only 20 minutes. Thus hot and cold spot in stability chamber has a huge number of advantages as compared: 1) Comfortable design for operation and maintenance; 2) High-precision temperature control system; 3) Easy and intuitive user control; 4) Optimum air flow for cameras of all sizes; 5) Independent protection unit at the maximum/minimum temperature; 6) Minimum noise; 7) The possibility of combining up to 32 cameras in a single computer network (including connecting to the Internet). In our time stability chamber – the very much needed acquisition for each of the pharmaceutical laboratories.
