Products Description
The design, manufacture and application of the walk in cooling chamber strictly follow a series of international and domestic authoritative standards. In the pharmaceutical industry, we ensure regulatory compliance with drug storage and stability testing environments in accordance with ICH guidelines, World Health Organization (WHO) specifications, the UK Medicines and Health Products Regulatory Agency (MCA) and the US Food and Drug Administration (USFDA). For example, drug stability tests need to simulate long-term storage conditions (25 ° C ±2 ° C, 60% RH± 5%RH) and acceleration conditions (40 ° C ±2 ° C, 75% RH± 5%RH), and the test chamber's accurate temperature and humidity control capabilities ensure test compliance.
Products Description

Scientific research institutions have very high requirements for the test environment in the aspects of material research and biological experiments. In the research on the low temperature properties of materials, in order to explore the changes in the mechanical properties of new alloy materials at low temperatures, it is necessary to accurately control the temperature by using a walk in cooling chamber according to relevant material science research norms, simulate extreme environments such as polar low temperatures, test the strength, toughness and other parameters of materials, and provide data support for the research and development and application of materials.
Common walk in cooling chamber temperature range can be as low as -70 ℃, up to room temperature. In BOTO's test chamber, for example, the temperature range covers -68 ° C to 85 ° C. In terms of accuracy, the temperature control accuracy can reach ±1℃, and some high-end products can even reach ±0.5℃. For example, in a low-temperature test for aeroengine parts, the temperature is required to be stable at -50 ° C ±0.5 ° C, and the test chamber can accurately maintain this temperature to ensure that the performance test data of the parts in the simulated high-altitude low-temperature environment is accurate and reliable.
Application field
Pharmaceutical industry: Used for drug stability testing, vaccine storage research, etc. By simulating different temperature and humidity conditions, the quality changes of drugs in the storage process were studied, and the shelf life and storage conditions of drugs were determined. For example, a pharmaceutical company uses a walk in cooling chamber to test the stability of a newly developed oral medicine to ensure the effectiveness and safety of the drug under specified storage conditions.
Electronic appliances: widely used in low temperature performance test of electronic products, aging test, etc. Test the starting performance, battery life and circuit stability of electronic products in low temperature environment. For example, in the stage of new product development, mobile phone manufacturers use test boxes to carry out low-temperature tests on mobile phones, optimize product design, and improve the applicability of products in cold areas.
Food cold chain: Help food preservation technology research, cold chain logistics equipment performance test. Simulate the low temperature environment of food in the process of transportation and storage, study the change of food quality, and optimize the cold chain logistics scheme. For example, food scientific research institutions use test boxes to test the impact of new fresh-keeping packaging on the fresh-keeping effect of fruits and vegetables in a low temperature environment.
