什么是使用环境测试室？
环境测试室are designed to maintain user-specified atmospheric conditions, through temperature, humidity, airflow, and light cycling controls, for stability and shelf-life testing of pharmaceuticals, cosmetics, raw materials or food products.
测试室准则和标准
The guidelines for product stability testing are published by the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use, or ICH. The ICH’s guidelines define acceptable temperature and humidity ranges, deviations from setpoints, length of testing intervals, and uniformity across the internal chamber.
Stability Test Chamber Construction Material
Depending upon the intended use of the product, stability testing durations may range from several days to one year. As such, environmental test chambers are built with durable painted-steel exteriors and aseptic, rigid stainless steel interiors to handle the rigors of long-term testing.
测试室气流
为了确保整个测试区域的最佳均匀性，环境测试室的设计使用水平层流气流系统，其中包括腔室一侧的正压进料室和另一侧的负压返回全体。

A-环境测试室应用
(back to chart)
环境测试室are designed for four primary applications: humidity chambers, climate test chambers, photostability chambers, and growth chambers. Humidity chambers are designed to control temperatures from ambient to, most commonly, 70°C and humidity levels from 10% to 98% RH.
湿度测试室包括冷却线圈以降低内部温度至冷藏水平（4°C）。气候测试室的温度范围比湿度测试室的温度范围更大，通常为-40°C至180°C，以模拟极端的环境条件。
光稳定性室包括紫外线和荧光灯，以将药物或化妆品样品暴露于不同的管腔剂量。
植物生长室control temperature and humidity to simulate optimal growth conditions for plant organisms, like Arabidopsis, or seed germination studies.
B-最高测试室温度
(back to chart)
标准环境测试室保持从环境到70°C的温度，尽管某些模型利用冷却线圈将温度降低至4°C。
生长chambers旨在模拟种子和植物生物的最佳发芽条件，因此无法维持50°C以上的温度。
Climate testing chambers在该行业中提供最大的温度范围，通常为-40°C至180°C。
C - Environmental Test Chamber Size and Capacity
(back to chart)
环境测试室根据样品存储容量制造到标准尺寸的标准范围。
Compact, low-throughput models提供2立方英尺或4立方英尺的存储空间，而高通量，独立的单元可提供多达29英尺的存储空间。
标准测试室include adjustable shelves installed on steel racks to maximize sample storage capacity within the internal chamber.
Given the side-mounted plenums external to the inside chamber space, the working footprint of the test chamber is significantly larger than the storage capacity.
D - Environmental Test Chamber Voltage
(back to chart)
120-volt connections are suitable for standard laboratory power outlets in the United States.
240-volt connections, common in Mainland Europe, require less current (amperage) and smaller conductors than equipment designed to operate at 120-volt.
Specialty high-voltage equipment requires 480-volt connections and carries additional protection against electrical hazards.
E - Environmental Chamber Interior Material
(back to chart)
Stainless steel is compatible with alcohol-based cleaners, resists corrosion, and promotes aseptic conditions. Powder-coated steel represents an economical alternative to stainless steel but may chip after prolonged exposure to bleach-based disinfectants.
F - Special Environmental Test Chamber Features
(back to chart)
F1-冷藏环境测试室离子
冷藏测试室将温度降低至4°C，以进行保质期测试或药物的稳定性测试。冷藏模型还可以用作适用于温度敏感食品和原材料的短期存储空间。
F2-湿度控制测试室
湿度测试室将RH水平从10％到98％，每个ICH指南。如果温度或湿度条件不在标准范围之内，视觉和听觉警报会激活。
F3 - Diurnal Light Cycling Chambers for Plants
植物生长室含有荧光灯，用于在一周内定义的编程日常光明和黑暗（或白天/夜）周期。
F4 - Touchscreen Environmental Controller
人体工程学触摸屏控制器包括时间分段，实时编程，数据记录和导出，系统诊断测试以及听觉/视觉警报。
F5-测试室的轻剂量控制
一定的耐光性室包括光dosa医生ge control for UV-A and fluorescent, visible light per ICH guidelines.
