医用保存冰箱如何选择
When buying a new freezer the user should consider what it is to be used for and how they intend using it. This may appear obvious but the use of freezers that are not fit for use and unsuitable operating practis are regularly seen.
在购买一个新的冰箱时，用户需要考虑其预计用途和将被如何使用。这看起来理当然，但是使用不适用的冰箱和不适于操作的情况屡见不鲜。
The intended use will determine the extent to which a particular freezer design meets your needs, or if any special measures need to be put in pla. Consideration should be given to what temperature range you require, with a diversity of freezer models being available that maintain a variety of frozen temperatures. Storage conditions for specific medicines may be found by referen to packaging details or the Summary of Product Characteristics available from the manufacturers’ medicines regulatory authority or from the manufacturer. Topics you may wish to consider are presented in Table 1.
预期用途将决定一个特定冰箱设计符合你的需求的程度，或者是否需要实施任何具体措施。由于不同类型的冰箱可以维持不同的冷冻温度，因此需要考虑你需要的温度范围是多少。具体的储存条件可以参考厂家或厂家监管提供的包装说明或者产品特性总结得到。你希望的考虑点罗列如下：
Domestic refrigerator i box （+ves）
家用冰箱（优点）
· Readily available
· 现成方便
· Relatively cheap.
· 相对便宜

· 使用家用冰箱会限制维持温度的能力
The inherent disadvantages outweigh any advantage for use in GxP to the extent that use of refrigerator i boxes is not supported in any circumstan.
其固有的缺点远远超过任何优点，因此家用冰箱不适用于任何GxP环境。
