How to determine the correct selection of the test paper bucket, the appropriate test paper bucket should have the following characteristics:

1, first of all, as a container to store the test paper, the shelf life of the test paper plays an important role. We often pay much attention to the seal problem of test paper drum and neglect the stability problem. The quality stability of test paper drum batch and batch is the key to the stability of test paper. Just like the test paper, although the independent packaging is convenient, but the batch can not be controlled, the measurement results are likely to be different, the test paper bucket is the same, a good test paper bucket batch and batch error to reduce to the lowest, is the final result.

2. Second, the operation process of the machine is smooth. At present, most of the machines that use the drum test strip are European and American machines. A good test paper bucket has the same flow stability in different machines and reduces the production cost of single product

3. At present, there are 25 pieces/barrel packaging on the market, which are generally required to be used up in 2-3 months after unpacking. That is to say, the end customers are those who need long-term monitoring, that is, stable customer groups.
