Description

The mall specializes in producing and selling high-purity experimental products for "scientific research institutes, universities and other" scientific research institutions and laboratories. For experiments, we should buy high-cost and high-purity products instead of low-cost and low-purity products. We should buy according to the actual use. Although the purity of industrial products looks the same. We should avoid low purity industrial products entering the laboratory, which will affect the accuracy of experimental results.

3. Pretreatment method (recommended)

N117 membrane can be pretreated before use. The specific method is as follows:

First, treat 5% hydrogen peroxide at 80 ℃ for 1 hour, then soak in deionized water for half an hour, then boil 5% dilute sulfuric acid (mass ratio) at 80 ℃ for 1 hour, and finally soak in deionized water for half an hour.

Or it can be used only after soaking in electrolyte solution according to the established habits of users.
