Frequently Asked Questions

For products that should be kept refrigerated or frozen, the following temperatures ranges are indicated.
0°C-10°C, <0°C, -20°C, -80°C
Products should be completely used as soon as possible even when kept within the specified temperature range. Where no specific instructions are noted, products should as a general rule be kept in a dark place at a temperature of less than 15°C.

As a principle, there is no expiry date or guarantee time for reagents. Any reagent can have problems as a result of storage conditions or a small amount of impurities. These minor factors can cause unexpected decomposition of the product over time. Therefore, it is difficult for us to create an expiry date for reagents. Please use products promptly upon receipt.

This is because required temperature conditions for keeping products and transporting products are not always the same.
