About Handling

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.

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

This is because instead of actually measured values we may list values from the relevant literature. The properties listed in the online catalog are not standardized values and should only be used for reference. Where values from relevant literature are used, (Lit.) is printed after the value.

With the exception of products for which such usage is specifically noted including food coloring as determined under the food sanitation law (our company’s product grade for such products is FC) and basic ingredients for pharmaceuticals (mainly chemical products), reagents and chemical products included in the catalog cannot be used for purposes other than experiments or research and should not be used as pharmaceuticals, quasi-pharmaceuticals, cosmetics, agricultural chemicals, insecticides, food additives or chemical agents for domestic use. TCI bears no responsibility for compensating any accidents or injuries resulting from mistaken use of our products.
