About Us

NEOCHEMA`s leading idea is the satisfactory fulfilment of our customers` needs by prompt deliveries of high quality products.

As the quality of each result of analysis depends on the quality of the reference substances used, the great demands on the quality of our products are accounted for by a strict quality control of each product before it leaves our house and by fitting out each item with a certificate.

We inform you that for preserving the high quality of the products after they have left our house, the durability can be prolonged by careful handling and storing. This means especially protection against solar radiation, storage in a cool, dry place and the careful closure of ampoules already opened.

The conditions mentioned above apply in particular to the readily volatile CKW / BTX - standards.

Please remember also that the solvents used as well as the dissolved substances are toxic.
Therefore, precautions have to be taken when handling / working with them: wearing of one-way protective gloves, avoiding the inhalation of the fumes produced or even working in a fume hood.

This homepage presents the basic assortment of NEOCHEMA. On request, standards with different components, concentrations and solvents will be delivered within a short time.
