Your benefits

Your benefits at a glance

Everything from one source

Comprehensive product range

Our comprehensive range of quality laboratory glassware like microscope slides, cover glass, counting chambers, capillary tubes, laboratory containers and volumetric glassware has made our name and our brand renowned internationally. Many products made of plastics and porcelain for the general laboratory work complement our range of laboratory glassware.

We recommend our customers to purchase complete multipacks. Take advantage of scaled prices geared to the quantities of multipacks. Economize the freight charges for your purchases by ordering completely filled packages. Moreover the purchase of multipacks offers you the benefit of a time-saving control at the intake of goods and facilitates handling them.

A detailed information about multipacks, if available, is given in all our sales documents.
