Cover glasses

We deliver cover glasses for microscopy in all available sizes, thicknesses and in excellent quality and dimensional accuracy

Glass quality

In our fabrication of cover glasses only glass quality of the hydrolytic class I is used. The hydrolytic class, also called hydrolytic resistance, defines the rate of extractability of alkaline compounds from glass after attack of water at 98 °C. The hydrolytic classes are the base in classification of glass types for pharmaceutical use in the European Pharmacopoeia.[1][2]

O. Kindler Eukitt Cover Glasses

Class I also referred as neutral glass covers the group of boron silicon glasses (e.g. Duran®, Pyrex®, Fiolax®, etc.) and contain substantial amounts of boron-, aluminum- or alkaline earth oxides. Because of its ingredients neutral glasses owns high resistance against thermal shock and hydrolysis. Additionally those glasses are characterized by high chemical resistance related to acid and neutral solutions and because of the low alkaline content for alkali too. [1]

Our cover glasses are free of blisters and flowmarks. They have an ideal planar surface and therefore clear and undistorted images even into the peripherical areas of the field of vision are accessible. Our products are storable for many years without any quality losses.

Our glasses are ready to use and can be used immediately.
