Knittel microscope coverglass (coverslips) are made of a colourless borosilicate glass (D 263) with an optimum hydrolytic resistance HGB1. This ultra- thin glass is produced solely by only two special glass companies world-wide and by patented down-draw technology, working with very expensive platinum orifices for getting blister- and striae-free glass.

G405-15  Coverglass, circular, 18mm diameter, #1.5 thickness, box/100

G420-15  Coverglass, circular, 15mm diameter, #1.5 thickness, box/100

The "ultra-thin glass foils" are steadily controlled by the Quality Control Systems of our supplier in terms of the chemical composition as well as glass thickness and waviness. Through consistent developments and automatisation of the process- and cutting-technology, optimum dimensional accuracy has been reached. 

Our coverglass is manufactured in accordance to the international standard ISO 8255/1 and is ready to use. In order to prevent sticking, caused by stacking flat coverglass, we use very fine glass particles to powder the surfaces.
