REAGENT & CENTRIFUGE TUBES

We manufacture reagent and centrifuge tubes in standard sizes and also with special dimensions and versions from soda glass, borosilicate glass, neutral glass, and quartz glass – optionally with or without flanged rim. All our tubes have a flame burnished rim and can be supplied with a rounded, flat or pointed conical bottom. We are able to process tubes with diameters up to 40 mm, and lengths up to about 500 mm – also thick-walled tubes.

Special reagent micro tubes

We are able to manufacture reagent micro tubes with rounded bottoms, i.e. with very small dimensions. For example, soda glass tubes with rounded bottom, flame burnished rim, 3 mm diameter, and a length of 20 mm.

Test tubes with notch for thermal processes

These special test tubes were developed to enable ventilation of the tube’s interior during a thermal process. The notch prevents complete closure and thus an over pressure.
