Light-sensitive substances require protection against light and particularly against the effects of UV light to extend their durability.

VITLAB^® has therefore developed special pigmented plastic products that are opaque and can protect a sample against light. The protection is equivalent to a sun protection factor of almost 20. Therefore, in the UV range from 280 nm and the upper visible range from 580 nm, the reagent bottles and volumetric flasks VITLAB^® opaque now even clearly surpass highgrade brown glass vessels.

Every single volumetric flask offers the accustomed VITLAB^® Class A accuracy in accordance with DIN EN ISO 1042 and has been individually calibrated to contain (` In`) at a reference temperature of 20°C.

Given the thickness of their wall, reagent bottles are highly resistant to the media they contain.

The superior level of break resistance and the lightweight material make VITLAB^® opaque an attractive alternative to conventional glass vessels when working in laboratories.
