Light-sensitive substances require protection against light and particularly the effects of UV light to ensure that they can be used for a long time. VITLAB has therefore developed a special pigmented PMP plastic volumetric flask that is 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 VITLAB® opaque volumetric flask now even clearly surpasses high-grade brown glass volumetric flasks.
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. The superior level of break resistance and the lightweight material make the VITLAB® opaque volumetric flask an attractive alternative to conventional glass volumetric flasks when working in laboratories.
