Pigmented Plastic Volumetric Flasks - Greater protection for light-sensitive substances
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 now developed and manufactured the world's first 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 high-contrast ring-mark ensures an accurate reading of the meniscus. 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. VITLAB® opaque volumetric flasks with PP screw caps are available in all sizes from 10 to 1000 mL.
