For this reason in 2008 VITLAB® developed and manufactured the world’s first special pigmented PMP plastic volumetric flask that is opaque and can protect a sample against light. In time for ACHEMA the product range has been extended to include opaque reagent bottles.

The protection of media in the opaque volumetric flasks and reagent bottles 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 and reagent bottles now clearly surpass high-grade 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. The high-contrast ring-mark ensures an accurate reading of the meniscus. Volumetric flasks VITLAB® opaque with screw cap are available from 10 to 1000 ml.

The opaque reagent bottles are especially thick-walled and are therefore highly resistant to the media they contain. The standard joint stoppers create a perfect closure. Reagent bottles VITLAB opaque are available from 500 to 2000 ml.

The superior level of break resistance and the lightweight material make VITLAB® opaque an attractive alternative to conventional volumetric flasks and reagent bottles made of glass when working in laboratories.

VITLAB® is one of the world’s leading manufacturers of liquid handling equipment and plastic laboratory products, and can look back on a more than 100-year company history. The company’s products are marketed by a worldwide network of distributors and are used in laboratories in wide-ranging application areas, including the measurement of volume, sample drawing and storage.
