Brandtech Announces New VITLAB® Light-Shielding Volumetric Flasks
3 Oct 2010VITLAB® light-shielding volumetric flasks from BrandTech Scientific provide light protection superior to amber glass. They are made of a specially pigmented polymethyl pentene (PMP) plastic that provides excellent absorption of light.
VITLAB® flasks have absorption in the UV range – below 280nm and the upper visible range above 580nm— but provide sufficient translucency to verify contents and volume, in most applications superior to amber glass. They also provide a sunlight protection factor of nearly 20. Flasks are light weight and break resistant, and provide a cost-effective alternative to glass. Screw-on caps help protect flask contents better than traditional stoppers.
Flasks are available in sizes from 10mL to 1000mL. All volumes are Class A per DIN EN ISO 1042.

VITLAB Class A Volumetric Flasks with Screw Cap, Light-Shielding PMP
BRANDTECH® Scientific, Inc.VITLAB® Light-Shielding Class A PMP Volumetric Flasks With Screw Cap VITLAB® tinted polymethylpentene volumetric flasks offer superior opacity to ultraviolet light, as well as much of the visible spectrum, compared with amber glass. They are also light weight and offer superior break resistance. An excellent choice for measurement of light-sensitive materials. Flasks are available in sizes from 10mL to 1000mL and are supplied with tinted PP screw caps. They offer accuracy to Class A standards per DIN EN ISO 1042, even after autoclaving at temperatures up to 121ºC. Flasks may also be sterilized with formalin or ethanol, or by ß-radiation, and are microwaveable. Excellent resistance to acids, alkalis and alcohols at room temperature, and good to limited (short term exposure) resistance to aliphatic hydrocarbons, aldehydes, ketones and esters. They are not suitable for use with aromatic or halogenated hydrocarbons, ethers, oxidizing acids or oxidizing reagents. Each flask is individually calibrated to-contain ('In') at a reference temperature of 20ºC, individually ring-marked, for accuracy, imprinted with a lot-number, and shipped with a lot certificate. The high contrast ring-mark ensures an accurate reading of the meniscus.
