VITLAB® Light-Shielding Volumetric Flask with Screw Cap, Class A
By Brandtech
Tinted volumetric flasks of polymethylpentene (PMP) 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 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 121°C. Flasks may also be sterilized with formalin or ethanol, or by β-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 20°C, 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
