BURETTE W/PTFE KEY STCK CLASS A 10ML

Details

Here is the corrected text: VWR Burets are made from Borosilicate 3.3 glass, conforming to ASTM 438 Type 1, Class A standard. The graduations are typically calibrated "to deliver" (marked "TD" or "EX") at 20 to 27 °C and indicated correspondingly on a label. These serialized, individually certified products are designed to deliver a precise volume at a particular temperature. Supplied with a chemically resistant, self-lubricating PTFE stopcock plug, they are used primarily for titration, delivering one reactant until the precise endpoint is reached. Calibration and tolerances conform to ASTM E287, ASTM E542, ASTM E694, and ISO 385 standards. Available in various capacities: * 100 ml: Cat.
