Corning 5640P-10 Class A Reusable Volumetric Flask with 10/19 Ta
This fits your .
Translucent flask is supplied with tapered polypropylene stopper with an individually calibrated graduation line. The product is manufactured to Class a tolerances as defined by ISO 1042. They are supplied with an imprinted lot number and certificate. These flasks may be autoclaved to 121 degree C without affecting the graduation tolerance. Recommended routine cleaning up to 60 degree C will preserve graduation markings. Height dimension is for flask only, without stopper. The accuracy of volumetric ware depends on the care used in calibrating it, using the correct Type of ware for the application, handling the ware properly and ensuring the ware is clean. Calibration of volumetric ware is usually done at 20 degree C, and the ware should be used at approximately this temperature. Refrigerated liquids should be allowed to come to room temperature before measuring them. Under normal use and care, the calibration of volumetric ware will not change. Do not expose volumetric ware to excessive heat, defined as temperatures approaching the corning-defined upper service limit.
