Description
The DURAN® Woulff bottle NS 29/32 with 2000 mL nominal volume is a robust borosilicate glass 3.3 vessel engineered for vacuum apparatus. It serves as a collection vessel during gas generation or for cleaning and drying gases, and is frequently employed as an intermediate vessel to prevent sudden vacuum loss and liquid suck-back into the pump. Three standard ground joints enable controlled gas inlet or outlet, while the wall thickness and geometry ensure vacuum resistance and a tight seal via the ground joint. A permanently fired white print provides durable labelling. Typical applications include collecting and dissolving gases in liquids, gas preparation, safe vacuum work and series connection for gas purification. Manufactured by Duran/DWK Life Sciences, this single-piece bottle offers high user safety under pressure and vacuum conditions and is supplied ready for laboratory integration.
