DURAN® Dropping Funnel, cylindrical, ground joint and pressure equalisation tube

DURAN® Dropping Funnel, cylindrical, with scale and ground joint, with pressure equalisation tube, NS 14/23, 100 mLThe dosed addition of solutions, reaction mixtures and/or chemicals is ideally carried out using a dropping funnel. In addition to the standard ground joint, this design contains a pressure equalization tube at the lower end, which avoids both negative and positive pressure in the reaction vessels.Features and Benefits:Complies with DIN ISO 4800With pressure equalisation tube, standard ground cone, standard ground stopcock and retaining deviceThe rate of supply can be adjustedCylindrical with scaleTight closure due to standard ground jointFired-on, highly durable white printEasy-to-read scale with graduation marks to estimate the contentApplication: Uniform and metered liquid supply to a reaction mixture, Measuring liquid amounts, Dropping funnels with a volume of 250 ml (with socket: 29/32, cone: 24/29) and 500 ml (with socket: 29/32, cone: 24/29) are special sizes and not according to DIN ISO. more
