DURAN® Dropping Funnel, with ground joint and pressure equalisation tube, NS 24/29, 250 mL

cylindrical with scale and ground joint
  • Complies with DIN ISO 4800
  • With pressure equalisation tube, standard ground cone, standard ground stopcock and retaining device
  • The rate of supply can be adjusted
  • Cylindrical with scale
  • Tight closure due to standard ground joint
  • Fired-on, highly durable white print
  • Easy-to-read scale with graduation marks to estimate the content
Product Overview
The 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. The dropping funnel allows a dosed addition of solutions. Due to the pressure compensation tube a possible under- and overpressure is prevented.
