b.safe Waste Caps with Filling Funnel with Filling Funnel
b.safe Waste Caps with Filling Funnel are the best choice for the collection of HPLC solvent waste. The freely turnable PTFE insert is equipped with the standard thread connectors UNF 1/4“ and NPT 1/8” for connecting different tubing diameters by means of Fittings or Hose Connectors. The HPLC waste can be lead directly into a collection container.
Also liquid waste as e. g. produced for the preparation of samples can be directly filled into a collection container by using the permanently fixed Filling Funnel. The integrated stopcock reliably blocks the passage as protection against escaping vapours.
Choose one of the offered Filling Funnel designs: Version “Stopcock with grip” where the passage opens by turning the grip and the grip position indicates if the stopcock is closed. The funnel of this version is generously measured for a good liquid drain. The sieve can be removed. In the version “Automatic Stopcock”, the passage is opened by pushing the grip. As long as the grip is pushed, the passage remains open. As soon as the grip is loosened, the passage is closed automatically. The integrated sieve cannot be removed. The connector GL14 is reserved for the separately available Exhaust Filter. Its activated carbon filling adsorbs solvent vapours which are produced during filling so that no harmful vapours can escape from the collection container.
A Viton® flat sealing provides tight closure of the collection container as it compensates possible production tolerances on the threaded neck. A special sealing lip made of PTFE isolates it from the vapour space. Combined with an Exhaust Filter, b.safe Waste Caps are the perfect protection for the disposal of solvent waste.
