Product Description
Uncapped solvent reservoirs leak vapors into the lab and pick up dust that can compromise a separation. These replacement HPLC caps and parts keep mobile phases enclosed, improve safety and help protect the quality of your chromatography.
This listing is for DURAN catalog number 1129813: Replacement Parts Set for GL 45 HPLC Screw Cap, includes 4x M8 caps and 12x silicone tubing seals (1.6 or 3.2 mm) or closure seals. The assembled GL 45 polypropylene cap provides four ports with black M8 screw connections and silicone seals sized for 1.6 or 3.2 mm tubing, plus blanking seals for unused ports. A spare parts set restocks the M8 caps and seals, and a pressure equalization set with a 0.2 micron syringe filter allows sterile venting as liquid is drawn off. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
Key Features
- Four tubing ports – Supports multiple solvent lines from one reservoir.
- Two tubing sizes – Silicone seals fit 1.6 or 3.2 mm OD HPLC tubing.
- Blanking seals – Close off unused ports to block solvent vapors.
- Sterile venting option – Pressure equalization set uses a 0.2 micron syringe filter.
