b.safe caps together with fittings, tubing and an air valve form a perfect unit for solvent extraction from laboratory flasks.

• Perfect protection from hazardous vapours
• Closed system: reduction of expensive solvent loss
• Guarantee of pure eluents
• Huge choice of cap sizes for compatibility with any eluent flask
• No twisting of capillaries
• Screw caps can individually be labelled by hand or with removable, self-adhesive labels

b.safe air valve: The special valve lets flow into the bottle as much ambient air as necessary for pressure compensation during solvent extraction. An integrated PTFE membrane (pore size 1 µm) restrains pollutant particles from the bottle content. The included colour-changing indicator helps to monitor the service life for an on-time exchange after six months. Additionally, the installation date can be documented on the back side.

b.safe fittings: Optimised surface for best grip even with gloved hands. Cantering pin for easy installation in b.safe caps.

b.safe blind fittings: For closing unused ports on the cap.

b.safe caps: Robust screw cap with ergonomic design for easy installation and individual marking by hand or with exchangeable, self-adhesive labels. PTFE-insert for excellent chemical resistance. Inclined connection threads on the cap guarantee intuitive insertion of fittings and air valve, tubes can be inserted safely into the bottle and fixed in any height without being bent.
