Safety / overpressure valves, with spring loaded spherical ground joint seal
When laboratory ground devices are used under vacuum or/and slight overpressure, the use of this combined overpressure safety valve can be recommended. These valves act as immediately closing safety valve under vacuum and they allow under overpressure the visual control of the bubble formation in the blocking liquid. The real sealing is effected by a special designed spherical ground joint (cup and ball) on which an adjustable spring power acts. It is supported by a free to chose blocking liquid which should be higher viscous for vacuum operations. The sealed climbing tube at the spherical ground cup serves as a guide and prevents that the liquid climbs back into the apparatus.

Screwthread tubes for glassblowers, DURAN® tubing
Acc. to DIN 12216 and in addition to standard, with DIN thread (GL).
Screwthread tubes with NS cone, DURAN® tubing, cap and sealing
Screw thread adapters , made of DURAN® tubing, with screw-cap with aperture and silicone sealing ring with PTFE washers.
Scrubber Adapter for Bottles, PTFE
Consisting of PTFE body with connecting nut and two lateral GL18 threaded necks, a 300mm long FEP inlet tube and a gas distributor with frit. Easy in- and outlet of gas by means of rigid-walled tubing (e.g. PTFE) which can be connected to the threaded necks using Bola Laboratory Screw Joints. Elastic tubing can be connected by means of hose connectors. Inlet tube can be individually shortened. Special feature: the body of the adapter can be turned independently from the connecting nut. This means, that the completely assembled adaptor can be removed and fixed onto another bottle without the risk of disarranging the tubing. Suitable for bottles with GL45 or GLS80 threads and capacities between 100ml and 5000ml.
Scrubber Bottles Vitrum, borosilicate glass/PTFE
Consisting of PTFE body with screw cap and two lateral GL 18 threaded necks, suitable borosilicate glass bottle as well as a FEP inlet tube and a gas distributor with finest bores. Easy inlet and outlet of gas by means of hard-walled tubing (e. g. PTFE) which can be connected to the threaded necks with BOLA Laboratory Screw Joints. Elastic tubing can be connected by means of hose connectors. The special feature - the body of the distributor can be turned independently from the screw cap, thus the completely assembled distributor can be removed and fixed onto another bottle without the risk of disarranging the tubing. Suitable for Vacuum.
