Safety / overpressure valves, with spring loaded spherical ground joint seal, with stopcock
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. With standard stopcock, bore 3 mm.
Gas washing bottle reservoirs, Drechsel, borosilicate glass 3.3
In accordance with Drechsel. Ground joint 29/32. DIN 12463. Flask height 200 mm, working height 250 mm.

Gas washing bottles Duran®, acc. to Drechsel
With screw-connection system. The insertion height of the head is adjustable.Porosity 1Autoclavable
Gas washing bottle, PP
Graduated 250ml polypropylene cylinder with a stable extended base for use in precipitating elements from gas.Gas is dispersed through a removable fitting that has a coarse grade porosity, polyethylene dispersion discSilicone stopper holds 6.3mm O.D. tubes for entrance and exit of gas0.5 psi maximum pressure
Gas washing bottles, FEP/PTFE
PTFE top with two threaded connections. The standard PTFE frit has a pore size of approx. 3 µm and is screwed on the riser tube with an M8x1 thread. It can be exchanged with the PTFE gas distributor with fine bores which needs a lower primary pressure.Temperature resistance: from -200°C to 250°CTransparentUnbreakableFrit easily exchangeable

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.
Gas wash bottle reservoirs, Drechsel, borosilicate glass 3.3
According to DIN 12596. Bottle heads are supplied with or without sintered glass support (of porosity 0) which enables efficient gas dispensing. Bottle and selected head should be ordered seperately.
Bubble counter, DURAN®
DURAN® borosilicate glass. Modified, with NS 14.5/23 cone for direct mounting onto apparatus assemblies, screw neck and cap for filling with oil and tubing connector.
