Distributors

BOLA Multiple Distributors for Bottles

How can liquids be taken out of a bottle or reaction vessel and simultaneously be distributed to several recipients without spillage? How can I pour different liquids into my vessel without loss? These questions were the beginning of BOLA Multiple Distributors for Bottles.
They consist of a screw cap with GL threadGlossaryGL threadGlass thread and a movable body with GLthreaded necks. These necks allow the connection and insertion of hardwalled tubing (e.g. PTFEGlossaryPTFEPolytetrafluoroethylene , PFAGlossaryPFA Perfluoroalkoxy , FEPGlossaryFEPTetraflouroethylene-Perflouropropylene) or tubes made of different materials (glass, metal, plastic) by means of BOLA Laboratory Screw Joints.

The distributors are not only the basis of a distribution system which can be operated under pressure and vacuum. It is also possible to insert probes or electrodes into the GL-threaded necks and to fix them by means of laboratory screw joints. A possible unevenness of the bottle neck is adjusted by an o-ring behind an elastic sealing lip, and the bottle is closed tightly. The product is only exposed to the body of the distributor. The special feature: the body of the distributor can be turned independently from the screw cap. This means, that the completely assembled distributor can be removed and fixed on another bottle without the risk of disarranging the tubing.

BOLA Flexible Distributors

BOLA Flexible Distributors have been developed especially for the connection of elastic tubing. They consist of a screw cap with GL threadGlossaryGL threadGlass thread and a movable body with hose connectors for attaching tubing. Hose connectors on the lower side also allow a connection of tubing to reach the bottom of the bottle.

The flexible distributors are the basis of a distribution system and can also be operated under pressure and vacuum. The bent hose connectors prevent bends in the tubing. A possible unevenness of the bottle neck is adjusted by an o-ring behind an elastic sealing lip, and the bottle is closed tightly. The product is only exposed to the body of the distributor. The special clou: the body of the distributor can be turned independently from the screw cap. This means, that the completely assembled distributor can be removed and fixed on another bottle without the risk of disarranging the tubing.

BOLA Distributors for Reaction Vessels

Suitable for bottles with GLS 80 thread from Duran Group (formerly Schott AG).

Consisting of a screw cap with GLS 80 thread and a movable body with several lateral necks and one central neck.

The GL-threaded necks allow the connection of hard-walled tubing (PTFEGlossaryPTFEPolytetrafluoroethylene , PFAGlossaryPFA Perfluoroalkoxy , FEPGlossaryFEPTetraflouroethylene-Perflouropropylene) or tubes (glass, metal, plastic) by means of BOLA Laboratory Screw Joints. It is also possible to insert and fix probes or electrodes. In addition, the connection of elastic tubing can be made by means of BOLA Hose Connectors.

The type “Center Neck with Ground Joint” allows the use of a stirrer bearing which assures a centrical position of a stirrer shaft in the vessel. Other components with ground joint (e.g. condensers, funnels etc.) can also be connected easily.

The type “Center Neck with GL Thread” is supplied with an exchangeable stirrer bearing for the center neck.

A possible unevenness of the bottle neck is adjusted by an o-ring behind an elastic sealing lip, and the bottle is closed tightly. The product is only exposed to the body of the distributor. The special clou: the body of the distributor can be turned independently from the screw cap. This means, that the completely assembled distributor can be removed and fixed on another bottle without the risk of disarranging the tubing.

BOLA Distributors for Canisters

These distributors are ideal for drawing liquids from canisters and for distributing these liquids to several vessels.

They consist of a screw cap for canister threads S 55 or S 60 and a movable body with three GL-threaded necks. The threaded necks allow the connection of tubing or tubes made of glass, metal, or plastic by means of BOLA Laboratory Screw Joints. The distributor can also be integrated into a pressure or vacuum system.

A possible unevenness of the canister thread is adjusted by an o-ring behind an elastic sealing lip, and the canister is closed tightly. The product is only exposed to the body of the distributor.

A special clou: the body of the distributor can be turned independently from the scew cap. This means, that the completely assambled distributor can be removed and fixed on another canister without the risk of disarranging the tubing.

BOLA Swivelling Screw Fittings

BOLA Swivelling Screw Fittings for GL threads or ground joints are ideal for fixing all kinds of probes, tubes or hard-walled tubing safely in a specific angle. It is possible to position supply tubes or probes independently from the angle of the neck.

Damages of supply tubes or probes due to collision with the stirrer shaft can be avoided.

BOLA Multiple Distributors for Barrels

These distributors are ideal for drawing liquids from barrels and for distributing these liquids to several vessels. They consist of a screw cap for barrels with female thread and a movable body with GL-threaded necks. The threaded necks allow the connection of tubing or tubes made of glass, metal, or plastic by means of BOLA Laboratory Screw Joints. Liquids can be drawn from the barrel without contamination of the ambient air by leaking vapours. In addition, the distributor can be integrated in a pressure or vacuum system.

The special clou: the body of the distributor can be turned independently from the screw cap. This means, that the completely assembled distributor can be removed and fixed on another barrel without the risk of disarranging the tubing.
