Vacuum Cylinder Chambers

Glass cylinder systems offer the user access through the top of the cylinder. This provides a very versatile system for all round visibility and access to the chamber without the removal of a bell jar.

The Glass cylinder systems have the same specification as the standard Bell Jar Systems SF and VF range, but with the addition of an extra ‘L’ gasket and an acrylic lid. There is an option to have an aluminium lid if you require vacuum levels less then 1 x 10^-2 mbar, when the outgassing rate of acrylic becomes an issue.

VF – CYLINDER VACUUM SYSTEM – MODEL VC-12-VF

The model VC-12-VF will comprise:

A borosilicate glass bell jar measuring 315mm OD x 301mm ID x 356mm H, fire polished and ground on the open end and fully annealed after manufacture, suitable for many vacuum applications. The seal will be  Nitrile rubber ‘L’ gaskets. (Viton rubber seals available as an option).

The base plate will be machined from 304 Stainless Steel mounted on three legs with feet suitable for standing/securing to the bench. The pumping port will be offset from the centre. The base plate is fitted with two service ports as standard. The first port is NW25 and is fitted with an ‘O’ ring, blank plate and clamp. The second port is 3/8” BSP and is fitted with a blanking plug.  All ports are positioned 120° apart on the same PCD.

The lid is manufactured from clear cast acrylic and is fitted with a lifting handle.

A vacuum manifold will be fitted comprising an Edwards NW16 pump isolation valve, an Edwards AV10K NW10 system vent valve and a 63mm diameter glycerine filled vacuum gauge scaled 0-1000Mbar together with all the necessary NW fittings to form a complete vacuum system. The manifold will terminate in a rifled nozzle.

The system is suitable for use at pressures down to 
1 x 10־³Mbar.

After manufacture the system is leak mass spectrometer tested and subjected to a pressure rise test.

SF – CYLINDER VACUUM SYSTEM – MODEL VC-12-SF

The model VC-12-SF will comprise:

A borosilicate glass cylinder measuring 315mm OD x 301mm ID x 356mm H, fire polished and ground on the open end and fully annealed after manufacture, suitable for many vacuum applications. The seal will be a Nitrile rubber ‘L’ gaskets. (Viton rubber seals available as an option).

The base plate will be machined from 304 Stainless Steel mounted on three legs with feet suitable for standing/securing to the bench. The pumping port will be offset from the centre. The base plate will include two service ports as standard. One NW25 and one NW16. Both will be fitted with an ‘O’ ring, blank plate and clamp.  All ports are positioned 120° apart on the same 260mm  PCD

The lid is manufactured from clear cast acrylic and is fitted with a lifting handle.

A vacuum manifold will be fitted comprising a stainless steel isolation valve, a stainless steel system vent valve and a 63mm diameter glycerine filled vacuum gauge scaled 0-1000Mbar together with all the necessary Stainless Steel screwed fittings. The manifold will terminate in a riffled nozzle to accept a flexible 12mm ID vacuum hose (not included)..

The system is suitable for use at pressures down to 
1 x 10־²Mbar.

After manufacture the system is leak mass spectrometer tested and subjected to a pressure rise test.

AC – CYLINDER VACUUM SYSTEM – MODEL VC-12-6-AC

The model VC-12-6-AC will comprise:

A borosilicate glass bell jar measuring 315mm OD x 301mm ID x 145-155mm H, fire polished and ground on the open end and fully annealed after manufacture, suitable for many vacuum applications. The seals will be  Nitrile rubber ‘L’ gaskets. 

The base is manufactured from clear cast acrylic and is fitted with rubber feet. 

The lid is manufactured from clear cast acrylic and is fitted with a lifting handle, vacuum isolation valve with hose nozzle, air admittance valve with restrictor valve and 63mm vacuum dial gauge.

The system is suitable for use at pressures down to 
1 x 10-1Mbar.
​
After manufacture the system is leak mass spectrometer tested and subjected to a pressure rise test.

Safety Warning: 

We strongly recommend that all our Vacuum Bell Jar Degassing Systems are fitted with an implosion guard during use. 

We can supply Acrylic transparent implosion guards to fit all of our Vacuum Bell Jar Systems.
