Analytical Gas Installations

If you have had your laboratory recently fitted out with new gas lines recently, they will probably look very professional and comply Pressure System Safety Regulations 2000 or with the Health & Safety at Work Act 1974 and with best practices from the British Compressed Gas Association (BCGA). You may have made the decision to use gas generators which have in-built safety features. If this is not the case and you may need to have your installation inspected.

The installation may terminate with one regulator or isolation valve for each gas. This may not be a problem however if you have more than one instrument or the number of instruments expand you will require separate isolation valves for each instrument. This setup enables you to keep instruments running, while maintaining or decommissioning older instruments.

Typical GC Gas Installation

Also, more often than not valves and fittings to the instrument may not look so neat and tidy and could be intertwined 1/8” copper tubing. Critically this may not easily identifiable if you need to isolate, leak check, or reconfigure the gases, particularly if you have restricted access around the back of the instrument.

Therefore, to make the identification easier ChromSolutions have developed a series of low costs products to identify valves, gas lines and sample cylinders. We have some standard 3D printing products; however, we can easily customise to gas type, valve and tag sizes to your specific requirements.

Gas Line/Sample Cylinder Tags

Also printed in PLA are the gas line tags. Again they are colour coded according to BCGA – Technical information sheet 6 : Gas cylinder identification label and colour code requirements. They will also display the gas type by its chemical symbol and can be mounted vertically or horizontally:

The tags provide a convenient way to easily identify the contents of gas lines. The tags are available for all commonly used laboratory gases.

• Part Number: CS-GT-***-3D (replace *** with gas type i.e. He – Helium, O₂ – Oxygen etc)
• Product: Gas Tag
• Diameter (mm): 60
• Height (mm): 3
• Weight (g): 6

Gas Isolator Valve Box

3D printed in PLA the boxes allow mounting of an isolator valve. The box and lids are colour coded according to BCGA – Technical information sheet 6 : Gas cylinder identification label and colour code requirements. They will also display the gas type by its chemical symbol and show the on/off status of the valve. The boxes are available for all commonly used laboratory gases and can be mounted either in a vertical or horizontal orientation.

ChromSolutions: 2 Way Valve Boxes.

The boxes can be mounted either with double sided tape or screws, as single gases or as multiple boxes on a back plate. Both the individual and the single boxes can be mounted to walls or bench tops. The boxes provide a convenient way to mount an isolator valve that allows easy access and identification of the gas that the valve isolates.
