Start with the task, not a shopping list
Describe the apparatus, the substances it handles and the way people will use it. Include setup, sampling, cleaning and removal, because those stages can need different access or services from the main procedure. Review the fume hood air path when positioning fittings and apparatus.
Bring these details into our guide on how to choose a fume hood. The cupboard, its accessories and the extraction system should be discussed against one process brief, so an added fitting solves a real need.
For an existing cupboard, record the exact model and the current arrangement. Keep proposed changes separate from existing features so the supplier can see what needs assessment.
Create a schedule the project team can use
For each item, record the required function, the apparatus it serves and the person responsible for confirming it. Mark decisions that are still open and give them an owner before comparing quotations.
| Item | Information to gather | Decision to agree |
|---|---|---|
| Work surface | Chemicals, cleaning method, apparatus load and any penetrations | Compatible surface, support and layout |
| Water or gas service | Process need, service specification and control location | Supply boundary and connection responsibility |
| Electrical equipment | Equipment list, nameplate requirements and operating position | Suitable supply, access and installation scope |
| Support or base | Cupboard dimensions, load and access requirements | Supporting arrangement and usable working height |
| Controls and indication | Cupboard model and the operator information required | Model-compatible controls and handover instructions |
Check the layout before ordering
Draw the apparatus in its working position, with room to load and remove it. Show service leads, hoses and controls, including where the operator’s hands need to reach. Keep the cupboard’s intended air paths part of the layout review.
Our dimensions guide helps distinguish outer size from usable space. If a support or base also contains chemical storage, review the cabinet ventilation requirements separately with the project team.
Ask the supplier to confirm the proposed configuration against the exact cupboard model. Different fittings can require different mounting, service or access arrangements.
Make the quotation boundaries explicit
Identify what comes with the cupboard, what is optional and what another contractor will provide. For connected services, agree where each supplier’s work ends and who coordinates the final connection and checks.
A useful request might say: “We need water for this procedure, power for these two instruments and access to remove this vessel. Please confirm the proposed fitting positions and the work included in your scope.” Add the actual specifications and a layout sketch rather than selecting an item by appearance alone.
Use the budgeting guide to compare the complete scope. Keep the agreed accessory schedule with the final drawings and handover record so future service teams know what was installed.
