Biosafety and steam sterilisation equipment
Biosafety cabinets and autoclaves support different parts of a laboratory's controlled working arrangements. A cabinet specification begins with the assessed work and containment requirement, while a steam steriliser begins with intended loads and process needs. They should be considered alongside the facility services and acceptance work they require. Neither equipment type should be purchased from a generic safety-equipment description alone.

- Usable workspace or chamber geometry
- Documentation, site testing and qualification requirements
- Required accessories, installation and operator instruction
Keep the two equipment purposes clear
A biosafety cabinet provides a specified work enclosure, while an autoclave processes defined loads using supported programmes. The laboratory's qualified team should establish the equipment requirements. Procurement can then request a model and configuration that meet that specification without inventing a containment or sterilisation method.
Resolve cabinet type and exhaust
For a Class II cabinet, identify the required type and the facility's air-handling arrangement. A clean bench and a chemical fume cupboard are different product types. Ask for installation and exhaust requirements for the exact cabinet, including the site testing the laboratory requires.
Describe autoclave loads in practical terms
List materials, container dimensions and batch quantities. Chamber volume does not establish usable geometry or suitability for every load. Ask the offer to identify baskets, relevant cycle functions and any options needed for the laboratory's intended processing tasks.
Assess services and access together
Request power, water, drainage, steam or exhaust information as applicable. Check how the equipment will enter the building and be maintained in its final position. Facility work can be a separate requirement and should not be assumed to be included in an instrument price.
Make acceptance responsibilities explicit
Identify manuals, product documents, on-site checks, qualification and familiarisation required by the laboratory. Ask who provides each item and what recurring service arrangements are proposed. A catalogue listing is a starting point for a defined equipment enquiry, not proof that the installed system has been accepted.
Common questions
Can a cabinet be selected from the disease area alone?
No. The laboratory's risk assessment and intended work should define the required containment arrangement, with facility requirements checked by qualified personnel.
Does every Class II cabinet need the same exhaust connection?
No. Cabinet type and model matter. Request the manufacturer's installation requirements for the exact proposed configuration.
Can an autoclave be chosen by litres alone?
No. The intended load, usable chamber dimensions and service requirements also need assessment.
Are on-site certification and qualification part of delivery?
Only where explicitly included. List the work and documents required and ask the offer to state responsibility for each.
