Extraction Lab Quote Checklist: What to Prepare Before You Buy

An extraction lab quote is only comparable when the process, site and scope are comparable. Before asking for pricing, document what will happen inside the enclosure, what equipment must fit, and which work belongs to the supplier versus your facility team.

What information belongs in an extraction lab quote request?

Start with a one-page project brief. State the project location, whether the building is existing or new, your intended process and the equipment you expect to operate. Describe extraction, material transfer, unloading, cleaning and any separate post-processing or off-gassing activity. A throughput target is useful, but it does not replace a process description.

List the solvents or gases involved and provide the relevant safety data sheets to your project professionals. Explain the routine operating sequence and known abnormal scenarios. OSHA's electrical rules require each room, section or area to be considered individually; an existing classified room elsewhere in the building does not automatically define the new project's requirements.

How should you document equipment and room dimensions?

Provide more than the footprint of the extraction machine. Include ancillary equipment, pumps, transfer carts, work surfaces and the largest item that must pass through each doorway. Mark service access and the space needed to remove components. Identify whether equipment dimensions include hoses, control cabinets, insulation and accessories, or only the main skid.

Ask whether the proposed room dimensions are exterior dimensions, nominal footprints or usable interior dimensions. Wall construction and internal systems can affect the clear space. Record ceiling height, overhead obstructions and access for assembly. If the room fits only when equipment is drawn without service space, the layout is not ready for a final comparison.

Which site conditions can change the enclosure scope?

Share what is known about electrical service, ventilation routes, makeup air, roof penetrations and access to the installation area. Flag landlord restrictions and limits on outside equipment. The supplier needs enough information to identify interfaces; your facility designers must still verify building systems and permitting requirements. An enclosure package does not remove those coordination tasks.

Photographs help explain existing conditions, but they are not a substitute for measured drawings. Label photos with their location and viewing direction. For a retrofit, show nearby production, occupied spaces and the intended path for equipment delivery. Discuss shutdown constraints early rather than discovering them after fabrication.

How do you compare two extraction lab proposals fairly?

Does a UL listing mean the whole facility is approved?

No. A listing addresses the equipment and configuration covered by the listing, not every condition at a particular building. UL's plant oil extraction guidance discusses extraction equipment and booths alongside relevant installation codes and manufacturer instructions. Ask for the actual listing scope rather than assuming that every accessory, modification or adjacent process is included.

Likewise, a peer review or enclosure drawing package should be understood by its written scope. Identify the local Authority Having Jurisdiction and the professionals responsible for facility design. Keep classification documentation and the approved equipment configuration available to the people who install, inspect, maintain and operate the system.

Which schedule and cost assumptions should be written down?

Separate engineering, submittal review, manufacturing, delivery, site preparation and commissioning milestones. Ask what starts each period: an initial inquiry, signed order, approved drawings, deposit or completed site conditions. Avoid comparing two promised dates that begin at different milestones.

Request a clear list of allowances and exclusions. Facility work, taxes, permits, unloading, electrical service upgrades and roof work may sit outside the enclosure package. Discuss how a changed equipment list or a plan-review comment will affect scope. This gives your team a more useful basis for a project budget than a single undifferentiated number.

What should happen after the first quote?

Resolve assumptions before converting the quote into a final design. Review the proposed layout with operators, maintenance staff and the facility design team. Ask the supplier to identify open decisions and required inputs. Keep a revision record so the selected enclosure, equipment layout and site work remain coordinated as the project develops.
