Technical Narrative

The Caplugs® Evergreen 222-8021-01T is a 40 mL Sterile PS Inoculation Tray, 10/Box. Inoculation trays are shallow, flat-bottomed PS trays used in microbiology for sample spreading, streak plate inoculation, and sample distribution workflows where a contained flat surface is needed for specimen processing. PS construction provides the optical clarity to monitor inoculum distribution across the tray surface, and the sterile specification ensures the tray is contamination-free at the point of inoculation.

Polystyrene (PS): flat, rigid, optically clear tray surface; sterile single-use. BPA-free, phthalate-free, FDA-compliant,

Procurement economics: $54.28/Box (10 trays), $5.4275/tray. LabSupplies.com ships from USA inventory, typically same business day.

Clinical & Research Laboratory Applications

Caplugs® Evergreen 40 mL sterile PS inoculation trays serve clinical microbiology, research, and educational laboratories requiring a sterile shallow tray for sample spreading, inoculum staging, and reagent preparation at the bench. In clinical microbiology BSCs, inoculation trays provide a contained sterile working surface for swab unpackaging, specimen spreading before loop transfer to agar plates, and serial dilution staging for quantitative cultures. In molecular biology workflows, the sterile 40 mL PS tray serves as a reagent pool vessel for multi-channel pipetting during microplate assay setup — the flat tray bottom allows complete reagent recovery with a multi-channel pipette tip row. Single-use sterile format eliminates cross-contamination risks between specimens or reagent lots.

Frequently Asked Questions

Are the inoculation trays sterile?

Yes. Sterile — packed 10/Box.

What is the 40 mL inoculation tray used for?

The 40 mL sterile PS inoculation tray is a shallow flat tray used in microbiology for sample spreading before agar plate inoculation, reagent staging for multi-channel pipetting, serial dilution setup, and swab processing. The flat PS surface provides an optically clear, sterile working area for these preparation steps.

Can the inoculation tray be used as a reagent reservoir for multi-channel pipetting?

Yes. The 40 mL PS tray is compatible with use as a reagent reservoir for multi-channel pipette loading in 96-well plate assay setup. The flat tray bottom allows complete reagent recovery with a standard 8- or 12-channel pipette tip row. Use sterile reagents and maintain the tray in a BSC if sterility is required.
