40 mL Trays, PS, Natural — 222-8122-01T | 10/Box | Caplugs® Evergreen

40 mL Two-Split Inoculation Trays — Polystyrene, Sterile, Natural, 10/Box (222-8122-01T)

These 40 mL two-split inoculation trays are molded from natural (clear/translucent) polystyrene and supplied sterile, 10 trays per box, for microbiological and cell culture workflows requiring divided compartments. The two-split format partitions the tray into two discrete sections, allowing separate samples or reagents to be handled within a single footprint while maintaining sterile conditions out of the box. Part number 222-8122-01T is well suited for labs that need ready-to-use sterile trays without additional processing steps.

Technical Specifications

Applications

• Inoculation and streaking of microbial cultures requiring separated sample zones
• Side-by-side comparison of reagents, media, or specimen preparations within a single tray
• Sterile liquid handling and dispensing in clinical microbiology and research settings
• Serial dilution setups where compartment separation reduces cross-contamination risk
• General microbiological workflows that benefit from a pre-divided, ready-to-use sterile format

Material & Chemical Resistance

Polystyrene provides clarity and rigidity that allow easy visual monitoring of contents within each compartment, making it well suited for aqueous samples, standard biological media, and dilute buffers. As with all PS labware, avoid acetone, alcohols above 70%, and aromatic or chlorinated solvents, which can craze or dissolve the material; polystyrene is not autoclavable, so these trays should not be re-sterilized by heat or steam.

Quality & Procurement

Made in USA, Caplugs® Evergreen inoculation trays are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin and are supplied sterile for immediate use. LabSupplies.com is an authorized dealer and ships from USA inventory, typically same business day for stocking items, with tiered pricing available for institutional and high-volume laboratory accounts.

Frequently Asked Questions

Are these inoculation trays truly sterile as supplied?
Yes — the trays are supplied sterile out of the box, ready for direct use in microbiological and cell culture procedures without any additional sterilization step.

What does the two-split format mean in practice?
The tray is divided into two discrete compartments within the same unit, allowing two separate samples, media, or reagents to be handled side by side while remaining physically isolated from each other.

Can these trays be autoclaved for re-use?
No. Polystyrene is not compatible with autoclave temperatures or steam sterilization and will deform under those conditions. The trays are intended for single-use sterile applications.
