40 mL Sterile Inoculation Trays — Polystyrene, Natural, 10/Box (222-8021-01T)
These 40 mL shallow, flat-bottomed polystyrene inoculation trays from Caplugs® Evergreen are supplied sterile, 10 per box, for use across clinical microbiology, research, and educational laboratory settings. The rigid, optically clear PS construction lets technicians monitor inoculum distribution across the tray surface, while the sterile specification ensures a contamination-free working surface at the point of use. Part number 222-8021-01T is a single-use tray designed for sample spreading, streak plate inoculation, serial dilution staging, and reagent pooling workflows where a contained, sterile flat surface is essential.

Frequently Asked Questions
Are these inoculation trays sterile straight out of the box?
Yes — each tray is supplied sterile and ready to use at the point of inoculation, with no additional preparation required before opening the package in a clean or biosafety cabinet environment.
Can these trays be autoclaved for re-use?
No. Polystyrene cannot withstand autoclave temperatures and these trays are rated for single use only. The sterile supply format eliminates any need for re-sterilization.
What solvents should I avoid with these PS trays?
Avoid acetone, chloroform, and other chlorinated or aromatic solvents, which will dissolve polystyrene. Standard aqueous buffers, dilute acids and bases, cell culture media, and low concentrations of DMSO are all compatible.
How many trays come in a box, and what is the tray volume?
Each box contains 10 individually sterile trays, each with a 40 mL capacity — sufficient for sample spreading, serial dilution staging, and reagent pooling in a compact bench footprint.
