400-Capacity Embedding Cassette Drawers with ID Labels — Polystyrene, Green, 2/Bag (258-4200-G10)
These green polystyrene cassette drawers hold up to 400 tissue and biopsy cassettes each, providing organized staging, storage, and transport at every stage of the histopathology workflow — from grossing room receipt through post-processing storage and embedded block archiving. Each drawer features an integrated front-panel ID label surface for handwritten or barcode accession batch identification, and the distinctive green color supports specimen-type color-coding programs across multi-category pathology labs. Supplied non-sterile in a bag of two, part number 258-4200-G10 is a Made in USA product from Caplugs® Evergreen.

Applications
- Pre-embedding cassette staging: Organize up to 400 cassettes ahead of the embedding station; the numbered ID label panel supports individual cassette location tracking within the drawer.
- Post-processing storage: Store wax-infiltrated cassettes after tissue processing; stackable drawers maximize benchtop and cold-room storage density while keeping batches segregated.
- Grossing room receive-and-sort: Use green drawers to designate a specific specimen type (e.g., GI or urology biopsies) or shift batch, reducing mis-routing in high-volume grossing rooms.
- Embedded block archiving: Protect processed paraffin blocks from dust and physical damage during long-term storage in cassette archive cabinets.
- LIS batch tracking: The front-panel label surface accommodates adhesive barcode labels for accession batch, date, or specimen-type IDs, enabling drawer-level tracking without per-cassette external labeling at the staging stage.

Frequently Asked Questions
How many cassettes does each drawer hold?
Each drawer holds up to 400 standard tissue and biopsy cassettes. Each bag contains two drawers, giving a combined capacity of 800 cassettes per bag.
Can these drawers be autoclaved between uses?
Yes — the polystyrene construction is compatible with standard gravity or pre-vacuum autoclave cycles at 121 °C / 15 psi for decontamination purposes between specimen batches or shift changes.
What is the ID label panel used for?
The integrated front-panel label surface accepts handwritten entries or adhesive barcode labels, so labs can record accession batch numbers, specimen types, collection dates, or shift assignments directly on the drawer — supporting LIS-linked drawer-level tracking without labeling each cassette externally at the staging stage.
Why green? Are other colors available?
Green provides strong visual contrast on grossing benches and is commonly used to designate specific specimen categories (such as GI or urology biopsies) in color-coded pathology workflows. A blue 400-capacity drawer is also available from LabSupplies.com, enabling multi-color systems from a single authorized dealer.
