400-Capacity Embedding Cassette Drawer with ID Labels — Polystyrene, Blue, 2/Bag (258-4202-B10)
These blue polystyrene cassette drawers hold up to 400 tissue and biopsy cassettes each, making them an efficient solution for pre-embedding staging, post-processing storage, and grossing room organization in histopathology workflows. Each drawer features an integrated front-panel ID label surface for handwritten or barcode identification of accession batches, shifts, or specimen types, and the pack of 2 per bag supports rapid multi-drawer deployment across a full pathology cassette pipeline. Supplied non-sterile, they are compatible with standard grossing bench shelving and cassette storage cabinet rails without auxiliary hardware.

Applications
- Pre-embedding cassette staging: organized holding of up to 400 cassettes ahead of the embedding station, with front-panel labeling for batch tracking
- Post-processing storage: housing wax-infiltrated cassettes after tissue processing while awaiting embedding, with stackable drawers maximizing bench and cold-room density
- Grossing room receive-and-sort workflows: color-coded blue drawers support specimen-type, day-of-week, or shift-based routing without per-cassette external labeling overhead
- Embedded paraffin block archiving: long-term drawer storage protects processed blocks from dust and physical damage in cassette archive cabinets
- LIS-integrated batch workflows: drawer-level barcode or handwritten ID labeling enables accession batch identification within laboratory information system tracking schemes

Frequently Asked Questions
Can these drawers be autoclaved for decontamination between uses?
Yes — the polystyrene construction is compatible with standard autoclave cycles at 121°C / 15 psi, making these drawers suitable for regulated pathology environments that require decontamination between accession batches or at shift changeover.
How are the ID labels used, and do they support barcode labeling?
Each drawer includes a front-panel label surface that accepts both handwritten notation and adhesive barcode labels, allowing laboratories to assign accession batch numbers, dates, shift identifiers, or specimen-type designations directly to the drawer for LIS-compatible batch tracking without per-cassette external labeling at the staging stage.
Are other colors available for color-coded staging systems?
Yes — a green 400-capacity drawer (part number 258-4200-G10) is also available from LabSupplies.com, enabling procurement of multiple drawer colors from a single authorized source for multi-category or day-of-week color-coded cassette staging systems.
Will these drawers fit standard cassette storage cabinets and grossing bench shelving?
The drawers are designed to stack on standard grossing bench shelving and slide into cassette storage cabinet rails without auxiliary hardware or modification. Verify your cabinet rail dimensions against the drawer footprint if deploying into a proprietary storage system.
