Tissue Cassettes and Embedding Media for Histology Processing
Tissue cassettes hold accessioned tissue through fixation, processing and embedding, then anchor the paraffin block on the microtome. This category stocks the cassettes, base molds, embedding rings and paraffin used at the embedding center. Formats are standardized to fit common tissue processors and embedding stations.
Cassette and Embedding Lines Stocked
- Standard tissue cassettes - Slotted and mesh cassettes with a 45-degree writing surface, stocked in printed and blank formats and across the standard color range (white, blue, green, pink, yellow, tan and others) used to code specimen batches and case types.
- Biopsy cassettes - Fine-mesh and micro-slot cassettes that retain small biopsy fragments and needle cores during processing, stocked alongside biopsy pads and wraps for the smallest specimens.
- Base molds - Stainless steel embedding base molds in the standard depth range (from shallow to deep), used with cassettes at the embedding center to form the paraffin block.
- Embedding rings and cassette lids - Plastic embedding rings and hinged-lid cassettes that seat into base molds for one-piece block handling.
- Paraffin and embedding media - Tissue embedding paraffin and blends such as Leica Paraplast and Sakura Tissue-Tek paraffin, stocked in pastille and pellet form for melting reservoirs.
Cassette Formats Available
| Format | Typical Use | Representative Brands | Configuration |
|---|---|---|---|
| Standard slotted cassette | Routine tissue sections | Sakura Tissue-Tek Uni-Cassette, Simport | 45-degree write surface, printed or blank |
| Biopsy fine-mesh cassette | Small biopsies and cores | Epredia, Simport | Fine mesh, retains fragments |
| Stainless base mold | Block embedding | Sakura, Simport | Shallow to deep depths |
| Embedding paraffin | Block infiltration and embedding | Leica Paraplast, Tissue-Tek | Pastille or pellet |
Color Coding and Cassette Marking
Cassettes are stocked in a range of colors so labs can code by specimen type, service line, priority or accessioning batch. Printed cassettes carry a pre-printed field for hand or printer marking, and blank cassettes are stocked for on-demand cassette printers. Solvent-resistant construction holds print and handwriting through xylene and alcohol processing.
Tissue cassettes are one of the highest-turn consumables on the histology bench, drawn down at the rate of every accessioned specimen block, which makes case pricing and standing orders central to keeping the embedding center stocked. Base molds, paraffin and biopsy accessories reorder alongside cassettes as a single embedding supply group for laboratory materials management. Order at the best Wholesale Prices with MAP Medical.
Frequently Asked Questions
What is the difference between standard and biopsy tissue cassettes?
Standard tissue cassettes have slotted or wide-mesh openings sized for routine tissue sections and allow free reagent flow during processing. Biopsy cassettes use a fine mesh or micro-slot pattern that retains small biopsy fragments, needle cores and tiny specimens that would pass through a standard slot. Many labs stock both, plus biopsy pads and wraps for the smallest fragments.
What cassette colors are stocked?
Cassettes are stocked across the standard histology color range, including white, blue, green, pink, yellow, tan, orange and gray, in both printed and blank formats. Color is used to code by specimen type, service line, priority or accessioning batch. Availability of a given color depends on the brand and cassette style.
Are cassettes compatible with on-demand cassette printers?
Yes. Blank cassettes are stocked for automated cassette printers and printed cassettes are stocked for hand or thermal marking. The writing and print surface is solvent-resistant so identification holds through xylene, alcohol and paraffin processing. Cassette style should match the printer and processor already installed in the lab.
Can pathology labs order tissue cassettes in bulk?
Yes. Tissue cassettes, base molds and embedding paraffin are stocked in case and bulk quantities for hospital pathology departments, reference laboratories, dermatopathology practices and licensed laboratory distributors. Standing order programs are available for high-velocity cassette colors and formats. Contact our procurement team for tiered case pricing and standing order setup.
What cassette and embedding products should be in a histology formulary?
A core embedding formulary typically covers standard slotted cassettes in the lab's coding colors, fine-mesh biopsy cassettes, stainless base molds across the depth range, embedding rings or hinged-lid cassettes, and embedding paraffin in pastille or pellet form. Biopsy pads and wraps are added for specialty specimens. MAP Medical builds consolidated embedding supply packages matched to laboratory volume - contact our team for an assessment.
