Biopsy Cassettes

<h2 data-section-id="1l9wr55" data-start="0" data-end="29">What Are Biopsy Cassettes?</h2>
&nbsp;
Biopsy cassettes are specialized histology cassettes manufactured from acetal polymer (POM) and designed with fine 1 mm square mesh openings instead of the wider slots used in standard tissue cassettes. These fine mesh openings securely retain small tissue specimens such as gastric endoscopic biopsies, prostate needle cores, liver biopsies, and skin punch biopsies that could otherwise be lost during tissue processor agitation, vacuum cycles, and reagent exchanges. Like standard tissue cassettes, biopsy cassettes function as the specimen container throughout processing, embedding, and long-term paraffin block storage. Multi-compartment designs allow multiple tissue cores from different anatomical sites to be processed together while maintaining specimen orientation and identification.
Use biopsy cassettes for specimens smaller than approximately 3 mm. The fine 1 mm mesh is the key feature that prevents specimen loss during processing.

&nbsp;
Single vs. Multi-Compartment
Single-compartment biopsy cassettes are the standard choice for processing one specimen per paraffin block and are suitable for most diagnostic biopsy applications. Multi-compartment cassettes, including four-compartment and six-compartment formats, allow several biopsy cores from different anatomical locations to be processed in the same cassette while preserving their positional identity. These formats are commonly used for prostate biopsy series and other multi-site sampling procedures.
Mesh Opening Size
Standard biopsy cassettes feature 1 mm square mesh openings that provide an effective balance between specimen retention and reagent flow. For ultrafine tissue cores, dispersed cell pellets, or particularly delicate specimens, microbiopsy or biomesh cassettes with smaller openings ranging from approximately 0.38 mm to 0.6 mm may provide better specimen containment.
Lid Design and Printer Compatibility
Globe Scientific biopsy cassettes utilize an integral click-shut hinged lid that closes securely and can be reopened multiple times without compromising closure integrity. This design is particularly useful during grossing procedures where specimens may need to be inspected before processing. Writing surfaces are available in both 30&deg; and 35&deg; angles to ensure compatibility with Leica and Sakura cassette labeling systems.
Foam Biopsy Pads
Biopsy foam pads are commonly used when processing extremely small tissue fragments. These polyester urethane foam inserts help immobilize specimens within the cassette, maintaining proper orientation and preventing movement during tissue processing while still allowing efficient reagent penetration and drainage.
Compatibility with Base Molds
Biopsy cassettes share the standard histology cassette footprint of approximately 40 &times; 28 &times; 6 mm, allowing compatibility with standard stainless steel and disposable plastic embedding molds. Multi-compartment designs maintain the same external dimensions while providing internal specimen separation.

&nbsp;
Globe Scientific biopsy cassettes are manufactured from durable acetal polymer and feature 1 mm square mesh openings engineered to maximize specimen retention while allowing efficient reagent penetration. The fine mesh design provides a large total open surface area for fluid exchange despite the smaller individual openings. These cassettes are resistant to formalin, xylene, graded alcohols, and acidic decalcifying agents commonly used in histology laboratories. The standard footprint of approximately 40 &times; 28 &times; 6 mm ensures compatibility with Leica ASP, Sakura VIP, Thermo Shandon Excelsior, and most other automated tissue processors. Globe Scientific maintains ISO 9001:2015 certification, and lot-specific conformance documentation is available upon request through MBP.

Tissue Cassettes

<h2 data-section-id="12g32xm" data-start="194" data-end="223">What Are Tissue Cassettes?</h2>
&nbsp;
Tissue cassettes are rectangular acetal polymer (POM) containers used in surgical pathology and research histology to carry gross tissue specimens&mdash;including resections, excisions, and large biopsy cores&mdash;from the grossing table through the complete paraffin processing workflow. Wide-slot perforations (approximately 1.5 mm) allow rapid reagent penetration and drainage during automated tissue processor cycles while preventing specimen loss for samples measuring 3 mm or larger in their smallest dimension. Following processing, the cassette base fits directly into a metal or disposable plastic base mold for paraffin embedding, and the completed paraffin block is archived with the cassette serving as the primary specimen identifier.
Standard tissue cassettes handle the majority of surgical pathology specimens; use biopsy cassettes for specimens smaller than approximately 3 mm.

&nbsp;
Writing Area Angle: 30&deg; vs. 35&deg;
Globe Scientific tissue cassettes are available with 30&deg; and 35&deg; angled writing surfaces to match Leica and Sakura cassette printer platen angles. Selecting the incorrect angle can create printing alignment issues and slow workflow efficiency. Laboratories should verify printer specifications before ordering case quantities.
Integral Lid vs. Separate Lid
Integral hinged-lid tissue cassettes snap closed without requiring a separate steel lid, reducing handling steps in high-volume grossing environments. Separate-lid cassettes are compatible with standard metal base molds and are often preferred in embedding stations where lids must be removed independently. Both formats are compatible with standard tissue processor baskets.
Color Coding
Globe Scientific offers tissue cassettes in more than ten standard colors. Many laboratories assign colors by specimen type or department to improve organization and reduce the risk of specimen identification errors during high-volume processing.
Pack Format: Standard Box vs. QuickLoad Sleeves
Standard 500-count dispenser boxes meet the needs of most laboratories. QuickLoad&reg; and E-Z Load&reg; sleeve formats provide pre-counted cassette stacks for rapid one-handed dispensing and are particularly useful in grossing stations processing more than 300 specimens per day.
Compatibility with Tissue Processors
The standard 40 &times; 28 &times; 6 mm cassette footprint is compatible with Leica ASP, Sakura VIP, Thermo Shandon Excelsior, and most other automated tissue processors without modification. Compatibility should be verified when ordering Mega or deep-body cassette variants.

Acetal polymer cassettes are dimensionally stable from 4&deg;C refrigerated storage through approximately 65&deg;C during paraffin infiltration. Globe Scientific maintains ISO 9001:2015 quality management certification, and lot-specific conformance documentation is available upon request. The standard 40 &times; 28 &times; 6 mm footprint is widely accepted by major tissue processor manufacturers and does not require instrument-specific modification. Tissue cassettes are research-use consumables and are not classified as medical devices or in vitro diagnostic (IVD) products.
