You can use different cassette colors to separate specimen types, departments, processing batches or priority levels. Instead of relying only on printed text, your team gains an immediate visual reference throughout tissue processing, embedding, storage and retrieval.
Core Cassette Features
Our tissue and biopsy cassettes are made of POM to help reduce wax-block deformation during embedding, freezing and sectioning.
You can select models suitable for inkjet, thermal-transfer or laser cassette printers. Compatibility varies by model.
We offer 10 standard colors to help you separate specimen types, departments or workflows: white, green, yellow, blue, pink, orange, purple, aqua green, rose red and brown.
You can request bulk bags, preloaded tubes or taped strips. Preloaded and taped formats can reduce manual loading when you use compatible cassette printers.
Biopsy Cassette Models
For small biopsy specimens, you can choose a 1.6 mm large-square grid or a 0.7 mm fine-square grid. All models below are POM cassettes for automatic cassette printers, but the writing angle, lid structure and packing method vary by code.
