SP Prefilled Formalin Specimen Containers

Pathology labs and specimen collection sites depend on prefilled formalin containers to move tissue samples from the procedure room to histology without delay or exposure risk. This collection features SP-brand specimen transport containers designed around one goal: getting a specimen into fixative fast, safely, and with the right formalin-to-tissue ratio already measured out.

The Cardinal Health SP Prefilled Formalin Container (C4320-60B) arrives with 60 mL of 10% neutral buffered formalin sealed inside a 120 mL polypropylene jar — the standard fixative used across most clinical histology protocols. Because it comes prefilled, staff skip the hazardous step of measuring and pouring formalin at the bedside, which reduces vapor exposure and spill risk. The screw-cap closure creates a leak-resistant seal for transport, and the wide-mouth polypropylene body resists cracking while making specimen insertion and retrieval straightforward.

A common question with these containers is the fill ratio: the 60 mL fill in a 120 mL jar leaves headroom so a specimen can be fully submerged while still maintaining roughly the 10:1 fixative-to-tissue volume that pathology generally recommends for proper fixation. These units are non-sterile and single-use — appropriate for their intended role, since fixation itself is not a sterile process. Note the container is not graduated, so it's built for standard fixation and transport rather than measured collection.
