120 mL Specimen Containers with Screw Caps — Polypropylene, Natural, 25/Bag (220-5614-03K)
These 120 mL polypropylene specimen containers feature a wide-mouth threaded neck with a secure screw cap, making them the workhorse choice for surgical pathology and histology laboratories that require reliable formalin fixation and long-term tissue archiving. Supplied non-sterile in convenient 25/Bag packaging, the natural (translucent) color allows direct visual confirmation of specimen presence and fixative fill level without opening the container. The wide mouth accommodates direct tissue placement and spatula access during grossing, while the threaded closure provides a re-sealable, leak-resistant seal suited for formalin transport and archival storage.

Applications
- Tissue and biopsy fixation: Wide mouth allows direct placement of surgical and biopsy specimens into formalin or other fixatives at the grossing station
- Formalin fixation workflows: Polypropylene provides full chemical compatibility with 10% neutral buffered formalin and other formaldehyde-based fixatives at standard concentrations
- Intraoperative / frozen section specimens: Wide opening accommodates spatula access for rapid tissue handling during intraoperative pathology
- Archival specimen storage: Threaded screw cap delivers a re-sealable, secure closure for long-term storage in pathology archives
- Biobank and research pathology: Suitable for formalin-fixed tissue archiving and cryoprotectant-compatible specimen preservation in biorepositories
- Environmental and food testing: The 120 mL wide-mouth format supports swab collection and large-volume sample handling in testing laboratory settings
- Specimen transport: Leak-resistant threaded closure makes these containers appropriate for transport of formalin-fixed specimens by courier or mail
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Aqueous buffers / saline (pH 2–12) | Excellent |
| Formaldehyde / formalin (10%) | Excellent |
| Glutaraldehyde | Excellent |
| Bouin's solution (picric acid-based) | Excellent |
| Methanol / acetonitrile (<100%) | Excellent |
| Dilute acids and bases | Excellent |
| Ethanol (<70%) | Good — short-term contact |
| Dichloromethane / chloroform | Not recommended — causes cracking |
| Tissue / biological specimens | Excellent |

Frequently Asked Questions
Are these specimen containers sterile?
No — these containers are supplied non-sterile. For routine formalin fixation and histology workflows, sterility is not required; the fixative itself acts as a preservative. If your protocol requires sterile containers, please contact us for available alternatives.
Are these containers compatible with formalin and Bouin's solution?
Yes. Polypropylene has excellent chemical resistance to formaldehyde-based fixatives, including 10% neutral buffered formalin, as well as picric acid-based Bouin's solution and glutaraldehyde used in electron microscopy fixation. Dichloromethane and chloroform should be avoided, as these cause cracking in polypropylene.
Is the wide-mouth opening large enough for tissue specimens?
The wide-mouth threaded design is specifically suited for direct tissue and biopsy specimen placement and allows spatula access during grossing — making it practical for routine surgical pathology and intraoperative frozen section workflows.
Can the containers be resealed after opening, and are they suitable for formalin transport?
Yes. The threaded screw cap provides a secure, re-sealable closure that is appropriate for long-term archival storage and for transport of formalin-fixed specimens. Always verify that your institution's shipping and hazmat protocols are satisfied before transporting formalin-containing containers.
