20 mL Histo-Click™ Specimen Containers with White Snap Caps — PPC, Non-Sterile, 500/Bag (240-7020-W80)
The Caplugs® Evergreen Histo-Click™ 20 mL specimen containers are purpose-built for histopathology tissue collection, formalin fixation, and cytology workflows where one-hand operation matters in gloved surgical and grossing environments. Constructed from Polypropylene Copolymer (PPC) and supplied with white click-top snap caps, these containers are compatible with 10% neutral buffered formalin (NBF) and arrive unassembled — 500 containers and 500 caps per bag — ready for point-of-use assembly and pre-labeling. The natural tube body allows direct visual assessment of specimen volume and morphology without removing the container from the processing tray.

Quality & Procurement
Made in USA, these Histo-Click™ containers are manufactured under ISO 9001 quality management from BPA-free, phthalate-free PPC resin. The click-top snap closure eliminates the two-handed screw-threading motion that can be cumbersome in gowned and double-gloved settings, making single-use adoption practical for high-volume histopathology and cytology programs. LabSupplies.com is an authorized Caplugs® Evergreen dealer, shipping from USA inventory with tiered volume pricing available for hospitals, reference labs, and academic medical centers. White-capped containers under part number 240-7020-W80 are also complemented by blue- and green-capped variants for facilities that use color-coded specimen collection programs.
Frequently Asked Questions
Are these specimen containers sterile?
No — the Histo-Click™ 240-7020-W80 containers are supplied non-sterile. For formalin-fixed tissue collection and standard histopathology workflows, non-sterile containers are the industry norm; consult your laboratory's SOPs if sterility is required for a specific application.
Why do the containers arrive unassembled?
The unassembled format allows laboratory staff to apply specimen labels, barcodes, or LIS-generated identifiers to the container body before snapping the cap in place — supporting integrated specimen tracking workflows without a separate labeling step after capping.
Is the PPC material truly compatible with formalin?
Yes. Polypropylene Copolymer (PPC) provides reliable resistance to 10% neutral buffered formalin at standard tissue fixation concentrations, which is why it is the preferred polymer for histopathology specimen containers. Avoid prolonged contact with chlorinated or aromatic solvents, which are outside the intended use of these containers.
Can these containers be color-coded with other cap colors?
Yes. The Histo-Click™ 20 mL container is available with blue and green snap caps in addition to this white-capped version, allowing procurement teams to implement a cap color-coding scheme across specimen types or collection sites without changing the container itself.
