Histo-Click™ 20 mL Click-Top Cap Containers — HDPE, Green, 1000/Bag (300-7020-G20)
The Histo-Click™ line delivers 20 mL click-top cap containers molded from high-density polyethylene (HDPE) in a distinctive green color, supplied non-sterile in bulk 1000/Bag packaging for high-throughput histology and general specimen-handling workflows. The click-top closure provides a positive, audible snap that helps confirm a secure seal during routine capping, reducing the risk of accidental leakage during transport or storage. Part number 300-7020-G20 is well suited to laboratories requiring a reliable, color-coded container at scale.

- Routine tissue and biopsy specimen transport between collection and processing areas
- General-purpose liquid and solid specimen containment requiring a secure snap closure
- High-volume workflows where bulk packaging reduces per-unit cost and restocking frequency
Material & Chemical Resistance
High-density polyethylene offers broad resistance to aqueous solutions, dilute acids and bases, and many common laboratory reagents, making it a practical choice for a wide range of specimen-handling applications. HDPE is rigid yet tough and provides good impact resistance during routine handling and transport. As with all polyethylene labware, HDPE is not recommended for autoclaving, and compatibility should be verified before use with concentrated oxidizing acids, aromatic solvents, or chlorinated solvents.
Quality & Procurement
Made in USA, Caplugs® Evergreen Histo-Click™ containers are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free HDPE resin. LabSupplies.com is an authorized dealer and ships from USA inventory, typically same business day for stocking items, with tiered pricing available for institutional, hospital, and grant-funded laboratories.
Frequently Asked Questions
Are these containers sterile?
No — the 300-7020-G20 containers are supplied non-sterile in 1000/Bag bulk packaging, which is standard for most histology and general specimen-handling applications where sterility is not required.
How does the click-top closure work, and does it provide a leak-resistant seal?
The click-top design snaps closed with an audible click that provides tactile and auditory confirmation of engagement, helping to reduce accidental opening. As with any snap-fit closure, users should confirm the cap is fully seated before transporting liquid-containing specimens.
Can HDPE containers be used with formalin or other fixatives?
HDPE generally demonstrates good resistance to aqueous-based fixatives such as neutral buffered formalin; however, chemical compatibility should always be verified against the specific fixative formulation and concentration before routine use.
