Material & Chemical Resistance
High-density polyethylene (HDPE) offers broad chemical resistance to aqueous solutions, dilute acids and bases, alcohols, and many common laboratory reagents, making it a dependable material for diverse specimen types. HDPE is a rigid yet impact-resistant thermoplastic; however, it is not recommended for autoclaving, and compatibility should be verified before use with aromatic or chlorinated solvents, concentrated oxidizing acids, or other aggressive organic chemicals.
Quality & Procurement
Made in USA, Caplugs® Evergreen specimen container screw caps are produced 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 and high-volume procurement.
Frequently Asked Questions
Are these screw caps sterile?
No — they are supplied non-sterile in 125/Bag bulk packaging. For applications requiring sterile closures, a separately sourced sterile option should be considered.
Can HDPE caps be autoclaved for reuse?
HDPE is generally not recommended for autoclave sterilization, as sustained high heat and steam can cause deformation or dimensional changes. Single-use or cold-sterilization methods are preferable where sterility is required.
What container thread size do these caps fit?
These caps are specified for 120 mL specimen containers in the Caplugs® Evergreen product line. Confirm thread compatibility with your specific containers before ordering in bulk; consult the manufacturer or LabSupplies.com for guidance if needed.
