Applications
- Replacement closures for 150 mL specimen containers in clinical and research laboratories
- Bulk recapping of containers during high-throughput sample collection and processing
- Secure sealing of biological and environmental specimens during transport and storage
- General-purpose container closures for aqueous reagents, buffers, and dilute chemical solutions
- Inventory replenishment for laboratories that replace caps independently of containers
Material & Chemical Resistance
High-density polyethylene provides good general chemical resistance to aqueous solutions, dilute acids and bases, and many common laboratory reagents, making it well suited for routine specimen containment. HDPE is more rigid than low-density polyethylene and maintains its shape under normal handling and storage conditions. Note that HDPE is not recommended for autoclaving, and resistance to chlorinated or aromatic solvents is limited; verify compatibility before use with aggressive chemicals.
Quality & Procurement
Made in USA, Caplugs® Evergreen specimen container caps 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 and high-volume procurement accounts.
Frequently Asked Questions
Are these screw caps sterile?
No — they are supplied non-sterile in 250/Bag bulk packaging. For applications requiring sterile closures, a sterilization step or an alternative sterile-supplied product would be necessary.
Are these caps sold separately from the specimen containers?
Yes. These are caps only and are intended for use as replacement or supplemental closures for compatible 150 mL specimen containers.
Can HDPE caps be autoclaved for sterilization?
HDPE is generally not recommended for autoclaving, as the elevated temperatures and steam conditions can distort or compromise the cap. Alternative sterilization methods, such as chemical disinfection where appropriate, should be considered.
