Material & Chemical Resistance
High-density polyethylene (HDPE) offers broad general chemical resistance, performing well against aqueous solutions, dilute acids and bases, and many common laboratory reagents including alcohol-based fixatives typical in cytology applications. HDPE is a rigid yet impact-resistant material that maintains its integrity under normal laboratory storage and handling conditions. Note that HDPE is not recommended for autoclave sterilization, and compatibility should be confirmed for concentrated oxidizing acids or halogenated solvents before use.
Quality & Procurement
Made in USA, Caplugs® Evergreen Slide-Fix™ screw caps are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free 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 laboratory accounts.
Frequently Asked Questions
Are these screw caps compatible with all PAP jars?
These caps are designed for use with Slide-Fix™ PAP jars. Compatibility with PAP jars from other manufacturers depends on thread size and diameter; we recommend confirming fit against your existing containers before placing a high-volume order.
Can HDPE caps be autoclaved for sterilization?
No — HDPE is not recommended for autoclave sterilization. These caps are supplied non-sterile and are intended for standard cytology and histology fixation workflows that do not require sterile closures.
What is the benefit of the green color coding?
The green color allows laboratory staff to visually distinguish these caps from other cap colors at a glance, supporting specimen organization, workflow segregation, and reduced handling errors in busy multi-specimen processing environments.
