10–15 mL Centrifuge Tubes, Screw Caps, HDPE, Natural — 222-3615-080 | 25/Bag | Caplugs® Evergreen

15 mL Sterile PPC Transport Vials with Screw Caps, Natural — 25/Bag Unassembled (222-3615-080)

These 15 mL polypropylene copolymer (PPC) transport vials are supplied sterile, unassembled (tube and natural screw cap in the same bag), in a convenient 25/Bag pack size. Part number 222-3615-080 represents the largest vial in the Caplugs® Evergreen sterile transport series, offering the capacity of a standard 15 mL conical in a dedicated specimen transport format suited to high-volume clinical collection workflows. The natural PPC construction provides optical clarity for visual specimen inspection and full compatibility with common transport media, preservatives, and organic solvents used in modern clinical and molecular laboratories.

Technical Specifications

Applications

• Stool and fecal specimen collection with transport media (e.g., Cary-Blair), where the 15 mL capacity accommodates high-volume fecal collection devices
• 24-hour urine sub-aliquoting for protein, creatinine, and electrolyte analysis — PPC is fully compatible with boric acid urine preservatives
• Large-volume body fluid transport, including pleural, ascitic, and synovial fluid aliquots requiring a secure screw-cap closure
• Stool culture and anaerobic enteric pathogen transport in Cary-Blair and equivalent media
• Molecular diagnostic pre-transport collection for NAAT and PCR workflows — PPC supports full methanol compatibility for downstream extraction
• Viral and universal transport media (UTM/VTM) specimen collection for respiratory or enteric pathogens
• Sterile reagent and media transfer between laboratory sites, with screw-cap closure preventing leakage in transit
• Reference laboratory sub-aliquoting from primary 15 mL conical tubes, matching the standard tube format for seamless integration into existing workflows

Quality & Procurement

Made in USA, these Caplugs® Evergreen transport vials are manufactured from BPA-free, phthalate-free, latex-free PPC resin under rigorous quality controls, and are supplied sterile for direct use in clinical specimen collection and transport. LabSupplies.com is an authorized dealer of Caplugs® Evergreen consumables and ships from USA inventory, typically the same business day for stocking items. Laboratories requiring larger volumes should inquire about the 1000/Bag format (222-3615-08K); the 10 mL companion vial is also available (222-3010-080). Tiered pricing is available for high-volume institutional and reference laboratory accounts.

Frequently Asked Questions

Are these vials supplied sterile and ready for specimen collection?
Yes — the vials are sterile as supplied. They are shipped unassembled, meaning the tube and natural screw cap are packaged together in the same bag but not pre-assembled, allowing users to assemble them under appropriate conditions before collection.

Is polypropylene copolymer (PPC) compatible with viral and universal transport media?
Yes. PPC is fully compatible with VTM, UTM, and common enteric transport media such as Cary-Blair, making these vials suitable for a broad range of clinical specimen transport workflows without risk of media degradation or tube failure.

Can these vials be used for 24-hour urine collection and sub-aliquoting?
Absolutely. The 15 mL capacity is well suited to sub-aliquoting from a 24-hour collection container, and PPC is chemically compatible with boric acid, the most widely used urine preservative for protein, creatinine, and electrolyte testing.

What is the difference between this pack size and the 1000/Bag option?
Both contain the same 15 mL sterile PPC transport vial; the 25/Bag format (222-3615-080) is suited to lower-volume users, point-of-care settings, or labs that prefer smaller lot sizes for inventory management, while the 1000/Bag format (222-3615-08K) offers better per-unit economics for high-throughput reference or clinical laboratories.
