20 mL Freestanding Vials, Natural Cap — Polypropylene Copolymer, Non-Sterile, 1000/Bag (240-3519-080)
These 20 mL freestanding vials from Caplugs® Evergreen are molded from polypropylene copolymer (PPC) and fitted with natural (clear) caps, making them a versatile choice for clinical specimen collection, reagent aliquoting, and sample archiving across high-volume laboratory workflows. The flat-bottom freestanding base allows each vial to stand independently on the bench without a rack, streamlining processing and organization during busy runs. Supplied non-sterile and unassembled in a 1000/Bag format, part number 240-3519-080 is well suited for facilities that demand compact storage and cost-effective per-unit pricing at scale.

Applications
- Urine culture and urinalysis — the 20 mL capacity accommodates large-volume specimen collections without risk of insufficiency
- Molecular and genomic workflows — PPC material is compatible with DNA/RNA specimens and common molecular reagents
- Reagent aliquoting and buffer preparation — freestanding base keeps vials stable during pipetting and dispensing steps
- Sample archiving and long-term storage — natural cap maintains full label visibility on both the vial body and cap surface for direct labeling
- Environmental and industrial sample collection — large volume and chemical resistance support diverse matrix types
- LIMS and barcode-integrated workflows — smooth label-compatible vial surface supports direct printing and barcode scanning

Frequently Asked Questions
Are these vials sterile?
No — they are supplied non-sterile and unassembled in 1000/Bag packaging. For workflows requiring sterile vials, please contact us to discuss alternative options within the Caplugs® Evergreen line.
Do the vials need a rack to stand upright?
No — the flat-bottom freestanding base allows each vial to stand independently on any level bench surface, eliminating the need for a rack during processing, aliquoting, or temporary staging.
Why choose a natural cap over a colored cap?
Natural (clear) caps are ideal for general-purpose workflows where a specific color-coding scheme is not in use, and they preserve full visibility of any label applied directly to the cap top — useful for LIMS barcodes, lot numbers, or handwritten identifiers.
Is polypropylene copolymer suitable for molecular specimens such as DNA or RNA?
Yes — polypropylene copolymer provides broad compatibility with biological specimens and the aqueous buffers, salts, and mild detergents commonly used in molecular workflows. It is not recommended for use with chlorinated or aromatic solvents such as chloroform or acetone.
