30 mL Centrifuge Tubes, White — 388-5928-W30 | 100/Bag | Caplugs® Evergreen

Tamper Evident Boxes for 2 × 30 mL Centrifuge Tubes — Polypropylene, White, 100/Bag (388-5928-W30)

These tamper evident boxes are designed to hold two 30 mL centrifuge tubes and provide a secure, tamper-indicating closure for sample chain-of-custody and transport integrity. Molded from white polypropylene, each box offers durability and resistance to common laboratory reagents, making them practical for specimen handling, storage, and shipping workflows. Supplied non-sterile in convenient bulk packaging of 100 per bag, part number 388-5928-W30 is well suited to high-throughput labs requiring reliable sample security.

Technical Specifications

Applications

• Chain-of-custody packaging for clinical and diagnostic specimens in centrifuge tubes
• Secure transport of sample-containing centrifuge tubes between collection sites and laboratories
• Storage organization where tamper-evident closure is required for regulatory or compliance purposes
• Biorepository and sample archiving workflows requiring secondary containment
• General laboratory sample management where dual-tube secure packaging is needed

Material & Chemical Resistance

Polypropylene is a robust, semi-rigid thermoplastic with good resistance to aqueous buffers, dilute acids and bases, and alcohols, making it appropriate for a wide range of laboratory environments. These boxes can withstand typical autoclave temperatures if sterilization of the secondary packaging is required, though the tamper evident closure mechanism should be evaluated before autoclaving. As with all polypropylene labware, avoid prolonged contact with chlorinated solvents and aromatic hydrocarbons, which can degrade the material.

Quality & Procurement

Made in USA, Caplugs® Evergreen tamper evident boxes are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free polypropylene 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 grant-funded laboratories.

Frequently Asked Questions

Are these tamper evident boxes sterile?
No — they are supplied non-sterile in 100/Bag bulk packaging. They are intended as secondary containment and transport packaging rather than sterile specimen containers.

What size centrifuge tubes do these boxes accommodate?
Each box is sized to hold two 30 mL centrifuge tubes. Compatibility with tubes of different volumes or outer diameters is not guaranteed, as fit depends on the individual tube dimensions.

Can polypropylene tamper evident boxes be used with alcohol-based disinfectants on the outer surface?
Polypropylene has good resistance to alcohols, so brief surface contact with common alcohol-based disinfectants is generally acceptable. Avoid prolonged immersion or contact with chlorinated or aromatic solvents, which can degrade the material.
