I used them to collect 50 water samples locally, kept them in ziplocs with their respective collection survey, and nothing spilled. **Q: How accurate is the graduation of these tubes?** A: Maybe the supplier has specs, but I suspect the precision is one of several more appropriate questions. It's not advertised as measuring liquids for quantitative analysis, just "solid, powder, seeds, pills, granular objects" but the volume is given to 1/10th of a milliliter. Being precise about the volume of a seed seems like an oxymoron, whereas powders are not. It will be interesting what answers you get! **Q: Is the tube and cap pp5? I'm wondering if both can withstand an autoclave.** A: The description states the blue cap is HDPE and not PP. HDPE will not withstand the heat in an autoclave. **Q: Is there a tube rack on amazon available for these tubes?** A: No specific idea, sorry, but rack is mentioned a lot on the product page. They do stand upright on their own. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***. on October 13, 2025* ### ⭐⭐⭐⭐⭐ Review *by H***T on January 24, 2020* ### ⭐⭐⭐⭐⭐ Review *by C***N on March 13, 2026* ## Frequently Bought Together - 50ml Plastic Centrifuge Tubes with Screw Cap, CertBuy 50 Pack Self-Standing Plastic 50ml Test Tube Polypropylene Conical Tubes with Cap, Graduated Marks - SimPure Centrifuge Tubes 15mL, Conical Tubes Sterile 50 PCS, Polypropylene, Leak-Proof Screw Caps, Plastic Container with Graduated and Write Marks, Non-pyrogenic, DNase/RNase Free, Human DNA-Free - Test Tube Rack, Centrifuge Tube Holder (2 Pack - Blue and Orange) for 10ml, 15ml, 50ml, Detachable Plastic Stand, 28 Well --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/130735273-50ml-plastic-centrifuge-tubes-with-screw-cap-certbuy-50-pack](https://www.desertcart.com.kw/products/130735273-50ml-plastic-centrifuge-tubes-with-screw-cap-certbuy-50-pack) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-13*
