Precision-Engineered for Maximum Sample Recovery, Secure Sealing, and Contamination-Free Workflows
Thermo Scientific™ Snap Cap Low Retention Microcentrifuge Tubes are engineered to deliver exceptional sample recovery and contamination control in high-precision laboratory workflows. These tubes are manufactured from virgin polypropylene, ensuring durability, purity, and chemical resistance across a wide range of molecular biology, clinical, and industrial applications.
With their low retention surface—achieved without the use of coatings or additives—these tubes significantly reduce sample loss, making them especially effective for viscous liquids, low-volume reagents, and costly biomolecules. The unique duckbill snap cap design ensures a leak-proof seal during centrifugation and sample transport, while still allowing for easy, one-handed operation.
Available in 0.6 mL, 1.5 mL, and 2.0 mL sizes, and with both sterile and non-sterile options, these tubes support efficient, scalable workflows in molecular biology, diagnostics, biopharma, and general laboratory use.
Key Features & Benefits
1. Superior Sample Recovery with Low Retention Design
- Reduces protein and nucleic acid binding to tube walls for maximum recovery
- No coatings or embedded additives—ensures compatibility with sensitive downstream assays
- Ideal for PCR/qPCR, NGS, enzyme reactions, and other low-volume applications
2. Snap Cap with Duckbill Seal for Reliable Containment
- Secure, leak-proof duckbill snap cap maintains tight closure during centrifugation
- Easy one-handed opening and closing to improve workflow efficiency
- Ensures containment during vortexing, boiling, and transport
3. High Performance Under Stress
- Withstands centrifugation forces up to 26,000 × g
- Safe for freezing, boiling, and exposure to a wide range of chemicals and buffers
- Graduated markings for accurate volume measurement
4. Contamination Control and Sterile Assurance
- Sterile versions are certified free of RNase, DNase, DNA, ATP, bioburden, and endotoxins
- Non-sterile versions are free of RNase, DNase, DNA, and pyrogens
- Manufactured under stringent quality standards for molecular and clinical use
5. Customization & Color Options
- Available in natural, amber (light-sensitive), red, blue, green, yellow, and violet
- Multiple packaging options including bulk cases and individually wrapped packs
- Compatible with automated liquid handling systems for high-throughput operations
