The 2 mL collection tube is a compact, versatile solution for the secure collection, storage, and processing of biological samples in clinical, molecular, forensic, and research laboratories. Constructed from high-clarity, medical-grade polypropylene (PP) or polyethylene (PE), these tubes provide excellent resistance to chemicals, temperature fluctuations, and mechanical stress.
Key Features:
-
Capacity: 2 mL total volume, ideal for nucleic acid extraction, protein prep, and diagnostic sample handling.
-
Material: Durable, non-reactive polypropylene ensures compatibility with enzymes, buffers, and solvents used in molecular workflows.
-
Design Options: Available in conical or round bottom designs to support both centrifugation and pipetting workflows.
-
Closure Types: Snap cap, screw cap, or plug seal options provide a leak-proof and evaporation-resistant seal during storage or centrifugation.
-
Labeling: Supplied as pre-labeled or unlabeled variants, with solvent-resistant print or writable surfaces for traceability.
-
Sterility: Offered in sterile or non-sterile formats; sterile tubes are certified RNase-, DNase-, and pyrogen-free.
-
Temperature & Spin Resistance: Withstands freezing down to −80 °C and autoclaving up to 121 °C; supports centrifugal forces up to 20,000 × g (cap-dependent).
Common Applications:
-
Sample collection for DNA, RNA, or protein isolation
-
Short- and long-term biological sample storage
-
Field sample collection (e.g., swabs, saliva, lysates)
-
Clinical and diagnostic sample transport
-
Forensic specimen containment and labeling
These tubes are compatible with most automated extraction platforms and are packaged in bulk, racks, or individual pouches, depending on lab throughput needs.
