As a crucial volumetric supplement in laboratory consumables, the 25 mL centrifuge tube fills the capacity gap between standard 15 mL and 50 mL tubes, delivering the sweet spot for medium-to-large volume sample handling.
Manufactured from medical-grade Polypropylene (PP), A-Gen 25 mL centrifuge tubes combine high mechanical strength, exceptional chemical resistance, and ergonomic convenience. They are ideally suited for centrifugation, sample storage, transport, and automated reagent dispensing—meeting stringently high standards for volume flexibility, anti-contamination protection, and workflow efficiency across biomedical research, clinical diagnostics, and industrial testing.
01 Key Differentiating Advantages
Precision Gap-Filling Design:
The 25 mL capacity perfectly covers sample processing volumes between 15 mL and 25 mL (e.g., centrifugation, cryopreservation, or aliquot transport). It prevents the inconvenience of insufficient volume in 15 mL tubes while eliminating reagent waste associated with oversized 50 mL tubes, optimizing both cost and efficiency.
Optimized Tube Opening & Height to Minimize Contamination:
Wider Opening than 15 mL Tubes: The wider tube orifice prevents pipette tips from accidentally touching the inner rim during liquid aspiration, drastically reducing cross-contamination risks.
Shorter Tube Body than 50 mL Tubes: The compact tube length allows pipette tips to reach the bottom effortlessly without inserting the entire pipette shaft deeply into the tube, avoiding shaft contact with vessel walls.
02 Key Performance Features
High Centrifugal & Thermal Resistance:
Constructed from high-purity PP, A-Gen 25 mL tubes operate reliably across temperatures from -80 °C to 121 °C (autoclavable) and withstand high centrifugal forces up to 12,000 × g, ensuring dependable performance in high-speed centrifugation.
Linerless Leak-Proof Seal:
Featuring a high-precision, linerless screw-cap mechanism, these tubes deliver a complete leak-proof seal without requiring silicone O-rings. This design eliminates potential sample contamination caused by ring degradation or chemical leaching.
Large Frosted Writing Area: Equipped with a prominent, white frosted marking area for effortless sample labeling, tracking, and organization.
03 Versatile Application Scenarios
Biomedical & Cell Biology Workflows:
Cell Culture: The 25 mL capacity matches the exact volume required for cell culture medium replacement in T-50 culture flasks, minimizing aliquoting steps, operational errors, and contamination risks.
Flow Cytometry: The wider orifice facilitates fast cell washing and buffer transfers, reducing cell retention on vessel walls.
Clinical & Diagnostic Testing:
Blood & Plasma Aliquoting: Ideal for serum/plasma sub-packaging. The wide opening prevents red blood cell lysis (hemolysis) caused by pipette tips scraping inner tube walls.
Automated Platforms: Compact tube height integrates seamlessly with liquid-handling workstations and automated analyzer racks.
Pharmaceutical & Chemical R&D:
Catalyst & Precipitate Recovery: The conical bottom and optimized height ensure complete liquid drainage and precipitate recovery, maximizing catalyst yield and reducing production costs.
