Introduction & Positioning

The Clinsam 02514 Conical Centrifugal PS Tubes represent the next-generation standard in polystyrene (PS) conical-bottom centrifuge consumables, designed for laboratories demanding precision, reliability, and cost-effectiveness. These tubes are ideal for cell biology, molecular biology, biochemistry, microbiology, diagnostics, and clinical research workflows.

Product Features

Here is a detailed breakdown of the key features of the Clinsam 02514 Conical Centrifugal PS Tubes:

Material & Construction

• Polystyrene (PS) composition: The body is molded from high-grade, optical‑quality polystyrene, offering excellent transparency for easy visual inspection of samples.
• Medical-grade: Ensures uniformity, minimal extractables, and compatibility with a wide range of reagents, buffers, and conditions.
• Seamless conical bottom: The conical tip is precision molded (not glued), ensuring smooth, uninterrupted geometry for efficient pellet formation and minimal retention of residues.
• Wall thickness: Tight tolerances on wall thickness mitigate stress points and reduce the chance of cracking under load or during centrifugation.

Feature of Conical Centrifugal Tube

Dimensions & Volume

• Nominal capacity: (For example) 15 mL (you should insert the actual capacity for your model).
• Graduation markings: Clearly molded graduations in 0.5 mL (or appropriate) increments, with contrast lines for readability.
• Design envelope: Outer diameter ~16 mm, length ~100 mm (or per spec) to be compatible with standard rotor buckets or tube holders.

Dimension of Conical Centrifugal Tube

Centrifugal & Thermal Performance

• High speed compatibility: Designed to withstand up to, e.g., 10,000 × g or more (depending on spec) without deformation or failure.
• Freeze-thaw stability: Can reliably endure multiple freeze-thaw cycles (e.g., to –80 °C and back to ambient) without cracking.
• Autoclavable: Capable of steam sterilization (121 °C, 15 psi, 20 minutes) without significant warping or damage.
• Broad temperature range: Usable across –80 °C to +120 °C (or the relevant spec) with minimal dimensional change, enabling broad applications from cold storage to heated incubation steps.

Chemical, Biological, & Cleanliness Compatibility

• Chemical resistance: Resistant to many common aqueous buffers, acids, bases, and organic solvents (within PS compatibility limits).
• Low extractables & leachables: Manufacturing and curing conditions are optimized to minimize leachable residues, preserving sample integrity.
• Sterility options: Available in non‑sterile bulk form or gamma-irradiated sterile packs, with assurances of DNase/RNase-free, pyrogen-free, and endotoxin-free specifications if required.
• Marked “cleanroom-manufactured”: Produced under ISO clean-room conditions (e.g., ISO Class 8 or better) to minimize particulate contamination.

Packaging & Handling

• Bulk packaging: Tubes may come in packs of 500 or more per case, with internal bags or trays to protect against scratches.
• Rack compatibility: Tubes designed to sit in standard tube racks and grid systems without wobble.
• Ease of labeling: Each tube features a frosted writing area (or molded flat panel) for markers or barcodes, with durability to ethanol or isopropanol wiping.
• Cap compatibility: Compatible with standard screw-cap or plug-style closures (HDPE or compatible materials), ensuring a tight seal during centrifugation and handling.

Quality, Reliability & Safety Claims

Quality Assurance & Certification

• ISO-based manufacturing: Produced in facilities certified to ISO 9001 and ISO 13485 (if applicable) to ensure robust quality systems.
• Cleanroom production environment: Manufactured in ISO Class 7 or 8 cleanrooms, minimizing particulate contamination.
• In-process inspections: Each batch undergoes dimensional checks, thickness profiling, and visual inspection for flaring, warpage, and defects.
• Batch-level traceability: Each lot is tracked from raw resin to final shipping carton, enabling full traceability for QC and audit purposes.

Durability & Fail-Safe Warnings

• Crack-resistance: The design and polymer grade are chosen to resist micro-cracking under repeated centrifugation or shock.
• Thermal cycling resilience: Tubes maintain structural integrity through many freeze-thaw or heating cycles typical of lab use.
• Leak integrity: O-ring or compression designs (in accompanying caps) help prevent leaks even under negative or vacuum pressure.
• Safety margins: Designed with a margin beyond typical operating conditions (e.g., rated to 1.5× or 2× standard speeds) to reduce risk of catastrophic failure.

Why Clinsam 02514 Conical Centrifugal PS Tubes Are the Smart Choice for Your Lab

In fast-paced research labs, reliability and clarity matter. You need consumables you can trust every single time. That’s why Clinsam is proud to introduce the 02514 Conical Centrifugal PS Tubes, engineered to deliver consistent performance, ease-of-use, and real-world affordability.

1. Unmatched Clarity with Premium PS Construction

Every 02514 tube is molded from high-purity, medical-grade polystyrene resin, delivering an ultra-clear, optical-grade finish. The tubes’ smooth, seamless walls reduce sample adsorption and simplify visual assessment.

2. Precision Engineering for Reliable Centrifugation

At the heart of 02514’s design is the conical bottom — precision molded, not glued — delivering consistent fluid dynamics and optimal pellet formation. The internal geometry ensures that your samples flow smoothly to the tip, enhancing recovery and minimizing residual liquid. With tight tolerances on wall thickness and internal diameter, each tube behaves predictably in your centrifuge run.

3. High-Speed & Thermal Performance You Can Trust

Whether you're spinning at 8,000 x g or pushing close to industry limits, the 02514 tubes are engineered to endure. The materials and geometry have been stress-analyzed to resist deformation at or beyond operational expectations. From freezing at –80 °C to incubating at mild heat levels, the tubes withstand thermal cycling with confidence — making them suitable for workflows that include freezing, thawing, heating, or extended storage.

4. Efficiency Meets Practicality with Graduation & Labeling

Accurate measurements matter. That’s why each tube includes crisp, molded graduation lines (e.g., every 0.5 mL) with contrast detail to avoid misreading. A frosted or molded label panel accepts markers or labels that resist smudging or degradation during routine handling or alcohol wiping.

5. Built for the Lab — Packaging & Usability

02514 tubes ship in lab-friendly bulk packaging — typically 500 or more per case — with internal protective bags or trays to prevent scratches or scuffs. The tubes are designed to sit flush in standard racks and holders, eliminating the need for custom adapters. Their robust design also resists damage during shipping, handling, or freezer storage.

6. Quality That Speaks for Itself

From raw resin sourcing to final packing, the 02514 series is built under ISO 9001 / ISO 13485 frameworks, with clean-room production and stringent in-process inspections. Each lot is traceable, and QC checks include dimensional accuracy, wall uniformity, visual clarity, and leak integrity. For sterile versions, finishing QC includes nucleic acid and endotoxin assays.

8. Advantages Over Generic or Legacy Tubes

• Lower breakage rates translate to fewer lost samples and less wasted time.
• Clearer optics enhance visual diagnostics and reduce misreads.
• More consistent behavior means fewer surprises when scaling runs or switching rotors.
• Competitive pricing deflates the common “high-quality = high-cost” equation.
• Flexible options (sterile, bulk, custom) let customers pay only for what they need.

9. Application Excellence Across Disciplines

From cell pellets in mammalian culture to bacterial or yeast harvests, from plasma separation in diagnostics to protein fractionation in biotech labs, 02514 handles it all. It’s equally suited to molecular workflows, buffer-based extractions, and general lab uses. For labs needing reliable conical tubes that bridge everyday routines and advanced workflows, Clinsam Conical Centrifugal Tube is the answer.

10. Usage Best Practices & Notes

• Always balance your rotor and avoid exceeding specified maximum RCF.
• Do not exceed the maximum fill volume (e.g. never overfill beyond the brim line).
• Warm up from –80 °C slowly; avoid thermal shock.
• Use compatible caps or closures to maintain leak integrity.
• Avoid aggressive solvents incompatible with polystyrene (e.g., certain halogenated organics).
• Discard tubes if you observe stress cracks, crazing, or deformation.
