Products for Centrifugal Separation
High-Quality Medical-Grade Polypropylene (PP): Constructed from virgin PP for excellent chemical resistance, high transparency, and low extractables.
Wide Range of Sizes: Available in standard 15 mL and 50 mL capacities, suitable for cell culture, molecular biology, and clinical applications.
Leak-Proof, Secure Sealing Caps: Screw caps with precision threading ensure tight, leak-free sealing during centrifugation and storage.
Withstands High Centrifugal Force: Rated up to 12,000×g (15 mL) and 15,000×g (50 mL), compatible with most high-speed centrifuge models.
- Clear, Easy-to-Read Graduations: Molded or printed graduation marks with ±2% accuracy for precise volume measurements.
High-Purity Medical-Grade Polypropylene (PP): Made from virgin polypropylene for excellent chemical resistance, low protein binding, and high transparency.
Leak-Proof Snap-Cap Design: Secure, tight-fitting cap ensures reliable sealing, even during high-speed centrifugation, and prevents sample evaporation or leakage.
Available in Multiple Sizes: Offered in 0.5 mL, 1.5 mL, and 2.0 mL volumes to support a wide range of sample preparation and storage needs.
Withstands High Centrifugal Force: Rated up to 20,000×g (varies by model), ideal for demanding molecular biology and biochemistry protocols.
- Graduated and Frosted Surface Options: Clear printed graduations for accurate volume reading; optional frosted area for easy labeling and sample identification.
Durable, High-Speed-Resistant Materials: Made from premium-grade polypropylene (PP) or polycarbonate (PC), offering exceptional strength and resistance to centrifugal forces up to 7,000×g (depending on model).
Large Volume Capacity: Available in 250 mL, 500 mL, and custom volumes to accommodate large-scale separations and high-volume sample processing.
Leak-Proof Screw Cap Design: Features robust sealing caps with O-rings or plug-seal options to prevent leakage during high-speed centrifugation.
- Excellent Chemical Resistance: Compatible with a wide range of laboratory reagents, solvents, and buffers commonly used in cell culture and biochemical workflows.
- Clear and Impact-Resistant: High-clarity bottles allow visual inspection of contents; impact-resistant structure ensures safety during handling.
centrifuge tube holder
Compatible with Various Tube Sizes: Designed to securely hold 5 mL, 15 mL, and 50 mL centrifuge tubes for a wide range of laboratory applications.
Autoclavable and Reusable: Withstands high-temperature sterilization (up to 121°C), making it ideal for sterile environments and repeated use.
Stable and Non-Slip Design: Firm base ensures stability on the benchtop; prevents tipping or accidental spillage during tube handling.
Stackable and Space-Saving: Stackable models allow for efficient storage in lab freezers, refrigerators, or workstations.
Easy to Clean and Maintain: Smooth surface minimizes residue buildup and simplifies cleaning between uses.

Frequently Asked Questions
What materials are Sdlabio centrifuge tubes made from?
Sdlabio tubes use medical-grade polypropylene (PP), offering excellent chemical resistance, clarity, and low extractables—typical of high-quality PP tubes
Should we use conical or flat-bottom tubes?
Conical tubes are ideal for microcentrifuge use and precipitate collection, while flat- or round-bottom types save space and are suited for free-standing protocols.
Are they nuclease-free and autoclavable?
Yes. Made in cleanroom environments and certified free of DNase, RNase, and pyrogens. Safe for autoclaving at 121 °C and for low-temperature storage.
What rack types does Sdlabio offer?
A range of polypropylene tube racks, including micro‑tube racks, 15 mL/50 mL multi‑tier and collapsible designs, supporting organized storage and pipetting
What capacities can tube racks hold?
Racks may accommodate up to 25 × 1.5 mL micro‑tubes, 18 × 50 mL tubes, and combination racks for both 15 mL and 50 mL sizes.
Are racks collapsible or stackable?
Yes, many Sdlabio racks are stackable or collapsible, saving bench space and easy to store or ship.
Do the racks come in different colors?
Yes. Sdlabio offers color-coded racks to help with sample identification and organization. Custom color options are also available for OEM orders.
