Product Info
Centrifuge Tubes for Versatile Laboratory Workflows
Kelabscience centrifuge tubes are engineered to support a wide range of laboratory procedures, including sample separation, pellet collection, preparation steps, and temporary storage. Manufactured from high-purity polypropylene (PP), each tube offers consistent clarity, dependable mechanical strength, and chemical compatibility with common laboratory buffers and reagents.
To meet diverse experimental needs, the product line includes capacities ranging from 5 mL and 7 mL low-volume formats to 50 mL, 100 mL, and 120 mL high-capacity tubes. Multiple bottom geometries and cap configurations allow researchers to select the most suitable tube type for each centrifugation or sample-handling workflow.
For smaller-volume workflows, see our Microcentrifuge Tubes.

Applications
Kelabscience centrifuge tubes are suitable for:
-
Routine sample pelleting and separation
-
Preparation steps in molecular biology and biochemistry
-
Cell culture washing and media exchanges
-
Environmental and food-testing sample handling
-
General laboratory storage and liquid transport
-
Industrial and quality-control testing workflows
During sample preparation, accurate liquid transfer can be paired with our Filter Pipette Tips to minimize aerosol contamination and maintain sample integrity.

Structural Design & Material Performance
Each tube is precision-molded to ensure:
-
Uniform wall thickness for dependable mechanical strength
-
Smooth interior surfaces to reduce sample retention
-
Clear visibility for pellet inspection and volume assessment
-
Secure cap-to-tube engagement to minimize leakage during centrifugation and transport
Conical bottoms promote tight pellet formation, while round-bottom tubes offer reduced shear stress for sensitive suspensions.
Cap Options & Handling Convenience
Screw-cap designs provide reliable sealing for routine laboratory workflows, while optional color-coded caps improve visual identification in high-throughput environments. All tube and cap components use materials compatible with standard laboratory handling practices.
Packaging Options
To support bulk laboratory use, tubes are packaged according to capacity:
-
5–10 mL: 100 pcs/bag
-
15–30 mL: 50 pcs/bag
-
50–120 mL: 25 pcs/bag
This structure maintains efficient storage while aligning with common usage volumes across laboratory settings.
