Centrifuge Bottles (Polypropylene, Conical, Plug-Sealed Cap)
Shop high-performance polypropylene (PP) centrifuge bottles designed for high-volume centrifugation in research and QC laboratories. These conical centrifuge bottles feature a plug-sealed, leak-resistant cap and are built for reliable workflows up to 6,000 × g (model-dependent).
Use this collection to quickly choose the right capacity for your workflow—cell harvesting, sample pelleting, protein precipitation, or bulk sample processing—while keeping your setup consistent across volumes.
Quick Pick: Choose by Capacity
-
250 mL Centrifuge Bottles – compact high-volume option for routine processing (View 250 mL)
-
500 mL Centrifuge Bottles – large-volume choice for higher throughput runs (View 500 mL)
What makes these centrifuge bottles different?
-
Plug-sealed cap helps reduce leaks, spills, and evaporation during centrifugation and handling
-
Conical bottom supports efficient pelleting and easier sample recovery
-
Polypropylene (PP) provides chemical resistance and dependable lab durability
-
High-volume formats streamline bulk sample processing with consistent labware
How to Choose the Right Centrifuge Bottle
Most users pick capacity based on sample volume and rotor availability. If you routinely split samples across multiple bottles, choose the capacity that minimizes transfers while staying within your centrifuge rotor limits.
-
Choose 250 mL if you want easier handling, smaller batches, or more flexible balancing.
-
Choose 500 mL if you need higher throughput, fewer transfers, and larger batch processing.
-
Always confirm rotor compatibility for bottle size and maximum RCF before centrifugation.
Collection Highlights
Leak-Resistant Plug-Sealed Cap
A plug-sealed closure helps improve containment during high-volume centrifugation. This reduces the risk of spills, sample loss, and cross-contamination in routine and preparative workflows.
Conical Bottom for Efficient Separation
The conical geometry supports efficient pelleting and simplifies recovery of cells, precipitates, or other solids, improving workflow efficiency for high-volume sample processing.
Polypropylene (PP) for Laboratory Durability
Polypropylene centrifuge bottles are widely used for their chemical resistance and practical lab performance, supporting common biological and analytical protocols.

FAQ
Are these centrifuge bottles compatible with my centrifuge?
These bottles are designed for bench-top centrifuges with appropriate rotors. Always confirm your rotor/bucket compatibility for the bottle size and maximum RCF before use.
What does “plug-sealed cap” mean?
A plug-sealed cap includes an internal sealing feature that helps improve containment during centrifugation and handling, supporting a more leak-resistant workflow.
What are conical bottom centrifuge bottles used for?
A conical bottom supports efficient pelleting and makes it easier to recover cells or precipitates after centrifugation, especially in high-volume sample processing.
Which size should I choose: 250 mL or 500 mL?
Choose 250 mL for routine batches and easier handling, or 500 mL for higher throughput and fewer transfers. Capacity choice should also match your rotor/bucket configuration.
