Common Problems in High-Speed Centrifugation
Laboratories running repetitive centrifugation workflows often face three common consumable challenges:
- Tube leakage during high-RCF centrifugation
- Structural deformation or cracking under repeated force cycles
- Sample loss caused by wall adsorption residue
These issues may result in repeated test runs, rotor cross-contamination, wasted valuable biological samples, higher reagent consumption, and lowered experimental reproducibility.
Hawach 50 mL centrifuge tubes are engineered to mitigate such risks for daily lab operations.
Why Hawach 50 mL Centrifuge Tubes Perform Better
1. Leak-Resistant Screw Cap Structure
The optimized threaded cap design preserves sealing performance during high-speed centrifugation and negative-pressure handling.
- Minimizes leakage under 12,000 x goperation
- Lowers potential rotor contamination risks
- Suitable for volatile buffers and biological reagents
- Maintains consistent workflow cleanliness
2. Reinforced Tube Wall for High-RCF Stability
Thickened conical wall structure distributes centrifugal stress evenly during repeated runs.
- Reduces the chance of tube deformation
- Retains stability in pelleting and clarification workflows
- Adapts to continuous high-speed usage
- Compatible with fixed-angle and swing-bucket rotors
3. Low-Retention Inner Surface
Smooth inner wall reduces non-specific adsorption of proteins, nucleic acids, enzymes and biological suspensions.
- Improves recovery of limited-volume samples
- Cuts residual loss after centrifugation
- Enhances result consistency in molecular biology workflows
- Reduces waste of high-cost reagents
4. Broad Chemical Compatibility
Constructed from USP Class VI virgin polypropylene with HDPE screw caps.
Compatible with:Methanol, Acetonitrile, weak acids, weak bases, standard lab buffers, biological suspensions.
Well suited for molecular biology, microbiology, pharmaceutical QC and analytical labs.
5. Wide Temperature Resistance
