Conical Centrifuge Tubes

# Conical Centrifuge Tubes

ZHCLAB Conical Centrifuge Tubes deliver reliable performance for sample processing and storage across molecular biology, cell culture, and clinical laboratory applications. Available in 10mL, 15mL, and 50mL capacities with multiple closure and bottom configurations to support diverse centrifugation and storage protocols.

## Key Features

Multiple Configuration Options
Available in 10mL, 15mL, and 50mL capacities with round bottom or conical bottom designs. Choose from screw top, screw cap, or self-standing formats to match specific centrifugation workflows and storage requirements.

Certified Quality Standards
– Sterile – Gamma irradiated, ready for immediate use
– DNase/RNase Free – Safe for molecular biology applications
– Pyrogen Free – No endotoxins
– Human DNA Free – No contamination risk

Premium Polypropylene Construction
Manufactured from virgin polypropylene (PP) with high optical clarity for easy sample visualization and liquid level monitoring. Excellent chemical resistance to most laboratory reagents, acids, and bases. Transparent tube body with blue or yellow caps enables color-coded sample organization across multiple experiments.

Secure Closure Systems
Screw-top and screw-cap designs provide leak-resistant sealing during centrifugation and storage applications. Self-standing models offer hands-free stability on benchtops, eliminating the need for separate tube racks during sample processing workflows.

Precision Engineering
– 10mL tubes: 16.5mm diameter, compatible with standard centrifuge rotors
– 15mL tubes: 16.5mm diameter x 117-120mm height, fits all major centrifuge models
– 50mL tubes: 29mm diameter, accommodates larger sample volumes

Centrifugation Performance
Designed for centrifugation applications up to 12,000 x g. Consistent wall thickness and balanced construction ensure reliable performance across standard laboratory centrifuge platforms.

Temperature Range
Suitable for sample storage and processing across the full laboratory temperature range: -80deg C to +121deg C. Autoclavable for repeated sterilization protocols (121deg C for 20 minutes).

Laboratory-Grade Packaging
Tubes packed in resealable bags with clear lot numbers and expiration dates for quality tracking and laboratory compliance. Packaging quantities optimized for laboratory workflows: 100 tubes per pack for 10mL and 15mL sizes, 50 tubes per pack for 50mL size.
