Centrifuge Tubes

# Centrifuge Tubes

ZHCLAB Centrifuge Tubes deliver reliable performance for sample processing, centrifugation, and storage across molecular biology, cell culture, and clinical laboratory applications. Available in capacities from 0.1mL to 100mL with multiple bottom configurations and closure types to support diverse laboratory workflows.

## Key Features

Comprehensive Capacity Range
Complete range of tube sizes from 0.1mL microcentrifuge tubes to 100mL large-volume centrifuge tubes. Available in conical bottom and round bottom designs with various closure options including screw tops, snap caps, and tubes with integrated lids.

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.

Multiple Configuration Options
Choose from conical bottom tubes for efficient pellet formation and complete sample recovery, or round bottom tubes optimized for mixing and resuspension applications. Select tubes with screw tops, integrated snap caps, or separate lids based on specific protocol requirements.

Precision Engineering
Optimized dimensions for compatibility with standard laboratory centrifuge rotors:
– 0.1-0.5mL: Microcentrifuge tube format for PCR and small-volume applications
– 1.5-2.0mL: Standard microcentrifuge tube format
– 5-10mL: Medium-volume format for cell culture and sample preparation
– 15-50mL: Conical tube format for larger sample volumes
– 100mL: Large-volume format for media preparation and bulk processing

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).

Secure Closure Systems
Multiple closure options to match specific applications: screw-top designs for leak-resistant sealing during centrifugation and storage, snap-cap formats for quick access, and integrated lids for self-standing stability on benchtops.

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 across all tube sizes.
