High-Performance Collection Tubes—Engineered for Precision, Safety, and Ease of Use

Ciro’s centrifuge and collection tubes are designed to support critical applications in molecular biology, clinical chemistry, and biochemistry. Built for comfort and reliability, our tubes combine ergonomic functionality with unmatched durability—making them ideal for sample collection, preparation, storage, and high-speed centrifugation.

Ergonomic, One-Handed Operation

Streamline your workflow with user-friendly design features:

• Secure one-handed opening and closing

• Optimized shape for gloved handling

• Leak-proof seal for safe sample transport and processing

Whether you're working at the bench or in the field, our ergonomic design ensures comfort without compromising sterility or safety.

Superior Material and Performance

Manufactured from ultra-pure, medical-grade polypropylene (PP), our tubes meet stringent regulatory and performance criteria:

• Compliant with FDA 21 CFR 177.1520 and 21 CFR 178.2010

• Free from slip agents, plasticizers, and biocides

• High chemical and mechanical resistance

• Withstands centrifugation up to 30,000 × g

• Functional across -86 °C to 100 °C

• Autoclavable at 121 °C for 20 minutes (open cap)

Each lot undergoes rigorous in-line and final inspection to ensure dimensional precision, mechanical integrity, and batch-to-batch consistency.

Clean and Contamination-Free

For sensitive workflows, our tubes are available in PCR clean formats—DNase, RNase, and pyrogen-free—to protect the integrity of your biological samples.
