Microcentrifuge tubes are among the most frequently used consumables in any life sciences laboratory. From DNA extraction to protein purification, these small but essential tubes play a critical role in daily benchwork. Choosing the right microcentrifuge tube — in terms of size, material, and sterility — can directly impact experimental reproducibility.
At JW RESEARCH SUPPLY PTE. LTD., we stock a comprehensive range of microcentrifuge tubes at our Singapore distribution hub, ensuring fast delivery to research institutions, biotech parks, and CRO facilities across the island.
Common Microcentrifuge Tube Sizes
| Size | Typical Capacity | Common Applications |
|---|---|---|
| 0.5 mL | 500 µL | PCR setup, small-volume enzyme reactions |
| 1.5 mL | 1.5 mL | DNA/RNA storage, centrifugation, sample prep |
| 2.0 mL | 2.0 mL | Cell pelleting, bead beating, large-volume reactions |
| 5.0 mL | 5.0 mL | Larger sample prep, gradient centrifugation |
Material: Polypropylene (PP)
Nearly all microcentrifuge tubes are made from virgin polypropylene, which offers excellent chemical resistance, temperature tolerance (−80°C to +121°C), and clarity. High-quality tubes from JWRESEARCH are manufactured from medical-grade PP with no additives that could leach into samples.
Key Features to Consider
- Snap-cap vs Screw-cap: Snap-cap tubes are convenient for quick access; screw-cap tubes provide a tighter seal for long-term storage or hazardous samples.
- Graduations: Printed volume markings help with quick visual estimation.
- Writing Surface: A frosted area allows easy labelling.
- Sterility: Choose DNase/RNase-free, pyrogen-free tubes for molecular biology work.
Applications Across Singapore Labs
Singapore's biomedical ecosystem — from Biopolis research institutes to Tuas manufacturing facilities — relies on high-quality consumables. Microcentrifuge tubes are used daily in:
- Molecular biology (PCR, qPCR, sequencing)
- Protein biochemistry (centrifugation, storage)
- Clinical diagnostics (sample processing)
- Biopharma QC (stability testing)
