Microcentrifuge Tubes Clear Polypropylene 0.5ml 1.5ml 2ml - Snap Cap Conical Bottom NonSterile Lab Tubes

Premium Laboratory Microcentrifuge Tubes for Precision Sample Processing

Achieve reliable, contamination-free results in your laboratory work with these professional-grade microcentrifuge tubes. Engineered for demanding research, clinical diagnostics, and laboratory applications, these versatile tubes deliver exceptional performance across a wide range of centrifugation protocols and sample storage requirements.

Crystal-Clear Polypropylene Construction for Optimal Visibility

Manufactured from naturally colored, clear polypropylene material, these microcentrifuge tubes provide an unobstructed view of your sample contents at all times. The transparent construction allows researchers and technicians to visually monitor samples without opening the tube, reducing contamination risks. The clarity of the polypropylene won't hinder spectrophotometer readings, ensuring accurate optical density measurements and UV-Vis spectroscopy analysis without the need to transfer samples to separate cuvettes.

Precision Graduations for Accurate Volume Measurement

Each tube features large, black, clearly printed graduation marks in precise increments of 0.1 mL, enabling accurate volume measurements and sample tracking throughout your workflow. The high-contrast black markings remain legible even after repeated handling, autoclaving, and exposure to various laboratory conditions. This precision measurement capability is essential for protocols requiring exact sample volumes and for maintaining consistency across experimental replicates.

Convenient Labeling and Sample Identification

A frosted writing area on each tube provides a dedicated space for clear, permanent labeling using standard laboratory markers. This essential feature ensures proper sample identification, prevents mix-ups, and maintains chain of custody in clinical and research settings. The frosted surface accepts ink readily and resists smudging, even when exposed to moisture or handling with gloved hands.

Innovative Snap Cap Design for Safety and Convenience

The permanently attached snap cap features an ingenious thin membrane design that allows trouble-free needle piercing for sample addition or extraction without removing the cap. This innovative design significantly reduces the risks of spills, aerosol generation, and cross-contamination during sample handling. The secure snap closure provides an audible and tactile confirmation of proper sealing, while the attached design eliminates the possibility of cap loss during processing and storage.

Exceptional Temperature Resistance

The robust polypropylene construction withstands an impressive temperature range from -80°C to 121°C (-112°F to 250°F), making these tubes suitable for diverse applications including cryogenic storage, heat inactivation protocols, and autoclave sterilization. This thermal stability ensures sample integrity across freeze-thaw cycles and allows for flexible experimental design without concerns about tube degradation or deformation.

Universal Centrifuge Compatibility and High-Speed Performance

Designed for universal compatibility, these microcentrifuge tubes work seamlessly with all standard and high-capacity centrifuge rotors from major manufacturers. The precision-molded conical bottom design ensures optimal sample recovery and efficient pelleting during centrifugation. These tubes can be safely centrifuged at speeds up to 20,000 RCF (relative centrifugal force), accommodating high-speed applications such as nucleic acid precipitation, protein pelleting, and cellular debris removal.

Certified Contamination-Free Quality

Manufactured from food-grade polypropylene and certified to be completely free from DNase, RNase, pyrogen, and DNA contamination, these tubes provide the purity essential for sensitive molecular biology applications. This certification ensures that your PCR, RT-PCR, sequencing, and other nucleic acid-based assays won't be compromised by enzymatic degradation or contaminating nucleic acids. The quality assurance extends to protein work, cell culture, and other applications where contamination could invalidate results.

Convenient, Secure Packaging

Supplied in resealable, tamper-evident, self-standing bags containing 500 tubes each, with 20 bags per case for a total of 10,000 tubes. The innovative packaging design protects tube sterility and cleanliness during storage while allowing easy access to the quantity you need. The self-standing bags optimize bench space and the resealable closure maintains product integrity between uses. The tamper-evident feature provides assurance that your tubes haven't been compromised prior to use.

Latex-Free for Sensitive Environments

Not manufactured with natural rubber latex, these tubes are safe for use in latex-sensitive environments and won't trigger allergic reactions in sensitive individuals. This makes them ideal for clinical laboratories, healthcare facilities, and research institutions with latex-free policies.

Available in Multiple Volumes

Choose from three convenient sizes to match your application requirements: 0.5 mL for small-volume samples and precious reagents, 1.5 mL for standard molecular biology protocols, or 2 mL for larger sample volumes and extended storage needs. All sizes share the same quality construction and performance characteristics.
