LIGHT LABS SureLock™ A-7002-Z | 0.65mL Rainbow Assorted Color Microcentrifuge Tubes, Non-Sterile — 1,000/Bag

Product Description

The LIGHT LABS SureLock™ A-7002-Z (Sorenson BioScience SafeSeal™, manufacturer catalog # 11210-E) is a 0.65mL SafeSeal™ microcentrifuge tube in assorted rainbow colors — a vibrant mix of colors for instant visual sample organization and color-coded workflow management in the compact 0.65mL format. SafeSeal Microcentrifuge Tube, 0.65mL, assorted color, non-sterile, bulk bag, 1,000 tubes per bag. Certified RNase/DNase Free. Certified Human DNA Free. Certified PCR Inhibitor Free. Certified Pyrogen Free. The 0.65mL format is the compact microcentrifuge tube standard for small-volume reactions, enzyme assays, and sample storage where the larger 1.7mL format would result in excess unused tube volume. Graduated. Frosted writing surface. Fits all standard microcentrifuge rotors. Temperature range: -80°C to 121°C. 1,000 tubes per bag.

0.65mL Format — The Compact Standard for Small-Volume Work The 0.65mL microcentrifuge tube format occupies an important and distinct niche from the standard 1.7mL format — providing just the right volume for small-volume reactions, enzyme assays, primer storage, sample dilutions, and any workflow where the 1.7mL tube would leave the majority of tube volume empty and wasted. At 0.65mL capacity, these tubes are ideal for:

• Enzyme and restriction digest reactions at 10–50µL scale where small reaction volumes must be kept together at the tube bottom
• Primer and oligo storage at small volumes where minimizing headspace reduces freeze-thaw degradation
• Small-volume sample dilutions and reagent aliquots where precision at low volumes is critical
• PCR reagent preparation and master mix aliquoting at small scale
• Short-term sample storage where the compact tube footprint maximizes rack and storage space efficiency

A-7002-Z vs. A-7001-R — 0.65mL vs. 1.7mL Rainbow: Choosing the Right Volume:

Rainbow Colors — Instant Visual Sample Organization at Small Scale The assorted rainbow color mix of the A-7002-Z provides a selection of brightly colored tubes — including blue, green, red, violet, and yellow — allowing immediate color-coded organization of multiple small-volume experimental conditions, enzyme reactions, sample sets, or reagent aliquots. In small-volume workflows where multiple 0.65mL tubes are in use simultaneously on the bench, color coding is especially valuable — the compact tube format makes visual differentiation between tubes more difficult than with larger formats, and color coding eliminates the need for marker labeling on small tube surfaces where legible writing is challenging. The optically clear caps on rainbow-color tubes allow visual inspection of reaction contents despite the colored tube body.

SafeSeal™ Positive Seal Design — No Cap Popping at Any Volume The SafeSeal™ cap mechanism creates a positive mechanical engagement between cap and tube — maintaining a secure, leak-proof seal during high-speed centrifugation, vortexing, boiling, and freeze-thaw cycling in every color of the rainbow assortment. The positive seal design eliminates pressure-induced cap popping — particularly important at 0.65mL scale where small sample volumes are especially vulnerable to loss from cap failures during boiling or heating steps.

25,000 × g RCF Rating — High-Speed Performance in Every Color The robust polypropylene construction maintains tube geometry and cap seal integrity across the full rated centrifugal force range — well above the maximum speed of standard laboratory microcentrifuges — in every color of the rainbow assortment. The colorants are inert and do not affect mechanical strength, RCF performance, or chemical resistance.

-80°C to 121°C Temperature Range — From Freezer to Autoclave The wide temperature range covers every laboratory temperature condition from ultra-low temperature primer and oligo storage at -80°C through room temperature processing, boiling, and autoclave sterilization at 121°C — in every color of the assortment.

Autoclavable — Reusable Under Sterile Conditions The polypropylene construction and SafeSeal™ cap withstand autoclave sterilization at 121°C across all assorted colors — allowing tubes to be re-sterilized for regulated or aseptic applications.

Graduated with Frosted Writing Surface Graduation lines allow visual volume confirmation and the frosted writing surface provides a dedicated area for permanent marker identification — supporting sample traceability even on colored tubes with limited writing surface area at 0.65mL scale.

Full Molecular Biology Certification Certified RNase/DNase Free. Certified Human DNA Free. Certified PCR Inhibitor Free. Certified Pyrogen Free. The complete four-certification purity panel qualifies the A-7002-Z for the most demanding molecular biology applications — the colorants used are inert and do not contribute nucleases, human DNA, PCR inhibitors, or pyrogens.
