0.65mL Format — The Compact Standard for Small-Volume Molecular Biology The 0.65mL microcentrifuge tube format is the compact standard for small-volume reactions, enzyme assays, primer storage, reagent aliquoting, and any workflow where the larger 1.7mL format would leave excess unused tube volume. At 0.65mL capacity the A-7002 is ideal for:

• Enzyme and restriction digest reactions at 10–50µL scale where small reaction volumes must be concentrated at the tube bottom during brief centrifugation
• Primer and oligonucleotide storage at small volumes where minimizing headspace reduces freeze-thaw oxidation and evaporative concentration
• Small-volume sample dilutions and serial dilutions requiring precision at low volumes
• PCR reagent preparation and master mix aliquoting at small scale before transfer to PCR tubes or plates
• Short-term sample storage where the compact tube footprint maximizes rack and benchtop space efficiency
• Fluorometric and colorimetric assays at small reaction volumes requiring compact tube geometry for consistent pipetting

A-7002 vs. A-7002-Z — Natural vs. Rainbow Assorted: Choosing the Right Color Format: The A-7002 and A-7002-Z are identical in construction, performance, and specifications — the tube color is the sole differentiator:

The A-7002 natural clear format is the preferred choice for labs that rely on visual inspection of tube contents — including monitoring reaction color, checking for precipitation, and confirming pellet formation — where colored tube walls would obscure observation. For labs requiring color-coded sample organization across multiple conditions, the A-7002-Z rainbow assorted format provides the same tube in multiple colors.

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

SafeSeal™ Positive Seal Design — No Cap Popping During Boiling or Freezing Positive seal design allows for repeated cap closures and eliminates pressure induced popping of caps. 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. At 0.65mL scale where small sample volumes are especially vulnerable to loss from cap failures during boiling or heating steps, the positive seal design is a critical safety feature that protects precious small-volume reactions.

25,000 × g RCF Rating — High-Speed Centrifugation Performance Superior strength — RCF rating of 25,000 x g. 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 (typically 16,000–21,000 × g) — providing a meaningful safety margin for all standard centrifugation protocols.

-80°C to 121°C Temperature Range — From Freezer to Autoclave Temperature rating from -80°C to 121°C. 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 — all in a single tube format without requiring format changes between workflow stages.

Autoclavable — Reusable Under Sterile Conditions Autoclavable. The polypropylene construction and SafeSeal™ cap both withstand autoclave sterilization at 121°C — allowing the A-7002 to be re-sterilized for regulated or aseptic applications requiring sterilization before use.

Natural Color — Optical Clarity for Visual Sample Inspection The natural (clear) polypropylene construction of the A-7002 allows direct visual inspection of tube contents at all stages of the workflow — monitoring reaction color changes, confirming pellet formation after centrifugation, checking for precipitation or phase separation, and verifying sample loading before capping. For small-volume reactions at 0.65mL scale where contents must be monitored carefully, the optical clarity of natural polypropylene is a meaningful practical advantage over colored tube formats.

Graduated with Frosted Writing Surface — Accurate Volume Reference and Easy Labeling Graduation lines allow visual volume confirmation at 0.65mL scale and the frosted writing surface provides a dedicated labeling area for permanent marker, pencil, or cryogenic label adhesives — supporting good laboratory practice documentation and sample traceability throughout freeze-thaw storage and processing cycles.

Fits All Standard Rotors Fit all standard rotors. The standard 0.65mL microcentrifuge tube geometry ensures compatibility with all standard microcentrifuge rotors from all major centrifuge manufacturers without adapters or rotor modifications.

Full Molecular Biology Certification — Four-Panel Purity Assurance 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 for the most demanding molecular biology applications including RNA isolation, PCR setup, enzyme assays, and any workflow where tube material contamination could affect results or compromise data integrity.
