LIGHT LABS SureLock™ A-7001-R | 1.7mL Rainbow Assorted Color Microcentrifuge Tubes, Non-Sterile — 500/Bag

The LIGHT LABS SureLock™ A-7001-R (Sorenson BioScience SafeSeal™, manufacturer catalog # 11590) is a 1.7mL SafeSeal™ microcentrifuge tube in assorted rainbow colors — the same positive-seal, high-strength polypropylene construction as the LIGHT LABS A-7001 (natural/clear), now in a vibrant mix of colors for instant visual sample organization and color-coded workflow management. Designed to fit all standard rotors with a 25,000 x g RCF rating and autoclavable. Non-Sterile, Bulk Bag. Certified RNase/DNase Free. Certified Human DNA Free. Certified PCR Inhibitor Free. Certified Pyrogen Free. Supplied in convenient bulk bags of 500 tubes per bag. Graduated. Frosted writing surface. Temperature range: -80°C to 121°C.

Rainbow Colors — Instant Visual Sample Organization The assorted rainbow color mix of the A-7001-R provides a selection of brightly colored tubes — including blue, green, red, violet, and yellow — allowing immediate color-coded organization of multiple experimental conditions, sample sets, patient groups, time points, or reagent preparations across a single experiment or between experiments. Color coding with rainbow microcentrifuge tubes is one of the simplest and most effective contamination-prevention and sample-tracking strategies in molecular biology — when each condition, patient, or reagent has its own color, visual confirmation of correct tube assignment is immediate, intuitive, and requires no labeling. For labs processing dozens to hundreds of tubes per day, the color differentiation of the A-7001-R rainbow assortment directly reduces labeling time, minimizes misidentification errors, and speeds up high-throughput workflows.

A-7001-R vs. A-7001 — Rainbow Assorted vs. Natural: Choosing the Right Format:

SafeSeal™ Positive Seal Design — No Cap Popping During Boiling or Freezing 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, freeze-thaw cycling, and transport. The positive seal design eliminates pressure-induced cap popping in every color in the rainbow assortment — ensuring consistent, reliable sealing performance across all tube colors regardless of experimental conditions.

25,000 × g RCF Rating — High-Speed Centrifugation in Any Color 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 in every color of the assortment — the colorants used in the A-7001-R tube formulations are inert and do not affect mechanical strength, RCF performance, or chemical resistance.

-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 sample storage at -80°C through room temperature processing, boiling, and autoclave sterilization at 121°C — in every color of the rainbow assortment.

Autoclavable — Reusable Under Sterile Conditions Autoclavable. 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 — Easy Labeling in Every Color Graduation lines and frosted writing surface allow visual volume confirmation and provide a dedicated writing area for permanent marker, pencil, or cryogenic label adhesives — supporting good laboratory practice documentation and sample traceability even on colored tubes.

Fits All Standard Rotors Fit all standard rotors. The standard 1.7mL microcentrifuge tube geometry ensures compatibility with all standard microcentrifuge rotors from all major centrifuge manufacturers without adapters or modifications — in every tube color.

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-7001-R for the most demanding molecular biology applications in every color of the assortment — the colorants used are inert and do not contribute nucleases, human DNA, PCR inhibitors, or pyrogens.
