UltraFlux® i A-4006-Z | 0.2mL 8-Strip PCR Tubes with Optically-Clear Flat Angularly Attached Caps, Assorted Colors — 120 Strips/Pack

Product Description

The LIGHT LABS A-4006-Z (SSI Bio UltraFlux® i, manufacturer catalog # 3247-09) is a 0.2mL 8-strip PCR tube with optically-clear flat angularly attached caps in assorted tube colors — the same proven UltraFlux® i Flex-Free design as the A-4006 (3247-00 Clear) with the added benefit of color-coded tube strips for immediate visual identification of multiple samples, conditions, or time points across a single experiment. Robust inter-well linkages make the strips rigid and easy to handle, preventing spills. Angularly-attached caps prevent lids and hinges from interfering with each other, allowing for easier operation in an SBS format rack. Ultra-thin walls ensure efficient thermal transfer and maximum yield, yet are strong enough to prevent crushing. Manufactured from high-quality, virgin polypropylene to ensure purity and provide excellent optical clarity. Certified free of detectable RNase, DNase, DNA, and PCR inhibitors. 120 strips per unit, 10 units per case.

A-4006-Z vs. A-4006 — Assorted vs. Clear: Choosing the Right Color Format: The A-4006-Z and A-4006 are identical in construction, design, and performance — the tube color is the sole differentiator:

Assorted Colors — Instant Visual Sample Organization The assorted color format of the A-4006-Z provides a mix of colored tube strips — 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 within a single PCR run. For high-throughput PCR workflows where multiple strip tubes are in active use simultaneously, color coding is one of the most practical and immediate contamination-prevention strategies available — when each condition has its own color, visual confirmation of correct tube assignment before thermal cycler loading requires no labeling, no marker, and no checking of written records. The optically-clear caps on all assorted-color strips maintain consistent, unobstructed qPCR fluorescence detection regardless of tube body color.

UltraFlux® i Flex-Free Strip Design — Rigidity Matters Even More with Assorted Colors Robust inter-well linkages make the strips rigid and easy to handle, preventing spills. In assorted-color workflows where multiple strips of different colors are in use simultaneously at the bench, the Flex-Free rigid construction of the UltraFlux® i is especially valuable — a rigid strip is less likely to tip over or flex unexpectedly when set down during multi-strip handling operations. The rigid inter-well linkages ensure that every color-coded strip behaves as a single stable unit, making simultaneous management of multiple colored strips at the biosafety cabinet significantly safer than with flexible standard strip tubes.

Patented Angular Cap Attachment — SBS Format Rack Operation Angularly-attached caps prevent lids and hinges from interfering with each other, allowing for easier operation in an SBS format rack. For assorted-color workflows where multiple strips of different colors are in use simultaneously in SBS format racks, the angular cap design is especially important — it eliminates the interference between adjacent open caps that makes standard perpendicular-hinge strip tubes frustrating to operate in tight rack conditions, regardless of the number of different-colored strips in use.

Optically-Clear Flat Caps — qPCR Compatible Regardless of Tube Color Despite the colored tube bodies, the caps on all A-4006-Z / 3247-09 strips are optically clear — providing a distortion-free optical surface for qPCR fluorescence detection from above. The colored tube body does not interfere with fluorescence reading through the clear cap, making the A-4006-Z fully compatible with real-time qPCR detection on all standard instruments from Bio-Rad, Applied Biosystems, Roche, and other major manufacturers.

Ultra-Thin Walls — Consistent Thermal Transfer Across All Colors Ultra-thin walls ensure efficient thermal transfer and maximum yield, yet are strong enough to prevent crushing. The uniform thin-wall construction delivers consistent, efficient thermal transfer between the cycler block and the PCR reaction in every tube of every strip — regardless of tube color. The colorants used in the assorted tube formulations are inert and do not affect wall thickness, thermal conductivity, or reaction performance.

High-Clarity Virgin Polypropylene — FDA 21 CFR 177.1520 / USP Class VI Manufactured from high-quality, virgin polypropylene to ensure purity and provide excellent optical clarity. Certified free of detectable RNase, DNase, DNA, and PCR inhibitors. SSIbio uses high-clarity, ultra-pure polypropylene that meets FDA 21 CFR 177.1520 and USP Class VI. All colorants used in the A-4006-Z tube strips are inert and do not leach into reaction contents or contribute PCR inhibitors.
