A-4007 | 0.1mL 8-Strip Low-Profile PCR Tubes with Optically-Clear Flat Caps, Clear — 125 Strips/Pack

The LIGHT LABS A-4007 (SSI Bio manufacturer catalog # 3145-00) is a 0.1mL low-profile 8-strip PCR tube with optically-clear flat caps — angularly attached caps on UltraFlux® i and SnapStrip® tubes prevent cap 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. Clear tubes provide high clarity for visualizing contents. Manufactured from high-quality, virgin polypropylene to ensure purity and provide excellent optical clarity. Certified free of detectable RNase, DNase, DNA, and PCR inhibitors. For use in pharmaceutical industry, food industry, and molecular biology. Clear tubes. 125 strips per unit, 10 units per case. Also available in white (A-4007-40 / 3145-40) and in sterile formats.

0.1mL Low-Profile Format — Optimized for qPCR Instruments with Low-Profile Block Positions The 0.1mL tube volume of the A-4007 / 3145-00 is the low-profile PCR tube standard — designed specifically for thermal cyclers equipped with low-profile block positions that require shorter, lower-volume tubes. Low-profile 0.1mL tubes provide tighter, more consistent contact between the tube wall and the thermal cycler block compared to standard 0.2mL tubes in low-profile block positions — resulting in more efficient thermal transfer, faster temperature equilibration, and more consistent well-to-well cycling performance. For labs running qPCR on instruments with dedicated low-profile block positions, the A-4007 / 3145-00 is the correct tube format — and using standard 0.2mL tubes in low-profile positions can result in poor block contact and compromised thermal cycling performance.

A-4007 vs. A-4004 — 0.1mL Low-Profile vs. 0.2mL Standard: Choosing the Right Tube:

Angularly Attached Caps — Designed for SBS Format Rack Operation Angularly attached caps on UltraFlux® i and SnapStrip® tubes prevent cap lids and hinges from interfering with each other, allowing for easier operation in an SBS format rack. The angular cap attachment is one of SSI Bio's patented design innovations — by attaching the cap at an angle rather than perpendicular to the tube, the cap lid and hinge clear each other completely when the cap is open, eliminating the interference between adjacent open caps that makes standard perpendicular-hinge strip tubes difficult to operate in the tight confines of a standard SBS format rack. For high-throughput labs running 8-strip tubes in SBS racks on robotic platforms or benchtop workstations, the angular cap design dramatically improves pipetting access and workflow speed.

Optically-Clear Flat Caps — Ideal for qPCR Fluorescence Detection The optically-clear flat cap design of the A-4007 / 3145-00 is specifically optimized for real-time qPCR fluorescence detection — the flat cap geometry provides a uniform, distortion-free optical surface directly above the reaction well for consistent fluorescence measurement by the qPCR instrument's detection system. The clear cap provides the highest possible light transmission from the instrument excitation source and to the detector — essential for accurate, reproducible quantification in real-time PCR applications.

Ultra-Thin Walls — Efficient Thermal Transfer for Consistent PCR Results Ultra-thin walls ensure efficient thermal transfer and maximum yield, yet are strong enough to prevent crushing. The ultra-thin wall construction minimizes thermal resistance between the cycler block and the PCR reaction — allowing the reaction to closely follow programmed cycling temperatures during denaturation, annealing, and extension. In the 0.1mL low-profile format, the shorter tube height combined with ultra-thin walls provides some of the fastest thermal equilibration of any PCR tube format — critical for high-resolution melting (HRM) and other applications where precise temperature control is essential.

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. The virgin polypropylene construction ensures freedom from recycled resin contaminants and processing aids that could inhibit PCR or introduce false signals in sensitive downstream analysis.

Certified Purity — Full PCR Qualification Panel Certified free of detectable RNase, DNase, DNA, PCR inhibitors, and tested pyrogen-free. The complete purity certification qualifies the A-4007 / 3145-00 for all standard PCR, RT-PCR, and qPCR applications — including sensitive RNA workflows, single-copy DNA amplification, and clinical or regulated molecular biology applications.

Manufactured in the USA — ISO 9001:2015 Quality Assurance SSI Bio products are manufactured in Lodi, California with 1,500 square meters meeting or exceeding ISO 8 / Class 100,000 cleanroom standards under an ISO-9001:2015 quality assurance system. Made in the USA — a meaningful distinction from overseas PCR tube manufacturers.
