Why Strips Curl Assembling lateral flow cards in uncontrolled humidity leads to membrane curling and adhesive failure. Nitrocellulose expands when wet. Ideal Conditions We manufacture Due Bio strips in a Class 100,000 cleanroom maintained at
Width Matters A strip cut at 3.8mm instead of 4.0mm contains 5% less reagent. This directly impacts line intensity and quantification. Rigid Backing Our Universal Strips utilize a high-rigidity PVC backing card that resists “blade drag” during high-speed guillotine cutting, ensuring every strip is mathematically identical.
Adhesive Failure Delamination usually occurs during the cutting process. If the backing card’s adhesive is too weak or too old, the membrane lifts off, disrupting capillary flow. The “Pressure” Factor Ensure your laminator applies consistent pressure (30-50 psi). Furthermore, Due Bio uses a high-tack acrylic adhesive backing that cures over time, providing a permanent bond … Read more

The Nightmare of Lot Variation You validated your assay on Lot A, but Lot B gives false positives. Sound familiar? Variation in nitrocellulose casting thickness is the #1 killer of LFA projects. Our QC Standard Due Bio uses automated reel-to-reel laser inspection to monitor membrane thickness to within ±1 micron. We guarantee Inter-Lot CV < ... Read more
