Essential Consumables and Equipment for Colloidal Gold Rapid Tests
A stable colloidal gold rapid test requires coordinated materials and equipment, including membranes, pads, backing cards, cassettes, striping, spraying, cutting, assembly, sealing and reading systems.
R&D sampling
Focus on antigen/antibody pairing, colloidal gold labeling, NC membrane, sample pad, conjugate pad, absorbent pad, backing card overlap and color development.
Pilot validation
Focus on striping volume, spraying volume, cutting width, cassette assembly, drying, sealing, repeatability and lot consistency.
Production adoption
Focus on throughput, equipment maintenance, consumable specifications, lot documents, packaging, lead time and supply continuity.
FAQ
Is all equipment needed at once?
No. Equipment should match R&D stage, capacity requirement and current facility conditions.
How should backing cards be selected?
Strip width, NC membrane position, overlap distance, cassette structure and dimensions should be considered.
