Typical applications
Colloidal gold assay development
Materials and equipment for labeling, lateral flow, color development and reading.
R&D sampling
Small-batch prototyping, condition screening and material comparison.
Process validation
Dispensing volume, spraying volume, material combination and strip consistency validation.
Production adoption
Consumables and equipment matched with capacity, strip format and quality requirements.
Selection considerations
| Labeling target | Antibody, antigen or other binders influence particle size, pH, stabilizer and blocking strategy. |
|---|---|
| Strip structure | NC membrane, sample pad, conjugate pad, absorbent pad and backing card jointly determine performance. |
| Production pace | Strip width, cutting precision, spraying repeatability and assembly efficiency shape equipment selection. |
