Formaldehyde Rapid Test Kit
Brand: FSTest
3–5 mins Rapid Visual Result | 5 mg/kg High Sensitivity (LOD) | Color Chart Visual Comparison | Field Ready Zero Equipment Needed |
The FSTest Formaldehyde Rapid Test Kit is a fast, accurate, and instrument-free colorimetric detection kit designed for on-site qualitative and semi-quantitative screening of illegal formaldehyde addition in seafood, soaked aquatic products, dried foods, and mushrooms.
Formaldehyde is a toxic chemical sometimes illegally used as a preservative or bleaching agent to extend shelf life and improve appearance. Based on specific colorimetric reaction chemistry, the FSTest Formaldehyde Test Kit produces a distinct color change (ranging from light purple/pink to deep purple) in proportion to formaldehyde concentration within 3 to 5 minutes, providing market inspectors and food processors with immediate Pass/Fail answers.
Rapid 3-Minute Result: Delivers fast visual color development in 3 to 5 minutes for immediate decision-making at seafood wholesale markets.
High Detection Sensitivity: Detects trace formaldehyde contamination down to 5 mg/kg (ppm), catching illegal soaking early.
Easy Visual Interpretation: Includes a calibrated color card for quick semi-quantitative concentration estimation without requiring expensive laboratory instruments.
Complete Ready-to-Use Kit: Packaged with pre-measured extraction buffers, droppers, and reaction tubes for convenient field operation.
Cost-Effective Screening: Significantly lowers routine inspection costs compared to HPLC or spectrophotometric laboratory methods.
