FSTest InstaPro Swab
Rapid Surface Protein Residue Detection for Hygiene Verification
The FSTest InstaPro Swab is a rapid, ready-to-use surface hygiene monitoring solution designed for the detection of trace protein residues after cleaning.
By delivering a simple visual indication of surface cleanliness, it helps verify sanitation effectiveness, reduce cross-contamination risks, and support routine hygiene monitoring within HACCP-based food safety programs.
Suitable for food production, commercial kitchens, and industrial sanitation environments, the InstaPro Swab enables fast decision-making without laboratory equipment.
Why Test Surface Protein Residues?
Protein residues are widely recognized as an important indicator of incomplete cleaning and potential contamination risks.
Undetected residues may lead to:
- Cross-contamination between production batches
- Reduced cleaning effectiveness
- Increased food safety risks
- Non-compliance with sanitation procedures
Routine verification helps maintain cleaning standards and strengthen preventive food safety controls.
Key Features & Benefits
- Rapid Visual Results: Most positive reactions appear within 60 seconds, with final confirmation completed within 10 minutes at room temperature (15–25°C)
- High Sensitivity:Detects as low as 20 μg protein within 10 minutes at room temperature, or 10 μg within 1 minute at 40°C
- Ready-to-Use Format: Pre-moistened swab and integrated reagent system require no additional equipment
- Easy Interpretation: Clear color transition enables fast pass/fail assessment without specialized training
- Improved Hygiene Verification: Supports sanitation validation and routine environmental monitoring
- Eco-Friendly Design: Manufactured using recyclable plastic materials

Simple 4-Step Testing Workflow
Step 1 – Sample Collection
Swab approximately 10 × 10 cm of the target surface using a cross-hatch pattern while rotating the swab tip.
Step 2 – Activate the Device
Return the swab into the tube and activate the SnapValve to release the reagent.
Step 3 – Mix & React
Squeeze the tube twice, wait 15 seconds, then shake for 5–10 seconds.
Step 4 – Read Results
Allow reaction at 15–25°C for up to 10 minutes and compare the final color with the reference chart.
Result Interpretation
-
Light Green — Pass
Surface is considered clean and hygienic. -
Grey / Light Purple — Caution
Trace protein residue detected. Additional rinsing or verification may be required. -
Light Purple / Dark Purple — Fail
Significant protein residue detected. Re-cleaning and re-testing are recommended.
