Serosanguinous Drain Fluid (NPWT and Wound Drain Test Fluid) BZ623
Product Code: BZ623
Manufacturer: Biochemazone
Available Pack Sizes: 100 mL, 200 mL, 500 mL, 1 L (5 L on request)
Custom Bulk Quantities Available
Product Overview
Biochemazone Serosanguinous Drain Fluid BZ623 is a pink-red, blood-tinged wound-drainage simulant for testing negative-pressure wound therapy (NPWT) systems, wound drains, collection canisters and absorbent dressings. Serosanguinous fluid – thin exudate mixed with a little blood – is the most common drainage after surgery, and devices have to handle its protein content and viscosity without clogging or leaking.
The fluid contains protein and electrolytes at wound-exudate levels, a thickener to give a slightly higher viscosity than water, and a red colourant in place of blood. It has a pH of about 7.4 (range 7.2–7.6) and contains no blood, so it can be pumped through devices and disposed of as ordinary laboratory waste.
Each batch is prepared with ISO 3696 compliant high-purity water under Biochemazone’s ISO 9001 / GMP quality system and preserved for use in open flow rigs.
Key Features & Benefits
✅ Serosanguinous Appearance – Pink-red, blood-tinged exudate
✅ Protein and Electrolytes – Wound-exudate levels
✅ Slightly Viscous – Realistic flow through tubing and filters
✅ pH About 7.4 (Range 7.2–7.6) – Typical of fresh drainage
✅ Blood-Free – Safe to pump and dispose of
✅ Preserved – Suitable for open flow rigs
✅ Bulk Available – Larger volumes for canister tests
✅ Made in Canada – Manufactured under ISO 9001 / GMP quality systems
Applications
🩹 NPWT & Drain Testing
• Negative-pressure wound therapy pump and canister testing
• Surgical drains and reservoirs
• Tubing, connectors and filter clogging
🧪 Dressing Development
• Absorbency and retention of foam and superabsorbent dressings
• Leakage and strike-through tests
🎓 Training
• Nursing training on drain assessment
• Simulation and moulage
Usage Areas
- NPWT and wound-drain manufacturers
- Wound-dressing developers
- Medical-device test laboratories
- Nursing schools and simulation centres
- Hospital device-evaluation teams
