Biochemazone™® Soil Test ASTM F3208-20 is a high-quality, standardized soil formulation specifically designed to meet the requirements of ASTM F3208-20, ensuring accurate and reliable validation of cleaning methods for reusable medical devices. This test soil simulates real-world contaminants encountered during clinical use, providing researchers and manufacturers with a dependable solution for cleaning performance validation.

Key Features:
• Compliance with ASTM Standards: Formulated to adhere to ASTM F3208-20 guidelines, ensuring standardized and reproducible results.
• Simulates Real-World Contaminants: Accurately replicates biological and non-biological soils encountered by reusable medical devices, including human secretions, blood, tissue, bone fragments, bone cement, lubricants, and dyes.
• Optimized Physical Properties: Engineered to match the viscosity, adhesion, and other physical parameters of clinical contaminants for realistic testing.
• Ready-to-Use: Pre-packaged and laboratory-ready, simplifying preparation and ensuring consistent performance.

Depending on the intended medical device application, different test soil formulations may be selected to more accurately simulate clinical conditions:

Coagulating blood test soil – Designed for instruments used in general surgery, orthopaedic, vascular, and similar procedures where blood exposure is expected to coagulate prior to cleaning.

Defibrinated (non-coagulating) blood soil – Intended for devices exposed to blood in the presence of anticoagulants or high irrigation environments where coagulation does not occur.

Mucus-type (British Standard–style) soil – Suitable for instruments used in upper respiratory (ENT) and gastrointestinal endoscopy applications where mucus is the primary contaminant.

Blood + mucus mixed soil – Developed for flexible endoscopes (e.g., GI endoscopes with biopsy capability) that encounter both mucosal secretions and intermittent bleeding. Soil composition can be adjusted to replicate specific clinical scenarios.

Non-patient–derived soils (e.g., bone cement/PMMA, lubricants, dyes) – Used for instruments exposed to procedural materials such as orthopaedic saws and burrs. These may be used individually or in combination with patient-derived soils to better reflect real-world contamination.

Artificial Test Soil (F3208-aligned composite) – A standardized, protein-rich formulation intended for gastrointestinal and other mixed-soil applications where a reproducible and scientifically justified cleaning challenge is required.
