# Sample Retention Cabinet
## 1. General Overview
Sample Retention Cabinet (also called Retention Sample Cabinet) is a professional storage device designed for the compliant preservation, organization, and traceability of retained samples in industries such as food & beverage, pharmaceuticals, cosmetics, and quality control laboratories. It ensures sample integrity, prevents cross-contamination, and meets regulatory requirements (e.g., GMP, ISO, food safety standards) for sample retention and audit.
## 2. Main Applications
- Food Industry: Retain food samples (meals, ingredients, finished products) for 48–72 hours for food safety inspection and accident traceability.
- Pharmaceutical & Cosmetics: Store batch samples, raw material samples, and finished product samples for quality verification and complaint handling.
- Laboratories & QC Departments: Archive test samples, control samples, and reference samples for long-term preservation and data comparison.
- Hospitals & Canteens: Comply with local food safety regulations for mandatory sample retention.
## 3. Key Construction & Materials
- Body Material: Premium 304 stainless steel, corrosion-resistant, easy to clean, hygienic, suitable for cleanrooms.
- Interior: Adjustable shelves, independent drawers, compartmentalized sections for classified storage; smooth surfaces to avoid cross-contamination.
- Door: Sealed & insulated door with secure lock (mechanical lock, electronic lock optional) to guarantee sample safety and anti-theft management.
- Insulation & Cooling: High-density insulation layer, constant temperature refrigeration system, stable internal temperature to slow down sample deterioration.
## 4. Core Features
- Constant temperature control, intelligent temperature display and over-temperature alarm function.
- Independent separated storage design, effectively isolate different samples and avoid odor mixing.
- Fully sealed structure, dust-proof, moisture-proof, mildew-proof and easy for daily disinfection.
- Low energy consumption, low noise operation, stable and durable for long-time continuous work.
- Humanized design with flexible space layout, convenient for daily access and sample record management.
## 5. Working Principle & Advantage
This cabinet adopts professional constant temperature refrigeration technology to maintain a low-temperature and stable storage environment. Strict physical isolation and sealed storage design standardize sample management, realize full-process traceability of production batches, effectively reduce quality risks, and fully meet industrial production, catering service and laboratory quality management specifications.
