In modern clinical laboratories, water purity is not just important—it is essential. Whether it’s chemistry analyzers, immunoassays, or high-precision testing, even a small contamination can lead to inaccurate results.
The MEDICA R and D 7/15 Systems are designed to meet these demanding requirements, providing reliable, high-purity water for labs that need consistent performance and compliance with CLRW standards.
This article explores how these systems work, their key benefits, and why they are considered the gold standard in clinical laboratory water purification.
What Are MEDICA R and D 7/15 Systems?
The MEDICA R and D 7/15 are high-performance water purification systems specifically designed for clinical diagnostics. They provide CLRW-compliant (Clinical Laboratory Reagent Water) Type I water with a flow rate of either 7.5 or 15 liters per hour, depending on the model.
These systems are suitable for labs operating multiple analyzers or those that require a direct feed system with minimal maintenance.
Key Features and Specifications
Below is a comparison table to help you understand the core differences and capabilities of MEDICA R vs MEDICA D:
| Feature | MEDICA R 7/15 | MEDICA D 7/15 |
|---|---|---|
| Water Flow Rate | 7.5 or 15 liters per hour | 7.5 or 15 liters per hour |
| Water Type Output | CLRW (Type I) | CLRW (Type I) + Dissolved Oxygen Control |
| Dissolved Oxygen Removal | Not included | Included (via deaeration membrane) |
| Bacteria Level | < 1 CFU/ml | < 1 CFU/ml |
| Organic Carbon (TOC) | < 30 ppb | < 30 ppb |
| Final Microfiltration | 0.2 µm filter | 0.2 µm filter |
| Footprint | Compact, bench or wall-mountable | Compact, bench or wall-mountable |
| Usage | Standard lab analyzers | Oxygen-sensitive analyzers |
Why Water Purity Matters in Clinical Labs
High-purity water is the foundation of reliable lab results. Contaminated water can affect:
- Test precision and repeatability
- Reagent life and efficiency
- Sensitivity of detection in immunoassays
- Patient diagnostics and medical decisions
The MEDICA 7/15 Series ensures that water quality stays within safe, validated limits, helping labs maintain ISO and GMP compliance.
How MEDICA Systems Purify Water
The MEDICA R and D systems use a combination of advanced purification techniques:
- Pre-Treatment Filters: Remove large particles and chlorine
- Reverse Osmosis (RO): Removes up to 98% of ions and organics
- Deionization: Ensures high resistivity of water (>10 MΩ·cm)
- UV Oxidation: Breaks down organics at a molecular level
- Final Filtration: A 0.2 µm microfilter ensures sterile output
- Deaeration Membrane (D models only): Removes dissolved gases like oxygen
This layered purification approach guarantees lab-grade, bacteria-free water at all times.
Use Cases: Where Are These Systems Used?
The MEDICA 7/15 systems are ideal for:
- Clinical chemistry and immunology labs
- Automated analyzers that require Type I water
- Labs using oxygen-sensitive processes
- Small to medium-sized hospitals and diagnostic centers
Installation and Operation
The system is plug-and-play for most labs. It connects directly to the mains water supply and automatically manages water purification and reservoir filling.
Real-time monitoring ensures everything runs smoothly, while maintenance is minimal thanks to long-lasting consumables and easily accessible components.
Benefits of Using MEDICA R and D Systems
Here are the top reasons why lab professionals choose the MEDICA 7/15 Series:
1. Reliable Purity Output
The system consistently delivers water that meets CLRW standards for purity, bacteria levels, TOC, and resistivity.
2. Low Maintenance
With automatic sanitization features and clear visual alerts, lab staff can focus on testing rather than equipment upkeep.
3. Compact Design
Fits conveniently under a bench or can be wall-mounted, saving space in busy laboratories.
4. Smart Monitoring
On-screen diagnostics help track filter life, UV status, and water quality in real time.
5. Custom Models for Every Lab
The “R” series is ideal for standard lab needs, while the “D” model is made for analyzers that need low dissolved oxygen.
CLRW Compliance and Safety
MEDICA R and D systems strictly adhere to Clinical Laboratory Reagent Water (CLRW) standards. This ensures:
- Accurate patient results
- Compatibility with sensitive analyzers
- Full audit readiness for laboratory inspections
The D models go a step further by controlling dissolved oxygen levels, meeting the requirements of analyzers that are highly oxygen-sensitive.
Conclusion
The MEDICA R and D 7/15 Systems represent the perfect blend of performance, purity, and practicality for clinical laboratories. With unmatched water quality, low maintenance, and compliance with industry standards, these systems provide a long-term solution to ensure diagnostic accuracy.
Whether your lab needs basic CLRW water or oxygen-sensitive applications, there is a MEDICA model designed for you. Investing in this system means investing in precision, safety, and peace of mind.FAQs
What is the difference between MEDICA R and D systems?
MEDICA R provides CLRW standard water. MEDICA D offers the same purity but also controls dissolved oxygen levels, making it suitable for oxygen-sensitive analyzers.
Can this system supply multiple analyzers?
Yes. Both R and D models can support multiple analyzers simultaneously thanks to their flow rate and constant pressure delivery.
How often do the filters need replacement?
Filter replacement depends on feedwater quality and system usage. The system provides alerts when replacement is needed.
Is it suitable for high-throughput labs?
Yes. With 7.5 or 15 liters per hour capacity and instant dispensing of up to 1.8 L/min, it can handle moderate to high workloads efficiently.
