Reliable and economical supply for analyzers which require higher volumes of water

Designed to supply CLRW grade water to a single analyzer. The MEDICA EDI 15/30 is the ideal system to provide predictable consumables usage, reducing the number of interventions.

The MEDICA EDI 15/30 is a compact, high-performance water purification system that directly feeds Clinical Diagnostic Analyzers with up to 1.5 l/min of CLRW standard grade water. The MEDICA EDI incorporates EDI ‘Pulse Technology’ using Electrodeionization (EDI). Innovative technology, combined with its unique features, makes the MEDICA EDI 15/30 a highly reliable and cost-effective choice.

  • Space saving design – smallest footprint available on the market for the pure water specification. Optional Docking Vessel water reservoir facilitates bench top or wall mounting as a single unit
  • Guaranteed performance at all times through self-monitoring software, easy system maintenance, and emergency by-pass facility
  • Pure water ready to go – water specification is maintained in the reservoir by regular recirculation through the system’s purification process




Ideally suited for: 

• Single or multiple clinical analyzers requiring up to 30 liters/hr
• Single clinical analyzers requiring up to 1.5 liters/min instantaneous demand of CLRW grade water

Frequently Asked Questions (FAQs)

What is the MEDICA product range?

The MEDICA product range is specifically targeted at the Clinical diagnostics market. The MEDICA will either directly feed (analysers which require a direct feed) or fill via a dispense gun the analyser with water that meets the recommendations of the Clinical Laboratory Standards Institute (CLSI).

What is the MEDICA EDI?

The MEDICA EDI is designed to reduce the running costs associated with purified water purification. This is because the EDI stack removes significant ionic content from the water before the water passes through downstream consumables, lowering the number of consumables which need to be changed.

If it is cheaper to run should I always purchase the MEDICA EDI?

Low quality feedwater with very high ionic content can cause saturation of the EDI stack nullifying its benefits. It is therefore important to ensure that the feedwater is within the product specifications.

What feedwater is required?

Normally potable water is sufficient as feedwater. However, the quality of potable water can vary between countries and regions. Feed water specifications can be found in the operators manual and the data sheet of the product. It is important that if the feedwater specification is exceeded suitable pre-treatment be installed to bring the feedwater within specifications.

How often do I need to change my consumables?

Consumables life depends entirely on the quality and volume of water being fed into the MEDICA product. Higher volumes and lower quality water will increase consumables usage.
