MEDICA® R and MEDICA® D 7/15

When high purity water is required in low volumes for a single analyzer, the MEDICA-R and -D offer a range of systems at an undemanding cost of ownership.

MEDICA-R and MEDICA-D (7/15) supply a constant flow of high purity water which is maintained by recirculation through ion exchange resins, UV, and an integral 0.2µm microfilter. It is an ideal choice for use with a single chemistry or immunoassay clinical analyzer.

  • Delivers up to 1.8 liters per minute of CLRW standard water (formally CLSI Type 1 water)
  • Provides compliant purified water suitable for a dissolved oxygen specification
  • Compatible with single clinical diagnostic analyzers which require up to 1.8 liters per minute of CLRW standard water
  • A bypass loop for the continual supply of compliant water in emergency situations to the analyzer
  • Low running and consumable costs
  • Compact size makes it suitable to be installed under a bench or mounted on a wall
  • Full service and validation support

MEDICA-R (7/15)

The low-usage option for tap water feed

A compact, dedicated unit providing CLRW grade water, the MEDICA-R is an ideal choice for use with a single chemistry or immunoassay clinical analyzer. Two models are available providing either 7 or 15 liters/hr, and facilitating an instantaneous demand of up to 1.8 liters/min from tap water feed.

MEDICA-D (7/15)

Low-usage option to meet dissolved oxygen specification

The MEDICA-D shares the same features as the MEDICA-R, providing CLRW grade water for single clinical analyzers. In addition, the MEDICA-D incorporates a deaeration membrane, providing a reliable dissolved oxygen specification that is required by some clinical analyzers. This product is also available in two models providing either 7 or 15 liters/hr.



Ideally suited for: 

• Single clinical analyzers requiring up to 7–15 liters/hr 

• Single clinical analyzers requiring up to 1.8 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 difference between a MEDICA R and MEDICA D?

The MEDICA R 7/15 is ELGA's standard product for analysers requiring feedwater volumes of 7-15L/hr. The R stands for recirculating, meaning that the water circulates throughout the purification technologies before it is fed to the analyser ensuring that the quality of water is at the levels required. The MEDICA D has the same recirculating design, however, some analysers have an oxygen specification which is needed to enable them to accurately run their tests. This product removes a % of oxygen from the water to meet these testing requirements.

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.
