membraPure systems – experts in water purification and related analysers

Since 1993 we produce water purification systems. We have continuously expanded our activities on the analysers. We are one of the top players in our core markets of water purification, TOC measurement, amino acid analysis and ion chromatography, offering an outstanding level of technology and quality such as EDI, post column derivatization with Ninhydrin and NDIR TOC detection. All our low-maintenance systems enable online service support. We sell our equipment world-wide through a network of distributors and our own sales offices in Beijing/PR China, Kuala Lumpur/Malaysia and Latin America. Our head office and our new production hall is located in Hennigsdorf near Berlin/Germany.

Please contact us if you have any questions about our equipment or its applications. Our services help to keep your systems running smoothly at all times.

Products and services

MembraPure is a german specialist for ultrapure water, online TOC analysis, as well as chromatography (amino acid analytics, ion chromatography). The amino acid analyzer ARACUS based on a modular concept is the ideal instrument for the analysis of amino acids in research, quality control and in the clinical laboratory. It combines innovative technologies with the classic routine analysis of amino acids by post-column derivatisation with ninhydrin. The miniTOC instrument uses the classic flow-through concept for online TOC control. The efficient UV oxidation of organic compounds by the “direct surface” principle in combination with conductivity detection guarantees the high precision of the measured values. Aquinity² ultrapure water systems are equipped with a reverse osmosis (RO) and/or an optional electro-deionisation (EDI) cell to produce deionised water. The systems feature 10l, 35l or 70l storage reservoirs which are filled at a production rate of 10l/h.


It combines innovative technologies with the classical routine analysis of amino acids by the post-column derivatisation with ninhydrine. This produces on the day by day use results with the highest precision, reproducibility and accuracy. The setup of the instrument allows the continuous analy- sis of 96
samples (2x48 vials). The samples are stored in the cooled autosampler and the samples are injected without sample loss.

Aquinity² ultrapure water systems are equipped with a reverse osmosis (RO) and/or an optional electrodeionisation
(EDI) cell to produce deionised water. The systems feature 10l, 35l or 70l storage reservoirs which are filled at a production rate of 10l/h. The deionised water can be dispensed straight from this reservoir. In the next step the ultrapure water is produced with an optimized combination of activated carbon and mixed bed cartridges.

miniTOC new option: degree of protection IP 54

The miniTOC is now also available with the option IP 54 (according to DIN EN 60259).
The degree of protection IP 54 stands for protection against dust deposits inside and for protection against splash water from all directions. This is ensured by the monitor cover, the special fan cover and the covers for the USB and analog connection.
