Whether as a tabletop device, under-counter version, or wall-mounted: membraPure offers numerous variants that integrate seamlessly into any laboratory infrastructure, making everyday laboratory life a little more friendly and pleasant.
Technical intelligence that thinks for itself
What distinguishes membraPure systems is not just the values ​​on the data sheet, but also the detailed solutions. The name endings Reagent, Analytical, or Life Science directly reflect the corresponding application area, providing customers with the right guidance when selecting a system.
Whether integrated TOC sensors, intuitive touch displays, or coordinated filter modules, every feature is designed to simplify processes and utilize laboratory time efficiently.
Support that does more
An ultrapure water system is only as good as the support behind it. membraPure supports users worldwide with personalized service, customized training, and comprehensive resources – directly or through certified specialist dealers.
We offer various models.
The ultrapure water systems are tailored to the different requirements of the
corresponding applications:
To save valuable countertop space, the system can be ordered as a Bench-Integrated (BI) version. The main unit is installed under the workbench, while the display for monitoring parameters and the flexible dispenser for dispensing purified water are mounted on the wall.
If permanent access to data and controls is not required, the BI panel can also be omitted to reduce costs.
The advantage of the panel is its flexible positioning, which does not have to be in direct proximity to the system.
If there is insufficient space on or under the workbench, the system can also be ordered in a wall-mounted version. Depending on the model, both the main unit and the external tank can be securely mounted to the wall. The dispenser is also wall-mounted for convenient handling.
For improved usability, the display can be integrated either at an angle at the bottom or mounted as a standalone BI panel. This ensures the control system remains easily accessible at all times, regardless of the installation height.
Whether you are planning a new ultrapure water system or want to optimize existing systems: The membraPure team will advise you competently, personally, and solution-oriented.
This option allows all systems equipped with a water dispenser to implement volumetrically controlled dispensing of water in 0.1 L increments and a dispensing volume of 0.1 to 99 L. The system prevents containers from overflowing and allows unattended dispensing of water.
This option is not included as standard.
During water production and at defined rest intervals, the system monitors the total organic carbon (TOC) content. The measurement range is between 1 and 999 ppb.
The current values ​​are displayed directly on the screen, allowing for reliable monitoring of potential organic contaminants.
This option is not included as standard and requires an integrated UV lamp, which is only available in the Analytical and Life Science configurations.
The μS control is limited to use in our Astacus² series. It checks the conductivity of the feed water to protect the ultrapure water cartridge from poor-quality feed water. If the feed water conductivity is too high, the water is discarded and cannot affect the quality of the ultrapure water. This prevents the ultrapure water cartridge from becoming depleted too quickly.
The “Direct Feed” modification replaces the dispenser with a direct feed to a technical consumer. This allows water of the highest possible purity to be delivered to the consumer without intermediate storage.
The flow is automatically regulated via an integrated pressure switch.
Consumers requiring Type I or Type II laboratory water are typically analytical instruments or electrolyzers.
Systems can be retrofitted with a dispenser through an upgrade. This applies to the AquaRO² and EDI systems, which are typically designed to produce into an external tank and then receive the product from there.
Support that goes above and beyond
An ultrapure water system is only as good as the support behind it.
Our pure and ultrapure water systems are characterized by low operating costs and minimal maintenance. The latter can be carried out by the customer themselves.
We offer assembly, installation, and training as a service to our customers in Germany, Austria, and Switzerland, as well as neighboring countries such as Belgium. We are also happy to include validation (IQOQ) if desired.
Furthermore, membraPure supports users worldwide with personalized service, customized training, and comprehensive resources, all provided by qualified distribution partners.
Generally, there are standards according to ASTM (American Society of Testing Materials), ISO 3696, and CLSI (Clinical Laboratory Reagent Water). At membraPure, we based the design of our systems on ASTM D1193 because this standard includes the classification with the most parameters.
Pure and ultrapure water systems, which begin with purification from drinking water, always have reverse osmosis (RO) upstream. This is followed by technologies such as mixed-bed ion exchangers, electro-deionization (EDI) cells, UV disinfection, and ultrafiltration (UF). Pure water systems with dispensers have a final filter at the outlet that removes any particles from the water.
Depending on the model and configuration, < 10 ppb (Reagent), < 5 ppb (Life Science), or < 3 ppb (Analytical). The TOC monitoring option can be integrated upon customer request. This enables the system to determine the TOC value and display it to the user on the screen.
The choice depends on the required water quality (ASTM Type I, II, or III) and the quality of the source water (drinking water, pretreated water). Daily consumption and the quality of the source water are also crucial for selecting the appropriate ultrapure water system. We always like to use the FACT formula here:
Feedwater: What is the quality of your source water?
Application: What is the application for which the water is used?
Consumption: What is your daily demand? Do peak loads need to be covered?
TOC: Is organic carbon monitoring necessary?
Our ultrapure water systems are designed for installation directly at the point of use. Additionally, the systems for Type II and Type III water can be combined with an existing ring main in the building. Several systems of this type, which have already been installed, feed a centrally located tank.
Our devices are designed for quick and easy installation. This can be carried out independently by the customer or by a service technician from us or our trading partners. Larger systems with a production capacity of more than 40 L/h require professional installation.
All that's required is a water connection, a wastewater connection, and a power connection. The inlet water temperature should be in the range of 5–30 °C. Many models can be integrated directly into existing laboratory infrastructure. Configurations for under-counter, wall-mounted, or tabletop installation are available.
Yes, many models offer a direct-feed option to supply pure/ultrapure water of the appropriate water quality to HPLC, ICP-MS or clinical analyzers and even electrolyzers for hydrogen production.
Many consumables, such as cartridges and filters, can be replaced by the user themselves. Replacing the relevant components can be explained during a commissioned installation and assembly or maintenance visit. For more complex maintenance, membraPure offers and recommends appropriate support.
We recommend annual maintenance. Cartridge replacement depends on usage and water quality. The capacities of individual cartridges are available upon request, or they are stated directly in the quote. Changing the cartridge is easy and can be done in just a few minutes. The software guides the user through the process. We recommend replacing the final filter annually.
Depending on usage, approximately 12 months. The system indicates when a replacement is needed.
These are available in stock and can be shipped within 48 hours or less after receiving your order.
Yes, of course that's possible with us. The advantage of a maintenance contract is that we'll remind you in good time about your next scheduled service, and you'll have priority over customers without a contract when scheduling appointments. You'll also benefit from better pricing.
In this case, please contact our customer service by phone or email. If we are unable to assist you remotely, we will try to dispatch a service technician to your location as quickly as possible if you are located in a German-speaking country. Our local partners will be happy to assist you abroad.
