Applications

They are very small, they are very flat, made of plastic. And they offer defined premium quality for countless applications - from the deep sea to space: our micro-pumps.

Life Science

Diagnostics

In medical diagnostics, the transport of liquid substances such as blood, urine, saliva – plus the reagents required for the test – is important for carrying out initial rapid tests or already in-depth examinations in hospitals and laboratories.

Thanks to their small size, our micropumps also show their advantages here and sometimes speed up analyses extremely, while at the same time delivering reliable results and convincingly short throughput times.

These can be life-sustaining aspects when it is necessary to assess the condition of a patient as quickly as possible in order to be able to make diagnostic decisions.

Lab-on-a-Chip

Lab-on-a-Chip refers to a system that compresses the functionality of a macroscopic laboratory onto a plastic substrate the size of a credit card.

With the help of microfluidic functional elements, the smallest samples are conveyed, mixed, filtered, separated, incubated and analysed. In this way, several indicators can be checked simultaneously and directly optically evaluated.

Together with partners, we have realised a mobile analysis unit for body fluids in the Physiocheck project, in which the micropumps are also used. And all this in the size of a microscope slide

Sensor Feeding

It is not only the small dimensions which make it possible to operate our micro-pumps as a unit with the sensor as integrated assemblies. Our pumps also consume very little power, enabling a trouble-free battery operation in order to operate small, mobile devices.

Depending on customer requirements, we can either integrate the electronics into the system electronics or install them in an enlarged pump housing.

Therefore, the areas of application of this “Supply” of the sensor ranges from the Blood glucose measurement via the blood pressure measurement, the blood oxygen saturation to the monitoring and control of anaesthetic gases.

Tissue Engineering

The Tissue Engineering concerns the artificial production of biological tissues through the targeted cultivation of cells.
A fascinating topic in medical technology.
Cartilage or other damaged structures can already be cultivated.

Researchers assumes that in the future entire organs could be grown in this way.
Our micro-pump is used, for example, in bioreactors during the growth of the cells in order to supply the growing tissue parts with nutrient fluids.

Cell Culture

In biotechnology, the growing of cell cultures is an important element. This applies to bioreactors which produce biological substances via cells and also to cell systems which are used, for example, as test systems for the effect of pharmaceuticals.

„Organ on Chip” can be mentioned as an example: The cultivation of entire cell lines is intended to make comparable cell material available for investigations. In order for the cells to fulfil their tasks, they have to be supplied with the appropriate material in the bioreactors. This includes the appropriate temperature and light conditions as well as the supply of nutrients (e.g. glucose) or the addition of growth promoters or inhibitors.
Many tasks can be performed by automatic pump systems, which are superior to purely manual dosing in quality and convenience. Our micropumps can be placed very close to the reactors due to their small design, low energy requirements and long lifetime. The placement in the incubator is therefore also easy to set up.

Identification of MRSA and COVID-19 Germs

In medical diagnostics, the transport of fluid substances such as blood, urine, saliva – plus the reagents necessary for the test – is important in order to carry out initial rapid tests or more in-depth examinations in hospitals and laboratories.

Here, too, our micro-pumps display their advantages thanks to their small size and sometimes significantly accelerate the analysis, while at the same time delivering reliable results and impress with short lead times.

These can be life-sustaining aspects when it comes to assessing a patient’s condition as quickly as possible in order to be able to make diagnostic decisions.

Spray Generation

Thanks to the combination of our pumps with different spray technologies, we can atomise numerous fluids – down to almost molecular size.

Originally, we used the necessary micro-pump to atomise active ingredients and fragrances.
Of course, the working principle also works in countless other areas. You can also atomise drugs in this way.

The variety of applications is literally limitless.

Drug Dosage

Dosing fluid drugs in a defined time and amount can be done either as stationary or with the help of transportable solutions.

In combination with a sensor even in mobile infusion our micro-pumps ensure a precise dosing that is absolutely reliable over a long period of time.

For this we test every single pump in the entire production process and can thus guarantee the quality level of our products at the highest level.

Negative Wound Pressure Therapy

The micropump creates a controlled, localized negative pressure in a wound, thereby accelerating the healing process in wounds. By using micropumps, this procedure can now also be used in a mobile way and not just as before mainly in stationary applications.

Fragrance Dispensing

Lifestyle is not a trend, but an all-encompassing attitude to life. We have only limited influence on whether world around us smells good, but we can influence the olfactory atmosphere in our own homes, in the car, at work, etc. But even in public buildings and rooms, odours can be adjusted between neutralisation and refreshment.

Modern room scenting systems can use micro-pumps to disperse a defined fragrance over a long period of time without using individual fragrances more quickly than others, because the precise liquid transports guarantee the correct mixing ratios of the fragrance at any given moment. That is why, moreover, that the fragrance remains unchanged during operation.

In all cases, our micro-pumps, equipped with a sensor, can precisely dose the liquids to be atomised in order to pamper the environment with a very personal scent.

Robotic

Robotics is one of the fastest-growing fields of technology. Areas such as engine technology, hydraulics and pneumatics, improved image processing and also artificial intelligence (AI) have contributed to this growth. In recent years, robotic systems have become increasingly powerful and smaller.

Our micro-pump enables – by pumping gases or liquids – significant pressures to be built up. This makes it an important component of this development. Especially in the field of soft robotics (i.e. the use of flexible materials which can change their shape by pressure from inside) is extremely exciting. Here, the flat design and the compact control of our pump opens up the possibility to realise actuator functions in small to very small dimensions.

Sensors

Industrial processes must become increasingly safe and efficient. Sensors play an important role here. In order to obtain stable and clear measured values, the sensor must be reliably supplied with the analysis fluid. A technical challenge which our micropump can easily meet.

The system can react more quickly to fluctuations in measured values and/or compensate for changing concentrations, as can occur with catalytic gas sensors, for example.

As many sensors, on the other hand, do not function properly with a passive flow, our micropumps can open up new areas of application and not only save lives in detection. One example would be water sampling. The water quality should be checked for legionella, lead, heavy metals, pharmaceuticals or pesticides. If certain substances are added to the water, this can be done with a second pump.

Microdosing

In ever smaller automatic coffee machines the micro-dosage of complementary flavours with the help of our micro-pumps can create first-class coffee specialities.

Vanilla, Caramel, Amarena … as always:

The dose determines the quality.

So the flavour additives must be put in a nutshell so that a first-class coffee becomes an outstanding speciality.

Aerospace​

Space missions are extremely expensive high-tech projects where the technology has to ensure maximum reliability. If a component fails in space, tens of millions are lost, sometimes this is in the billions.

Also for this reason, the student small satellite group of the University of Stuttgart e.V. (KSat) has worked on a practice project with a maintenance-friendly Bartel pump, which operates without mechanical parts: the mp6.

This micro-pump will now make its way to the ISS where it will pump a ferrofluidic fluid to test a NASA experiment for an alternative rocket propulsion in weightlessness.

Bartels goes Orbit.

Nebulisation

The generation of a spray plays a major role in many applications. This can be the inhalation of medication, spraying disinfectant solution or applying perfume to the skin.

We have experience of how such a spray can be created – collision of liquid jets, vibrating piezos, or electro-fogging. We also have experience in using our micropump components and processes to deliver the necessary liquids to the spray systems in a controlled manner.

Compared to many conventional methods of liquid supply, this has the advantage of quantity control and geometric flexibility.
