Get an efficient, repeatable, and temperature-independent process
Use our all-in-one setup for different samples and various containers
Many configurations available to fit your system’s requirements
Dispensing an accurate volume of liquid is a common requirement to many different industries where specific liquids need to be precisely added into vials, tubes or microplates in an automated manner.
Whether it is for reagent preparation, manufacturing, or dosing applications, the same advantages are found:
Nevertheless, existing solutions often lack in versatility and sometimes cannot cover the overall requirements of the application.
We offer a tailored solution with high versatility, which enables fast and precise volume dispensing with a high degree of control over the actual results, and an automatic correction of any drift that could happen over time (change of temperature, change of viscosity, variations due to the system).
To do this, we offer you a setup in which the injected volume is controlled by the opening time of a fast-switching valve, downstream of a liquid under constant pressure. When the valve is open, the liquid flows at a rate that is measured by a high-accuracy flow sensor. In the event of a drift, the total volume of liquid injected over one cycle can be corrected by applying a larger or smaller pressure over the liquid, thanks to our high-accuracy high-response time pressure controller (see figure below).
There are numerous industrial uses for automated sample dispensing, including:
Overall, automated sample dispensing systems make the process faster, more efficient, repeatable, and temperature-independent, leading to increased productivity and reduced costs in various industries.
With our all-in-one setup, you can get all of this for your industrial process starting from 5K Euros!
For sample dispensing, you can either use MFS flow sensor (Elveflow) based on thermal conductivity technology, or Bronkhorst flow sensor (Elveflow) based on Coriolis principles, that is temperature independent. Both sensors have pros and cons. We provide some features of these two sensors to help you choose the one that is convenient for your application and budget.
Elveflow offers different Premium Coriolis flow rate sensors, which vary by their operating flow rate range. The following table sums up the main features of the different sensors:
(1) Guaranteed at constant temperature and for unchanging process and environment conditions.
(2) Depends on flow rate, heat capacity fluid, T amb., T fluid and cooling capacity.
(3) To be rigidly bolted to a stiff and heavy mass or construction for guaranteed stability. External shocks or vibrations should be avoided.
