FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring
Read moreThe flow cell with integrated stirring and reduced hydrodynamic noise is designed for the determination of single analyte using one miniature ion-selective electrode (ISE) and one miniature reference electrode with a diameter of 6 mm and length of 60 mm.
Rotation speed of integrated stirrer: 10-4000 rmp.
Miniature ion-selective electrodes and reference electrode were designed for integration into the flow cell for determination of Cl-, K+, Ca2+ and Na+ ions.
In flow mode, the system can operate automatically. The speed of the integrated stirrer can also be controlled by applying the corresponding voltage to the motor, connected to a stabilized source.
The flow cell with one selected ISE can be used for:
- Automatic or semi-automatic measurement of concentration of Cl-, K+, Ca2+ and Na+ ions in various solutions (following prior calibration)
- For continuous measurement of changes in concentration of Cl-, K+, Ca2+ and Na+ ions.
* For this product, we recommend our customers use the Training Service from BVT.

FC2.TL.* PMMA Flow Cell
Read moreThe flow cell enables the use of Screen printed sensors in a flow through arrangement.
The flow cell is suitable for sensors of type AC1, AC2, CC1, CC2 and CC3.
The Screen printed sensor is inserted into the slit of cell and tightened by closing of the door. The cell ensures the wall-jet flow around the working electrode and it is optimised so that no air bubbles cumulate in the cell. The cell contains also the contact and output cable.
With the sensors enclosed in a flow cell, it is possible to measure semi-automatically or automatically using a pump or liquid switch for sample supply. Under such conditions, maximum measurement reproducibility is ensured.

MDC1 Microdialysis Catheter for “in vitro” Measurement
Read moreThe microflow cell FC2 (BVT Technologies, a.s.) connected with microdialysis catheter PME011 (Probe Scientific, Ltd., UK) enables continuous monitoring of low-molecular substances in circulating blood without withdrawing blood from the tested body. (The device is not approved for human use as a whole; the microdialysis catheter has the approval for medical use).
SPE electrochemical sensors and biosensors can be enclosed in the FC2 cell – e.g. the AC1.GOD sensor for measuring glucose. The advantage of this system is the defined and sterile conditions under which the sample is fed through the microdialysis catheter to the working electrode of the SPE sensor.
The device can be also used for measurement in fermentation reactors, in subcutaneous tissues or in special scientific apparatuses. The main advantage of this catheter is in a special membrane which produces a “plasma-like” or “prefiltered sample” sample without the need for blood centrifugation or deproteinization.
MDC1 makes online monitoring of different blood parameters (biochemical compounds actual concentration or kinetics of enzymatic reactions) possible. The device is also convenient for pharmacological studies. The device can be used only for non human applications.

SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)
Read moreThe SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.
The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H2O2 which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.* For this product, we recommend our customers use the Training Service from BVT.
