MICRODIALYSIS CATHETER FOR "IN VITRO" MEASUREMENT - MDC1, new device developed in cooperation with Probe Scientific, Ltd., UK, integrates the microflow cell FC2 (BVT Technologies a.s.) interconnected with microdialysis catheter PME011 (Probe Scientific, Ltd., UK). MDC1 enables continuous monitoring of low-molecular substances in circulating blood without withdrawing blood from the testing animal. (The device is not approved for human use as a whole; the microdialysis catheter has the approval for medical use). 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 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. |
