Introduction
ME-200 Microelectrode Amplifier,is an instrument that matches Data Acquisition & Analysis system. It’s used to guide the discharge in and out of cells, exchange impedance and amplify signal in the purpose of completing the research work of cell-level biologic electric signal activity.
Characteristic
1. High Input Impedance.
2. Self LCD (liquid crystal display) monitor can display different information combination with flexible method.
3. Using fifth power of Bezier Low-pass Filter with ten gears chosen
4. Self-electric Stimulation Device could send electric stimulation to cells directly through the microelectrode. The stimulation electric current is 1nA～999nA.
5. Be able to complete the 0～30pF Negative Capacitance Compensation.
6. Stimulation signals can be cancelled by customs’ needs through Bridge Balance and Transient State Regulation.

HONGKONG LIHUA ELECTRONIC TECHNOLOGY DEVELOPMENT CO., LIMITED is specialized in the production and sales of research experiments microcirculation， using SDF technology (sidestream darkfield imaging (SDF), sidestream dark field (SDF) imaging ), the observed changes in special parts of the animal and human blood. observe the special parts of the animal or human blood flow changes.
The condition of the blood vessels and blood of experimental animals can provide for the animal experiments, in order to cardiovascular disease in experimental animals blood poisoning、sepsis and failure early noninvasive monitoring and scientific data, and provide scientific data for the human disease.
Product: sublingual microcirculation (lingua microcirculation,tongue microcirculation, cerebral microcirculation, renal microcirculation ,visualize the microcirculation at the bedside and sidestream dark field (SDF) handheld imaging device (Microvascular (blood) image observation instrument) etc.
Its technical characteristics are as follows:
(1) Use SDF technology, can observe animal or person special parts such as the tongue, kidney and other parts of the blood flow changes.
(2)can provide the number of capillaries, vascular caliber and velocity, TVD / PVD, PPV, / MFI of experimental animals of data , and so on .
(3) equipment with convenience, can be carried out directly noninvasive observed in the laboratory experiments bedside characteristics, operation is simple.
