The degree of spontaneous activity ZH-TB type hole plate system detects mouse can be used for drugs, general pharmacology, research and central nervous system excitability, inhibition studies, central stimulant drugs can significantly increase voluntary activity reduced exploratory behavior, certain doses of antipsychotic drugs may reduce exploratory behavior without affecting the locomotor activity. ZH-TB-type hole plate system for behavior (head stretching plate hole), the test can be clearly assess changes in animal behavior and basic exploration caused by psychotropic drugs in mice in the face of the new environment. By means of the micro-plate well infrared emitter / receiver automatically recorded. KES-type syringe pump syringe pump is mainly used for small-time quantitative measurement of injection drug equipment. Precision, small, compact, easy to install, easy to operate. Standard specifications can be installed ul injector, precise stroke control and wide range of line speeds to meet different user applications. Vertical (horizontal) structure can be easily installed and micromanipulator, stereotaxic instrument, such as supporting the use of bio-instruments, widely used in various fields of biological experiments. KES-type syringe pump Specifications: Maximum stroke: 70mm applicable injector: 5ul-1000ul line speed range: 7.9 um / min-79.4mm / min to adjust the resolution: 7.9 um / min Stroke Resolution: 0.165 um rated linear thrust : 20N settings: full digital film key settings control accuracy: when ≥30% full stroke, control error ≤0.5% Display: 128 × 64 graphic dot matrix LCD external control interface: start-stop control, fast forward control, fast back control communication interface: RS485 Power supply: AC220V ± 10%, 50HZ / 60HZ Power consumption: <10W Working environment: temperature 0-40 ℃, relative humidity <80% Dimensions (L × W × H): 180 × 46 × 78 (mm) Weight: 0.6KG Protection grade: 1P21 KDS310 stereotaxic microinjection pump type, and type B ZH- Lansing stereotaxic instrument supporting the use of experimental animals had direct injection syringes, plastic tubing way to avoid taking error produced; motors can take the injection and absorption work in two ways. Technical Specifications: Model can be equipped with a syringe: 1 ~ 100ul Power: 220V, 0.05A fuse: 5 * 20mm micro-stepping motor drive power minimum step rate: 1 step (1/2 step) the maximum step rate: 400 steps / second, (1/2 step) flow rate range: 0.001 ~ 200ul / min [1- 100ul syringe] Weight: 2 kg
