The extent 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 can reduce the exploratory behavior without affecting the locomotor activity. ZH-TB-type hole-board system for behavior (head extends into the plate well), the test can be clearly assess changes in animal behavior and basic explore psychotropic drugs caused mice in the face of the new environment. By means of the plate hole miniature infrared transmitter / 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 customer applications. Vertical (horizontal) mounting structure can be easily and micromanipulator, stereotaxic instrument, such as supporting the use of biological equipment, widely used in various fields of biological experiments. KES-type syringe pump technical indicators: Maximum distance: 70mm applicable injector: 5ul-1000ul linear velocity range: 7.9 um / min-79.4mm / min adjust the resolution: 7.9 um / min Stroke Resolution: 0.165 um rated linear thrust : 20N Setting: full digital film key settings control accuracy: When ≥30% full stroke, control error ≤0.5% display: 128 × 64 graphic point of formation 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 type stereotactic syringe pump, and ZH- Lansing B type stereotaxic instrument supporting the use of experimental animals through direct injection syringes, avoid taking plastic tube system Error generated; the motor can be taken two ways of working for injection and absorption. Technical Specifications: Model can be equipped with a syringe: 1 ~ 100ul Power: 220V, 0.05A fuse: 5 * 20mm micro-stepping motor drive power the smallest step rate: 1 step (1/2 step) the maximum step rate: 400 step / second, (1/2 step) flow rate range: 0.001 ~ 200ul / min [1- 100ul syringe] Weight: 2 kg
