ZH-PL type critters running wheel system running wheel system is flexible and suitable for small animal research facilities, is rhythm, food, medicine or pharmacy animal studies circadian cycle valuable instrument. Compared with the treadmill, swimming pool training equipment, running round the system in small animal behavior research exercise physiology, pharmacology, neurophysiology, etc. There are more prominent advantages, has been recognized by experts and scholars, is the preferred laboratory exercise training equipment. Among them, the self-running wheel (Passive Running Wheel) is a spontaneous movement by the animals themselves to promote running wheel rotation. In this configuration, the information long-term animal cage activities, such as running wheel rotation direction, the number of revolutions, the cumulative total travel, etc., can use the magnetic switch and smart meter length recording, magnetic switches can also be obtained and data acquisition systems. Independent ran round the system works with the product type Independent wheel system is run by the animal's own campaign to drive the wheel operation unit, which consists of self-running wheel apparatus, data logging recorders and statistical analysis software consists of three parts. Independent wheel running rodent autonomous movement means, which consists of the wheel assembly, the cage body, and the rotation direction speed sensor. Cage is divided into: Cage base facilities inside the cage and removable tray to collect waste. Easy to clean the entire cage body. Running wheel system is a modular combination of design, may constitute a running wheel, drag the running wheel or wireless data transmission confined ran round three. In addition, running wheel removed, you can easily build a standard cages. Rats or mice can be used to run different size wheels. Available running wheel geometry as follows: Hold the mouse wheel diameter (mm) running wheel width (mm) spoke Diameter (mm) spokes-center spacing (mm) mice 118/240/250 40/80 Ф4 / Ф2 9/6 Rat 280/340/350 90/95 Ф5 / Ф2 15 / 10.8 standard rat running wheel dimensions as: L × H × W = 520mm × 395mm × 360 running wheel products are divided into the following two types: A, independent ran round the cage body, running the length of the wheel and smart meter components. B, independent wheel system run independently run small animals up to by a number of independent wheel system running wheel and data collection, the three most computers and software, the system may consist of (optional) 2-16 independent running wheel. Standard configuration consists of eight running wheel components. Second, the running wheel structure features 1. laboratory animals run round is made of high quality material transparent bulletproof glass, stainless steel production, to facilitate direct observation of the animals active. 2. The running wheel spacious enough for large size independent rotation rat animal experiments. 3. equipped with drinking cups and food baskets, external cleaning feces, urine tray, removable transparent cage body surrounded by bullet-proof glass protection, the state does not interfere with animal life is particularly convenient when the animal is placed, remove and clean, remove sewage matter , and also to prevent the escape of animals out. 4. Running wheel rotation run smoothly without noise and durable. 5. sensor with anti-pollution, anti-electromagnetic interference, and can be placed in long-term animal feeding in the work environment. Third, the technical characteristics of the system running wheel 1. critters running wheel speed sensor has a direction, to facilitate monitoring of the movement parameters; function is stable, reproducible, and can carry out long-term animal movement effective quantitative measurements. 2. Adjust the exercise load flexibility, little animals stimulation and interference. 3. Small animal movement parameter display digital data transmission standardization. The modular design, the use of functional diversification, operating digitized.
