Automatic adjustable device for transmission of different volumes of fluid by pipet

With the dramatic growth of high technology and specialized precision of laboratory facilities, the need for special tools to help the operator to advance the goals and more precise and safer control has been predicted. The proposed device is automatic adjustable instrument for transmission of different volumes of fluid with different viscosities by pipet and had various electronic options to improve precision and higher control of the operator. The device is a combination of three common laboratory instruments including sampler, pipetboy, Dispenser. Mechanical control is done by the processor, the AMD ARM, and also the processor provides the connection between joystick controller stepper motor and gearbox. To aspirate the sample and blow-out, the cylinder and piston method and the conversion rotational motion into linear stepper motors with manifold bolts method are used. The results of the electrical and mechanical performance of the device are satisfying according to the inventions used in different parts, and also it is economical. Discussion & After several stages of the design and construction of a laboratory prototype of the device and adjusting the speed and power of the three compound devices and their shortcomings, we come to the conclusion that mono-use pipetboy devices that are on the market have a very low accuracy, and this is also true about the Sampler which has limitations in low speed and high volumes of fluid as well as dispenser devices which have a high price but low functionality and many disadvantages. However, these devices are the basic requirements of a laboratory.
