A device that comes naturally in the scientific, medical laboratories and research, the scientific precision pump. This simple but extremely useful machine does the work of what may be manual activities, and this is often neglected until it breaks. Pumps laboratory scientific instruments of today have not changed much in many years because they work well in the configuration are currently conceived.
The main types of pumps, peristaltic pumps used today scientificPumps. This design has been instrumental in the development of the dialysis machine, which can be used when a patient has kidney to filter impurities and waste from the blood to fail. The pump was such that, when pumping blood through the machine, the blood would not have damaged the pumps are under development. The peristaltic pump is so because the action can be used on the tube, called to bring the liquid.
Peristalsis is the action of squeezing a tube in the linear sequence, in a moving fluidMoving forward. The round design of the pump hose is simple: The rolls are placed in a spinning wheel and the rollers rest on top of the tube containing the liquid. As the wheel turns, it pushes the tube in a fluid and consistent, the strength of the liquid along the tube without damage.
This design is made of scientific precision pumps. The motor, pump system is connected to the phase-out or pushed to react in small steps. This can give youexact amount of liquid instruments that are the testing procedures. As the motor phases in a clockwise direction, press the peristaltic rollers, the exact amount of liquid in the calibration of acting as an automatic system for the management of doses pipette reagents or samples.
Other scientific controlled piston pump. Many medical analysis devices use this type of pump for irrigation, the sensor's mixing of reagents and also the mixing of sample and diluent. Many of thesePiston pumps are used for scientific purposes, the supply of purified water. It can be calibrated and adjusted for temperature variations and uses the type of liquid.
There are air pumps that use air pressure to move a diaphragm in a pumping motion. The liquid moves must be moved across the membrane, and when the air pressure on the opposite side, the decline of diaphragm pumps the fluid through the valve, arranged to maintain a constant flow of liquid. This type ofThe scientific pumps can be calibrated to give a certain rate of flow or even used to increase the fluid pressure within the pipe system tools'.
Some scientific pumping is done by gravity and precision control valve. The reagent is installed above the work area, as required and reagent systems, precision valves are electronically controlled to deliver precise amount of reagent during execution tools.
A more scientific method is done by the pump impeller. This isuseful when mixing the purified water or other reagents prior to testing. The impeller can be electronically controlled to run at precision speeds or times, and are excellent for mixing.
It is plainly seen that the scientific pumps listed are needed and taken for granted. As they work hard in the background, we will only notice them when they stop working properly.
