To choose a reliable, cheap pump, you must start from the following aspects: The choice of pump manufacturers in the purchase of pump, it is best to advise the pump; If the lack of people, may wish to ask a pump Old users, especially those with similar or similar conditions of their own use. First of all, to recognize the pump manufacturer, it is recommended to give priority to buy water-filled submersible pump. To see the grades and product certification, must not buy "three no" products. At the same time, should be based on local power supply situation to decide with single-phase pump or three-phase pump. Determine the pump parameters Select submersible pump focus is to determine the pump head and flow and other parameters, the user needs the best lift and pump nameplate on the head close. General deviation of not more than 20% can be more energy-efficient work. If you choose the pump head is too small, low-lift pump for high-lift work, that is, "small horse drawn cart", even if pumping water, water will be small; pump head is too high, high lift pump for low lift Work, that is, "big horse car", there will be running flow is too large, the motor overload, if the long run, the motor temperature, the winding insulation will gradually aging, or even burn the motor. Pump flow selection, water and water to the amount of water and the local economic conditions to adapt to specific problems to be treated specifically. Check the quality of the pump Submersible pump motor water filled, oil-filled and shielded structure, a water-filled applications the most widely used. The pump before use, you must unscrew the two water holes bolt, a water injection (no sand), the other to discharge air, water and other static after waiting for about 15 minutes, and so the motor cavity air after all the discharge and then add water , Until after filling the water and then tighten the two water bolts. The motor is sealed. Motor water, the winding work in the water, the motor insulation can be measured, measured insulation resistance must be megger, can not use a multimeter. Multimeter range is limited, the insulation resistance between the winding and the ground test is not clear. Insulation qualified, the pump test run test. Wherever possible, after filling the motor with water, tighten the water injection bolt, the pump can be energized in the pool test run, but can not operate for a long time, no conditions can be idle down the well, but the time shall not exceed 2 to 3 seconds .

What Are PCR Plates?
Researchers often use PCR plates in high-throughput screening thermocycler applications due to their compatibility with most thermal cyclers. The uniform and thin walls enable a precise thermal transfer. The wells are often raised slightly to accommodate sealing mat, film, and foil. They are also autoclavable.
