Advantage:
1. The large screen LCD screen displays 8-speed settings and battery information
2. Touch the governor button to easily adjust the speed of the suction and split skimming
3. The speed of suction and separation controlled by the fingertip ensures the accuracy of pipetting
4. The range is 0.1 to 100 ml. Easy control with one hand
5. The lightweight, wireless, and ergonomic design makes the pipetting operation simple and efficient
6. Through the circuit feedback automatically adjust the speed of suction and separation of replaceable lithium battery for a long time, with no memory effect.
7. Warning function when the power is insufficient
8. High-power motor can quickly fill with 100ml of liquid
Dalong pipette (pipette gun)
1. Use suitable suction tips: To ensure better accuracy and accuracy, the pipette volume is recommended within 35% to 100% of the suction tip range.
2. Installation of suction head: for most brands of pipettes, especially multi-channel pipettes, it is not easy to install a suction head: in order to pursue good sealing, need to transfer the handle inserted into the suction head, left and right rotation or front and back shake force tight. Some people will use the pipette to repeatedly hit the suction head to tighten, but this operation will lead to the deformation of the suction head and affect the accuracy, serious damage to the pipette, so such an operation should be avoided. RAININ (Ruining) multi-channel pipette has no O ring, and with the suction head with the front stop point, it can reach the ideal seal, which is really good news for multi-channel pipette users.
3. The immersion angle and depth of the suction head: the dip angle is controlled within 20 degrees and kept vertical; the immersion depth of the suction head is recommended as follows:
Pitter specifications The suction head is immersed in the depth
2µL and 10 µL 1 mm
20µL and 100 µL 2-3 mm
200µl and 1000 µL 3-6 mm
5000 µL和10 mL 6-10 mm
For normal-temperature samples, the suction head helps to improve the accuracy; but for high-temperature or low-temperature samples, the operation accuracy, please pay special attention.
4. Pump speed: Pipetting operation shall maintain smooth keep smooth and appropriate suction speed; too fast suction speed easily causes samples to enter the handle thimble handle, causing damage to the piston and sealing ring seal ring and cross-contamination of the sample.
