Introduction to Prande pipette instructions
How should the Prande pipette be used? This is some of the problems that some newcomers often encounter. In order to make everyone better use the Prande pipette, the Shanghai Bayu technicians have specially compiled the use details of the Prande pipette, hoping to help everyone.
1 . Use a suitable Prande pipette tip
To ensure better accuracy and accuracy, it is recommended that the amount of pipetting be within the range of 35 % - 100 % of the tip .
2 . Installation of Prande pipette tips
For most brands of pipettes, especially multi-channel pipettes, it is not easy to install the tip: in order to achieve a good seal, you need to insert the pipette handle into the tip, turn it left and right or shake it back and forth. . Some people will use the pipette to repeatedly hit the tip to tighten, but this operation will cause the tip to deform and affect the accuracy, and serious will damage the pipette, so this operation should be avoided. The multi-channel pipette of BRAND ( Prande , Germany ) does not have an O -ring. With the tip of the front stop, the ideal seal can be achieved with a gentle press. It is the gospel of multi-channel pipette users. .
3 . Prande pipette tip immersion angle and depth
The tip immersion angle is controlled within 20 degrees of inclination and is kept vertical; the tip immersion depth is recommended as follows:
Pipette specifications Tip immersion depth
2 μ L and 10 μ L 1 mm
20 μ L and 100 μ L 2-3 mm
200 μ L and 1000 μ L 3-6 mm
5000 μ L and 10 mL 6-10 mm
For normal temperature samples, the rinsing of the tips helps to improve accuracy; however, for high temperature or low temperature samples, the rinsing of the tips reduces the accuracy of the operation, so please pay special attention.
4 . Prande pipette aspiration rate
Pipetting should maintain a smooth, suitable rate of pipetting; too fast aspiration rate can easily cause the sample to enter the sleeve, causing damage to the piston and seal and cross-contamination of the sample.
Precautions for using Prande pipettes:
1. Maintain the correct posture when pipetting; do not hold the pipette at all times, use a pipette with a finger hook to help relieve hand fatigue; if possible, change hands frequently.
2. Regularly check the sealing condition of the pipette. If the seal is aged or leaks, the seal should be replaced in time.
3. Correct the pipette 1-2 times a year ( depending on the frequency of use ) .
4 , most pipettes, before use and after a period of use, the piston should be coated with a layer of lubricating oil to maintain the seal; and for the BRAND ( Germany Prande ) conventional range of pipettes, not coated Lubricating oils also have the ideal seal.
