The Advantages and Detail Improvement of Digital Pipette

The pipette is an indispensable experimental instrument in biological research, and its accessory pipette tips are also used in large quantities. The pipette tips on the market are basically made of polypropylene plastics, and this material is colorless transparent plastic with high chemical inertness and a wide temperature range. However, although most of them are called polypropylene, the quality will be very different: high-quality pipettes are generally made of natural polypropylene, while low-cost pipette tips are likely to use recycled polypropylene plastics which uses polypropylene as the main ingredient.

Generally, the digital pipette combines the features of easy control, light, and handiness of the manual operation pipette with the accuracy and efficiency of the electronic pipette. To be specific, the mechanized operation can not only reduce the effect of hand during operating the manual operation pipette but also can lower the risk of damage which is caused by repeated pipetting.

In order to implement easy pipetting in daily operations in the laboratory, most of the digital pipettes are designed with one button solution to the basic pipetting functions, including going forward, back up, distribution, and dilution. Moreover, a number of programs can meet the requirements of most users as well as save them time.

Electronic Control Digital Pipette Epipette

Respectively, the digital pipette with normal phase technology is suggested to apply for aqueous solution, such as buffer solution, diluted acid, and dilute alkali. When referring to the digital pipette with reverse-phase technology, it is suitable for the distribution of liquid that has high viscosity or can easily generate bubbles. Also, this technology is suggested to apply the liquid with a small distribution volume.

Furthermore, with the function of continuous pipetting, the digital pipette can repeat and distribute certain selected liquid volumes, and it is especially suitable for the application of microplate.

The Detail Improvement of Pipette

Forward and Reverse Suction
The forward pipetting refers to the normal suction mode. During operation, the suction can press the button to the first gear, perform the suction task, and then release the button. When the liquid is released, press the first gear again, the pipette discharges most of the liquid, then press the second gear to drain the remaining liquid. Reverse suction means that the button is pressed directly to the second stage of the suction and then released so that more liquid will be inhaled, just press the second gear, and the liquid discharged immediately. The multi-suction liquid can compensate for the surface adsorption inside the suction head, and the reverse suction liquid is generally used in combination with the pre-wetting suction method, which is suitable for viscous liquids and volatile liquids.

Nowadays, the pipette is making excellent performances on the working efficiency and experience of human engineering in laboratory applications.

Specifically, most of the pipettes are easy to adjust their volumes and very silent during operation. At the same time, the laboratory workers can adjust the volume with a single hand. In addition, the safety of the volume lock is strengthened to avoid unexpected changes in the volume in the process of pipetting.

It is true that a small improvement in details can result in obvious effects. Currently, most of the pipettes are designed with a nonskid ring to make the users more confident when adjusting the volumes. Some of the pipettes are even equipped with anti-slip stickers to make the holding safer and more comfortable. Also, the wide button for unloading the tips on electronic control digital pipettes can provide more operation space for the users.

In general, the design of the pipettes is light and hardy. The users only need to spend little energy to complete the operation which reduces the Repetitive Strain Injury and does not influence the application effect. This means the users can confidently operate every single pipette as comfortably as possible every day in the laboratories.
