Abstract

The embodiment of the invention discloses a precision finely adjustable liquid transfer device, which comprises a liquid suction rod 20, a handle 13 serving as a shell, a fine adjustment rotary quantifying rod 1, an inner cavity 23 and a piston rod 17 in the inner cavity 23, and is characterized by also comprising a fixed display scale mirror 2 arranged on the handle 13 serving as a shell, wherein a sliding fine scale block 6 is arranged at a position, which is opposite to the position of the fixed display scale mirror, in the inner cavity 23; and the sliding fine scale block 6 move synchronously together with the fine adjustment rotary quantifying rod 1 and the piston rod 17. The precision finely adjustable liquid transfer device provided by the embodiment has high liquid transfer measurement precision and can eliminate accumulated error. Meanwhile, the structure of the liquid transfer device is simple, and the cost is relatively low.

Description

technical field [0001] The invention relates to the field of precision measuring instruments, in particular to a precise fine-tuning pipette. Background technique [0002] Pipettes are commonly used instruments in clinical diagnostic laboratories, biotechnology laboratories, pharmaceutical and chemical laboratories, environmental laboratories, and food laboratories, especially micropipettes, which play an important role in fine experiments. Micropipettes are divided into two types: quantitative and adjustable. There are many types of fine-tunable pipettes available, including volume changes from 0.1 μl to 5ml, which meet routine needs. However, its pipetting measurement accuracy is not high, and the pipetting measurement error is relatively large due to the accumulated error of long-term use. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a precise fine-tunable pipette with a simple structure...
