Water bath shaker with adjustable oscillation stroke

Abstract

The invention discloses a water bath shaker with an adjustable oscillation stroke, and the water bath shaker comprises a controller, a motor, a casing, a bed body, an upper cover, an optical shaft, aheating device, a water tank, a stroke adjusting device and a connecting member. The upper cover is connected to the casing by a hinge; the optical shaft is fixed in the casing; the two sides of the bed body are slidably connected to the optical shaft by a pulley; the bed body has a spring clip; the water tank, the motor and the controller are mounted inside the casing; the heating device is installed at the bottom of the water tank; the stroke adjusting device is connected to the motor; one end of the connecting member is connected to the stroke adjusting device, and the other end of the connecting member is connected to the bed body. Through the stroke adjusting device, the oscillation stroke of the bed can be adjusted, according to experimental requirements, an appropriate vibration amplitude can be selected to prevent water from being splashed into a sample due to excessive vibration amplitudes to affect experimental results, and the accuracy of experimental results can be ensured.

Description

technical field [0001] The invention relates to the field of laboratory supplies, in particular to a water-bath shaker with adjustable oscillation stroke. Background technique [0002] The water bath shaker is a biochemical instrument combined with a temperature-controllable constant temperature water bath and an oscillator. It is mainly used for biological, biochemical, cell Vibration culture of various liquid and solid-liquid mixtures such as bacteria and strains. A stainless steel tubular heater is placed horizontally in the water bath shaker, and a perforated bed is placed inside the water tank, which can be adapted to vessels of different specifications. Although the vibration frequency of the current water-bath shaker is adjustable, there are problems of fixed vibration amplitude and single oscillation stroke. It is impossible to select the appropriate vibration amplitude according to the requirements of the experiment, resulting in waste of energy, and the vibration ...

AI Technical Summary

Problems solved by technology

Although the vibration frequency of the current water-bath shaker is adjustable, there are problems of fixed vibration amplitude and single oscillation stroke. It is impossible to select the appropriate vibration amplitude according to the requirements of the experiment, resulting in waste of energy, and the vibration amplitude is too large. It is easy to cause water splashing into the sample, seriously affecting the experimental results
