Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen blowing instrument equipment, in particular to a nitrogen blowing instrument refractor. Background Art

[0002] The laboratory uses a nitrogen blower to blow dry the 96-well plate. Nitrogen blower is often used for liquid-liquid extraction. Liquid-liquid extraction uses a large amount of organic reagents for extraction. The organic reagents will volatilize when heated by nitrogen blower. Therefore, the nitrogen blower is installed in a fume hood for use. In the fume hood, the organic reagents volatilize and the volatile gases can be removed through the fume hood to protect personnel and prevent inhalation hazards.

[0003] However, when starting nitrogen blowing, put the probe deep into the 96-well plate and turn on the nitrogen. At this time, it is necessary to observe whether the liquid level fluctuation height of the nitrogen blowing sample is appropriate. Because it has been installed, you can only manually put your head deep into the fume hood to observe. It is not suitable to observe at this time and personnel will inhale organic reagents, which will cause harm to the body.

[0004] After the nitrogen blowdown is completed, it is necessary to observe whether the liquid is completely dried. At this time, the nitrogen blowdown can only be turned off, the 96-well plate is removed, and then observation is carried out again. If it is not dried, it needs to be reinstalled and nitrogen blowdown is continued. This process is repeated until the liquid is completely dried. The observation process is complicated and wastes experimental time.

[0005] In order to solve the above problems, a nitrogen blowdown instrument refractor is proposed. Utility Model Content

[0006] In response to the above technical problems, the utility model provides a nitrogen blowing instrument refractor, which is characterized by comprising a fume hood, a nitrogen blowing instrument body, a lighting lamp, a placement plate, a slide, a support plate, a transverse groove, a guide rod, a slider, a connecting block, a turning mirror, and a refraction lens. The nitrogen blowing instrument body is arranged on the fume hood, a lighting lamp is arranged next to the nitrogen blowing instrument body, a placement plate is arranged on the fume hood, a slide is provided on the placement plate, a support plate is arranged in the slide, a transverse groove is arranged on the support plate, a guide rod is arranged in the transverse groove, a slider is arranged in the transverse groove, a connecting block is arranged on the slider, a turning mirror is arranged on the connecting block, and a refraction lens is arranged in the turning mirror;

[0007] Furthermore, the nitrogen blowing instrument body is connected to an external controller, a 96-well plate is placed on the nitrogen blowing instrument body, and there are several lighting lamps evenly distributed around the nitrogen blowing instrument body;

[0008] Furthermore, there are two placement plates, which are symmetrically arranged on both side walls of the fume hood, each placement plate has a slide groove, and two slide groove brackets are provided with support plates, the center of the support plate has a transverse groove, the center of the transverse groove has a guide rod, the slider has an opening, the slider is sleeved on the guide rod and limited by the transverse groove, and a connecting block is fixed on the slider;

[0009] Furthermore, a turning mirror is fixedly provided at the front end of the connecting block, and the turning mirror has two bends, and a refractive lens is fixed in each bend.

[0010] Beneficial effects of the utility model:

[0011] The utility model places a 96-well plate on the nitrogen blowing instrument body for nitrogen blowing, and the 96-well plate is illuminated by an illuminating lamp. When observation is needed, the supporting plate is pulled out from the placement plate along the slide groove, and the slider is moved left and right, so that the slider moves left and right in the transverse groove along the guide rod. The front-back and left-right movements make the direction-changing mirror on the connecting block move to just above the 96-well plate, and observation is performed from the upper end of the direction-changing mirror. The 96-well plate is illuminated by the illuminating lamp, and the light is transmitted to the eyes of the observer at the upper end of the direction-changing mirror through two refracting lenses to complete the observation. There is no need to put the head deep into the fume hood for observation, which reduces the harm to the body. At the same time, there is no need to turn off the nitrogen blowing, and observation can be performed, thereby improving the usability. BRIEF DESCRIPTION OF THE DRAWINGS
