Embodiment 1

[0034] Please refer to image 3 , which is a schematic diagram of the first embodiment of the hand rest 16. It can be seen that the hand rest is a groove-shaped strip structure, including a plane 31, a first side 32 and a second side 33, and the length of the first side 32 is equal to or greater than The connection between the second side 33 , the plane 31 and the two sides is rounded and rounded. During installation, the first side 32 is inside the bracket 15 , while the second side 33 is outside the bracket 15 , and the bracket 15 is embedded in the groove of the hand rest 16 .

Embodiment 2

[0036] Please refer to Figure 4 The difference from the first embodiment is that the bottom of the first side 32 is provided with a barb 34, which makes the installation more secure.

[0037] In summary, compared with the prior art, the present invention has the following advantages and positive effects:

[0038] First of all, the invention adds a rubber hand rest, so that users can rest their hands on it when operating, and it is more comfortable than the original metal bracket when the temperature is low;

[0039] Secondly, the invention adds a rubber hand rest, which has a buffering effect. When the glass door is closed, it can make the space between the glass door and the bracket more airtight, reducing potential safety hazards;

[0040] Again, the rubber hand rest provided by the invention is very convenient to disassemble and clean.

Abstract

The invention provides a comfortable-operation biological safety cabinet which comprises a cabinet body, a bracket and a workbench, wherein the bracket of the workbench is provided with a hand support made of an elastic material; the hand support is integrally formed or spliced by a plurality of parts; the cross section of the hand support is in a groove shape; the bracket is embedded in the groove of the hand support; the hand support is enclosed into a groove by a plane, a first side edge and a second side edge; and the joints of the two side edges and the plane are arcs. The invention enables the user to operate the cabinet more comfortably at low temperature as compared with the original metal bracket; and since the rubber hand support has the cushioning effect, when the glass door is closed, the glass door and the bracket can be more closed, thereby lowering the potential safety hazard.

Description

technical field [0001] The invention relates to biological experiment equipment, in particular to a biological safety cabinet with more comfortable operation. Background technique [0002] Aerosols may be generated when liquids or semifluids are manipulated in the laboratory, such as by shaking, pouring, stirring, or dripping a liquid onto a solid surface or into another liquid. Aerosols can be generated by streaking agar plates, pipetting cell culture flasks, centrifuging infected fluids, and performing animal manipulations. For these aerosols with a diameter of less than 5 microns and tiny liquids with a diameter of 5-100 μm, which cannot be seen by the naked eye, laboratory workers are usually unaware of their existence and may inhale or cross-contaminate other materials on the work surface. [0003] Biological safety cabinets are used to protect the operator, the laboratory environment and experimental materials from exposure to the above-mentioned operations when opera...
