Problems solved by technology

[0002] During daily experiments in the biological field, beakers are often used to repeatedly clean and sterilize some experimental materials (such as seeds, leaves, etc.). Since the beaker has no isolation device, the beaker can only be held with tweezers or other tools. If the experimental skills are not skilled, it is usually easy to lose some materials and consume time and energy during this operation, resulting in waste and affecting the experimental results

Embodiment Construction

[0013] Such as figure 1 As shown, a special filter screen for beakers, the net body 1 includes a lower net circle 11 and an upper net circle 12 and will be arranged on the opposite sides of the lower net circle 11 and the upper net circle 12 for the lower net The hook column 13 fixed to the ring 11 and the upper ring 12; the lower mesh ring 11 is provided with a plurality of buckles 15 for clamping the filter screen 2; the hook column 13 is provided with at least one for The protrusion 14 overlapping the filter screen 2; the distance between the lower mesh circle 11 and the upper mesh circle 12 accounts for 1 / 3 of the height of the entire beaker.

[0014] The hook column 13 is made of flexible metal material, and the hook portion of the hook column 13 can be bent at any angle.

[0015] The diameter of the lower ring 11 is smaller than or equal to the diameter of the upper ring 12 .

[0016] The above is only a preferred embodiment of the present invention, but the scope of p...

Abstract

The invention discloses a filter screen special for a beaker. The filter screen is characterized in that: the screen body includes a lower screen ring, an upper screen ring, and hook columns disposed on opposite sides of the lower screen ring and the upper screen ring to fix the lower screen ring and the upper screen ring; the lower screen ring is provided with a plurality of buckles for buckling the filter screen; each hook column is equipped with at least one bulge for lap joint with the filter screen; and the distance between the lower screen ring and the upper screen ring accounts for 1 / 3 of the total beaker height. The filter screen special for the beaker provided by the invention has the advantages of simple structure, strong practicability, convenient use, safety and reliability, low cost and easy production, etc.

Description

technical field [0001] The invention relates to a laboratory product, in particular to a special filter screen for a beaker. Background technique [0002] During daily experiments in the biological field, beakers are often used to repeatedly clean and sterilize some experimental materials (such as seeds, leaves, etc.). Since the beaker has no isolation device, the beaker can only be held with tweezers or other tools. If the experimental skills are not skilled, it is usually easy to lose some materials and consume time and energy during this operation, resulting in waste and affecting the experimental results. Therefore, it is necessary to provide a filter screen for a beaker to solve the above problems. Contents of the invention [0003] According to the technical problem raised above, a special filter screen for beakers is provided. [0004] The technical means adopted in the present invention are as follows: [0005] A special filter screen for beakers, characterized ...
