Description

Plant tissue culture scissors

Technical Field

The utility model relates to the technical field of biological experiments, in particular to a pair of scissors for plant tissue culture.

Background

At present, plant tissue culture is also called in vitro culture, and refers to a technology of separating tissues, organs or cells, protoplasts and the like which meet the requirements from plant bodies, and culturing under an artificial control condition through aseptic operation to obtain regenerated complete plants or produce other products with economic value. The plant tissue culture is carried out in a culture bottle, when a relatively thick and hard explant needs to be cut and aseptic seedlings cultured in the bottle need to be cut, the cutting operation needs to be carried out by using scissors, and the cut explant needs to be corrected after being taken out, so that a plant stem section with two smooth end faces for experiments is obtained.

Because the knife face of the traditional scissors is smooth and flat, when plant tissues are trimmed, the stress is uneven, the plant stem section is easy to slip and difficult to cut when the plant tissue is sheared, and the incision face is uneven and the plant materials are wasted. Simultaneously because the household utensils oral area of cultivateing the plant is less, takes out in traditional scissors can only slope entering bottle, and then can lead to the plant incision uneven, current scissors is when using simultaneously, for avoiding the plant to fall into the bottle, need hold the plant with one hand, then cut with the scissors, can't carry out one-hand operation, based on above-mentioned problem, we provide a plant tissue culture scissors.
