Floating sample sterilizing device

Abstract

The invention discloses a floating sample sterilizing device. The floating sample sterilizing device comprises a tissue culture vessel, a vessel cap, a connecting pipe, a fixing pipe, a baffle, a clamping block and an elastic steel wire, wherein the vessel cap is in threaded connection to an opening of the tissue culture vessel; the upper end of the connecting pipe is fixedly connected with the vessel cap; a plurality of clamping groove holes are formed in the connecting pipe in the length direction; the upper end of the fixing pipe is inserted into the connecting pipe; a porous channel is formed in the fixing pipe in radial direction; a plurality of through holes are formed in the baffle; the lower end of the fixing pipe is fixedly connected with the baffle; the clamping block is arrangedin the porous channel in a sliding manner; the diameter of the clamping groove hole is not smaller than that of the porous channel; and one end of the elastic steel wire is inserted into the clampingblock, and the other end of the elastic steel wire is propped against the inner wall of the fixing pipe. According to the floating sample sterilizing device disclosed by the invention, the height ofthe baffle is adjusted in a manner of changing the position of the clamping groove hole of the clamping block, so that nymphaea tetragona leaves are still soaked below the liquid surface of a sterilesolution, waste of a sterilizing agent is reduced, and environmental pollution is reduced; and a detachable connection manner is adopted, so that cleaning and storing are convenient.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a sterilizing device for floating samples. Background technique [0002] Nymphaeaceae (Nymphaeaceae) NymphaeaLinn. plants are perennial herbaceous plants, because of their high ornamental, edible and medicinal value, they can be widely used in garden landscape, medicine, food and daily chemical industry and other fields. With the opening and circulation of the international flower market, new species and varieties of tropical water lilies have been continuously introduced into China in recent years, such as Hainan, Fujian, Guangzhou, Suzhou, Hangzhou, Qingdao and other provinces and cities have successively carried out the breeding and scale of fine varieties of tropical water lilies. The industrialization of water lilies shows a trend of expansion and development. [0003] In the field cultivation of water lilies, ramets or sowing propagation methods are usually us...
