Abstract
The utility model relates to a conical air-permeable test tube, consisting of a spiral cover, an air filtering device, a sealing washer and a conical test tube, wherein an air-permeable groove and an air-permeable hole are formed in the center of the top of the spiral cover; an air filtering membrane and a membrane pressing sheet of the air filtering device are placed in the air-permeable groove; the sealing washer is placed in the spiral cover; and the spiral cover is spirally sleeved on a spiral mouth of the conical test tube. By using the sealing washer and the air filtering device, the conical air-permeable test tube effectively solves the problems that plant growth is influenced and the air-permeable pollution rate is high because of a closed process of cultivating somatic embryos to regenerate plants. The conical air-permeable test tube effectively solves the problems of waste of a culture medium and insufficient in-tube length required by root growth in the process of cultivating somatic embryos to regenerate plants, thus saving the culture medium and reducing the production cost.

Described air filter comprises air filtering film and pressuring film plate.Air filtering film diameter 15～17mm, thickness 0.11～0.13mm, aperture 0.21～0.23 μ m; Pressuring film plate diameter 15～17mm, thickness 1.2～1.4mm has equally distributed 6 scallop holes, as ventilation hole on the pressuring film plate; There are three bayonet sockets that are evenly distributed at the pressuring film plate edge, and is used with the bayonet slot of ventilating groove, blocks pressuring film plate.The air filtering film is the carbonic acid tunica fibrosa, and pressuring film plate selects for use PC as manufacturing materials.
Described seal washer internal diameter 23～25mm, external diameter 26～28mm, thickness 1.4～1.6mm; Seal washer is placed in the screw lid lid.Seal washer uses silica gel as manufacturing materials.
High 249～the 251mm of described taper test tube, diameter 29～31mm, wall thickness 0.9～1.0mm; The upper port of taper test tube is for there being externally threaded spiral mouth, and the internal thread of external screw thread and screw lid is complementary, and allows the screw lid rotation set in the spiral mouth, spiral mouth external diameter 28.3～28.5mm, internal diameter 25～27mm; The bottom of taper test tube is a conical pipe, the high 99～101mm of conical pipe.The taper test tube with PC or glass as manufacturing materials.
A kind of taper of the utility model test tube of breathing freely is used to cultivate bamboo grows somatic embryo regeneration plant, by the use of seal washer and air filter, efficiently solves airtight plant strain growth, the ventilative high problem of pollution rate of influencing of bamboo grows body embryo plant incubation.Simultaneously, the ventilative test tube of taper is guaranteeing to cultivate under the enough situations of base unit weight, prolonged the space that bamboo grows somatic embryo regeneration plant root stretches, efficiently solve the bamboo grows of test tube cultivation in the past somatic embryo regeneration plant and have the not enough problem of length in waste medium and the required pipe of bamboo grows somatic embryo regeneration plant root growth, save medium, reduce production costs.The ventilative test tube of taper also can be used for the cultivation of other plant or animal tissue or cell, has extensive use.
