Embodiment Construction

[0010] The sulfur hexafluoride permeation tube culture bottle of the present invention comprises a bottle body 3 and a bottle cap 2, the junction of the bottle body 3 and the bottle cap 2 is a frosted surface, the top of the bottle cap 2 is provided with an air outlet 1, and the bottle body 3 An air inlet 5 is provided at the bottom, and an air distribution plate 4 is provided above the air inlet at the lower part of the bottle body.

[0011] When in use, the bottle cap is now removed, put into the sulfur hexafluoride permeation tube that needs to be cultivated, and the bottle cap is tightly closed. Then the gas source is connected with the air inlet 5 with a rubber tube, and a specific gas with a certain flow rate can be introduced according to the demand. The gas flows out from the gas outlet 1 through the bottle body. To maintain the air flow environment in the bottle. Then put the whole culture bottle into a water bath or an incubator at a certain temperature for cultiva...

Abstract

The invention discloses a culture bottle for a sulfur hexafluoride permeation tube. The culture bottle comprises a bottle body and a bottle cap, wherein a gas outlet is formed in the top of the bottle cap; a gas inlet is formed in the bottom of the bottle body; and a gas distribution plate is arranged above the gas inlet in the lower part of the bottle body. The culture bottle can meet the requirements of substances which need to be cultivated under the conditions of specific temperature and specific flowing gas. The culture bottle can be placed in a water bath pot or a culture box and is convenient to use. The culture bottle is provided with the specific gas distribution plate, so gasflow in the bottle is uniform and stable.

Description

technical field [0001] The invention relates to a container for microorganism culture, in particular to a sulfur hexafluoride permeation tube culture bottle. Background technique [0002] The technology of sulfur hexafluoride tracer method to measure the intestinal methane emission of ruminants was tried out by the United States in 1992. Releases sulfur hexafluoride at a steady, low rate, a gas with physical properties similar to methane that is excreted with methane during respiration and ventilation in ruminants. Since the emission rate of sulfur hexafluoride is known, when the concentrations of sulfur hexafluoride and methane are measured, the emission rate of methane can be calculated. Sulfur hexafluoride tracer method for measuring ruminant intestinal methane emissions has low investment and operating costs, and can simultaneously measure a large number of animals under production conditions. significance. At present, it is gradually being applied by scientific resea...
