Abstract:
본 발명은 각종 시험분석에 사용되는 시험관에 관한 것이다. 본 발명의 시험관은, 시험관 몸체의 높이방향 내주면 일측에, 하나 이상의 돌출부가 내주면 원주를 따라 링의 형상으로 형성된 구조를 가짐에 기술적 특징을 가지고 있다. 본 발명의 시험관은, 시험관에 담긴 분석대상용액을 증발시키거나 반응시키는 등의 경우, 용액에서 거품이 과다하게 발생하거나, 용액이 튀면서 내주면을 따라 상승하여 시험관 상부 내주면에 고형분이 부착 또는 용액이 외부로 유출되는 현상이 상기 돌출부에 의해 방지 또는 최소화됨으로써, 전처리 시간을 현저히 단축할 수 있는 장점이 있다. 시험관, 아미노산, 분석, 전처리
Abstract:
PURPOSE: A test tube is provided to reduce manufacturing costs, energy and water waste by reducing evaporation time with a protrusion part of a ring shape which is protruded according to the circumference of the inner circumference. CONSTITUTION: A test tube includes a protrusion part(E) formed according to the inner circumference on the inner circumference. The protrusion part is protruded from the inner circumference by a recess which is formed on the test tube. The protrusion part is a protruding member of a ring shape which is coupled on the inner circumference of the inner circumference. A height of the protrusion part is 10 ~ 20 % of the height of the test tube.

Abstract:
PURPOSE: To promote the secretion rate of digestive enzymes from anaerobic microbes in ruminant stomachs, thereby increasing the amount of milk production. CONSTITUTION: The agent is prepared by (a) mixing a non ionic surfactant and an acrylic acid polymer; (b) mixing the mixture with an alkaline ionic water(pH 11) at volume ratio of 1 to 10 to prepare a diluted solution; and (c) mixing the diluted solution with additives at rate of 1 to 1 (v/w). The feed composition is characterized in that it comprises 0.001 to 20 wt.% of the agent regarding the total weight of the feed composition.
Abstract:
PURPOSE: A kit for measuring rumen digestibility is provided, thereby easily measuring the rumen digestibility without surgery operation, and reducing the cost for measuring rumen digestibility. CONSTITUTION: The kit for measuring rumen digestibility comprises a hydrolysis enzyme having standardized titer, antibiotics and a buffering material, wherein the standardization is carried out by mixing enzymes to have the condition consisting of the same distribution, kinds and titers of enzymes as the real rumen; the hydrolysis enzyme is one or more selected from alpha-amylase, beta-amylase, amyloglucosidase, cellulase, hemicellulase and protease; the antibiotics is one or more selected from penicillin-G, streptomycin and chloramphenicol; and the buffering material is sodium bicarbonate.
