Disclosed are a ceramic membrane for water treatment using oxidation-treated SiC and a method for manufacturing the same. An object of the present invention is to manufacture a ceramic membrane for water treatment, which can be sintered at a low temperature of 1,050° C. or less, in which a SiO.sub.2 oxide layer formed during an oxidation process induces volume expansion so as to prevent defects due to the contraction of a coating layer during general sintering. The ceramic membrane for water treatment using the oxidation treated SiC includes a porous ceramic support layer; and a SiC layer formed on the porous ceramic support layer and including SiC particles on which a SiO.sub.2 oxide layer formed on a surface thereof.

The present invention relates to the field of biological sample testing technology, and in particular, to a testing system. The testing system includes a reagent reaction vessel and a test device. A reagent storage portion and a push rod movable relative to the reagent storage portion are packaged in the reagent reaction vessel, the reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with the test device to separate the sealing element from the reagent storage portion. The test device includes a test cassette, wherein an ejection rod is arranged in the test cassette, and the ejection rod cooperates with the push rod to separate the sealing element from the reagent storage portion. According to the present invention, when the reagent storage portion is inserted, the ejection rod can be quickly pushed to operate, and one operation completes multiple functions such as releasing the reagent, fixing the reagent reaction vessel, and focusing on a test area at the same time, thereby simplifying the reaction steps.

The invention proposes a biological protection membrane which is mounted, in a device for dispensing liquid from a sterile packaging bottle, across a fluid-circulation duct, in the path of the liquid extracted from the bottle and the outside air which is drawn into the bottle. The membrane (7) is made partially of a hydrophilic material and partially of a hydrophobic material. Both the hydrophobic portion (23) and the hydrophilic portion (22) are made from a polymer base, laden in the body thereof with a biocidal agent that is active in the destruction of bacteria by the ionic oxidation effect. The circulation of fluids through the membrane (7) is organised so as to promote the ionic action on the flow of outside air in the hydrophobic material, and to drive the ionically charged active agent by the liquid passing through the membrane in the hydrophilic portion thereof. A porous buffer (8), inserted in the path of the fluids on the inside of the membrane, collects the active agent extracted from the membrane by the remaining liquid not dispensed, passing through the membrane from the outside towards the inside.

A biological sample reaction vessel comprising a reagent storage portion and a push rod movable relative to the reagent storage portion is provided. The reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with an external test device to separate the sealing element from the reagent storage portion. In reaction, the biological sample reaction vessel cooperates with a test cassette. By inserting the biological sample reaction vessel into the external device, the reagent in the reagent storage portion can be released rapidly.
