The application discloses a multifunctional agar pouring bottle, and relates to the technical field of laboratory equipment, comprising a storage bottle, a support, a temperature control sleeve, a pH probe, a temperature sensor, a quantitative pouring device, a magnetic stirring assembly and a gravity ball; the storage bottle is arranged on the support and can move up and down relative to the support; the pH probe is fixedly installed on the inner wall of the storage bottle and located close to the bottom, can measure the pH value of agar medium in the storage bottle, and is made of high-temperature and high-pressure resistant material and can be sterilized together with the storage bottle; the application integrates seven functions of storage, heating, refrigeration, stirring, quantitative pouring, pH sterile measurement and high adjustment, and can complete the whole process operation of agar medium from preparation, sterilization, constant temperature, pH detection to quantitative pouring by using one device, and is perfect in function and high in practicability.

The utility model discloses a pretreatment device for measuring BOD5 (biochemical oxygen demand 5) of water quality, which comprises a square seat support, an adjusting container, a filter and a measuring container are sequentially arranged on a support rod from top to bottom, a pH adjusting pipe group and a pH adjusting flow valve group which are used for adjusting pH are arranged on the adjusting container, and a plugging module is arranged at the bottom of the adjusting container. A determination reagent tube group and a determination reagent flow valve group are arranged on one side of the determination container, and a liquid level sensor for detecting the liquid level is arranged on the determination container. Hcl and NaOH which are added into liquid are controlled through a pipeline and a valve group, the pH is detected through a pH probe, when the pH is qualified, the adjusting container descends, a rod body in the center of the filtering funnel extends into a hole column, the sealing is damaged, and the liquid flows into the lower part for filtering through a plugging module below, and an acetic acid solution and a potassium iodide solution are automatically injected into the measuring container; and the volume of the finally titrated solution is detected through the liquid level sensor.
