Abstract

The invention discloses a spectrophotometer with a mixer. The spectrophotometer comprises a spectrophotometer body, wherein a sample feeding tube with a constant-flow pump is arranged in the body, and the sample feeding tube is connected with a cuvette; a fixed seat is arranged in the spectrophotometer body; a sample seat in movable fit connection through a slide bar is arranged on the fixed seat; a clamping port capable of arranging the cuvette is formed in the sample seat, and an optical path hole is formed in the corresponding detection optical path; a vibration motor is connected to the sample seat; a material layout tube is further arranged on the cuvette. According to the device, one or more sample feeding tubes and the corresponding constant-flow pumps can be used for sucking different needed test liquids according to test needs, and laid out in the cuvette, and the vibration motor is capable of rapidly reacting reaction solution in the cuvette and immediately detecting. Therefore, the device disclosed by the invention has the advantages of being suitable for automatic sample feeding and short-time chemical reaction detection tests, and capable of adequately mixing a sample without the need of manual intervention during a mixing process.

Description

technical field [0001] The present invention relates to a spectrophotometer device, in particular to a spectrophotometer with a mixer. Background technique [0002] A spectrophotometer is an instrument that uses spectrophotometry to quantitatively and qualitatively analyze substances. This instrument is an essential inspection equipment for food factories and drinking water factories to apply for QS and HACCP certification. Spectrophotometry is a qualitative and quantitative analysis of the substance by measuring the absorbance of the measured substance at a specific wavelength or within a certain wavelength range; the commonly used wavelength range is: (1) the ultraviolet region of 200-400nm (2 ) 400-760nm visible light region, (3) 2.5-25μm (4000cm<-1>~400cm<-1> in terms of wave number) infrared light region; the instruments used are ultraviolet spectrophotometer, visible light spectrophotometer (or Colorimeter), infrared spectrophotometer or atomic absorption ...
