Product Introduction
High temperature and high pressure digestion colorimetric cell: It is an integrated digestion colorimetric cell used in industrial environmental monitoring instruments for sample digestion reactions and receiving light irradiation. It has the characteristics of high strength, high transparency, and high sealing at room temperature or high temperature strong acid. Its structure is an integral pipe consisting of a longitudinal upper pipe, a transverse pipe, and a longitudinal lower pipe connected in sequence and continuously connected. The transverse pipe also serves as a light channel, and the pipe walls at both ends of the light channel are equipped with flat transparent windows. The diameter of the integral pipe is much smaller than the length of the transverse pipe. The upper end of the longitudinal upper pipe and the lower end of the longitudinal lower pipe are both threaded interfaces, and the inner diameters of the two longitudinal pipes are reduced at the interface. The total volume of the three digestion colorimetric tanks is significantly reduced compared to traditional straight tube digestion tanks, with high pressure resistance, small trial volume, no residual solution flowing through the tubes in the tank, complete digestion reaction, and high detection accuracy.
Product advantages
The digestion tube uses quartz glass, which has high strength and transparency. The quartz glass light guide column is used as the light guide medium, which can shorten the light transmission distance, reduce the loss of light during the transmission process, and improve the service life of the lamp source.
