One part of monochromatic light is absorbed by the specimen, and the other part shines on the photodetector through the specimen. Photodetectors convert optical signals of samples with different intensities into corresponding electrical signals. After pre-amplification, logarithmic amplification and analog-to-digital conversion, the electrical signal is sent to the microprocessor for data processing and calculation. Finally, the results are displayed by the monitor and printer.
The microprocessor of the autoclave also controls the movement of the mechanical driving mechanism in the X direction and the Y direction through the control circuit to move the microplate, thus realizing the automatic sampling and detection process. However, some autoclaves use manual moving microplate for detection, so the mechanical driving mechanism and control circuit in the direction of X and Y autoclaves are omitted, which makes the instrument smaller and simpler in structure.
Autoclave microplate is a kind of transparent plastic (structure: synthetic resin, plasticizer, stabilizer and pigment) specially packaged in advance, which is used to place the sample to be tested. There are rows of small holes with uniform size, and corresponding antigens or antibodies are buried in the holes. Each hole in the microplate can hold several milliliters of solution. Its common specifications are 40-well plate, 55-well plate and 96-well plate. Different instruments use different orifice plates. Autoclave is suitable for medical and health undertakings, scientific research, agriculture and other units to sterilize medical instruments, dressings, glassware, solution culture media, etc. This is an ideal device. Portable autoclave is a necessary inspection equipment for QS and HACCP certification in food factories and drinking water plants. The autoclave has the functions of self-inspection, automatic filter selection, vibrating plate and communication. Autoclave has two functions for users to choose: single and double wavelength detection, absorbance and qualitative and quantitative analysis.
The patented and verified optical path system of autoclave ensures accurate results and meets the requirements of different fluxes. Mature and reliable performance comes from the built-in self-diagnosis program. At the start-up stage of the instrument, the built-in self-diagnosis program will comprehensively detect the position of the microplate and the stability of the optical path components. Pressure steam sterilizer, also known as autoclave, can be divided into portable sterilizer and vertical sterilizer. A device for heating water with electric heating wires to generate steam and maintain a certain pressure. It mainly consists of a sealed barrel, a pressure gauge, an exhaust valve, a safety valve and an electric heating wire. Autoclave is a kind of high-pressure container that uses pressure higher than normal pressure to raise the boiling point of water to a high temperature above 100℃ to sterilize liquids or utensils. The color liquid crystal display and operation keyboard on the big screen of the autoclave are easy to use and can be used to store three commonly used programs. Data and programs can be stored in the instrument or on a U disk through the USB interface provided by the instrument.
The internal software of autoclave is powerful, and there are many interface languages including Chinese. Functions include: setting the layout of microplates, displaying test results, and performing data processing, including dynamic analysis, data preprocessing, curve fitting, data classification, quality control, etc. In addition, the autoclave can also use powerful software for instrument control and data result processing.
