Introduction: Ultrasonic bacterial dispersion counter is a bacterial liquid pretreatment instrument based on the principles of ultrasonic dispersion and photoelectric turbidity detection. Compared with the traditional manual dispersion method, the instrument can realize the integration of colony dispersion and turbidity detection faster and better, and at the same time intelligently prompts the dilution volume required to dilute to the standard McKenzie turbidity bacteria suspension. It is an intelligent instrument that efficiently liberates the hands and does not affect the strain activity and drug sensitivity test results. It has high application value in the pretreatment of microbial experiments. working principle The high-frequency electric energy is converted into ultrasonic sound energy by the piezoelectric ceramic transducer, and the ultrasonic sound energy is transmitted to the cuvette by the ultrasonic hammer. Under the premise of not damaging the sample, the ultrasonic wave of the bacteria in the cuvette is uniform. Disperse, and then the light generated by the light source shines on the sensor through the cuvette, the intensity of the transmitted light is read through the sensor, and the sample is compared with the standard material to realize the measurement of the sample’s turbidity based on the sample’s turbidity and algorithm Give the volume of liquid needed to dilute to the target turbidity, and make a preliminary estimate of the number of colonies in the sample. Features: 1. High-efficiency ultrasonic dispersion, turbidity detection, and dilution volume calculation are completed in one step 2. Simple operation. Put the sample in, one-key operation, saving 90% operation time 3. Intelligent Intelligent program control is distributed evenly, real-time reading, avoiding human error 4. High safety and closed experimental environment, reducing the risk of environmental pollution and personnel infection Technical Parameters: Ultrasonic transducer power: 100W Ultrasonic transducer frequency: 40kHz Total times of ultrasound: 0～99 times can be set Ultrasonic working time: 0～99 seconds can be set Ultrasonic interval time: 0～99 seconds can be set Maxwell turbidity display accuracy: 0.01MCF Maxwell turbidity measurement range: 0.00～6.00MCF Maxwell turbidity detection linear range: 0.20～4.00MCF Cuvette sample pool capacity: 1.5～4ML, step width: 0.01ML Maxwell turbidity calibration: multi-point calibration, up to 6 points Dilution function: Automatically generate dosing volume Cuvette features: Fluorosilicone gasket to prevent leakage Storage temperature conditions: -20℃～50℃ Working temperature conditions: 5～35℃ Power-off data storage: 50 groups Power parameters: 220V/50HZ Maximum power consumption: 100W Net weight of the instrument: 3.9kg Appearance size: L270mm* W292mm* H156mm
