Meat identification device

　　Meat identification devicePrecise protection of food safety

1、 Brief introduction:

　　Meat identification deviceIt is an efficient and convenient food testing device designed specifically to identify the authenticity of meat. It can detect various animal derived ingredients such as pork, beef, lamb, horse meat, donkey meat, duck meat, chicken meat, etc. Can quickly and accurately detect DNA components in meat and meat derived samples, ensuring the authenticity and reliability of the meat consumed. Its high sensitivity and low error rate ensure the accuracy of the detection results, providing professional detection services for various testing units.

2、 Working principle:

The real and fake meat detector uses real-time fluorescence quantitative PCR technology to detect and amplify DNA in meat samples using specific primers and probes.

The following are its detailed work steps:

1. Sample preparation: Homogenize the meat sample and extract DNA.

2. PCR reaction: Specific primers, probes, and sample DNA are added to the reaction tube and placed in a detector for PCR amplification.

3. Real time detection: During the PCR amplification process, the instrument monitors the DNA amplification status in real time through fluorescence signals and generates amplification curves.

4. Data analysis: Based on the fluorescence signal intensity and amplification curve, determine whether the sample contains specific DNA sequences to determine the authenticity of meat.

3、 Instrument features:

1. Small size, light weight, easy to carry, compatible with 0.2PCR single tube, eight tube, and can simultaneously detect 16 samples;

2. Adopting the American MARLOW customized Peltier module high-level semiconductor chip and the new generation of semiconductor temperature rise and fall technology, the fast temperature change rate can reach 7 degrees per second, and the service life can reach one million cycles;

3. The adopted lighting detection and processing technology automatically adjusts the fluorescence background, improves the sensitivity and signal-to-noise ratio of the fluorescence signal, and obtains better results;

4. 13S two channel fast lighting, stable fluorescence acquisition signal, reducing delay error;

5. Adopting maintenance free long-life LED light source, no need for replacement, independent fluorescent channel, and less crosstalk between different channels;

6. Constant current control circuit, smooth power output, extended Peltier life, and improved temperature control accuracy;

7. It has protection functions such as overcurrent and over temperature;

8. Powerful software analysis capabilities, including quantitative analysis, melting curve analysis, gene typing, etc. The analysis software has been upgraded to support software customization for different industries;

9. Comes with a 10 inch color touch screen control.
