Precise application of automatic sample processing system in nucleic acid detection system
Director: Today, the department has 2,000 samples to be tested for nucleic acid. The results are required within 24 hours. Time is relatively tight. Thank you for your hard work today.
Xiao Wang: 2000 samples? Are you sure it can be done within 24 hours?
Xiao Zhang: 2000 samples? What are you afraid of? Yesterday, I just arrived at an automatic sample processing system, which is adapted to a 96-channel nucleic acid extractor. The reagent dispensing is automated, 15 times faster than manual dispensing, and it is no problem within 24 hours!
Is your experiment efficiency really high? Especially in the face of large and urgent experiments, manual operations are still selected in the most basic and most frequent steps of pipetting, dispensing, and dilution. Obviously, the results are not ideal. The importance of pipetting is that its accuracy and precision have a greater impact on the experimental results; if the sample size is large, the experimenter will need to spend a lot of operating time, not only the efficiency is low, but also fatigue errors are prone to occur, leading to the experiment failure.
Experimenter with 5 years of operating experience:
After dispensing 20 consecutive 96 well plates, the probability of error is 50% (about 0.5 hours)
After dispensing 50 consecutive 96-well plates, the probability of error is 100% (about 2 hours)
With the continuous improvement of inspection requirements for sample processing throughput and the reliability of test results, automated diagnostic equipment based on high-throughput micro-liquid processing technology is an inevitable trend in the development of clinical laboratory automation.
Yongyue Medical took advantage of the trend. The doctoral team independently developed and produced a fully automatic sample processing system. At the current stage when reagent dispensing is still dominated by manual dispensing, when hospitals and disease control are conducting large-scale population nucleic acid testing, this device can greatly reduce the errors caused by manual intervention and significantly improve the speed.
Unique process design, fast and accurate liquid dispensing
Using a unique peristaltic pump design, the liquid transfer is realized by continuously squeezing the rubber tube, with a minimum liquid dispensing accuracy of 0.5 μL, which has high accuracy. In addition, the mode and range can be adjusted according to the needs of the experiment to achieve the purpose of rapid and accurate liquid dispensing. It has become an ideal equipment for repeated liquid dispensing in the laboratory.
One-click cleaning of pipes, making experiments more convenient
The 8-gang silicone hose has a long service life, can be dispensed 200,000 times, and the pipeline can be disassembled and sterilized or replaced. The equipment has built-in pipe cleaning and rinsing functions. Before and after each experiment, there is no need to replace the pipe. One-click operation can achieve the purpose of cleaning. This avoids the cumbersome replacement of the pipette tip and saves the cost of consumables.
Convenient operation and enhance user experience
The 7-inch color touch screen is set up and easy to operate. The manufacturer provides video teaching from unpacking to software operation. Any operator can immediately control it, and it can be used handily with almost no training. Built-in template function, repeated experiments can save parameters, the same experiment can be opened directly by clicking the template, saving parameter setting time. The MDS-96 automatic sample processing system is small and compact, suitable for use in any position in the laboratory, and can be placed on the laboratory bench, fume hood, ultra-clean table, etc.
The MDS-96 fully automatic sample processing system realizes automated, high-throughput and precise liquid dispensing, which saves manpower and avoids experimental sample loading errors. It is an artifact of large-scale nucleic acid detection systems at this stage, faster than manual liquid dispensing. 15 times, it can be adapted to 96-well PCR instrument and 96-channel nucleic acid extractor on the market to realize semi-automation of RNA extraction step.
