Introduction In the traditional ultrasonic breaker with probe, the probe is in direct contact with the sample, only one sample can be processed at a time, and the experiment period is long; for multiple samples, the same probe needs to be used repeatedly, which may easily cause sample cross-contamination. Because the depth of the probe inserted into the sample is different each time, the energy distribution of each ultrasound is different, which affects the repeatability and accuracy of the experimental results. In addition, since a closed system cannot be used, the aerosol or foam generated during the ultrasound process will diffuse into the environment, causing potential biological hazards. The non-contact ultrasonic breaker can process up to 16 samples at the same time at a time, and the experiment efficiency is high; there is no need to operate the probe frequently, and each sample is in a separate fully enclosed test tube to avoid cross-contamination; using 4℃ water bath ultrasonic, the energy distribution is even, The effect of ultrasound is complete; the ultrasound parameter settings are flexible, the experimental steps are standardized, the experimental repeatability is good, and the results are highly reliable. XM-26A non-contact shaped DNA interrupter is mainly used for bacterial cell disruption, protein extraction, DNA fragmentation of next-generation sequencing samples, immunoprecipitation experiments, mold spore fragmentation, emulsification, homogenization, accelerated dissolution, and catalytic reaction .

Introduction: Our company has developed a new type of tissue grinder JXFSTPRP-YLS (patented product, counterfeiting must be punished! ZL2019301918692) against the standard of the Ministry of Environmental Protection on chlorophyll a standard "Water Quality Determination of Chlorophyll a Spectrophotometry" HJ 897-2017. Experimental principle: filter a certain amount of sample with a filter membrane to trap algae, grind and break algae cells, extract chlorophyll with acetone solution, and measure the absorbance of the extract at 750nm, 664nm, 647nm and 630nm wavelengths after centrifugation, and calculate chlorophyll a in water according to the formula concentration.
