LAWSON21-1200
Non-Contact Ultrasonic Crusher
Standard sample processing volume includes 20 holes of 5ml, 15 holes of 10-15ml, and 1 hole of 500-1000ml flask.

Non-contact Ultrasonic Crusher LAWSON21-1200 adopts an isothermal and non-contact method to crush, homogenize, and mix samples, which is suitable for sterile, ultra-microscale and high-capacity crushing. Non-contact ultrasonics are used to disrupt samples through containers. For laboratories that process multiple samples per day or valuable samples, it has the advantages of high-throughput processing, low sample loss, and no cross-contamination.

Product Introduction

Non-Contact Ultrasonic Crusher LAWSON21-1200 adopts an isothermal and non-contact method to crush, homogenize, and mix samples, which is suitable for sterile, ultra-microscale and high-capacity crushing. Non-contact ultrasonics are used to disrupt samples through containers.

Working principle:
Non-Contact Ultrasonic Crusher adopts a design that installs the ultrasonic generator at the bottom of the water tank. In traditional probe-type ultrasonic cell disruptors, the microfluidic phenomenon caused by ultrasound can only occur in the area near the probe. However, the non-contact ultrasonic cell disruptor installs the ultrasonic generator at the bottom of the water tank, so that the entire water tank is within the range of ultrasound, and the ultrasonic effect is widely and evenly distributed, reducing the formation of foam. During the experiment, the automatic continuous rotation of the independent sealed centrifuge tubes by the non-contact ultrasonic cell disruptor makes the distribution of ultrasonic energy more uniform. In the experimental process, the samples are placed in separate fully sealed centrifuge tubes, and there is no cross-contamination between samples, avoiding the spread of aerosols.

In the experimental process, the samples are placed in separate fully sealed centrifuge tubes, and there is no cross-contamination between samples, avoiding the spread of aerosols.

Advantages:
Traditional probe-type ultrasonic cell disruptors come into direct contact with the sample, leading to metal ion contamination, and can only handle one sample at a time with a long experimental cycle. For multiple samples, the same probe needs to be reused, which can easily cause cross-contamination between samples. Moreover, since the depth of each probe insertion is different, the distribution of ultrasonic energy during each use is also different, affecting the repeatability and accuracy of experimental results. In addition, since a closed system cannot be used, the aerosols or foams generated during ultrasonic processing will spread into the environment, posing a potential biological hazard. The non-contact ultrasonic cell disruptor can simultaneously process 4-32 samples, with high experimental efficiency; there is no need to frequently operate the probe, and each sample is in a separate fully enclosed test tube, avoiding cross-contamination. With a 4°C water bath, the ultrasonic energy is evenly distributed and the ultrasonic effect is complete. The ultrasonic parameters are flexible, and the experimental steps are standardized, with good experimental repeatability and high reliability of results.

Important Notes
1. Choose an appropriate probe based on the sample volume being processed. A dedicated wrench is required for changing the probe;
2. When the AMPLITUDE knob is turned on, the probe should not be exposed to air. In special circumstances (testing the probe), it should not exceed 10 seconds;
3. Prepare an ice box before use. The sample must be placed in an ice bath during processing, and the sample concentration should not be too high.
