Hair Tissuelyser
LAWSON DHFSTPRP-24 hair homogenizer a special vertical up-down integrated vibration mode is adopted, through the high-frequency reciprocating vibration, impact and shearing of grinding beads (zirconia, steel balls, glass beads, ceramic beads). The ideal grinding effect can be achieved quickly, so that the ground samples have more sufficient, more uniform, better sample repeatability, and no cross-contamination between samples. After grinding, the colloidal gold detection technology can be used for rapid on-site detection of common drugs (morphine, methamphetamine, ketamine, ecstasy, marijuana, etc.) in hair. The detection limits of various drugs have reached the requirements of the "Specifications for the Detection of Hair Samples of Drug-related Persons" issued by the Ministry of Public Security. The product has been widely recognized in the industry since its introduction. The advantages of high sensitivity and high sensitivity are currently very suitable for the hair drug detection equipment used by public security anti-drug law enforcement officers on the spot.

DHFSTPRP Series--Fast Hair Grinder Features:
○ Efficient Grinding—
Realize the rapid on-site grinding of 24 sample hairs at the same time. The grinding equipment has a built-in program controller, which is easy to operate. At the same time, it provides feasible solutions for community drug rehabilitation and special personnel monitoring.
○ Cryogenic Grinding -
Freeze adapters and samples, cryoprotect sample components from being destroyed.
○ Professional Grinding—
The instrument has completed the detection of nearly 1,000 real samples in judicial centers and anti-drug teams in Beijing, Ningbo, Shanghai and other places. The positive detection rate is as high as 99%, effectively avoiding false positive interference caused by taking drugs.
Grindable samples:
| 1. Plant tissue: | roots, stems, leaves, flowers, fruits, seeds, etc. |
| 2. Animal tissue: | Hair, Brain, Heart, Hair, Lungs, Stomach, Liver, Thymus, Kidneys, Intestines, Lymph Nodes, Muscles, Bones, etc. |
| 3. Fungal bacteria: | Yeast, Escherichia coli, etc. |

·Extract nucleic acid/protein
Cryogenic grinding of samples can effectively inhibit nucleic acid degradation and retain protein activity.
·Analysis of active ingredients
Significant differences often exist between isomers of active pharmaceutical ingredients. Cryogenic grinding prevents molecular degradation due to pressure and heat.
Reduce sample volatilization
Cryogenic grinding can significantly reduce the volatilization of the sample and preserve the content of the sample components more completely
Grinding tough/hard samples
For difficult-to-grind samples such as high-toughness plastics, high-strength plastics, and resins, cryogenic grinding can greatly improve the grinding effect and efficiency.
DHFSTPRP-24 hair homogenizer a special vertical up-down integrated vibration mode, through the high-frequency reciprocating vibration of grinding beads (zirconia, steel balls, glass beads, ceramic beads), Hit, cut. Quickly realize the grinding effect, so that the ground samples have more sufficient, more uniform, better sample repeatability, and no cross-contamination between samples.
The principle of colloidal gold:
Colloidal gold detection technology: Colloidal gold is a commonly used labeling technology, a new type of immunolabeling technology that uses colloidal gold as a tracer marker to apply to antigens and antibodies. has its unique advantages. It has been widely used in various biological researches in recent years. Almost all immunoblotting techniques used in clinical use its markers. At the same time, it may be used in flow, electron microscopy, immunology, molecular biology and even biochips.
| The number of operations is large, the effect is good | Efficient and fast work can complete the grinding of 2×24, 2×48, 4×96 samples in 1 minute. Save time and effort, and the difference between batches and batches is small. The extracted protein has higher specific activity and longer nucleic acid fragments. |
| No cross contamination | The sample tube is completely closed during the crushing process, and disposable centrifuge tubes and beads can be used. The sample remains intact in the tube to avoid cross-contamination between samples and external contamination. |
| Easy to operate | 1. Built-in program controller, which can set parameters such as grinding time and rotor vibration frequency; 2. Humanized operation interface. |
| good stability | 1. The vertical oscillation method is adopted, and the grinding is more sufficient and the stability is better; 2. During the operation of the instrument, the noise is less than 55dB, which will not interfere with other experiments or instruments. |
| Convenient low temperature operation | When an ultra-low temperature grinding environment is required, the adapter with the sample can be immersed in liquid nitrogen to cool for 1-2 minutes. After taking it out, it can be moved to the host for quick fixation, and grinding can be started without re-freezing, which is convenient and quick. |
| good repeatability | The same tissue sample was set to the same program to obtain the same grinding effect. The working time is short and the sample temperature does not rise. |
| Applications | Hair grinding, tissue grinding, homogenization, cell disruption, homogenization, material dispersion, preparation, sample mixing, shaking, etc. |
| Throughput | The maximum throughput in 15 seconds can process 24 samples at the same time, including the liquid nitrogen freezing adapter for 12 and 24 positions. |

1. The matching LW kit can be used to quickly, efficiently, stably, and batch extract DNA/RNA proteins from samples.
2. 1Hz=30 revolutions/second / 1Hz=100RPM
3. Conventional adapters can be refrigerated to give samples a cool environment while working. It can be equipped with an adapter with refrigeration, which can be soaked in liquid nitrogen for more than 30 minutes.
4. The noise emission value for the working environment depends on the type of sample and the settings of the grinder. The parameters in the table are in the no-load state.
5. Small samples typically used for DNA and RNA isolation can be prepared in disposable centrifuge tubes. Adapters made of Teflon material can be used to accommodate 5 or 10 disposable sample tubes for cell disruption. Cells and tissues are rapidly and efficiently disrupted in a very short time in the Multi-Sample Tissue Grinder, thus eliminating the need for additional cryogenic refrigeration.
