The LAWSON DHFSTPRP-CL48 Freezer is a special, fast, efficient, multi-tube, consistent system. It can extract and purify raw DNA, RNA, and proteins from any source, including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, paleontological specimens, and the like.
Three key elements of sample processing:
High-efficiency grinding - processing up to 192 samples in one batch
Low temperature grinding - grinding temperature can be customized

Program can be stored
save time and energy
High speed and convenience
High-throughput sample processing
Good experimental repeatability
The sample is completely closed without cross-contamination
Low noise ≤55db: Use brushless frequency conversion motor
No liquid nitrogen operation required, high safety

Stainless steel cavity, easy cleaning and disinfection
No regular maintenance
1. Plant tissue: roots, stems, leaves, flowers, fruits, seeds, etc.
2. Animal tissues: brain, heart, lungs, stomach, liver, thymus, kidneys, intestine, lymph nodes, muscles, bones, etc.
3. Fungal bacteria: Yeast, E. coli, etc.
4. Food and medicine: various types of food, tablets, etc.
5. Volatile Samples: Coal, oil shale, wax products, etc.
6. Plastics, polymers: PE, PS, textiles, resins, etc.
Extract nucleic acids/proteins
Cryomilled samples can effectively inhibit nucleic acid degradation and retain protein activity
Analysis of medicinal ingredients
There are often significant differences between isomers of pharmaceutical active ingredients. Cryogenic grinding prevents molecules from degrading 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 more completely
Grinding toughness/hard samples
For difficult-to-abrasive samples such as high-toughness plastics, high-strength plastics, and resins, cryogenic grinding can greatly improve the grinding effect and efficiency.
LAWSON-48D Liquid Nitrogen Freeze Grinding Machine uses a special vertical up and down one-piece vibration mode, through the high-frequency reciprocating vibration, impact, shearing of the grinding beads (zirconia, steel ball, glass beads, ceramic beads). Fast implementation. Makes the milled sample more full, more uniform, better sample repeatability, and no cross-contamination between samples.

Precautions before use:
1. The matching LW kit can be used to quickly, efficiently, stably, and bulkly extract DNA/RNA proteins in samples.
2. 1Hz=30 revolutions/sec / 1Hz=100RPM
3. Conventional adapters can be placed in the refrigerator to give the sample a cold environment at work. Can be equipped with a cooling adapter, can be soaked in liquid nitrogen for more than thirty minutes.
4. The noise emission value for the work environment depends on the type of sample and the settings of the mill. The parameters in the table are empty.
5. A small amount of sample, usually used for DNA and RNA separations, can be prepared in disposable centrifuge tubes. Adapters made of PTFE can be used to hold 5 or 10 disposable sample tubes for cell disruption. In multiple sample tissues The cell tissue in the mill is broken down quickly and efficiently in an extremely short period of time, eliminating the need for additional cryogenic refrigeration.
