Shanghai Jixin's® Tiss tissue grinder is a special, rapid, high-efficiency, multi-tube uniform system. It can extract and purify the original DNA, RNA, and proteins from various sources, including soil, plant and animal tissues/organels, bacteria, yeast, fungi, spores, paleontological specimens, etc.

This machine is also known as a Multi-sample Organizing Grinder, Quick Organizing Grinder, Multi-sample Organizing Homogenizer, and Quick Sample Homogenization System.

Technical Features

The Shanghai Jixin Tiss-24/48 High-Speed Sample Grinder utilizes a unique vertical up-and-down integrated vibration mode. It grinds samples through the high-frequency reciprocating vibration, impact, and shearing of the grinding beads. During the grinding process, its high-throughput ensures consistency and good reproducibility. Its excellent performance is capable of handling most sample pretreatment tasks without cross-contamination.

The Tiss system boasts broader versatility and efficiency compared to existing sample preparation methods. It eliminates the drawbacks of traditional methods like grinding, homogenization, and ultrasonic treatment, which are labor-intensive, time-consuming, and inefficient. The system can efficiently and rapidly lyse and purify nucleic acids and proteins from various types of samples.

Working Principle:

The high-speed sample grinding machine employs a unique vertical up-and-down vibration mode, which grinds and crushes the sample by utilizing high-frequency reciprocating vibrations, impacts, shearing, and compression forces generated by grinding beads (such as zirconia beads, stainless steel beads, chrome steel beads, tungsten carbide beads, quartz sand, etc.) within a grinding tube or stainless steel jar.

Product Features:

High volume operation, excellent results

Efficiently, 2ml with 48 samples can be milled in just 1 minute. Time and labor-saving, with minimal batch-to-batch and within-batch variations. The extracted protein has higher specific activity, and the nucleic acid fragments are longer.

2. No cross-contamination

Sample tubes remain fully sealed during the crushing process, utilizing disposable centrifuge tubes and beads. The samples are kept intact within the tube, preventing cross-contamination between samples and external contamination.

3. Easy to operate

3.1 Integrated program controller for setting parameters such as grinding time and rotor vibration frequency;

3.2 User-friendly operation interface.

4. Good stability

4.1 Utilizes a top-to-bottom vibration mode for more thorough grinding and enhanced stability.

4.2 The instrument operates with minimal noise, causing no interference to other experiments or equipment.

4.3 The instrument can only rotate when the safety door is closed. If the safety door is opened during the process, it will automatically stop. There is a dedicated emergency stop physical button to prevent accidents.

4.4 Utilizes brushless silent original pulse motor-driven system for stable performance.

Grindable Sample

Plant tissues: roots, stems, leaves, flowers, fruits, seeds, etc.

2. Animal Tissues: Brain, heart, lungs, stomach, liver, thymus, kidneys, intestines, lymph nodes, muscle, bone, etc.

3. Fungi and Bacteria: Yeast, E. coli, etc.

4. Food and Pharmaceuticals: Various foods, tablets, etc.

5. Volatile Sample: Coal, oil shale, wax products, etc.

6. Plastics, Polymers: PE, PS, Textiles, Resins, etc.
