KZ-II series multi-sample tissue grinder/high-throughput tissue grinder

1. Large research sample size: 24 samples can be ground within 1 minute

2. Avoid cross-contamination between samples: disposable grinding tubes and grinding beads are used in the grinding process, and the samples are in a fully enclosed state during the grinding process, avoiding cross-contamination between samples

3. Easy to operate: you can directly select the grinding time and grinding frequency to change the grinding conditions

4. Good safety: with cover opening protection device, emergency stop button, little vibration during the operation of the instrument

5. Strong reproducibility: the same batch of samples adopts the same grinding conditions, and the grinding effect is the same

6. Easy to use: it can be centrifuged directly after grinding, no need to change the centrifuge tube

The KZ-II® series tissue grinder of Shanghai Jingxin® is a special, fast, high-efficiency, multi-test tube consistent system. It can extract and purify the original DNA, RNA and protein from any source (including soil, plant and animal tissues/organs, bacteria, yeast, fungi, spores, paleontological specimens, etc.).

Technical features：

Compared with other existing sample preparation methods, the KZ-II® system has the advantages of wide versatility, high efficiency and flexibility. The system avoids the laborious, time-consuming, low-efficiency and many other shortcomings of traditional methods such as grinding, homogenization, and ultrasonic treatment, and can efficiently, quickly and stably lyse and purify nucleic acids and proteins of various types of samples.

This machine is also known as multi-sample tissue grinder, rapid tissue grinder, multi-sample tissue homogenizer, and rapid sample homogenization system.

Grindable samples:  

1. Plant tissue: roots, stems, leaves, flowers, fruits, seeds, etc.

2. Animal tissue: brain, heart, lung, stomach, liver, thymus, kidney, intestine, lymph node, muscle, bone, etc.

3. Fungal bacteria: yeast, E. coli, etc.

4. Food and medicine: all kinds of food, tablets, etc.

5. Volatile samples: coal, oil shale, wax products, etc.

6. Plastics, polymers: PE, PS, textiles, resins, etc.

Operating procedures：

Features：

The KZ-II® series grinder adopts a special three-dimensional integrated vibration mode of up and down and left and right shaking. The sample moves in a three-dimensional shape in the space of a figure of eight, through the high-frequency reciprocating vibration of the grinding beads (zirconia, steel balls, glass beads, ceramic beads) , Impact, shear. Achieve goals quickly. Make the ground samples more sufficient, more uniform, better sample repeatability, and no cross-contamination between samples

1. The number of operations is large and 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, with small differences between batches and within batches. The extracted protein has higher specific activity and longer nucleic acid fragments.

2. No cross contamination

The sample tube is in a fully enclosed state during the crushing process, and disposable centrifuge tubes and beads can be used. The sample is kept in the tube completely to avoid cross-contamination between samples and external contamination.

3. Easy to operate

3.1 The built-in program controller can set parameters such as grinding time and rotor vibration frequency;

3.2 Humanized operation interface.

4. Good stability

4.1 Adopting a special three-dimensional integrated vibration mode of up and down and left and right shaking, the sample moves in a three-dimensional shape of a figure of 8 in the space, the grinding is more sufficient, and the stability is better;

4.2 During the operation of the instrument, the noise is less than 55dB, which will not interfere with other experiments or instruments.

5. Convenient for low temperature operation

When a low-temperature grinding environment is required, the adapter with the sample can be immersed in liquid nitrogen to cool for 1-2 minutes, and then moved to the host to quickly fix it to start grinding. There is no need to freeze again, which saves liquid nitrogen.

6. Good repeatability

The same procedure is set for the same tissue sample to obtain the same grinding effect. Short working time, sample temperature will not rise

Product parameters:

Basic configuration:

Remark：

* The supporting jingxin kit can be used to extract DNA/RNA proteins in samples quickly, efficiently, stably and in batches

* 1HZ=30 rev/sec 1HZ=100RPM

* Conventional adapters can be placed in the refrigerator to provide a cold environment for the samples while working. It can be equipped with an adapter with refrigeration, which can be immersed in liquid nitrogen for more than 30 minutes.

* The noise emission value for the working environment depends on the type of sample and the setting of the grinder. The parameters in the table are in no-load state

* A small amount of samples usually used for DNA and RNA separation can be prepared in disposable centrifuge tubes. Adapters made of polytetrafluoroethylene materials can be used to accommodate 5 or 10 disposable sample tubes for cell disruption. In multi-sample tissue The cell tissue in the grinder is quickly and effectively broken in a very short time, so there is no need for additional low-temperature refrigeration

Experimental case:

Optional accessories：

Shanghai Jingxin is equipped with complete DNA, RNA and protein extraction kits for various samples of animals, plants, microorganisms, etc., which can extract target components quickly, efficiently, stably and in batches
