The product warranty period is 12 months. Problems caused by artificial damage or mis-operation are not covered under warranty.

● Do not press too hard on the joint of the grinder and pestle.

● When using the TGrinder to grind the sample, the volume of the lysis buffer is recommended not to exceed 150 μl, so as to prevent unnecessary injury caused by the splashing of the lysis buff er out of the centrifuge tube during the grinding process.

● The grinder is a motor-driven instrument, which should not frequently be used to grind hard samples, helping prevent damage to the joint area.

● Operate the grinder intermittently, and keep pressing the grinder switch for 3-5 s to avoid the melting of pestle and plastic consumables caused by the generation of heat from friction.

● Avoid immersion and contact with water and other liquids when the instrument is in use, that helps prevent short-circuit.

● The body of the instrument is not resistant to strong acid, strong alkali and most organic solvents. Salty liquids also have certain corrosive eff ects on metals in the equipment. If

the instrument is inadvertently exposed to the above chemicals, please immediately wipe it clean with water.

● First plug the power adapter into the instrument connector, and then plug it into the power socket. The pestle should not touch any part of human body when working, so as

to avoid personal injury. All product accessories (power supply, pestle) can only be used with this instrument and not with other instruments without authorization. In case of any

● This device is suitable for grinding and breaking all kinds of plant tissues, including roots,stems, leaves, flowers, fruits, seeds and other samples.

● Suitable for grinding and breaking of all kinds of animal tissues,including brain, heart,lung, stomach, liver, thymus, kidney, intestine, lymph node and muscle samples.

● It can be used for homogenization.

In contrast to the traditional nitrogen grinding for RNA/DNA extraction, TGrinder can grind 1-100 mg of tissue samples efficiently in a 1.5 ml centrifuge tube. The crushing is sufficient, the effect of homogenization is good, and the loss of samples during operation is reduced. With a small size, light weight and a low power consumption, this grinder is widely used for grinding, crushing and homogenizing animal tissue samples such as brain,heart, lung, stomach, liver, thymus, kidney, intestine, lymph node and muscle,and plant tissue samples such as root, stem, leaf, fl ower, fruit and seed. The OSE-Y50 has a built-in brushless motor to drive the grinding pestle, with a speed regulation function, which can flexibly handle various sample types.

● Plastic and metal grinding pestles are available for various animal and plant materials.

● Easy to use and equipped with a sterilized box of grinding pestles that can be loaded by direct insertion.

● The removal box can be used to unload the pestle with one press, which is convenient to operate and avoids contamination.
