　　top-mounted stirrerAs a basic equipment in the laboratory, it may seem simple, but there are still many precautions to be taken in actual use. Proper and standardized operation can extend the service life of equipment. Stainless steel stirring blades are used for mixing salt solutions, which contain chloride ions. If not cleaned in a timely manner after use, rust stains and corrosion may occur after a period of time. Research has shown that when the chloride ion content is greater than 25ppm, stainless steel will undergo stress corrosion, pitting corrosion, and intergranular corrosion. So in the experiment, it is important to pay attention to timely cleaning and maintenance in order to extend the service life of stainless steel stirring blades. Of course, PTFE stirring blades can also be chosen.

　　top-mounted stirrerFor large capacity mechanical mixing equipment, product features:

1. Stainless steel card head, durable and long-lasting

2. Digital display model, mixing has three modes: forward rotation, reverse rotation, and alternating forward and reverse rotation

　　top-mounted stirrerThe relationship between stirring amount and viscosity: Generally, the stirring amount of a mixer is based on water as a reference material. In practical applications, the sample will have different viscosity ranges, and the increase in viscosity and stirring amount is not completely proportional. It is not possible to choose to increase the viscosity by 10 times and directly use it by reducing the stirring amount by 10 times.

Selection of mixing blade: The shape of the mixing blade directly affects the mixing effect. When the viscosity of the sample is relatively high, choose an anchor type stirring blade, which can continuously stir the sample near the container wall during stirring, to prevent the sample from sticking to the container wall and unable to mix. If the sample is easily suspended on the surface of the liquid, a descending type can be chosen. For samples that are prone to precipitation, an upward stirring method can be used to continuously stir the sample.

　　top-mounted stirrerWhen the load changes during motor operation cause changes in current, the output of motor torque will be calculated. But this torque does not have any form of proportional relationship with the viscosity of the sample. The overall output torque of the mixer will increase with the increase of sample viscosity, but there is no proportional relationship. Therefore, torque display cannot be used as a viscosity meter. If it is necessary to measure the viscosity of the sample, specialized viscosity measurement equipment needs to be equipped.

If the sample is corrosive and conventional stainless steel impellers cannot meet the application requirements, PTFE coated impellers can be selected. However, PTFE material is relatively soft, so attention should be paid to the operating speed during use.
