Dimethyl silicon viscosity tester

YJ-0633ADimethyl silicon viscosity testerThe manufacturing complies with the technical requirements specified in the viscosity determination method 0633 of the Chinese Pharmacopoeia 2025 edition, as well as the specific conditions for pharmaceutical raw materials. This instrument is designed specifically for viscosity testing and consists of a water tank and a controller. The viscosity constant temperature bath provides a stable temperature field and testing platform, and the instrument can also be used as a high-precision bath for other experiments. The biggest feature of this instrument is: full spray coating treatment, durable and long-lasting; Double layer cylinder structure, high-precision temperature controller, accurate temperature control. At present, this product has been widely used in pharmaceutical factories, drug testing institutes, drug research and development, university pharmacy schools, university medical schools and other pharmaceutical industry units.

1、 Main functional features

1. Adopting an intelligent LCD display temperature controller, the temperature control is fast, the response is fast, the overshoot is small, and the temperature control accuracy reaches ± 0.1 ℃.

2. Adopting a hard glass cylinder and an insulated outer cylinder (referred to as a double cylinder), it has good insulation performance and clear observation of the sample.

3. Adopting a desktop and all-in-one design, the instrument has good overall integrity and is easy to use.

4. Equipped with a remote timing button for timing display and control during experiments.

5. Using an electric stirring device, the temperature inside the bathtub is uniform.

6. Adopting a special clamp for 304 stainless steel viscometer, with excellent quality and long service life.

7. Equipped with latex tubing and ear suction balls for convenient user testing.

8. Additional refrigeration units can be selected according to the needs, and they are designed in a split manner, which not only reduces the impact of compressor vibration during testing, but also determines whether to turn on or not based on indoor environmental temperature, achieving energy-saving effects.
