Product Description
The Hotplate Magnetic Stirrer, models YR02953 and YR02954, is designed to provide exceptional stirring capabilities combined with precise temperature control, making it a vital asset for any laboratory setting. With a robust build and advanced features, this equipment caters to a wide range of mixing and heating requirements.
The top plate of this stirrer is crafted from white ceramics, ensuring excellent thermal performance and chemical resistance. Depending on the model, the stirrer features a square plate differing in size: 140 × 140 mm for the YR02953 model and a larger 180 × 180 mm for the YR02954. This variety in dimension accommodates diverse experimental needs, from compact to extensive sample processing.
The stirring range of 100 to 1800 rpm, coupled with a stirring speed accuracy of ±1 rpm, ensures that the sample’s homogeneity is achieved efficiently across four positions. The digital display facilitates easy monitoring and control of the stirring speed, enhancing user convenience.
Another significant feature is the temperature control, extending from ambient conditions up to 400°C with a top plate maximum temperature of 325°C. The precision of ±1 degree is maintained through PID temperature control, ensuring reliable and consistent results. The temperature is displayed digitally, further enhancing precision with easy readability.
