Product Description
The Rotary Evaporator models YR02307 to YR02310 are designed to provide superior efficiency and precision for laboratory applications. These models are equipped with evaporating flasks ranging from 5L to 50L, which allows for a versatile application across various scales of evaporation. With a flange opening of Φ50mm for the YR02307 and Φ125mm for the subsequent models, these evaporators cater to a multitude of requirements and environments.
These rotary evaporators utilize DC stepless speed-regulation, ensuring a smooth and precise control over the evaporation process. The power supply varies from 220V-240V at 50/60Hz to 380V at 50Hz for larger models, which supports a seamless integration into different laboratory setups. Furthermore, the rotation speed varies across models, offering a range from 20 rpm to 140 rpm, depending on the specific requirements. All models come equipped with a powerful 250W motor to maintain optimal performance.
A key feature is the bath material made of stainless steel 304, known for its durability and resistance to corrosion, ensuring longevity even under continuous use. Additionally, the evaporators boast a digital display for temperature readouts within a range of RT~99℃, which allows for precise monitoring and control.
