1. Overview

Model HSHD-2000B Rotary evaporators are mainly used for concentration, crystallization, drying, separation, and coal recovery in industries such as pharmaceuticals, chemical engineering, and biopharmaceuticals. The principle is: under vacuum conditions, constant temperature heating causes the rotating bottle to rotate at a constant speed, forming a large film on the bottle wall and efficiently evaporating the material. The dissolved coal vapor is cooled by an efficient glass condenser and recovered in a collection bottle, greatly improving the evaporation efficiency. It is particularly selected for the concentration and purification of biological products that are prone to decomposition and denaturation at high temperatures.

2.Structural Features

The rotary evaporator of our company gathers the essence of similar products at home and abroad, and the successful practical experience of our company . It has formed 2L, 5L, 10L, 20L, 50L series. The product design follows the principles of efficiency, practicality, and economy, all for the sake of users.

The 2000 series rotary evaporator is the latest generation of intelligent rotary evaporator/device developed by our company after absorbing technology from Swiss company Buqi. It is easy to control and uses a high-performance microcontroller to inform the main control chip last night. Based on the known control object, a dedicated control program is used. The body is beautiful and elegant, and the performance is stable.
