Small cooling water circulation pump——————————————————————
Double layered glass rotating lifting glass reactor——————————————————————
Collecting type magnetic stirrer
——————————————————————
Desktop mini model. Used for cooling and heating components for heat exchange between 2-liter rotary evaporators and various devices. The refrigerant uses HFC (R404). CCA · 20 has safety functions such as self diagnosis, freezer protection timing, freezer high-pressure pressure switch, overload relay, and thermal protection device.
The interlayer of the double-layer glass reactor can be filled with different cold and hot circulating liquids (hot water/hot oil/refrigerant). In a sealed glass container, the reactants are stirred and reacted under normal pressure or negative pressure, and the fully transparent reaction process is clear at a glance. It is an ideal experimental pilot equipment for modern biopharmaceuticals, fine chemicals, and new material synthesis
The DF-101 series collector type constant temperature heating magnetic stirrer is a new type of magnetic stirrer developed by our company. This product has been widely promoted and tested in laboratories of major universities across the country, and has received high praise from users.
