The water bath nitrogen blowing instrument includes a base and a support device, a sample holder and a gas distribution system.

The test tube is fixed in position by a test tube clamp with a spring and a support plate.

Each sample position has a digital number; the gas reaches the gas distribution system through the flow meter, and the guide tube guides the gas into the valve and stainless steel needle at each position, blowing the gas to the sample surface, so that the solvent volatilizes quickly.

According to the size of the test tube and the amount of solvent, each air duct can be independently raised and lowered to a suitable height.

WD-1000
