It is necessary to understand the operation of any device or instrument before useNitrogen blowerHow can we operate correctly when using it!

Firstly, after installing the nitrogen blower, the chassis is supported in a constant temperature water bath. Turn on the water bath power, set the water bath temperature, and the water bath begins to heat up. In order to increase the height of the nitrogen blower, the samples that require transpiration concentration are placed separately on sample positioning racks and supported by trays. The unevenness of the trays and positioning racks can be adjusted according to the size of the training sample test tubes. When the flow meter needle valve is opened, nitrogen gas reaches the distribution plate through the flow meter and gas pipeline, and after distribution, it is sent to the needle valve tubes above various grades (installed on the distribution plate). After adjusting the needle valve tube through online calibration, nitrogen gas is blown towards the liquid sample test tube through the needle valve tube and needle. The locking nut can be adjusted to slide the needle valve tube up and down, adjust the needle height, and make sure that the sample surface is rippled without splashing. Place the nitrogen blower in a water bath until transpiration concentration is complete.
