ZLNS-1 vacuum centrifugal concentrator is a laboratory commonly used equipment developed by our company. It can also be equipped with a cold trap. In order to test the actual working effect of the instrument, we will now test this instrument. Today's experiment is concentrated milk and water.
We chose a brand of milk, pour the milk into a 1.5ml centrifuge tube and pour 1ml.
The mark is indeed 1 ml, (⊙o⊙)... It is not very clear.
Put the milk in the rotor of the concentrator. The standard rotor is 16*1.5ml and 16*7ml.
Look at it from another angle.
Cover and prepare for concentration.
Run the instrument, start vacuuming and heating
The vacuum gauge has been shown to be in a vacuum state and the vacuum is continuously drawn.
The temperature is set at sixty degrees, and the temperature inside the pot is gradually rising.
The temperature has reached the set temperature, and now we continue to concentrate on this state for half an hour. What is the effect?
Ok, the time has come. After half an hour, the capacity of the sample milk is still four-fifths of the original, and it is condensed by one-fifth.
In order to make the effect more obvious, we will use the 7ml test tube to look at it this time. The samples prepared this time are milk and water.
Continue the above steps to concentrate, this time of concentration is 3 hours.
The effect after concentration, as shown in the figure, is one-third of the sample chamber.
The water and milk samples were essentially flat.
ZLNS-1 vacuum centrifugal concentrator is now priced at 13800
