Parallel viscometer It is an important instrument for determining the viscosity of liquids and the molecular weight of polymers. Its measurement range can reach tens of thousands of centimeters (mm2/S). The advantage is that it is easy to use, and compared to other types of viscometers*. Therefore, Ping's viscometer is widely used in the petroleum industry, chemical industry, and other industrial sectors and scientific research. The total length of the product is about 269mm.Instructions for usageAccording to the structure and shape of the capillary viscometer, it can be divided into four types: Ubbelohde, Finn, Parallel and countercurrent. The viscosity of the sample they measure is kinematic viscosity. It has been widely used in petroleum, chemical, light industry, electromechanical, national defense, transportation, coal, metallurgy and medicine, food, paper, textile, scientific research, institutions of higher learning and other institutions. Correct use of capillary viscometer is very important to ensure product quality and accuracy of scientific research data.
1. Washing and drying.
he viscometer must be washed before use. Generally, it is washed repeatedly with a solvent that can dissolve the residue in the viscometer, then washed with alcohol or gasoline, and then washed with fuming sulfuric acid or potassium dichromate lotion. Soak for 2-3 hours, rinse with tap water after the last, rinse with distilled water, put it in the oven, and heat it up to about 150, or put it upside down at natural temperature for a few days, until it evaporates.
2. Filling with oil.
Connect the small glass tube on the seminal tube with a rubber ball (ear-washing ball) or a syringe with a small mouth, hold the viscometer in your left hand and block it with your index finger With a thick tube mouth, turn the viscometer upside down, extend the long glass tube with capillary tube into the sample, pull the syringe, suck the sample to the second c
