This application report shows how pharmaceutical and cosmetic samples can be measured using the rotational viscometer ViscoQC 100/300 in combination with the PTD 100 Cone-Plate accessory and cone-plate (CPxx) measuring systems. The configuration gives the customer the chance to reduce the required sample volume for a viscosity measurement down to 0.5 mL to 2 mL. In contrast, for a typical rotational viscosity test with standard spindles, a sample volume of 500 mL is required. However, in many cases formulations are only produced in small quantities and include expensive ingredients. Moreover, cone-plate measuring systems provide absolute viscosity determinations for sophisticated and reliable measurements.

McMurtry Spéirling defies gravity using fan downforce
What a fun demonstration. I wonder if they were brave enough to be in the car when it was first turned over. Racing fan cars would be an interesting...
