  Viscometer suggestion

  Posted by Mariza on July 26, 2018 at 3:08 pm

  Hello,

  I am formulating face creams and I want to measure their viscosity. 
  Therefore, can anyone suggest me a cheap viscometer/rheometer that can do the job?

  Thanks in advance

  I’m afraid the words cheap and rheometer can’t be used in the same sentence.

  An used brookfield on ebay will be your best option. i wouldn’t waste money on those cheap chinese. Brookfield is the standard.

  Hello DAS,

  Thank you for your suggestion. 
  Have you heard of Mettler RM180 Rheomat, do you think it can be useful?

  It is a well known brand, but I still think brookfield is your best choice. For example, if you read any COA from a raw manufacturer most likely the viscosity test is made with a brookfield.

  Mettler is an expensive brand, so brookfield would be the best choice.

  On the cheap you can get a 50 ml or larger syringe, drill a larger exit hole
  make a suitable device that holds it facing down, and place a weight on the plunger.
  See how long it takes to empty trough the exit hole.
