![]() Typically, you use T-bar spindles for these products.ĭo you have any other tips for taking viscosity? Leave a comment below. Brookfield calls this type of viscometer a Heliopath. creams & gels) you need a movable viscometer so the reading is more reflective of the static product. Since some products get thinner as you apply a force (e.g. Use “drilling” viscometer for non-Newtonian fluids. Ideally, you want to use a spindle and speed that gives a reading of 50.ģ. 1 pascal second is equal to 1000 cps, or 1 Pa-s. ![]() We assume you are converting between centipoise and Pascal-second.You can view more details on each measurement unit: cps or Pa-s The SI derived unit for dynamic viscosity is the pascal second. How many cps in 1 Pa-s The answer is 1000. A Brookfield viscometer has a range from 0 to 100 (at least the old analog ones did) which was then multiplied by a factor depending on spindle & speed. More information from the unit converter. Get spindle/speed combination that puts target viscosity at middle of the range. If you haven’t set a target viscosity find a competitive product that looks like what you want.Ģ. ![]() But lotions, gels, and other products vary. Body wash/shampoo have viscosity ranges from 5000 - 20,000 cps. This is more dependent on the marketing of the product than the formulating. The key things to consider when picking a spindle and speed.ġ. Specifically, they wanted to know what parameters go into making a viscosity range and picking a spindle.įirst, see this post for a quick primer on fluid viscosity see this post we did and then look at what the viscometer manufacturer Brookfield has to say about what is viscosity. On another discussion group someone asked how to determine the correct viscosity range and spindle for your formulas. ![]()
