Pycnometers Made Easy--The Best Way to Measure Density! By Dr. Shawn

In this video renowned educator Dr. Shawn* explains, in the simplest possible way, pycnometers and how to use them to accurately and precisely measure density. Intended for teachers, Mad Scientists, and students. Resources Pycnometers 10 ml -- https://amzn.to/3XLH2Rz 25 ml -- https://amzn.to/4i5JYjh 100 ml --https://amzn.to/4i0PyDs Digital Scales 600g capacity, 0.01g accuracy: https://amzn.to/3Rw9d3g This scale is sufficient for many Mad Scientists. It is inexpensive, but it only has a capacity of 600 g. 2 kg capacity, 0.01g accuracy: https://amzn.to/42lyUc1 This digital scale is an excellent general use option for most Mad Scientists. A 2kg capacity is sufficient for most general lab work, and 0.01 g accuracy is sufficient for many analytic applications. 5 kg capacity, 0.01 g accuracy: https://amzn.to/4jBYr7R This scale should meet all your Mad Science needs. When are you going to need to measure something with a mass approaching 5 kg to an accurate of 0.01g? This is beyond even my wild-eyed machinations! Analytic Balance with OMG-level accuracy: https://amzn.to/42whudG If you're doing serious material analysis, consider this marvel of modern technology. It's an analytic balance with an accurate of 0.0001 g. That is one tenth of one milligram, or two orders of magnitude better than any of the digital balances listed above. It's calibrated and certified and has lots of bells and whistles. What's more, it costs 1/20th of what comparable balances used to cost back when I was starting out in research. What a great time to be alive! Laser Thermometer Infrared Laser Thermometer with a range from negative 58℉ to +1112℉: https://amzn.to/42eFn8x Laser thermometers are essential tools for every Mad Scientist. If you don't have one already, this inexpensive model should be good enough for almost application where you need to know the surface temperature of an object. *Shawn Carlson holds a Ph.D. in nuclear physics from UC Los Angeles.
