Tech Tip 7.2.20
Don’t forget to double check the bottom thickness of your centrifuge adapters to make sure the thicknesses match. The “conical” bottom in thicker and adds ~50 grams in weight. The “round” bottom adapters are much thinner and when these are mismatched can cause a severe centrifuge rotor imbalance.
P.S. people have swapped the adapter bottoms before on accident and didn’t note the thickness difference regardless of the adapter color. This actually did cause a centrifuge imbalance.
