WebHow to balance a centrifuge. Ensure all sample tubes are evenly filled. If additional tubes are required for balancing, fill them with water or a liquid of similar density to the sample, and ensure the mass is balanced to the nearest 0.1 grams. For each tube inserted in the rotor, add a tube of equal weight directly opposite it. WebJun 11, 2024 · I typically plan on 1 100-mm dish of cells per cryovial. Vials should be labeled using a lab marker that will withstand alcohol and liquid N 2. Be careful to include passage/lot numbers when labeling cryovials. 4. Freeze Cells.
