Effect of temperature on pipetting

WebThis can be easily seen when pipetting, by observing how quickly or slowly, the liquid flows when aspirating and dispensing. Pure water, and many aqueous buffers are low viscosity and flow easily. Honey, glycerol and polyethylene glycol are highly viscous and flow very slowly. Master mix is also viscous. Web5. Inconsistent pipetting rhythm Use a consistent pipetting rhythm from sample to sample. Avoid hurrying or rapid operation and get into a rhythm for each step in the pipetting cycle. These five simple techniques alone …
