Pipetting Warm or Cold Beverage Samples Poster
Quality control of beverages like wine and beer, needs precise and accurate pipetting. Pipetting accurately and with high precision can be challenging, particularly if the liquid is viscous, foaming, carbonated or its temperature is different than room temperature. Different techniques are recommended depending on the type (and temperature) of liquid being pipetted.
Some beverages are very challenging to pipette accurately and precisely. Fruit juices with high pulp concentration and mash are challenging to pipette with a standard pipette, as the liquid contains particles that might block the orifice of the pipette tip. Sometimes wide bore pipette tips resolve this issue. Moreover, carbonated liquids like soft drinks and beer need to be degassed before pipetting to ensure accuracy.
