In forward pipetting, an exactly set volume of liquid is aspired to the tip and then it is delivered to a new vessel. This is achieved by creating vacuum by means of the vertical travel of a metal or ceramic piston within an airtight sleeve.
A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors. Recommendations for corrective pipetting actions, made by various US governmental agencies and ergonomics experts, are presented below.
Reverse pipetting is a technique to dispense a measured quantity of liquid by means of air displacement pipette.The technique is mainly recommended for solutions with a high viscosity or a tendency to foam: [1] as it reduces the risk of splashing, foam or bubble formation.

There are several methods available to isolate and amplify cells for single-cell analysis. Low throughput techniques are able to isolate hundreds of cells, are slow, and enable selection. These methods include: Micropipetting; Cytoplasmic aspiration; Laser capture microdissection.
In chemistry, coprecipitation (CPT) or co-precipitation is the carrying down by a precipitate of substances normally soluble under the conditions employed. [1] Analogously, in medicine, coprecipitation (referred to as immunoprecipitation) is specifically "an assay designed to purify a single antigen from a complex mixture using a specific antibody attached to a beaded support".
Moving-boundary electrophoresis was developed by Arne Tiselius in 1930. [3] Tiselius was awarded the 1948 Nobel Prize in chemistry for his work on the separation of colloids through electrophoresis, the motion of charged particles through a stationary liquid under the influence of an electric field.
