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.
During repetitive tasks such as pipetting, maintaining body positions that provide a maximum of strength with the least amount of muscular stress is important to minimize the risk of injury. A number of common pipetting techniques have been identified as potentially hazardous due to biomechanical stress factors.
Once a suitable tip is attached to the pipette, press its knob to the first stop. Dip the tip into the solution to a certain depth according to the volume set.; Afterwards slowly release the pipette knob till the starting position.

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.
Positioning test probes onto a microchip Electrophysiological setup. Micromanipulators are used to position microelectrodes. Movement reduction can be performed by mechanical levers, hydraulically using pistons of different diameters connected by tubing containing non-compressible fluid, electronically using stepper motors or linear actuators, or combinations of techniques in one instrument.
Microcontact printing (or μCP) is a form of soft lithography that uses the relief patterns on a master polydimethylsiloxane (PDMS) stamp or Urethane rubber micro stamp [1] to form patterns of self-assembled monolayers (SAMs) of ink on the surface of a substrate through conformal contact as in the case of nanotransfer printing (nTP).

Microwave digestion is a chemical technique used to decompose sample material into a solution suitable for quantitative elemental analysis. [1] It is commonly used to prepare samples for analysis using inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectroscopy, and atomic emission spectroscopy (including ICP-AES).
