   For example, a motorized pipette controller can aid liquid aspiration or dispensing using volumetric pipettes or graduated pipettes; [14] a tablet can interact in real-time with the pipette and guide a user through a protocol; [15] and a pipette station can help to control the pipette tip immersion depth and improve ergonomics.

   These tips have a little piece of foam plastic in the upper conus to prevent sample aerosols contaminating the pipette. In general, all tips are stored in 8 × 12 boxes for 96 pieces in an upright position. The spacing of tips in these boxes is usually standardised for multichannel pipette compatibility from a number of different suppliers.

   en.wikipedia.org/wiki/Graduated_pipette

   There are two types of pipettes that differ based on where the markings are located in reference to the pipette tip. These are Mohr pipettes and Serological pipettes, and they differ only by the position of the first graduation mark, nearest the tip of the pipette. [3] A Mohr pipette is designed for use as a drain-out pipette. It has a straight ...

5. Positive displacement pipette - Wikipedia

   en.wikipedia.org/wiki/Positive_displacement_pipette

   Positive displacement pipettes are a type of pipette that operates via piston-driven displacement. [1] [2] Unlike an air displacement pipette, which dispenses liquid using an air cushion in the pipette tip, the piston in a positive displacement pipette makes direct contact with the sample, allowing the aspiration force to remain constant.

   Move the pipette to the receiving vessel and dispense the liquid by gently pressing the pipette knob to the first stop (#3). Withdraw the tip from the liquid. Some liquid will remain inside the tip. The liquid remaining in the tip can be dispensed back into the original solution (#4) or thrown away. Release the pipette thumb to the ready ...
