Multichannel Pipette Literature Review

Hans Jirgen Bigus Uhl, “MULTI-CHANNEL PIPETTE DEVICE” Patent Application Publication

  • each pipette channel has at least one associated, separate micro membrane pump for dosed Suction and/or discharge of fluids
  • informative for the basic structure
  • tells us about the internal working

Kenneth Rainin, Walter S. Watson "LIQUID-END ASSEMBLY FOR MULTICHANNEL AIR-DISPLACEMENT PIPETTE" United States Patent

  • Give a detailed insight into the working of a multichannel pipette containing a single cylinder for each individual channel.
  • Discusses the advantages of being able to replace a single cylinder at a time, depending on the requirement.
  • Elaborates on the mechanism used to eject spent tips without touching them.

Kenneth O'Connell and Nicholas Vitale "LIQUID END ASSEMBLY FOR A HANDHELD MULTICHANNEL PIPETTE WITH ADJUSTABLE NOZZLE SPACING" United States Patent

  • Design for 8 nozzle pipette with the varying distance between adjacent tips is achieved using the inline alignment technique which is controlled by using the knob like fasteners
  • working mechanism is explained here with the minute part details

Martin Klingenberg, “When a common problem meets an ingenious mind” The invention of the modern micropipette"EMBO Reports"

  • invention of the piston-driven, plastic-tip micropipette
  • breakthrough in the invention of the micropipette
  • introduction of coaxial springs

EPPENDORF "Single nozzle pipette user manual"

  • How Does Pipette work is explained and the principle on which it is based is explained
  • How to use the pipette properly and overcome the general mistakes made while using pipette are explained
  • Maintaince of the pipette is also explained

"Multichannel pipettes - the easy way to increase productivity" article by Carole Staniford, Anachem Bioscience.

  • This article talks about the increasing demand of Multichannel pipettes with the advent of microtiter plates. Due to the arrangement of wells in a microtiter plates, the multichannel pipette also has some of the other combination of 4-12 channels to facilitate ease of use.
  • It elaborates on Repetitive Strain Injuries (RSI) that can be caused due to the use of single-channel pipettes to conduct large scale laboratory tests.
  • The author further talks about different ISO standardization for Piston Operated Volumetric Apparatus (pipettes). She also explains the process and the number of tests needed for the validation and standardization of a multichannel pipette.

"Open source 3D-printed 1000 microlitre micropump" by Jorge Bravo-Martinez

  • rack-pinion mechanism used in the pipette is explained
  • Cost estimation is done Using BOM and the material used
  • pipette validation is bt taking some sample value

"Open Design 3D-Printable Adjustable Micropipette that Meets the ISO Standard for Accuracy" by the department of bioengineering, University of Illinois, Chicago

  • assembly process of the 3D printed parts are explained
  • sample validation is explained using formula-based and sampling technique which helps in error adjustment
