Definition of pipette in English:



  • A slender tube attached to or incorporating a bulb, for transferring or measuring out small quantities of liquid, especially in a laboratory.

    • ‘Use a pipette to make two or three long lines of water down the desk.’
    • ‘Next, they took an unfertilized egg from a second sheep and removed its DNA, carefully sucking it out with a thin glass tube called a pipette.’

    • ‘A constricted glass pipette was used to mechanically separate cells from each other.’
    • ‘Preparation of patch pipettes and electrophysiological instruments were the same as described above.’
    • ‘Patch pipettes were filled with the same 100 MM KCl solution.’
    • ‘I showed the candidates how to use a pipette - a hand-held tool for manipulating small volumes of liquid - and invited them to have a go.’
    • ‘The caudal medulla was exposed to insert a microinjection pipette into the XII nucleus.’
    • ‘The inner diameter was measured by inserting a probe pipette with a known diameter profile (characterized by scanning electron microscopy).’
    • ‘The kit contains test tubes, pipettes, funnels and other lab materials necessary for multiple experiments and activities.’
    • ‘This material was transferred to 1.5 ml Ependorff tubes with pipettes.’
    • ‘The pipette was attached to the test tank 2 cm above the water surface, creating a perturbation on the surface when water was dripped into the aquarium.’
    • ‘The organic phase was transferred with a disposable pipette, and the aqueous phase was extracted twice more with the same solvents.’
    • ‘DNA was dialysed by inserting the DNA sample with a pipette into dialysis tubing and securing the ends with clips.’
    • ‘Application of pressure through the recording pipette accelerated the positive shift and removal of pressure simply slowed the shift.’
    • ‘Most techniques for monitoring whole-cell membrane capacitance work by applying a voltage stimulus via a patch pipette and measuring the resulting currents.’
    • ‘The pipette tip was placed 5-10 m above the dish surface.’


  • Pour, convey, or draw off using a pipette.

    ‘pipette the cells on to the coverslips’
    • ‘The cell suspension was pipetted onto cold glass slides; specimens were air-dried and stained with Giemsa (Sigma).’
    • ‘They were then dispersed into single cells by pipetting with Pasteur pipettes.’
    • ‘The top aqueous phase was pipetted into a fresh tube, and RNA was precipitated with 0.5 ml isopropanol.’
    • ‘After incubation, 5 ml of RPMI media were added to the cell flasks and then the cell solution was pipetted to a 50-ml vial.’
    • ‘Next, each 10 L of ant extract was pipetted onto a filter-paper disk.’
    • ‘A stock solution of 10-4 M pIX in methanol was pipetted into small containers and allowed to evaporate.’
    • ‘The cDNA samples were pipetted into separate tubes and stored at - 80°C.’
    • ‘Before each aliquot was pipetted, the cell suspension was swirled to ensure that the cells remained evenly dispersed.’
    • ‘The slide and a 20-x 40-mm coverslip were prewarmed to 37° and an aliquot of the agar suspension of cells was pipetted onto the prewarmed slide between the taped regions.’
    • ‘Aliquots of 5 l of sperm suspension were pipetted onto clean, dry glass slides.’
    • ‘After 24 h the contents of the container were stirred and 25 ml was pipetted into test tubes and freeze-dried.’
    • ‘These were shaken for 1 hour, then the solutions were centrifuged and the clear supernatant was pipetted into vials.’
    • ‘Single cell preparations were made by vigorously pipetting the cell suspension with a Pasteur pipette and by vortexing.’
    • ‘Subsequently 50 L of 50°C warm vesicle solution was pipetted into the cell.’
    • ‘The mixture was gently pipetted and then centrifuged at 1000 rpm for 10 minutes.’
    • ‘The chambers were assembled and collagen/cell suspension was pipetted inside the polycarbonate sheath.’
    • ‘Following this spin, the ethanol was pipetted off, and each DNA pellet was washed with 70% ethanol and dried in a vacuum centrifuge.’
    • ‘Aliquots of each blood sample were pipetted into 2 separate Teflon [R] digestion tubes.’
    • ‘Cells were ruptured by pipetting the resuspension 30 times through a Gilson 200 l tip.’
    • ‘Ten minutes after adding malate, we again pipetted the supernatant from the same dish into other test tubes.’


Mid 19th century: from French, literally little pipe, diminutive of pipe.
