  • pipett, mis võimaldab vedeliku kogust mõõta kolvi juhitava nihkumise põhjal
  • type of pipette that operates viapiston-driven displacement
kolvinihkepipett
Usage examples
  • Erinevalt õhknihkepipetist, mis väljastab vedelikku pipeti otsas oleva õhkpadja abil, puutub kolvinihkepipetis olev kolb prooviga otseselt kokku, võimaldades aspiratsioonijõul konstantseks jääda.
positive displacement pipette
Usage examples
  • 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.

  • laboratoorne mõõtevahend, mida tavaliselt kasutatakse keemias, bioloogias ja meditsiinis mõõtmisega paika pandud vedelikukoguse transportimiseks
  • laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser
pipett preferred
Usage examples
  • Pipette, alates ühes tükis klaaspipettidest kuni keerukamate reguleeritavate või elektrooniliste pipettideni kasutatakse vedelike sisse tõmbamiseks ja väljastamiseks, kusjuures ühekanalipipettidel on üks kolb-silinderpaar ja mitmekanalipipettidel on igal kanalil kolb-silinderpaar ning samal ajal saab väljastada sama koguse vedelikku mitmesse anumasse, nt mikroplaadi süvendisse.

pipette preferred
Usage examples
  • Pipettes come in several designs for various purposes with differing levels of accuracy and precision, from single piece glass pipettes to more complex adjustable or electronic pipettes, and many pipette types work by creating a partial vacuum above the liquid-holding chamber and selectively releasing this vacuum to draw up and dispense liquid.

mahtpipett preferred
kolbpipett
volumetric pipette preferred
bulb pipette
belly pipette
  • pipett, mis võimaldab lahuse mahu äärmiselt täpset mõõtmist
  • pipette allows extremely accurate measurement (to four significant figures) of the volume of a solution
mahtpipett preferred
Usage examples
  • Mahtpipetid omavad suurt pirnikujulist osa, mille ülalpool on pikk kitsas osa ja millel on üks gradueerimismärk, mis on kalibreeritud ühe ruumala väärtuse jaoks vastavalt (1, 2, 5, 10, 20, 25, 50 või 100) ml.
kolbpipett
mõhkpipett
volumetric pipette preferred
Usage examples
  • Volumetric pipettes have a large bulb with a long narrow portion above with a single graduation mark as it is calibrated for a single volume (like a volumetric flask). Typical volumes are 1, 2, 5, 10, 20, 25, 50 and 100 mL.
