*10µm ID, 1.14mm capillary pipetters are for use in WPI's Nanoliter 2010.



  • Plain Shank or Luer Fittings


  • Injection of dyes or proteins into cells, oocytes or other biomedical laboratory applications

WPI can quickly supply your need for consistently sized pre-pulled glass micropipettes. Tip diameters (ID) range from 0.1 to 10 µm. Silanized Tips (Luer Shank) are available. Silanization waterproofs the glass to retard water when inserting into cell. This will not let the outside fluid run down the pipette and get inside so easily.These glass needles are fabricated from Schott Duran borosilicate glass.
