Variety of Pre-pulled Micropipettes Available

TipsEliminate the cost and trouble of making your own micropipettes — WPI can quickly supply your need for consistently sized pre-pulled glass micropipettes for injection of dyes or proteins into cells, oocytes and for many other biomedical laboratory applications. Tip diameters (ID) range from 0.1 to 10 micrometers. Micropipettes are available as plain shank or with luer fittings.

  • Schott Duran borosilicate glass
  • 0.5 micrometer and smaller ID micropipettes include an internal glass fiber for easy filling
  • Tip inner diameter tolerance ±20%
  • Short taper yields high strength
  • Nominal length ≈ 50 mm
  • OD:ID = 1.33:1
  • Standard capillary outer diameters are 1.0 mm (thin-wall) or 1.14 mm
  • Every pipette individually tested and inspected
  • Vacuum packed

Silanized Tips (Luer Shank)

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.
