• 0.5 micrometer ID micropipettes include an internal glass fibre for easy filling
• Tip inner diameter tolerance ±20%
• Short taper yields high strength
• Nominal length approx. 50 mm
• Standard capillary outer diameters are 1.0 mm (thin-wall) or 1.19 mm
• Every pipette individually tested and inspected!
• 10-pack Vacuum-sealed

WPI can quickly supply your need for reproducible 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.
Recently described for use in mass spectrometry-based helium leak rate detection in pharmaceutical container integrity studies. See Kirsch, L.E. PDA J. Pharmaceutical Sci. & Technol. Vol. 51 [5], pp. 187-191.
