WPI can quickly supply your need for consistently sized, pre-pulled, glass, calibrated micropipettes. Tip Ø (int.Ø) 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 glass pipettes and get inside so easily.These glass needles are fabricated from Schott Duran borosilicate glass.

• Schott Duran borosilicate glass pipettes

• 0.5 µm and smaller int.Ø micropipettes include internal glass fiber for easy filling
• Tip int.Ø tolerance ±20%
