Pipette

Overview

Calibrated micropipettes eliminate the cost and trouble of making your own micropipettes

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

 

Applications: 

• CCIT (Closed Container Integrity Testing)
• Injection of dyes or proteins into cells, oocytes or other biomedical laboratory applications 
• Package Integrity Testing
• Sterile Barrier Testing 
   

Certificate of Compliance

A Certificate of Compliance is available for these MicroTips. Please request one when placing your order.
