Pasteur Pipettes for NMR Tubes

Our new pipettes display a uniformly drawn tip that can easily access the bottom of our 8" (203mm) long 5mm NMR tubes.

Manufactured from borosilicate glass that meets the requirements of both the USP (United States Pharmacopeia) Type I specification and the Type I Class B specification for the ASTM E438 standard (formerly known as the American Society for Testing and Materials, now ASTM International). Glass meeting these specifications possesses superior chemical resistance, and is the least reactive glass available, exhibiting a very low level of extractable material which can otherwise contaminate very sensitive or highly purified samples. This type of glass also withstands thermal shock very well because of its comparatively low coefficient of thermal expansion.

In addition to being ideally suited for use in all 5mm NMR tubes, including our medium wall NMR tubes with walls up to 0.8mm, our pipettes also accommodate our 3mm NMR tubes of 7" (178mm) length with walls up to 0.38mm in our Select Series and Sample Vault Series.

Our pipettes can contain a total volume of 2.5ml. Because NMR tubes of 5mm diameter and less generally require no more than 1ml sample volume, our pipettes provide ample volume while allowing a margin of safety resulting from the large remaining headspace.

The uppermost part, or body, of our pipette measures 7mm in outer diameter, permitting use with most rubber bulbs and other pipetting devices commonly stocked in a typical laboratory.
