Boiling flasks and general laboratory glassware

DURAN® NMR tubes

three accuracy classes

NMR tubes are available, according to requirement, in three accuracy classes. The correct tube can be selected depending on magnetic field and spin. The tubes are noteworthy for their close tolerances and accuracy, especially to their straightness, wall thickness and wall thickness distribution. Consequently, quick and accurate test results are achievable.

 

Type Economic:
The disposable for economical use in fully automatic sample dispensers or where high throughputs are involved.

 

Type Professional:

For professional use in industry and research in the medium and high resolution area of NMR spectroscopy.

 

Type Scientific:
For scientific use with high value samples and optimum substance exploitation in the highest resolution range of NMR spectroscopy.

DURAN® centrifuge tube

with round bottom

Centrifuge tubes are thick-walled and very resistant to mechanical loading. The higher density fraction collects in the bottom. Consequently solids can be collected and separated.
