About this item
U-3900 and U-3900H spectrophotometers are comprehensive, research-grade solutions. They provide excellent performance afforded by low stray light, selectable band pass and high energy.
- Double-beam stability provides improved accuracy and repeatability over extended periods of time
- Ability to reference-beam attenuate highly absorbing species for improved signal to noise
- Selectable scanning rate range of 1,5 to 2400 nm/min and changeable scan rate for the UV region to minimise noise further
- Interface via USB and a laptop or notebook PC format, can easily sit on a flat surface of the instrument (see picture)
The U-3900H is useful for measuring of samples with high absorbance/low transmittance yet still achieving excellent linearity.
Ordering information: Including sipper systems, alternative cell holders, filter holders and integrating spheres. Please contact your local Avantor specialists.
Delivery: UV Solutions for U-3900 software (supplied) offers the flexibility and wide ranging functionality.
