T8DS Double Beam UV-Vis-Analytical Instruments-TN Lab Supply

T8DS Double Beam UV-Vis

  • $5,999.00 USD

T8DS is a high-performance double beam scanning spectrophotometer with a variable spectral bandwidth. 

The Czerny-Turner Monochromator with a holographic grating keeps the stray light at a minimum and offers an excellent optical resolution.

 The use of a photomultiplier tube as detector delivers exceptional sensitivity.

 The true double-beam optical system coupled with an efficient and well-proven electronic control system ensures high stability and low background noise.
