Double Beam Spectrophotometer

Brands: Scitek

~~$0.00~~

Shipped From Abroad

A Double Beam Visible Spectrophotometer measures the intensity of light absorbed by a sample using two separate beams of light. One beam passes through the sample, while the other serves as a reference. This setup helps to compensate for any fluctuations in the light source, providing more accurate and stable measurements. It’s commonly used in research and analytical laboratories for precise chemical analysis.

Delivery & Availability:
Typically 10-21 working days – excluding furniture and heavy/bulky equipment. Please contact us for further information.
