Spectrophotometers are essential instruments in any reputable laboratory. In this case, we will focus on the double-beam models from Kalstein and Mapada. Both pieces of equipment have impressive capabilities and functionalities, from an excellent wavelength range to high accuracy and repeatability.
The Superiority of KALSTEIN
Firstly, both brands offer a maximum and minimum wavelength of 190-1100 nm. However, there are some key differences in specifications that make Kalstein’s models stand out. Unlike Mapada UV-6100/UV-6100S models, Kalstein’s spectrophotometers have a variation of spectral bandwidth, allowing selected between 1.8nm/1nm/0.5, 1.0, 2.0, 4.0nm, offering greater flexibility in experiments.
Another area where KALSTEIN shows strength is the accuracy of wavelength. Whereas MAPADA has an accuracy of ±0.3nm, KALSTEIN’s models, YR 01863/YR01864/YR01865, show an impressive ±0.1nm at 656.1nm, and even in their worst scenario, they keep the same accuracy values as MAPADA at ±0.3nm. https://kalstein.eu/produit/double-beam-uv-vis-spectrophotometer-c-yr01863-yr01865/?lang=en
Relevance of Repeatability and Stability
When it comes to repeatability, KALSTEIN again leads the way with ≤0.1nm, ensuring consistent and reliable results. The stability of the equipment is vital for those looking for precise and repeatable results, and once again, KALSTEIN excels in this area.

Comparison of Performance and Applications
Both the KALSTEIN and MAPADA models have a high-resolution 320*240 LCD screen, and both use a silicon photodiode detector. However, the KALSTEIN model appears to offer significantly less scattered light, which is crucial in quantitative and qualitative measurements in a lab.
Ultimately, KALSTEIN’s instruments demonstrate their superiority in all the key specifications- spectral bandwidth, wavelength accuracy, repeatability, and less scattered light.
