The best manufacturers of double beam spectrophotometers

When comparing the technical specifications and characteristics, the most suitable equipment for the laboratory is the KALSTEIN spectrometer. Although its price may be higher compared to the Shimadzu UV-1900i and Thermo Fisher Genesys, KALSTEIN provides a greater performance and durability guarantee, making it the most cost-effective option in the long run.

Regarding baseline stability, Kalstein shows efficiency with โ‰ค0.0004A/h. Additionally, this manufacturer offers a wide range of useful accessories, from PC software to a test tube holder, exceeding in variety to Shimadzu and Thermo Fisher. This makes it an excellent purchase option for any laboratory seeking flexibility and precision at the best price.

KALSTEIN Spectrometer YR01862/YR01862-1/YR01862-2

The KALSTEIN Spectrometer offers accuracy and reliability with its different models YR01862/YR01862-1/YR01862-2. As a manufacturer, KALSTEIN guarantees exceptional performance and a long useful life. Regardless of the price, the purchase of this equipment is a long-term investment. The main benefit is its high sensitivity and accuracy, while the possible disadvantage would be the initial cost of the purchase. https://kalstein.pl/product/spectrophotometer-double-beam-yr01862-1-yr01862-2/

The Kalstein equipment stands out in terms of spectral precision, with a wavelength accuracy of ยฑ 0.1 nm at the D2 peak 656.1 nm and ยฑ 0.3 nm for the entire range. It also stands out in its low stray light, showing lower values than its competitors. This factor is decisive when considering the purchase or sale of these devices.

Shimadzu UV-1900i vs Thermo Fisher Genesys

The Shimadzu UV-1900i is a popular choice for labs. It offers fast and accurate results at a more affordable price than other models. However, as a manufacturer, Shimadzu cannot match the durability and reliability guarantee offered by KALSTEIN. Therefore, the main advantage is its affordability, while its disadvantage is the doubt about its long-term durability.

Thermo Fisher Genesys is a recognized name in the field of spectrometers. It offers the advantage of good performance for general analysis, although the disadvantage is the high cost of acquisition and maintenance. Comparatively, the purchase and sale price can be a deterrent for some labs.

Optical system and wavelength range

The KALSTEIN YR01862 model and its equivalents offer a double-beam optical system, as do the Shimadzu UV-1900i and Thermo Fisher Genesys models. These three devices share a wavelength range of 190 to 1100 nm, translating into high adaptability to various lab applications.

Kalstein stands out for its double-deuterium and tungsten lamp light, similar to Shimadzuโ€™s. However, Thermo Fisher Genesys differs by using a xenon lamp. In terms of the interface, Kalstein leads with its 10-inch color touchscreen, superior to the competitorsโ€™ 8 and 7-inch ones.
