Evaluation of Technical Specifications: Comparison between Spectrophotometers of the Brands KALSTEIN YR01853 and PERSEE T6

The field of medical science and biological laboratories has greatly benefited from technological advancements. Among these indispensable tools, we find the Spectrophotometer, a device that uses light to measure chemical concentrations. In this regard, we present a detailed comparison of two outstanding brands on the market: KALSTEIN YR01853 and PERSEE T6.

Regarding Wavelength Range and Spectral Bandwidth; Both the KALSTEIN YR01853 model and the PERSEE T6 model have a wavelength range of 190-1100nm. This specification is crucial as it allows both spectrophotometers to work with a wide range of samples. Likewise, both models have a spectral bandwidth of 2nm, allowing for a detailed and accurate analysis of the samples.

Accuracy and Wavelength Repeatability

In terms of wavelength accuracy, we see a significant difference between both devices. The KALSTEIN YR01853 displays an accuracy of ยฑ0.5nm, while the PERSEE T6 model has an accuracy of ยฑ1nm. This means that the KALSTEIN model offers greater precision during measurement. https://www.kalstein.se/product/uv-vis-spectrophotometer-yr01853/

Regarding wavelength repeatability, both devices show excellent performance with repeatability โ‰ค0.2nm, ensuring the constancy and reliability of the results obtained.

Photometric Accuracy and Repeatability

Regarding photometric accuracy, the KALSTEIN YR01853 displays an accuracy of ยฑ0.2%T, while the PERSEE T6 has a slightly higher margin of error of ยฑ0.3%T. These figures indicate that the KALSTEIN model would have greater accuracy in measuring the concentrations of samples.

The photometric repeatability of the PERSEE T6 is slightly better, with โ‰ค0.15%T, compared to KALSTEINโ€™s, which is 0.2%T. This data shows that PERSEE ensures a lower margin of variation in repeated measurements.

Scattered Light and Stability

Both devices show scattered light equal to or less than 0.05%T, implying that they are capable of providing an accurate measurement by avoiding interference from other wavelengths. Regarding stability, the KALSTEIN YR01853 model stands out, guaranteeing stability of ยฑ0.002A/h@500nm, a parameter not specified for the PERSEE T6 model.

In conclusion, the KALSTEIN YR01853 and PERSEE T6 spectrophotometers show similar technical features. However, the KALSTEIN model stands out for its higher accuracy in both the wavelength and photometric measurements, while the PERSEE T6 demonstrates superiority in photometric repeatability. The choice between the two will depend on each laboratoryโ€™s exact needs for accuracy and repeatability.
