Biochrom Libra S21 Vis Spectrophotometer

Introducing a meticulously maintained second-hand spectrophotometer, designed to meet the demanding needs of precision laboratory research. This system offers a versatile wavelength range of 325 – 1100 nm, equipped with a high level of wavelength accuracy at ±1 nm and reproducibility at ±0.5 nm. It utilizes a Xenon lamp (PTR) as its light source, operating through a split beam with reference beam compensation, ensuring reliable measurements.

The system operates with a bandwidth less than 3 nm, and is fitted with a dual solid state silicon photodiode detector, ensuring consistent photometric data. The photometric range spans from -3.000 to 3.000 A, with concentration units from -9999 to 9999, and transmittance from 0.1 to 200%T. It offers impressive photometric accuracy, with a precision of ±0.5% or ±0.003A up to 3A at 546 nm, and reproducibility at 0.5% of the absorbance value.

For spectral scanning, the system provides scanning capabilities up to 900 nm. It boasts low stray light, less than 0.05%T at both 220 nm and 340 nm, and zero stability of ±0.002A/h at 0A after warm-up, which underscores its superior performance.

With dimensions of 510 x 370 x 230 mm and a weight of 13 kg, this robust spectrophotometer is compact enough for convenient placement in any lab environment. This equipment promises reliability and precision for your research needs.
