UV Spectra Multi-Wavelength Analyzer
In bioprocessing, accuracy and repeatability are vitally important. The Kemtrak UV Spectra delivers high-performance, real-time absorbance measurement of proteins, peptides, polypeptides, monoclonal antibodies, RNA/DNA, and amino acids — an indispensable tool for biochemical production, quality control, and cleaning verification
Built for demanding biotech environments, the UV Spectra integrates smoothly into both R&D and GMP production settings, maintaining tight process control, maximizing yield, and ensuring consistent product quality. With user-selectable multi-wavelength detection spanning deep UV to visible wavelengths, it provides exceptional sensitivity, stability, and site-to-site consistency. Simultaneous measurement at multiple wavelengths achieves a massive dynamic range—from ultra-high protein concentrations exceeding 500 mg/mL down to trace levels below 0.001 mg/mL—without sample dilution or mechanical adjustment. This makes it equally effective across chromatographic fractionation, formulation, and CIP/SIP cleaning verification workflows.
- Deep UV: Wavelengths from 190 to 440 nm.
- Up to 10 simultaneous calibrations: Wavelengths are user-selectable.
- Broad dynamic range: From trace levels to high concentration without dilution.
- Digital connectivity: EtherNet/IP, PROFINET, Modbus TCP/IP.
- Environmentally responsible: Mercury-free, RoHS compliant.
- cGMP compliant: NIST-traceable in-situ verification.
- Light Source: At its core is a mercury-free deep UV xenon light source with a lifespan of up to two years of continuous operation.
- Interface: An intuitive touchscreen interface allows instant wavelength selection and verification using NIST-traceable standards without interrupting the process line.
