TGem Ultra is a full-spectrum micro UV-Vis spectrophotometer covering a wide wavelength range from 185 to 910 nm, providing comprehensive analysis beyond routine nucleic acid and protein quantification.

In addition to microvolume measurement (0.5–2 μl), TGem Ultra integrates both pedestal and cuvette modes in a single system, enabling flexible workflows for a broad range of laboratory applications. It supports full spectral scanning as well as customized wavelength detection, making it ideal for advanced research and complex sample analysis.

With a wide detection range from 2 to 27,500 ng/μl (dsDNA), TGem Pro enables direct measurement of high-concentration samples such as nucleic acid extraction products and PCR outputs without the need for dilution, significantly improving workflow efficiency.

The system supports a wide range of applications including dsDNA, ssDNA, RNA, oligo DNA and oligo RNA quantification, making it suitable for diverse molecular biology experiments.

For extremely low concentration samples, fluorescence-based quantification using TGem One Fluorometer is recommended for higher sensitivity.

The flagship cuvette version (OSE-260-06-AM) is equipped with a dedicated cuvette module designed for enzyme kinetic analysis and low-concentration sample measurement. With built-in temperature control (up to 37°C) and adjustable magnetic stirring (10–900 rpm), the system ensures optimal reaction conditions and improved data reproducibility for dynamic assays.

Compared to NanoDrop, which mainly focuses on rapid nucleic acid quantification, TGem Ultra offers both microvolume convenience and full UV-Vis analytical capabilities in one platform. It is an ideal solution for laboratories requiring higher flexibility, expanded applications and more advanced analytical performance.
