The ultra-micro nucleic acid and protein analyzer measures the A260 and A280 values of nucleic acids and proteins to determine sample concentration. This instrument is specifically designed for nucleic acid and protein quantification and is widely used in clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety inspection, molecular biology research, and other fields.
Ultra-micro sample loading platform: Requires extremely low sample volumes, with detection achievable using just 0.3 to 2.5 μl.
High-precision motor controls optical path length, enabling automatic switching between 1 mm, 0.2 mm, and 0.05 mm settings. This accommodates both high- and low-concentration samples without requiring additional dilution or concentration, achieving an upper detection limit up to 200 times higher than conventional UV-Vis spectrophotometers.
Utilizes a stable LED light source with a long lifespan and consistent performance, eliminating the need for warm-up time and enabling immediate testing upon startup.
Employs a UV silicon photodiode sensor with outstanding stability in the ultraviolet spectrum, delivering accurate results for nucleic acid and protein detection, along with excellent gradient dilution test fitting.
Open parameter editing: Allows manual input of extinction coefficients for nucleic acids and proteins, supporting custom detection protocols.
Supports OD600 detection for measuring cell, bacterial culture, and yeast growth density, offering comprehensive functionality in a single device.
All-in-one design: Utilizes a deeply customized Android system to independently complete sample detection and analysis. Simple operation requires no additional computer configuration and occupies minimal space.
Flexible Data Export: Stores approximately 100,000 test records, exportable via USB interface in Excel or TXT formats.
