Improved stability with solid-state light engines

Whether you are using an optical detector to analyze protein concentrations or sequencing RNA for drug discovery, repeatable processes are of high importance in life sciences research. Solid-state light engines are inherently stable and repeatable for years of service. Traditional arc lamps are inherently unstable, require repeated calibration and bulb replacement, and are poorly suited to any process that requires consistent light day after day, month after month, year after year.
