The SpectroQuest™ 2800 is the most economic general-purpose UV/VIS spectrophotometer on the market. It is a stand-alone model with 4 nm fixed bandwidth and provides excellent performance for measurements in the range of 190 nm to 1100 nm. It has a large angled LCD screen with contrast adjustment for comfortable viewing in a variety of room conditions. The large sample compartment (100 mm) accommodates a wide range of cell holders and accessories including peristaltic sipper and peltier system. Optional PC download software and PC Windows® application software make this instrument very versatile. Easy one-button recall and non-volatile memory storage make this spectrophotometer the choice of many classrooms and laboratories. The pre-aligned deuterium lamp allows for easy lamp replacement. Lamp usage and the status of the lamps are also available to the user. This model comes with USB and RS-232 ports for communication and software upgrades.
