SQ2800 Single Beam UV-Visible Scanning Spectrophotometer

The SQ2802 Series is an advanced single beam design consisting of three models: Stand-alone model SQ-2802 with 1.8nm fixed bandpass and Model SQ-2802 with variable slits (1nm, 1.8nm and 4nm); PC model SQ-2802PC with 1.8nm fixed bandpass and can be controlled either by the keypad, or remote controlled from a computer with the included software package.

SQ-2802 has all the features that SpectroQuest line offers in a stand-alone unit. The PC models come standard with Windows based applications software (PC not included) and can perform basic Abs./%T/Conc tests without a PC. All instruments provide excellent performance and flexibility for your applications. The large sample compartment (100 mm) accommodates a wide range of all cell holders and accessories including perisgaltic sipper and peltier system.
