Dual Display

A customized Liquid Crystal Display gives simultaneous readout of wavelength and %Transmittance, Absorbance or Concentration. Concentration can be found by calibration to a standard or by direct factor entry. 

Ease Of Use

The simple keypad layout and operating protocols are designed to enable reliable operation by unfamiliar users. Photometric calibration, including 0% Transmittance is performed by a single key press.

Comprehensive Specification

The Model 6305 Spectrophotometer boasts an impressive optical performance for a product of this type. Stray light is minimized by the automatic activation of internal filters, whilst the narrow 8nm bandwidth provides the high degree of selectivity essential for most analytical applications. A precision stepper motor gives excellent positional control of the optical grating ensuring wavelength selection is both accurate and highly repeatable.

Fully GLP Compliant

The Model 6305 Spectrophotometer is supported by traceable calibration standards to provide the on-going assurance of accuracy required by Good Laboratory Practice (GLP). A wavelength calibration routine is performed at switch on and a 0%T setting is performed automatically during all calibration routines. 

Versatile Sampling System

A large cell chamber allows use with cuvettes from 10 to 100mm path length and test tubes from 10 to 25mm diameter. Changing the sampling configuration is quick and simple.

Full Interfacing Capability

There is full RS232 interfacing for connection, via industry standard connectors to printer or PC. Results can be downloaded by a single touch of the print key. The bi-directional interface also allows remote interrogation and control of the Model 6305 Spectrophotometer. An analog output is provided for connection to a chart recorder.

Additional Features of the Model 6305

The unique xenon lamp in the Techne^® model 6305 has the advantage of offering a broad spectral source and a guaranteed life of 3 years. NOTE: The Xenon lamp is warranted for 1 year. This enables the running costs for the 6305 to be minimized over the lifetime of the spectrophotometer since there is no deuterium and tungsten lamps to replace. The key feature of the xenon lamp is that 40% of the energy of the lamp is emitted below 400nm, with a maximum intensity of 260nm. This means an extra 5-10 times energy in the UV region compared to deuterium lamps and just where you need it for protein peptide or DNA study work.
