Description. Manufacturer: Perkin Elmer. Model: Lambda 40. The device is a dual-beam photometer equipped with a deuterium and halogen lamp. It offers a wavelength range of 190 to 1100 nm and a spectral bandwidth that varies between 0.5 nm, 1 nm, 2 nm and 4 nm. The universal cuvette holder is suitable for cuvettes up to 100 mm long. The device also has a display and a keyboard and can also be used as a stand-alone device. The year of manufacture is 2000 and the dimensions are approximately 65 x 26 x 56 cm (width x height x depth) with a weight of approximately 26 kg. It operates with a power supply of 100-240 V and a frequency of 50/60 Hz. The functionality of the photometer has been tested, including absorption tests with certified filters and tests of wavelength accuracy based on the holmium spectrum with a certified filter. A control PC with Windows 7 is included. ---. Description. Manufacturer: Perkin Elmer. Model: Lambda 40. This is a dual beam photometer with a deuterium and halogen lamp.
