Heraeus 1-element 3BAXSR VC Hollow Cathode Lamp, Strontium Sr, 37mm Standard, low current 

Product name: 3BAXSR VC
Product no.: 80033006
Product group: Hollow Cathode Lamps
Brand: Heraeus Noblelight

Hollow cathode lamps (HCL) are discharge lamps designed for use in Atomic Absorption (AA) instruments. They consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. Noblelight offers the widest selection of single- and multielement coded / non-coded in low and high-current, 37 mm and 50 mm lamps in the industry.

Noblelight hollow cathode lamps are available both for OEMs and as a replacement lamp by discerning users the world over. The range includes standard lamps and data-coded versions for PerkinElmer and ThermoFisher atomic absorption spectrometers.

Single-Element Lamps

The Heraeus catalogue includes 70 single-element lamps in standard 37 mm (1.5 inch) and 50 mm (2 inch) diameters to fit almost any AA instrument. All cathode materials are selected from the highest purity available – usually 99.99 % or better – to ensure high spectral line intensity, stability and low noise with good analytical sensitivity. The window material is selected to achieve the optimum transmission of the primary spectral lines of the cathode element. Borosilicate glass is used for wavelengths over 350 nm, and high quality quartz for shorter wavelengths.

Standard 37 mm Lamps

37 mm hollow cathode lamps are suitable for most commercial atomic absorption instruments. Standard lamps may also be used in computer controlled spectrophotometers which are designed to take coded lamps as these instruments normally have the facility to be set up manually. Manual setting up of lamp current, wavelength, slit width, gas conditions and burner height takes only a few moments and allows the operator to set the optimum conditions for each particular analysis, which can be stored and recalled when required. Indeed in many cases the instrument will set default conditions for these parameters on entry of the element. Whilst these parameters are generally suitable for a particular element, they may need fine tuning to suit the specific analysis being carried out.
