|Buck Scientific tests each hollow cathode lamp at our Norwalk, CT manufacturing facility on the new Atomic Absorption spectrophotometers before shipping them out to customers. All lamps have a 6 month warranty against manufacturer defect.* (With the exception of Selenium hollow cathode lamps, they have a 2 month warranty due to the volatility of Selenium)|
Cobalt Primary Line: 240.7 nm
Slit Setting: 2
Buck Scientific sources hollow cathode lamps from a few different vendors, since over time we have learned that some manufactures do different elements better than others.
Take our word for it, we have used them all over the last 40 years!
- Long life for economical, operator convenience
- High intensity light output resulting in low signal-to-noise ratio and excellent performance
- Low operating current to extend lifetime of lamps even further
- Enhanced sensitivity to produce great results even with difficult samples
- Wide selection so Varsal can be your one source for all HCL's
- Reliable quality so your expectations will always be met
Our lamps are specially designed to emit high intensity at the recommended operating current, resulting in low Signal-to-Noise ratio and excellent performance.
Low Operating Current
Our lamps may be operated at only half of the instrument manufacturer's recommended current for sufficient intensity, resulting in long lifetime of the lamps.
|Glowing starting voltage:||300 V|
|Radiation stability:||1% over 30 minutes|
|Size: 2" for Perkin-Elmer||Diameter: 50 mm, Length: 180 mm|
|Size: 1.5" lamps||Diameter: 38 mm, Length: 160 mm|
Utilizes Total Quality Control (TQC) to monitor, control and inspect every single step of the hollow cathode lamp manufacturing process. The materials are carefully selected in our manufacturing to avoid spectral interference from fill gas or impurities in the cathode material.
1.5" Hollow Cathode Lamp
- Uncoded 1.5" lamps for all systems except Perkin-Elmer system.
- Self-reversal 1.5" lamps for Shimadzu, Thermal Jarrel Ash, LEEMAN Labs whose AAS system requires self-reversal background correction abilities.
- Even though Varian systems do not require self-reversal lamps, they are suggested and recommended because of longer life time and higher intensity.
