Hollow Cathode Lamps
OVERVIEW
Varsal designs and manufactures a complete line of hollow cathode lamps to meet the strictest standards of most atomic absorption spectrometer instruments. We manufacture lamps of different sizes and with argon and/or neon gas fills to assure optimum results on a wide variety of instruments. Our technical ability to produce hollow cathode lamps that meet the demanding specifications of instrument manufacturers is only surpassed by the company's customer service and on-time delivery responsiveness.
Varsal Advantages
- 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
High Intensity
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.
| Category | Data |
| 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 |
Quality Control
Varsal 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.
Every lamp is thoroughly tested prior to shipment. Under same testing conditions, the radiation intensity of every lamp is equal to or better than those made by other vendors.
Warranty
All hollow cathode lamps are warranted for a standard 2-year limited warranty. Each regular element lamp carries a 5000 mA-Hour warranty (such as Cu, Ni, Ca, MG, etc). Each volatile element lamp carries a 3000 mA-Hour warranty (such as As, Se, Sb, Bi, Pb, Cd, etc). Varsal will replace any lamp that does not perform to its specification during this period assuming the lamp was properly used.

List of Atomic Absorption Spectrometers Manufacturers
Varsals HCL can be used on Atomic Absorption Spectrometers manufactured by:
- Perkin-Elmer
- Varian
- BUCK Scientific
- GBC
- Hitachi
- Shimadzu
- Thermal Jarrel Ash
- IL
- Unicom
- LEEMAN Labs
- Phillips
1.5" Hollow Cathode Lamp
- Regular 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.
2" Hollow Cathode Lamp
- Uncoded (regular) 2" lamps can be used for all Perkin-Elmer atomic absorption spectrometers. Some models do require different conversion cables.
- Some models use a 9 - pin connector while the AAnalyst Series use a 4-pin connector as pictured below. Please select the right lamp as pictured below for your instrument.

Disposal of Lamps
When disposing a used lamp, be sure to comply with all state, province and country regulations to ensure the disposal is legal and environmentally proper.
Hollow Cathode Lamp Activator
Do you...
- Keep your HCL's on the shelf for a long time?
- Need to warm up your HCL's?
- Want to extend your HCL's lifetime?
If you answered ¡°YES¡± to any of the above, you need a JH-B HCL Activator in your lab.
The JH-B HCL Activator is a power supply specially designed to activate HCL¡¯s. In general, the emission intensity and stability of an HCL can diminish after prolonged storage (longer than 3 months), or after prolonged operation. After treatments with the JH-B HCL Activator, the durability of the lamp and the stability of the emission signal can improve dramatically.
Our HCL activator can be used as a pre-warming device for atomic absorption and atomic fluorescence systems, thereby shortening the pre-warming time required for routine multi-element testing. The activator can be used as a power supply for other stable light sources as well.
The HCL activator utilizes continuously adjustable constant-current circuits. HCL anodes consist of materials that can collectively absorb undesirable gaseous species internally during HCL excitation/emission. By setting the activator in ¡®Reverse (R)¡± position, the anode can be heated to absorb these gases, increasing the vacuum inside the lamp. This is critical for optimum lamp performance. Signal intensity and stability can also be maximized by activating the surface of the HCL¡¯s cathode. This can be done by adjusting the activator to ¡°Forward (F)¡± position.
