LS 6500 Scintillation Counters combine advanced scintillation technology, configurability to meet your exact requirements and built-in upgradability to add features as you need them. Beckman Coulter offers unparalleled flexibility in a single high performance system, without the need of a dedicated external computer, and a partnership with you that begins with system installation and continues throughout the lifetime of your instrument.

The Basic System

The LS 6500 Liquid Scintillation Counting systems provide:

• Advanced Technology

State-of-the-art instrument that eliminates early obsolescence by integrating the counting system, computer power and data management.

• Configurability
  Enhancement packs and single options let you tailor the system to meet your specific requirements.
• Upgradeability
  Add features and future enhancement packs throughout the lifetime of the system if your applications change.

State-of-the-Art Design
Advanced electronic components, such as a Motorola 68000 Series microprocessor supported by a digital signal processor, maximize technological lifetime and make the LS 6500 fast and efficient.

High Spectral Resolution
A 32,768 channel multichannel analyzer gives you an eight-fold improvement in effective resolution (0.06 keV per channel) over that of conventional liquid scintillation counters (0.5 keV per channel). This provides the basis for:

• DPM results without quench curves
• A more precise quench monitor
• Superior results for multi-label studies
• Automatic color detection and correction

Accurate Results...
Our patented H-Number Plus is standard in LS 6500 Value Systems and represents a significant improvement in accuracy and reproducibility. Quench is determined to a tenth of a channel.

...and Simple Operation
The LS 6500 guides you with ease-to-follow menus and context-sensitive help screens. Operate the system without an external computer. Store and transfer data securely with the optional Data Buffer & Transfer System.

Space Requirements

A minimum bench or table space of 132 cm (52 in.) wide and 71 cm (28 in.) deep is required for the LS 6500 instrument. The surface must be level and flat and capable of supporting 275 kg (600 lbs.) without bowing of flexing. To allow for optimal air circulation and ease of service, a recommended space of 152 cm (60 in.) wide and 81 cm (32 in.) deep should be dedicated to the instruments.
