Beckman Coulter™ Capillary Cartridge Coolant

The P/ACE MDQ instrument separates sample components within a fused-silica capillary, using one of several modes of electrophoresis. All of these modes are generally referred to as Capillary Electrophoresis (CE).

• The capillary cartridge protects the capillary, provides a path for liquid coolant, simplifies installation, and aligns the detection window
• The capillary temperature is controlled with an inert liquid that circulates through the cartridge
• Temperature is controlled in a range from 10°C below ambient (minimum 15°C) to 60°C
• Coolant flows through the cartridge via two openings in the bottom of the housing (located between the ends of the capillary)
• Coolant characteristics:
  • Clear, colorless liquid with hydrocarbon odor
  • Boiling point: 97°C
  • Specific gravity: 1.8 at 20°C
  • Insoluble in water
  • Vapor density: 14; Vapor pressure: 42mm Hg at 20°C
