Shimadzu Prominence SIL-20AC Thermostatted Autosampler

The SIL-20AC is equipped with a sample cooler with a built-in dehumidifier to minimize condensation problems. Samples can be maintained at a fixed temperature from 4ºC to 40ºC. Temperature equilibration is rapid and uniform, so heat or cold sensitive sample constituents remain stable.

Features:

• Adsorption of sample constituents has been reduced to an absolute minimum. Enhancements include:
  • Special needle treatment (patent pending) – masks active sites and minimizes ionic interactions
  • One piece injection port/needle seal at valve center – eliminates sample transfer tubing
  • Redesigned needle seal to minimize surface area
  • Low-adsorption valve materials
  • These advancements combine to eliminate cross contamination – even with difficult basic and hydrophobic compounds. For especially difficult samples, dual-solvent rinsing is available.
• High Speed/Throughput – 10s for a 10 µL injection
  • Ultra-high-speed sample processing – 10 seconds for a 10 µL injection – is now possible with the SIL-20A/20AC. Used together with a high-speed separation column makes an analysis cycle time of less than one minute a reality.
• Precise Sample Injection
  • Greater injection volume accuracy has been attained by incorporating a high-performance precision metering pump. Injection volumes of less than 1 µL are possible, and the direct injection method means valuable samples are never wasted.
• Optional Rack Changer
  • Significantly Increases Sample Capacity
  • With increased speed, capacity becomes a limiting factor for unattended operation. The optional rack changer automatically loads microplates into the SIL-20A/AC sample compartment. The 12-plate capacity ensures convenient processing of over 1000 samples. The “C” model changer has the same plate capacity and incorporates a 4ºC to 40ºC cooling function, matching that of the SIL-20AC.
