SC-Micro Autosampler

The SC-µDX autosampler, although designed for micro volume samples (25-1000 µL) maintains the flexibility of all SC-DX autosamplers and is capable of sampling up to 125 mL bottles. The durable long-life carriage and multiple probe options ensure accuracy when sampling micro volume vials or microplates. Link this to main page of SC micro main page.


  • Smallest foot print and capacity of any autosampler
  • Reset probe
  • Dual flowing rinse stations
  • Micro vials to 125 mL bottles simultaneously configured

Autosampler Enclosures

ICP and ICPMS sample integrity is maintained with the ESI SC-DX autosampler enclosures. The enclosures can be configured either as a dust cover or ULPA-filtered minienvironment.


  • Protects samples from airborne contamination
  • Exhaust acid fumes to protect the laboratory environment
  • Clear acrylic construction for easy sample viewing
  • Covers only the sample area—the electronics are kept outside the enclosure
  • Large hinged door provides easy access to sample racks at any time
  • Exhaust port (50 mm, included) connects to laboratory ventilation system
  • The ULPA (Ultra-Low Particle Arrester) filter upgrade is 99.999% efficient down to 0.12 microns

ULPA - Ultra-Low Particulate Arrester Air Filter and Mounting Plate

The ULPA (Ultra-Low Particle Arrester) filter creates a clean, positive pressure environment for samples and standards and prevents airborne contamination. The ULPA filter removes 99.999% of 0.12 micron particles.

The ULPA filter mounting plate fits the SC-2 DX, SC-4 DX, SC-µDX and microFAST MC on either the right or left side of the enclosure.

microFAST MC

The microFAST MC combines the capabilities of the SC-µDX autosampler with single or dual loop FAST capabilities and syringe based sample loading/injection. The system accurately loads a loop and then smoothly injects the solution into a μFlow concentric nebulizer at defined rates from 5-1000 μL/min. The valve on the flow injection system selects from two discrete, parallel flow paths. This allows rapid switching between solutions with minimal dead volume between the valve and the nebulizer.


  • Total sample consumption
  • Eliminate waste
  • Micro volume samples (5-1000 μL)
  • Micro flow rates (5-1000 μL/min)
  • Inject complete sample
  • Dual loop system
  • High sample throughput
