Autosamplers

SIL-20A / 20AHT
Supporting High-Throughput Analysis
The SIL-20A is a total-volume injection-type Autosampler that enables high-speed
injection and multi-sample processing. It was designed to ensure greater stability,
with improved durability attained through modifications in valves and sample loops.

SIL-20AC / 20ACHT
Equipped with Cooling Function
The SIL-20AC is equipped with a sample cooler that incorporates a
dehumidifying function. Samples can be maintained at a fixed temperature in the
range of 4°C to 40°C. The high cooling speed makes it possible to keep easily
decomposed sample constituents in a stable condition.
Rack Changer II
Supporting Multi-sample Processing
Maximum 12 microplates can be set. The robot arm in the rack changer
automatically loads both micro-plates and racks for standard 1.5 mL vials into the
autosamplers. It is a powerful tool for the analysis of a large number of samples.

for the sampling needle (patent pending) and rethinking the
structure of the needle seal and the materials used in flow-line
parts. As a result, there is hardly any sample carryover. Also,
the adoption of a PEEK rotor seal allows use over a wide pH Not detected
range, from strongly acidic conditions to strongly basic
conditions. Using the optional rinse kit (228-43042-91)
makes it possible to rinse the sampling needle with two
different solvents, selected in accordance with the purpose. Cross-contamination Test for Chlorhexidine

High Throughput

Only 10 seconds* are required for sample injection.
High-speed vertical motion of the needle enables
ultra-high-speed sample processing, which was considered
impossible with conventional autosamplers. Using in
combination with a high-speed separation column makes an
analysis cycle of less than one minute a reality.
