Nexera Series
SIL-30AC
SIL-30AC Autosampler
The total-volume injection SIL-30AC autosampler features a pressure tolerance of 130 MPa as well as the world’s fastest sample injection (10 seconds), which dramatically reduces the total cycle time. It includes auto pretreatment and overlapping functions as standard, and an optional loop-injection method configuration to minimize delay volume. With reduction of the needle contact area, special coatings, surface treatments, and a new needle seal, the SIL-30AC reaches a new level of low carryover performance, which is especially beneficial for LCMSMS analysis. In addition, the included sample cooler features a dehumidifier function for storing samples at a constant temperature between 4°C and 40°C.
Rackchanger II and SIL-30AC Autosampler
The rackchanger unit replaces the microplates on autosampler racks to enable samples to be continuously analyzed . It allows loading up to 12 microplates inside the unit (maximum 4608 samples). Samples can be temperature-controlled with a block heating/cooling system (with dehumidifier function and 4 °C to 40 °C range) not only to refrigerated temperatures, but also to stable temperature levels near room temperature.

Prominence Series
SIL-20A/20AC Autosampler
SIL-20A
The SIL-20A is a total volume injection type (direct injection) autosampler that enables high-speed injection and multi-analyte processing. Materials used in needle, valve, and other flow lines were closely considered and a needle rinsing function is provided to carefully minimize cross-contamination (carryover), which is especially useful for high-precision LC-MSMS analysis. The SIL-20AC includes a sample cooler that features a dehumidifier function for storing samples at a constant temperature between 4 °C and 40 °C.
Rack Changer
The rackchanger unit exchanges the microplates on autosampler racks to enable samples to be continuously analyzed. 12 plates can be mounted inside the main unit and stored under refrigerated conditions.
