HPLC-2025AS Autosampler


  • Precision
  • Precise injection volume

The autosampler adopts an integrated constant pressure needle and a precise syringe pump, which ensures accurate injection volume and excellent linearity, making the results more precise and accurate.

  • Low carryover to make results more accurate

The sampling needle is highly polished for the outer surface and passivated for the inner surface, which can effectively reduce the sample residue. The carryover is much lower when needle washing of the outer and inner surfaces are performed.

  • Reliability
  • Design of needle

With our integrated constant pressure sampling needle, the air pressure inside and outside the sample bottle can be balanced during sampling; the injection port is set on the sidewall to prevent bottle pad debris from clogging the needle during puncture.

  • Design of degassing unit of washing liquid

The built-in autosampler degassing unit can be used for degassing of washing liquid, avoiding interference caused by air bubbles.

  • Design of self-compensation injection pump

The maintenance-free self-lubricating guide device and self-compensating sliding screw are used for real-time compensation of the slight wear, and it has excellent motion accuracy and is more durable.

  • Ease of use
  • Preloaded sample injection mode, the injection time can be shortened to 5s, which greatly improves the efficiency.
  • A variety of injection modes combined with sample temperature control technology to satisfy different detection needs such as rare and unstable samples.
  • The dehumidification function is optionally equipped to avoid the generation of condensed water, effectively prevent the sample from being diluted, and ensure accurate results.
  • The maintenance is more convenient and efficient with the in-front injection valve.
