HPLC Pumps (Solvent Delivery Unit)
UHPLC-Highest Efficiency Series
Shimadzu offers a wide variety of pumps ranging from analytical (100 µL) to preparative (150mL) flow rates. Prominence, Nexera XR, and Nexera X2 series pumps allow analyses from traditional HPLC to UHPLC to preparative LC. Shimadzu also offers an inert pump for a complete metal free flow path improving analysis for biological or bromate applications.
The LC-30AD provides superior UHPLC performance over a wide range of analytical flow rates. With precise solvent delivery and ultra-fine gradient step formation, the pump provides the utmost in gradient accuracy and repeatability. The ultrahigh-pressure capacity (up to 130 MPa) makes it possible to use columns packed with sub-2μm particles.
HPLC – Extended Efficiency Series
The LC-20ADXR offers an extended pressure tolerance over traditional HPLC (up to 66 MPa) while maintaining stable solvent delivery with reliable performance across an extensive analytical flow rate range. This pump also includes automatic rinsing to ensure improved plunger seal life under high-pressure delivery conditions.
HPLC – Standard Efficiency Series
The LC-20AD provides excellent performance over the traditional analytical flow rate range. Two LC-20AD pumps may be used to achieve high-pressure gradient elution for the utmost in gradient accuracy. Alternatively, one LC-20AD pump may be outfitted with a LPGE valve for low-pressure gradient elution.
The LC-20AT offers robustness in an economical design—a workhorse for routine daily use. Two LC-20AT pumps may be used to achieve high-pressure gradient elution for the best gradient accuracy. Alternatively, one LC-20AT pump may be outfitted with a LPGE valve for low-pressure gradient elution.
The LC-20AB is a binary, high-pressure gradient solvent delivery unit that incorporates two LC-20AD pumps into one compact unit. The space-saving design and superior performance of the LC-20AD pump provide precise and accurate high-pressure gradients.
The LC-20Ai offers reliable, low pulsation pumping but with a metal-free flow path for improved accuracy and sensitivity required by bio-inert and ion chromatography applications. All wetted parts are made from non-metal components, such as PEEK.
HPLC – Preparative Series
The LC-20AR offers an extended flow rate range (up to 20 mL/min) suitable for the collection of chromatographic fractions on a semi-preparative scale (~ 50 milligrams). This pump also provides reliable analytical flows.
The LC-20AP offers an extended flow rate range (up to 150 mL/min) suitable for the collection of chromatographic fractions on a preparative scale (several hundred milligrams).
