The new Thermo Scientific Accela 1250 pump features Force Feedback Control (FFC) which eliminates the need for pulse dampening while improving flow accuracy and gradient precision under extreme operating conditions.
The Accela 1250 pump is designed to operate at a top pressure of 1250 bar with flow rates of up to 2ml/min, reducing run times and improving productivity. This makes it the ideal choice for U-HPLC analysis and applications requiring flexibility between standard HPLC and U-HPLC capabilities. The improved pump also offers increased performance with significant baseline stabilisation and improved retention time reproducibility.
Thermo Fisher Scientific said that Accela 1250 pump enhances the already powerful Accela LC, which provides fast, efficient chromatographic separations over an expansive range of flow rates and pressures.
Andrew Altman, director of liquid chromatography at Thermo Fisher Scientific, said: “We are delighted to bring enhanced U-HPLC to our customers. The pressure capacity and operational performance offered by the Accela 1250 delivers maximum operating pressure, and the unique Forced Feedback Control redefines U-HPLC performance.”
