Singapore: GE Healthcare has launched a flexible fraction collector and robust and intelligent sample pump that is specifically designed to enhance ÄKTA pure, the modular chromatography system for flexible, reliable and intuitive protein purification.
Designed to handle both air and liquid, the sample pump together with the sample inlet valve, provides fast, automated, and complete loading of up to seven samples.
The air-sensor integrated into the valve detects the final drop of sample, automatically preventing the introduction of air whilst ensuring the complete sample reaches the column. The sample pump also has a robust wash program that removes any air introduced between samples.
In order to secure precious samples from dust and contaminants, the fraction collector is covered and it supports flexible combinations of collection vessels from deep-well plates to 250 ml bottles.
In addition to spillage-free collection across the entire flow-rate range of ÄKTA pure, the fraction collector has inbuilt automatic detection of collection vessel type to ensure sample security.
