KNAUER’s new Liquid Handler LH 2.1 allows for the expansion of purification processes with the ability to combine sample injection and fraction collection in one device. A high capacity of sample and fraction vessels meets a flexible arrangement facilitating reinjection of samples to reach new levels of purification. The handler injects samples with minimal loss regardless of their volume – perfect for working with expensive compounds.
• Combine sample injection and fraction collection
• Inject small and large sample volumes with minimal loss
• Expand your vessel capacities
• Flexible arrangement of samples and fractions
• Reinject collected fractions to reach new levels of purity
