title: Automated lab-scale production of PVA/PEG-enzyme immobilisates.
abstract: Entrapment of biocatalysts by cryogelation is a gentle method to extend the scope of biocatalysis. To foster the use of this versatile method we devised an automated injector for the production of PVA/PEG beads. The device consists of a thermostated reservoir connected to a programmable injector nozzle and an agitated receiving bath for the droplets. This lab-scale production unit yields up to 1500 beads with immobilized enzyme per minute with a narrow size distribution and good roundness.
