NiTech’s batch evaluator range offers customers interested in utilising the potential benefits of NiTech’s mixing technology to test their process in a low-volume, lower investment risk platform. It allows process parameters to be optimised using minimal material before being reliably scaled-up to a DN15, or larger, vessel.
They operate by either oscillating a fixed volume of fluid over static baffles or by oscillating dynamic baffles through an isolated volume of fluid. The DN15 model is designed to give an easy expansion towards the continuous DN15. The DN25/DN40 model, with its interchangeable glassware, gives a versatile platform to test screen multiple processes to determine those suited to NiTech’s technology. The DN60 models are designed to promote gas-liquid interactions (e.g. hydrogenation reactions), via a long tube, with a magnetically driven oscillator (i.e. no dynamic seals). The oscillatory baffled mixing breaks bubbles, increasing gas hold-up within the liquid and contact area.
