. kyPilot Laboratory Equipment for Membrane Filtration LabStak® M39L/H . The LabStak® M39L/H is specially developed for ultrafiltration and microfiltration of highly viscous products and fermentation broths. The module is ideal for a range of uses in industries that include biotechnology, pharmaceuticals, and food and beverages. To meet the demands experienced here, the module is designed for optimized flow dynamics, low energy consumption and pressure operation. The LabStak® M39L/H is ideal for process development, scale-up, membrane testing, quality assurance and small-scale production. It can be fitted with the whole range of flat sheet membranes for ultrafiltration and microfiltration. The LabStak® M39L/H is designed to provide rapid, precise process evaluations in laboratories or other test facilities, while keeping equipment and set-up costs to a minimum. The module utilizes the same size support plates and membranes as those found in the full-scale plate-and-frame systems. It consists of an M39 frame and has two alternative plate set options – M39L and M39H – in order of increasing channel height. Advantages • Rapid, easy exchange of membranes • Can be coupled to the by-pass stream of an industrial plant • Different channel height options to optimize flow and pressure • Simultaneous test of up to five different membrane types • Lowinternalvolume • All components manufactured in compliance with FDA regulations • Flexiblesystemdesign • Flexible membrane area between 0.2 and 1.0 m2 • High operating temperatures (up to 80°C) Plate set options The module consists of a full-size plate-and-frame cross-flow membrane filtration module, type LabStak® M39. The module can be equipped with alternative plate set configurations, according to use. M39L Low channel, for low and medium viscous liquids, code no.
