LabStak M37/38
The Alfa Laval LabStak® M37/38 is a flexible plate-and-frame test unit for ultrafiltration and microfiltration membrane processes. The unit utilizes support plates and flat sheet membranes of the same size as our full-scale membrane filtration modules. This makes the Alfa Laval LabStak® M37/38 a popular choice for process development, up-scaling, membrane testing, quality assurance and small-scale production. Optional plate sets are available for feeds of different viscosity / solids content
Handy and flexible
The Alfa Laval LabStak® M37/38 is designed to provide quick and precise evaluations in laboratories and other test facilities, while keeping equipment and set-up cost to a minimum.
This flexible unit, which is designed for plate-and-frame operation, can be fitted with the full range of flat sheet membranes available from Alfa Laval for ultrafiltration and microfiltration.
Option
For the LabStak® M37/38 Alfa Laval offers alternative plate set configurations which can be selected according to use.
- M37 plate set
For highly viscous liquids - M38H plate set
High channel, for medium viscous liquids - M38L plate set
Low channel, for low viscous liquids

运行原理
阿法拉伐的板框式模块设计有横跨膜表面的开放通道。进料流/滞留物流过这些开放通道。
膜本身由带有许多槽的中空板支撑，这些槽可收集渗透液，并通过渗透液收集管从模块中排出。
v板框式模块在锁环或锁条的帮助下使用膜本身将进料/滞留物密封，防止其混入渗透通道。这也避免了板组（plate stack）本身的任何泄漏风险。
