Why is it useful to have a membrane casting instrument for labscale use only?
Before scaling up, it’s crucial to optimize the membrane formulation and casting process. Large-scale production requires significant amounts of casting solution, which can be costly and lead to material waste if the formulation isn’t yet perfected. With a lab-scale instrument like MemCast, you can efficiently test and refine your membrane properties using smaller volumes, ensuring a smoother transition to full-scale production.
What tests are commonly performed after creating a lab-scale membrane?
After casting a membrane, researchers typically conduct various tests to evaluate its structure and performance, including:
Porometry – Determines pore sizes and pore size distribution.
Scanning Electron Microscopy (SEM) – Provides detailed imaging of membrane morphology.
Liquid filtration tests – Measures flux and assesses which particles are retained.
Why is the speed of membrane casting adjustable?
The casting speed needs to be adapted based on the viscosity of the membrane solution:
- High viscosity – A low casting speed is required to ensure uniform film formation and avoid defects.
- Low viscosity – A high speed can be used, as the solution spreads more easily and evenly.
What is the suitable range of viscosity for a casting solution?
The recommended/applicable range is from 100 mPa s up to 700 000 mPa s (0.1 Pa s – 700 Pa s => 100 cP – 700,000 cP). The values might vary depending on the solution.
Can membranes be cast on a substrate?
Yes, reproducible film layers can be prepared either as self-standing membranes (by coating directly onto surfaces like glass or stainless steel plates) or on various substrates, depending on the desired membrane structure and application. By using the optional glass casting plate with a special clamp, nonwoven fabric or other substrate layers can be easily secured, ensuring a stable and even coating process.
Why is uniform potting so important?
To ensure leak-free modules for further tests, as well as assure availability of large filtration surface.
What is the maximum pressure that the Tritan copolyester modules for the RotaMem can withstand?
The Tritan modules can withstand a maximum pressure of 2 bar. Therefore, after the potting process, the modules can be used in applications where the pressure does not exceed 2 bar.
