Our heart beats for membrane technology!
Choosing the right membrane and the right module for your desired project is the key to success.
We will find the best solution with you!
Alpha Plan has more than 25 years of experience in filter manufacturing - from the development and production of individual prototypes, to the manufacture of millions of hollow fiber modules per year, to the delivery of a fully automated production line.
Do you have a specific application in mind and want to test the approach quickly with a standard module? Would you like to start with your idea and test the basic concept?
Sometimes a standard hollow fiber filter is sufficient.
And if you need certain adaptations later on, we will be happy to do this for you. A selection of our standard membrane filters, which we have permanently in stock, can be found here:
Do you need a special membrane filter module that you cannot find here? Do you need a special module size, different connections or a different type of membrane?
Talk to us, we will find a customized solution for you.
Do you need a specific filter module for a specific application? Would you like to manufacture an entire cassette system including a membrane module? Do you need series production of over 100,000 modules? Are you perhaps thinking about setting up your own production line to ensure a constant supply?
Then Alpha Plan is the right place for you! Our competent project team of engineers from the fields of medical technology, biotechnology, physical engineering and quality management will develop the ideal product for you, taking series production into account.
All our filter modules are developed and manufactured in-house, making them a genuine Made in Germany product. Alpha Plan has production lines under clean room conditions at its disposal for this purpose. The hollow fiber membranes used are sourced from renowned German and Japanese membrane suppliers in order to offer you a wide selection of modules.
Depending on the number of modules required, we can respond very flexibly to your requirements, even if you only need a few prototypes or small batches. A decision for a manual, semi-automated or fully automated production process makes this possible.
Production takes place in a clean room under controlled manufacturing conditions, in accordance with the ISO-14644-1 Class 8 standard in the central production area and ISO-14644-1 Class 6 at the laminar flow workstation.
High quality and standardized quality assurance are the basis of our actions. Our production team is highly competent and pays attention to every detail. This is confirmed by our certified quality management system ISO 9001: 2015 and EN ISO 13485: 2016, as well as our excellent customer satisfaction.
