More questions about single-use bags
Will your bags fit our existing hardware?
Send us the item number or drawing of your current bag and the model of your hardware. We build a matching bag with your existing connectors and check the fit before production.
Which film do you use for cell culture media?
As standard a multilayer PE/EVOH film with gas barrier, free of animal-derived components and USP Class VI. For special chemical resistance or freezing we offer other film structures.
How are the bags sterilised and documented?
They are made in an ISO Class 7 cleanroom and gamma irradiated to SAL 10⁻⁶ (ISO 11137). Each batch comes with CoA and CoO; a leachables, extractables and tox validation guide is available.
Is there a minimum order quantity?
Yes: pilot lots start at 100 units, and serial supply follows after drawing approval. Typical lead time: 2–3 weeks for 100 units.

Frequently Asked Questions
What is the difference between 2D and 3D bioprocessing bags?
2D bags are flat for storage and freeze-thaw. 3D bags have a cuboid shape for larger volumes and bioreactor use — better space efficiency above 20L.
What is a single-use bag assembly?
A pre-configured system combining a bioprocess bag with tubing, connectors and optional filters — ready to use without in-house assembly. Available in 2D format (150 mL–50 L) and 3D format (100 L–1,000 L).
What container sizes are available?
Stainless steel container systems in 200L, 500L and 1000L with integrated single-use liner. Other sizes on request.
Can bags be customised?
Yes — custom port configurations, tubing assemblies and bag dimensions available on request. Contact us with your specifications.
