Biological Raw Materials for Cell Culture, Bioprocessing & Diagnostics
SeamlessBio supplies sera, albumins, cell culture media and single-use bioprocessing systems to biopharma, CRO, ATMP and IVD manufacturers. Our sera are processed and documented at our facility in Passau, Germany — traceable to source, with the paperwork your QA team needs for supplier qualification.
A Raw Material Supplier, Not Just a Distributor
In regulated environments, raw material variability is expensive. An unannounced lot change, missing paperwork or a broken cold chain delays validation and release — and can trigger costly requalification.
That is why we built our supply around the requirements of purchasing and quality assurance teams, not just around a price list.
What You Get
- Consistent lots — test free samples, then reserve your qualified lot for up to 36 months with no prepayment.
- Processing in Germany — sterile filtration, endotoxin and mycoplasma testing as standard.
- Documentation from one source — CoA, SDS, donor screening and TSE/BSE statement per lot.
- Traceability — certificate of origin for animal-derived materials, EU-sourced human serum with full donor documentation.
- A direct contact — technical advice from people who know the products, no ticket system.
