  5. Enhanced protection of product molecules and parts
  6. Simplified inlet and outlet connections
  7. Multiple options: 50L | 100L | 200L | 500L | 1000L

Applications in Biopharma

Upstream Processing

Single-use mixing systems play a vital role in:

Here is a new version of the text provided:

Media Preparation

Ensures the uniform dissolution of powdered nutrients in WFI, which is directly linked to improved cell growth and productivity.

Buffer Preparation

Ensures precise and uniform mixing for the pH adjustment during cell culture and fermentation.

 Cell Culture Applications

Guarantees the sterility and uninterrupted consistency of media preparation and storage.

Process & Fluid Transfer

Allows for safe and uncontaminated transfer of process liquids.

 Downstream Processing

Mixer systems are also essential in:

  1. Buffer & Reagent Preparation
  2. Mixing helps in chromatographic and filtration operations.
Process Intermediates

Used in the purification steps to hold and mix intermediate bulk solutions.

Virus Inactivation

Ensures consistent interaction between the product and the inactivation agents.

Final Formulation

Mixing of APIs and excipients is done in a controlled and gentle manner to reduce shear stress and protein aggregation.

Fill-Finish Operations

Ensures the mixture is homogeneous prior to sterile filling into vials or syringes.

Compliance & Certifications

  1. Designed for compliance with international regulators:
  2. ISO 11137 – Sterilization Validation
  3. USP <87> – Biological Reactivity (In Vitro)
  4. USP <88> – Biological Reactivity (In Vivo)
  5. USP <661> – Plastic Packaging Systems
  6. Extractables & Leachables Studies

These certifications provide assurance for the safety of materials, biocompatibility, and market clearance in compliance with global regulations.

The Role of Advanced Polymer Solutions

Maintaining sterility and chemical compatibility is critical, and high-performance polymer components like silicone tubing, single-use assemblies, gaskets, and custom molded parts are crucial in achieving this.

Ami Polymer offers cutting-edge polymer solutions for the biopharmaceutical industry, enabling safe, scalable, and compliant mixing technologies.
