URN: COGSCIM2_13
Business Sectors (Suites): Scientific Manufacture
Developed by: Cogent
Approved on: 30 Mar 2017

Overview

This standard covers the competences you need to concentrate and diafiltrate harvested biomaterial in biomanufacturing downstream processing operations
using tangential flow filtration (TFF), in accordance with approved procedures. You are required to check the readiness of the manufacturing area and equipment to be used. You will be required to work to the relevant standard
operating procedures, legislation and organisational policy, and to follow Good Manufacturing Practice (GMP). You will be required to present records and details of your biomanufacturing work to the appropriate people.

You will be required to check that the work area and equipment are ready for use, and that the appropriate resources and services are available, as stated in the instructions and standard operating procedures you are given. You will concentrate and diafiltrate biomaterial in downstream processing operations. You will be required to separate biomaterial using filtration in accordance with instructions and procedures. You will also complete all the required documents and paperwork in accordance with these same instructions and procedures.

Your responsibilities will require you to comply with health and safety requirements and organisational policy and procedures for the biomanufacturing work that is undertaken. You will be required to report any
problems with the health and safety procedures that you cannot personally resolve, or that are outside your permitted authority, to the relevant people.

Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will enable you to adopt an informed approach to tangential flow filtration procedures. You will have an understanding of the harvesting by the
filtration process, in adequate depth to provide a sound background for carrying out the biomanufacturing activities to the required specification.

You will understand the safety precautions required when carrying out the biomanufacturing activities for scientific operations and processes. You will be required to demonstrate safe working practices throughout, and will understand your responsibility for taking the necessary safeguards to protect yourself and others in the workplace.


​This activity is likely to be undertaken by someone whose work role carries out Science/Bio manufacturing work activities. This could include individuals working in the following industries, Chemical, Pharmaceutical and Life Science industries.

K8 the types of handling and sorting system, and the procedures used for materials undergoing processing in the manufacturing facilities
K9 the importance of correct identification, and any unique organisational or manufacturing numbers
K10 the organisational requirements for maintaining the security of the workplace
K11 the lines of communication and responsibilities in your department, and their links with the rest of the organisation
K12 the limits of your own authority and to whom you should report if you have problems that you cannot resolve
K13 the basic principles of tangential flow filtration (TFF) operation
K14 how to set up a TFF system, insert the membrane and torque it correctly
K15 the procedure for preparing the TFF system using cleaning in place (CIP)
K16 the different methods that can be used for doing CIP
K17 how to conduct a clean water flux measurement test
K18 how to equilibrate the TFF system membrane with the required buffer solution
K19 how to add biomaterial to the TFF system tank, and how to operate the system correctly
K20 how to calculate trans-membrane pressure (TMP)
K21 how to recover biomaterial from the TFF system and membrane
K22 how to dispose of waste material correctly
K23 how to store filled biomaterial containers for further processing
