Intern - (Physical) Chemistry - PATS

Oss, Netherlands

Job Description

Are you looking for an internship where you are free to take initiative? Would you like to experience working in one of the biggest multinationals in the pharmaceutical industry? We are looking for a 4th year bachelor (HBO) or master student of (physical) chemistry who is searching for a challenging internship in our innovative company?

Your internship project

To assure the continuity of the supply of all raw materials for a protein crystalline drug product the seed crystals must be replaced by an alternative source. Our drug product manufacturing uses seed crystals to control the crystallization of the API.

As an intern you are responsible to optimize an alternative manufacturing method for the crystalline seeds:

Identify the critical process parameters and corresponding set-points to control the particle size and crystallinity of the protein seed crystals Prepare the final protein drug product at lab scale to compare the effectiveness of your alternative protein crystal seeds in controlling the crystallization of the final protein crystalline drug product

The commercial manufacturing process of the drug product is downscaled to 0.7 L using a Mettler Toledo Optimax labreactor. This reactor set-up is also evaluated as a representative model to simulate the commercial aseptic prepartion of the protein drug product.

Your responsibilities

  • Perform the lab scale experiments to screen for the critical process parameters and optimize the set-points of the critical process parameters for manufacturing of the alternative protein seed crystals.

  • Prepare the final protein drug product at lab scale to evaluate the effectiveness of your alternative seeds against no seeding and seeding with the current source of protein seed crystals.

  • Analyse the resulting material with a.o. laser diffraction, optical microscopy, crystallinity and other techniques

  • Evaluate the results and suggest adjustments

  • Providing a fresh perspective within the department: your opinion matters.

The above-mentioned responsibilities are an indication of what you will be doing after proper onboarding and initial learning and development. This provides you with the opportunity to learn and hereafter perform tasks independently. In consultation with your supervisor, you could take on additional tasks and responsibilities.
