The concept of modularity (using standard modules to customize the lay out of the bioreactor) has been extended to the stainless steel pilot plant bioreactors and fermentors. The vessels are cGMP and comply with different pressure codes throughout the world. The systems are fully documented and delivered with all necessary documentation to support easy validation.The Pilot Systems are divided in two types ranging in sizes of 20 to 140 liter
The MiniBio range of bioreactors (250 ml, 500 ml and 1000 ml total volume) is a true scale down of the laboratory scale bioreactors in the 1 to 15 liter range. The MiniBio systems have the same flexibility as the laboratory scale bioreactors. This means that the MiniBio systems can be customized to fit the demands of any process.
An integrated, easy-to-use, and cost-effective technology platform for the rapid handling and growth of large numbers of microbial strains, clonal libraries, mutant banks, and cell lines in 24 or 96-well microtiter plates.
Single-Use bioreactors are increasingly favored for the economic advantages they offer. Many mammalian cell based biotech producers are moving to disposable modules, pre-sterilized and qualified according to regulatory requirements. Benefits of single-use bioreactors include faster facility set-up, reduction of down time, simplified validation, and more efficient use of plant floor space.
Particle Size Distribution is a very important parameter to be tested before drug product release. A correct particle size distribution ensures the bioavailability of the active drug on the target site of action. An unapproved particle size distribution may lead to waste of drug doses and decreased efficacy of the dose. For example, a very fine particle/droplet distribution of Nasal Spray (<10 micron) will deposit more spray droplets in the lungs and gastrointestinal tract than the nasal passageway which is the target site of action. To ensure maximum deposition of the spray droplets in the nasal passageway the particle size should be more than 10 micron. Therefore, particle size distribution analysis is an obligatory test before product release.
The devices used for inhaled and nasal drug delivery are collectively referred as Orally Inhaled and Nasal Drug Products, OINDPs. The OINDPs comprises Inhalers (metered dose, dry powder and aqueous droplet), Nebulizers (jet, ultrasonic and vibrating mesh) and Nasal (aqueous based, dry powder and propellant based).
Have you ever wondered what shape the spray or aerosol you have really produces from your MDI/DPI or NSP? For a variety of reasons, these drug delivery methods need characterization. Following is a piece of information from CMC guideline on the importance of Spray Pattern and Plume Geometry analysis. Characterization of spray pattern and plume geometry is important for evaluating the performance of the pump. Various factors can affect the spray pattern and plume geometry, including the size and shape of the nozzle, the design of the pump, the size of the metering chamber, and the characteristics of the formulation. Spray pattern testing should be performed on a routine basis as a quality control for release of the drug product. However, the characterization of plume geometry typically should be established during the characterization of the product and is not necessarily tested routinely thereafter.

Dose content uniformity (DCU) is the test which ensures the uniform distribution of active drugs in the MDIs/DPIs/NSPs/Nebulizers of a batch. The same test for Nasal Spray (NSP) is called Spray Content Uniformity (SCU) which is also performed within a batch. The test checks the active drug content of a number of MDIs/DPIs/NSPs/Nebulizers from a batch. For Example, 10 MDI units are randomly collected from a lot. Then the 10 MDIs are actuated in 10 different collection tubes to collect the doses.
