Plasma Fractionation
Saving a life is an ultimate activity and plasma fractionation is one the most essential biotechnological approach to make life-saving therapeutic proteins. For such an important lifesaving product it is prime important to have a sustainable technology. Apart from this, the equipment or system is crucial which should be installed in a GMP facility. The footprint wrt the facility available also matters in decision making.
With more than 3.5 decades of manufacturing expertise, our state-of-the-art products, such as TFF (Tangential Flow Filtration) and Preparative Chromatography systems, are made to outperform traditional techniques in terms of efficiency, cost-effectiveness, and smooth automation.
You can expect increased productivity and more efficient operations with our TFF cassettes. By ensuring continuous processing, the Tangential Flow Filtration system reduces downtime and increases yield. For the chromatographic separation of plasma components, our DAC LPLC (Low-Pressure Liquid Chromatography), Static MPLC (Medium Pressure Liquid Chromatography), and LPLC (Low-Pressure Liquid Chromatograph) columns are painstakingly designed to provide outstanding purity and yield.
FAQs
Plasma fractionation is the separation of human blood plasma into its individual protein components using controlled physical and chemical methods. The process commonly involves filtration, precipitation, and chromatography to isolate therapeutic proteins such as albumin, immunoglobulins, and clotting factors for medical use.
Fractionated plasma refers to plasma that has been separated into distinct protein fractions, each enriched with specific proteins. These fractions are further purified and formulated into life-saving biopharmaceutical products.
Plasma is separated from whole blood using a plasmapheresis machine, which removes plasma while returning red blood cells and other components to the donor. Downstream purification of plasma proteins is then carried out using filtration and chromatography systems.
Recombinant proteins
Sanitech Engineers specializes in manufacturing innovative systems for the purification of recombinant proteins. Our state-of-the-art technology makes use of membrane systems for Tangential Flow Filtration (TFF) and Preparative Chromatography.By attaching target proteins to a stationary phase, removing contaminants, and eluting the pure protein, preparative chromatography uses concepts like affinity, ion exchange, and size exclusion to separate target proteins from complex mixtures.
Proteins are concentrated and purified based on size and molecular weight using Tangential Flow Filtration membrane systems, which are based on pressure-driven filtration. Sanitech Engineers has the capacity and know-how to create solutions that are specifically tailored to your needs and products.
FAQs
A recombinant protein is a protein produced using genetically engineered host cells (such as bacteria, yeast, or mammalian cells) into which the gene encoding the desired protein has been inserted. This technology enables large-scale, controlled production of therapeutic proteins.
Recombinant proteins are widely used in biopharmaceuticals as therapeutic hormones, enzymes, vaccines, growth factors, and antibodies. Common applications include treatments for diabetes, cancer, autoimmune diseases, infections, and rare genetic disorders.
Purification of mAbs and Vaccines
Sanitech Engineers has created sophisticated chromatography systems that are excellent for vaccine purification as well as intermediate purification and polishing of protein solutions containing vital biomolecules like albumin, lgG, lgM, mAbs, and hormones. These state-of-the-art systems offer many benefits, such as increased production capacity, reduced space needs, and easier cleaning and maintenance procedures.
Our Preparative Chromatography systems provide the pharmaceutical and biotech sectors with increased productivity and cost-effectiveness while guaranteeing the best possible purification of monoclonal antibodies and vaccines by effectively handling a broad variety of biomolecules.
FAQs
Purification of monoclonal antibodies and vaccines is essential to remove host cell proteins, DNA, endotoxins, and process impurities. High-purity mAbs and vaccines are critical for ensuring patient safety, product efficacy, and regulatory compliance in biopharmaceutical manufacturing.
Biopharmaceutical purification typically uses a combination of:
Preparative chromatography systems (Protein A, ion exchange, polishing steps)
Tangential flow filtration (TFF) systems for concentration and diafiltration
These technologies enable scalable, reproducible, and GMP-compliant purification processes.
Extraction from fermentation broth
Fermentation is one of the quickest and easiest also green process to manufacture value added products using microorganisms. All attempts are made to maximally produce it. But the efforts go vain if the produce molecule is not extracted or separated from biomass to the fullest.
Sanitech Engineers have built themselves as one of the successful membrane filtration system manufacturers having global standards. They have the entire membrane filtration spectrum.
Further they have collaborated with SFE Process, France for supercritical fluid process which uses supercritical CO2 for extraction and purification of desired molecules.

Their team of professionals can offer specialised solutions made to fit your particular requirements, guaranteeing successful and economical procedures.
FAQs
Extractive fermentation refers to the recovery and separation of valuable biomolecules directly from fermentation broth. The process uses membrane filtration technologies to clarify, concentrate, and partially purify target products such as proteins, enzymes, or peptides before downstream purification.
Specialized bioprocess equipment manufacturers provide systems for extraction from fermentation broth, including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis systems. These systems are designed to handle complex biological feeds and support scale-up from lab to commercial production.

FAQs
Insulin is purified after biosynthesis through a series of downstream processing steps designed to achieve very high purity. These steps typically include chromatography techniques such as HPLC, preparative chromatography, and low-pressure liquid chromatography (LPLC), along with membrane filtration for concentration and buffer exchange. The process removes host cell proteins, process impurities, and variants to meet strict biopharmaceutical quality and regulatory standards.
Downstream processing includes the separation, recovery, concentration and purification steps used after biological production to obtain the target biomolecule at the required quality. Depending on the product, the process may include clarification, membrane filtration, TFF, diafiltration and chromatography.
Common filtration technologies include microfiltration for clarification and cell removal, ultrafiltration and TFF for concentration and diafiltration, and other membrane processes for application-specific separations. Chromatography is commonly used when higher-resolution purification is required.
TFF is commonly used to concentrate proteins and other biomolecules and to perform diafiltration or buffer exchange. Because the feed flows parallel to the membrane surface, TFF is suitable for many cross-flow biopharmaceutical concentration and purification processes.
