Introduction
Advanced Separation & Purification Solutions for Pharmaceutical Manufacturing
Pharmaceutical manufacturing requires precise separation, purification and concentration at multiple stages of the process. The right technology can help improve product recovery, reduce processing complexity and achieve consistent process performance.
Sanitech Engineers provides customized membrane and preparative chromatography systems for pharmaceutical applications. Depending on the process requirement, technologies such as microfiltration, ultrafiltration, nanofiltration, reverse osmosis, tangential flow filtration and preparative chromatography can be considered for suitable separation processes.
Our engineering approach considers the characteristics of the product, impurities, solvent system, concentration requirements, membrane selection and desired operating conditions before developing the system.
API Purification
API purification is the process of removing impurities, residual solvents, and by-products to obtain high-purity active pharmaceutical ingredients suitable for formulation.
Traditional purification methods such as aqueous washing and solvent extraction are time-consuming and resource-intensive.
Sanitech Engineers provides advanced membrane-based purification systems that streamline impurity removal with higher efficiency and lower operational costs.
Our customized membrane solutions ensure:
- High-purity APIs and HPAPIs
- Faster processing time
- Reduced solvent usage
- Improved product recovery
We tailor every system to match specific separation and processing requirements.
The careful elimination of contaminants is necessary to guarantee the manufacturing of high-quality medicines and intermediates. Aqueous washes and liquid extraction were two laborious methods used in the past for this API (active pharmaceutical ingredient) purification process. However, by providing state-of-the-art membrane technology, we at Sanitech Engineers have completely transformed the purifying process.
We promise to offer highly pure APIs and HPAPIs in a fraction of the time and at a lower operational cost thanks to our sophisticated membrane technologies. We customise our membrane systems to each client’s unique separation and processing needs.
For dependable, economical, and successful impurity removal from APIs, choose Sanitech Engineers so you can concentrate on producing the best pharmaceutical products and intermediates.

We at Sanitech Engineers have a proven track record of providing innovative peptide purification solutions. Even for peptides with widely differing sources and levels of complexity, our sophisticated membrane and preparative chromatography technology is engineered to provide outstanding purification quality.
You can rely on Sanitech Engineers to deliver dependable and effective peptide purification with our creative approach, guaranteeing the highest quality standards for your pharmaceutical and cosmetic products.
FAQs
Peptide purification is the process of separating target peptides from impurities such as truncated sequences, synthesis by-products, salts, and solvents. High-purity peptide purification is essential for pharmaceutical, biotech, and therapeutic peptide applications.
Common pharmaceutical purification methods include:
Preparative chromatography (RP-HPLC, ion exchange, size exclusion)
Membrane filtration (ultrafiltration, nanofiltration, diafiltration)
Crystallization and precipitation
Solvent extraction and distillation
These methods are selected based on molecular size, charge, solubility, and purity requirements.
Peptides are widely used as therapeutic agents due to their high specificity and biological activity. Pharmaceutical peptide applications include treatments for metabolic disorders, cancer, infectious diseases, hormonal therapies, vaccines, and targeted biologics.
Desalting
At Sanitech Engineers, we understand how crucial salt removal is to the purifying procedure. We specialise in ion balance and molecule size in desalting applications. We provide high-end desalting solutions by utilising our state-of-the-art membrane and chromatography technology.
Our state-of-the-art membrane methods offer the benefit of reduced running costs in addition to ensuring an environmentally safe purification solution.
At Sanitech Engineers, we’re committed to going above and beyond for our customers by providing efficient and reasonably priced desalting solutions for a variety of uses.
FAQs
Desalting is the removal of salts and low-molecular-weight impurities from protein, peptide, or API solutions. It is commonly performed using size-based separation techniques such as membrane filtration or size exclusion chromatography to improve product purity and stability.
While both processes use similar technologies:
Desalting removes salts and small molecules from a solution.
Buffer exchange replaces one buffer system with another.
In buffer exchange, the system is equilibrated with the target buffer, whereas desalting typically uses water or a low-salt medium.
A desalting column rapidly separates large biomolecules (proteins or peptides) from salts and small contaminants. It is often used as a preparatory step before chromatography, formulation, or analytical testing.
Product concentration by solvent removal
The difficulties the pharmaceutical business faces in concentrating solutions by solvent removal are acknowledged by Sanitech Engineers. Being industry leaders, we provide cutting-edge membrane techniques that are both extremely sophisticated and very user-friendly. Our cutting-edge solutions are excellent at effectively removing solvents from the product, guaranteeing a smooth and effective concentration procedure.
FAQs
Solvent removal is a downstream concentration process that increases product strength by eliminating excess solvent. It is commonly achieved using membrane filtration (RO/NF), evaporation, or distillation, depending on solvent type and product sensitivity.
Solvent extraction (liquid-liquid extraction) separates compounds based on their solubility in immiscible liquid phases. It is widely used in API manufacturing to remove impurities or recover target compounds during purification.
Pyrogen removal
For biotech companies looking to guarantee the safety and purity of their finished products, pyrogen elimination presents a major hurdle. Modern Ultrafiltration and Nanofiltration systems have been created by Sanitech Engineers to exactly meet this crucial need and produce final goods free of pyrogen. Reliable and long-lasting performance is guaranteed by the remarkable durability with which our systems are constructed.
We provide bespoke Ultrafiltration and Nanofiltration solutions that are suited to your particular requirements because we understand how unique every biotech application is. You can rely on Sanitech Engineers’ solutions to meet the strictest safety and regulatory compliance requirements while maintaining the purity and quality of your final goods.
FAQs
Pyrogens, including bacterial endotoxins, are removed using advanced purification techniques such as ultrafiltration, nanofiltration, and specialized depyrogenation processes. These methods are critical for ensuring the safety of injectable and parenteral drug products.
Pyrogens are fever-causing substances, most commonly bacterial endotoxins derived from Gram-negative bacteria. Strict removal of pyrogens is mandatory in pharmaceutical manufacturing to comply with regulatory safety standards.
