Quality Assurance
Every peptide we produce meets the highest standards of purity and consistency.
Our Quality Philosophy
At Pepitiva Biolabs, quality assurance is not merely a department — it is the foundation of our entire operation. We recognize that the integrity of your research depends directly on the quality of your reagents. A contaminated or impure peptide can invalidate months of experimental work, waste valuable resources, and lead to unreliable conclusions. This understanding drives every decision we make, from supplier selection through final product release.
Our quality system encompasses raw material qualification, in-process synthesis monitoring, multi-method final product testing, environmental controls, documentation standards, and cold-chain logistics. We invest significantly in analytical instrumentation and trained personnel to maintain these standards consistently across every batch we produce. The result is a product line that researchers can trust to deliver reliable, reproducible results in their experimental protocols.
Our Standards
HPLC Analysis
Every batch undergoes High-Performance Liquid Chromatography analysis ensuring purity levels ≥98% for all products.
GMP Compliant
Our manufacturing partners follow Good Manufacturing Practices to ensure consistency, safety, and traceability.
Certificate of Analysis
Each product ships with a detailed COA including purity data, mass spectrometry results, and batch identification.
Cold Chain Shipping
Products are shipped with thermal packaging and temperature indicators to maintain peptide integrity throughout transit.
Full Traceability
Every batch is traceable from raw materials to final product with unique lot numbers and complete documentation.
Purity Guarantee
We guarantee ≥98% purity on all peptides. If a product does not meet specifications, we replace it at no charge.
Our Process
Sourcing
Raw materials from verified, audited suppliers with full certificates of origin and quality documentation.
Synthesis
Solid-phase peptide synthesis (SPPS) in controlled environments following strict SOPs and GMP guidelines.
Testing
Multi-stage analysis: HPLC purity testing, mass spectrometry confirmation, endotoxin testing, and sterility checks.
Packaging
Lyophilized in sterile vials under nitrogen atmosphere, sealed with tamper-evident closures and lot tracking.
Analytical Instrumentation
Our analytical laboratory is equipped with high-performance liquid chromatography (HPLC) systems with UV and fluorescence detection for purity determination, electrospray ionization mass spectrometry (ESI-MS) for molecular identity confirmation, and lyophilization equipment for controlled freeze-drying. These instruments are maintained under regular calibration schedules and operated by trained analytical chemists to ensure accurate, reproducible results for every batch tested.
