. Written Quality Assurance
Our company specializes in the research-grade peptide raw material development, purification, and supply. We mainly offer research peptide products. To standardize business practices, protect the rights and interests of research customers, and adhere to industry compliance standards, we make the following solemn quality commitment for all our research-grade peptide products:
1. Genuine Business Commitment (Core Bottom Line)
All the peptide products on sale in our company are laboratory research-grade raw materials.
2. Raw Material Quality and Purity Commitment
All research-grade peptide products are synthesized using high-quality raw materials and follow standardized production processes throughout the process. All products undergo HPLC (High Performance Liquid Chromatography) purity testing. The purity of regular products is ≥ 95%, and the purity of high-end refined batches can reach 98% - 99%. The products have no impurities, no odor, no turbidity or sedimentation, stable molecular structure, and highly unified purity, molecular weight, and physicochemical indicators across batches, ensuring accurate and repeatable research experiment data.
Each batch of products can provide a corresponding COA (Certificate of Analysis) quality inspection report, including complete detection data such as purity testing, molecular weight verification, and impurity screening. This ensures one inspection per batch, full traceability, and eliminates issues such as inferior product substitution, adulteration, and batch confusion.
3. Quality Control Commitment During Production and Storage
The production, freeze-drying, packaging, and sealing of products are completed in a clean environment, strictly controlling the residual of harmful substances such as endotoxins, microorganisms, and heavy metals. All products are sealed in vacuum vials for freeze-drying and are protected from light, moisture, and sealing. They perfectly retain the molecular activity of the peptides. We strictly follow the classification storage standards: unfrozen-dried products are stored at -20℃ in a dark and dry environment, and reconstituted products are stored at 2 - 8℃ for refrigeration. This prevents degradation and inactivation of the products due to high temperature, light exposure, repeated freeze-thawing, etc., ensuring the stability of the products within the validity period.
4. Quality Assurance Commitment for After-sales
Our company guarantees that all products are strictly inspected before leaving the factory and are delivered without defects. If the customer receives the product and, through formal testing, discovers any quality issues such as insufficient purity, product deterioration, packaging damage, or mismatch with the order, we will unconditionally provide free re-delivery, replacement services, and bear the corresponding after-sales responsibilities. At the same time, we provide professional technical support for product storage, reconstitution, and consultation on physicochemical parameters to help customers successfully conduct research experiments.
