Bulk & Kilogram Manufacturing
Scale-up from research grams to multi-kilogram commercial batches, manufactured in-house under ISO 9001 and GMP guidelines.
QIANMIAO scales peptide production from research-scale milligrams through to multi-kilogram commercial batches, all manufactured in-house at our ISO 9001 certified facility in Qingdao. The same synthesis route, analytical methods and release specifications carry across scales, so material you qualify at gram scale behaves the same at kilogram scale.
Batch-to-batch consistency is the point of a bulk supplier. Standardized processes, documented audit trails and retained samples mean every lot is traceable and reproducible.
Scale-Up & Process Transfer
We develop the route at research scale, lock the process parameters, then transfer to production without changing the impurity profile.
- Research scale — 5 mg to 100 g for evaluation, method development and stability studies.
- Pilot scale — 100 g to 1 kg for process validation and registration batches.
- Commercial scale — multi-kilogram production runs with locked specifications.
Quality Control at Every Batch
Each batch is released only when all test results meet specification. The COA reports actual measured values, not specification limits.
- Purity — HPLC, typically ≥ 99% for catalog products.
- Identity — mass spectrometry molecular weight confirmation.
- Safety — endotoxin (LAL), microbial limits and residual solvents by GC where applicable.
- Traceability — documented audit trail and retained samples for every lot.

Frequently Asked Questions
What is the minimum order quantity?
Most catalog peptides start from 5 mg for evaluation. Bulk orders range from grams to kilograms. Contact us for product-specific MOQ.
Will a kilogram batch match the gram batch I qualified?
Yes. The synthesis route and release specifications are held constant across scales, and we retain samples from every lot so you can compare directly.
Can you provide free samples for evaluation?
We provide free COA samples for evaluation. Physical samples can be arranged in small quantities at competitive pricing.
