2. Standardized R&D & QC Laboratory Environment & Supporting Facilities
2.1 Scientific Partitioned Laboratory Layout
TanHong owns an integrated self-operated laboratory complex spanning over 3,800 square meters, scientifically split into physically separated independent functional zones to completely eliminate cross-contamination risks in different experimental links:
- Synthetic Preparation Laboratory: Equipped with standalone fume hood workstations for peptide coupling, chain assembly and target compound cleavage reactions; independent operating positions are assigned for different sample batches to prevent cross mixing.
- Chromatography Purification Zone: Dedicated area equipped with analytical and preparative HPLC systems for target component separation, gradient elution and high-purity enrichment of synthetic samples.
- ISO 7 Dust-Free Freeze-Drying Clean Workshop: Constant-temperature low-particle clean space for vacuum freeze-drying of peptide powder, sterile split filling and airtight vial sealing of finished lab samples.
- Central Quality Control Testing Lab: Unified testing area responsible for batch identity confirmation, purity quantification, residual component screening, heavy metal limit detection and microbial indicator inspection.
- Multi-Tier Constant-Temperature Sample Storage Room: Layered temperature-controlled storage space for raw material inventory, finished freeze-dried reagents and batch retention test samples.
- Classified Experimental Waste Treatment Chamber: Closed independent space for sorting, neutralizing and temporary standardized storage of liquid and solid lab waste before handover to certified professional waste disposal service providers.
- Technical Document & Sample Archive Room: Constant-humidity dry storage area for long-term preservation of batch test reports, full experimental operation logs, retention samples and official technical files to realize complete batch traceability.
All functional zones adopt separated personnel access passages and independent air circulation systems. All staff must complete two-stage air shower purification before entering core dust-free processing zones. Workflows for raw material handling, finished product packaging and waste disposal are strictly isolated to avoid cross-contamination between different compound varieties and production batches.
2.2 24-Hour Intelligent Constant Environmental Control System
Each lab functional zone is fitted with uninterrupted intelligent environmental monitoring networks featuring real-time data recording and automatic early warning alerts. Core environmental parameters are precisely stabilized to avoid structural degradation of temperature-sensitive freeze-dried peptide samples during synthesis, purification and storage:
- Constant Temperature Regulation: The whole laboratory complex maintains a steady temperature range of 20–24°C; the ISO 7 freeze-drying clean workshop supports fine adjustment within ±0.5°C to prevent thermal damage to fragile peptide solids.
- Humidity Stabilization: Integrated automatic dehumidification and humidification equipment locks relative humidity at 40%–55% all year round, effectively avoiding powder caking, static interference and moisture-triggered structural breakdown of freeze-dried solid reagents.
- Air Purification & Positive Pressure Control: Multi-layer HEPA high-efficiency air filtration equipment is installed inside ISO 7 clean zones to maintain stable 5–10 Pa positive internal pressure, blocking external unfiltered air and airborne particulate pollutants. Non-clean experimental zones are equipped with independent exhaust fume hoods with activated carbon solvent adsorption filters to purify volatile organic waste gas before outdoor emission.
- Full-Cycle Real-Time Monitoring Sensors: Wireless monitoring sensors are deployed throughout all lab areas to track temperature, humidity, airborne particle concentration, pressure difference and exhaust gas levels 24 hours every day. All environmental operation data is automatically stored on the laboratory cloud server for a minimum of 7 years, forming traceable environmental archives for every single production and testing batch. The system will instantly send graded alarm reminders to on-site supervisors and remote management terminals once any index exceeds standard thresholds for rapid on-site disposal.
All lab spaces adopt seamless anti-corrosion epoxy wall coatings and non-porous stain-resistant vinyl flooring, which supports quick daily wiping and disinfection without chemical residue buildup. All experiment countertops use imported acid-proof polypropylene panels, resistant to common organic solvents and acid-base reagents, simplifying daily sanitation maintenance and extending equipment service lifespan.
2.3 Complete Precision Laboratory Instrument Configuration
We deploy a full lineup of internationally recognized precision synthetic and analytical instruments to finish all independent in-house development and batch testing, without outsourcing core identification work to third-party institutions:

All precision testing instruments receive mandatory semi-annual calibration by officially authorized third-party metrology institutions, with complete calibration certificates filed for inspection. Daily pre-operation debugging, full operation logging and post-use maintenance are standardized compulsory procedures recorded in dedicated equipment ledgers to guarantee consistent, accurate test data output.
2.4 Standardized Laboratory Operation & Safety Compliance Management
The company has formulated comprehensive Standard Operating Procedures (SOPs) covering every single laboratory workflow, including raw material incoming inspection, synthetic feeding, chromatographic purification, vacuum freeze-drying split filling, finished product quality testing, sample storage and classified waste disposal. All laboratory technicians complete systematic professional training and pass formal assessment before independent operation; new recruits must finish a three-month mentor-led internship to fully master all safety specifications and standardized operation rules.
Strict hierarchical access permission control is implemented across the entire laboratory complex: core dust-free processing workshops and low-temperature sample repositories are only accessible to authorized R&D and QC staff with exclusive access credentials. Visitor entry requires advance formal written application, accompanied by internal supervisors throughout the visit, and mandatory full disposable sterile protective gear at all times inside lab areas.
Fixed morning and evening sanitation disinfection shifts are scheduled for daily laboratory management: all workstations, instrument surfaces and ground are cleaned with neutral bactericidal detergent after daily work hours; ISO 7 clean workshops run full overnight air circulation purification cycles to sustain low-particulate environmental standards. Full classified waste sorting is strictly executed: organic solvent waste, solid chemical residues and biological test waste are separately collected in sealed labeled containers, then transferred monthly to licensed professional hazardous waste disposal organizations for centralized processing, with complete transfer records archived to comply with international environmental protection regulations.
A dedicated full-time laboratory safety management team carries out daily patrol inspections covering instrument operating status, reagent storage conditions and exhaust system functionality. Monthly comprehensive safety drills are organized, covering chemical leakage emergency response, fire hazard handling and cryogenic material accident disposal, to ensure all staff fully master emergency response protocols for potential laboratory risks.
3. Full-Chain Quality Control System & Product Advantages
Strict quality control runs through the entire industrial chain starting from raw material procurement to finished product cross-border delivery. We implement a three-level batch inspection mechanism: incoming raw material verification, semi-finished intermediate sampling testing and full-comprehensive finished product analysis. No production batch can enter packaging and shipment procedures until all testing indicators meet our internal enterprise standards, which exceed average international specifications for lab research supplies.
For every batch of lyophilized research peptides such as HX5 5mg vial products, we provide an independent complete Certificate of Analysis (COA) containing LC-MS mass spectrum identity records, HPLC purity chromatograms, residual solvent test data, heavy metal content reports and endotoxin detection results, delivering fully traceable technical documentation to support customers’ laboratory experimental data recording and academic research publication.
All finished lab research materials are manufactured via sterile vacuum freeze-drying technology and sealed inside neutral borosilicate glass vials under dust-free ISO 7 cleanroom conditions. Each product label clearly displays product name, net content, unique batch number, manufacturing date, recommended storage conditions and prominent “Research Use Only” reminder. Global cross-border shipments adopt insulated cold-chain packaging with temperature-stabilizing phase-change materials to avoid temperature fluctuations damaging sample structural integrity during long-distance transit.
