2. Standardized R&D & QC Laboratory Environment & Supporting Facilities
2.1 Scientific Partitioned Laboratory Layout
TanHong operates a self-owned integrated laboratory complex covering over 3,800 square meters. The space is scientifically divided into physically isolated independent functional zones to completely eliminate cross-contamination risks between different experimental procedures:
- Synthetic Preparation Laboratory: Equipped with independent fume hood stations for peptide coupling, chain assembly and target compound cleavage reactions; separate operation positions are assigned for different batches of experimental samples to avoid cross mixing.
- Chromatography Purification Zone: Specialized area fitted with analytical and preparative HPLC systems for target component separation, gradient elution and high-purity enrichment of synthetic products.
- ISO 7 Dust-Free Lyophilization Clean Workshop: Constant-temperature low-particle clean area for vacuum freeze-drying of peptide powder, sterile split filling and airtight vial sealing of finished research samples.
- Central Quality Control Testing Lab: Unified testing space responsible for batch identity confirmation, purity quantification, residual component screening, heavy metal limit inspection and microbial indicator detection.
- Multi-Gradient Constant-Temperature Sample Storage Room: Temperature-controlled layered storage space for raw material inventory, finished lyophilized reagents and batch retention test samples.
- Classified Experimental Waste Disposal Chamber: Independent closed area for sorting, neutralizing and temporary standardized storage of liquid and solid laboratory waste before delivery to certified professional disposal organizations.
- Technical Document & Sample Archive Room: Constant-humidity dry storage space to permanently preserve batch test reports, full experimental operation records, retention samples and formal technical files to realize full batch traceability.
All functional zones are equipped with separated personnel access channels and independent air circulation systems. All staff must pass dual-stage air shower purification before entering core dust-free processing zones. Workflows for raw material handling, finished product packaging and waste disposal are strictly separated to prevent cross-contamination between different compound varieties and production batches.
2.2 24-Hour Intelligent Constant Environmental Control System
Each laboratory functional zone is equipped with uninterrupted intelligent environmental monitoring networks with real-time data recording and automatic early warning functions. Core environmental indicators are precisely stabilized to prevent structural degradation of temperature-sensitive freeze-dried peptide samples during synthesis, purification and storage:
- Constant Temperature Control: The entire laboratory complex maintains a stable temperature range of 20–24°C; the ISO 7 lyophilization clean workshop supports fine adjustment within ±0.5°C to avoid thermal damage to fragile peptide solids.
- Humidity Stabilization: Integrated automatic dehumidification and humidification equipment locks relative humidity at 40%–55% all year round, effectively preventing powder agglomeration, static interference and moisture-induced structural damage of lyophilized solid reagents.
- Air Purification & Positive Pressure Management: Multi-layer HEPA high-efficiency air filtration equipment is installed inside ISO 7 clean zones to maintain stable positive pressure of 5–10 Pa, 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 discharge.
- Full-Cycle Real-Time Monitoring Sensors: Wireless sensors are laid throughout all lab areas to track temperature, humidity, airborne particle concentration, pressure difference and exhaust gas levels 24 hours a day. All environmental operation data is automatically stored on the laboratory cloud server for at least 7 years, forming traceable environmental archives for every single production and testing batch. The system will immediately send graded alarm reminders to on-site supervisors and remote management terminals once any index exceeds standard thresholds for rapid intervention.
All lab spaces adopt seamless anti-corrosion epoxy wall coatings and non-porous stain-resistant vinyl flooring, which can be quickly wiped and disinfected daily without residual chemical stains. All experiment countertops use imported acid-resistant polypropylene panels, resistant to common organic solvents and acid-base reagents, simplifying daily sanitation maintenance and extending service life.
2.3 Complete Precision Laboratory Instrument Configuration
We deploy a full set of internationally recognized precision synthetic and analytical instruments to complete 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 lyophilization 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 enforced 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 implemented: 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, gas cylinder placement 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 FN1 1mg 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 lyophilization 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.
