Precision Engineering for Uncompromised Analytical Integrity

CHANCE INC. (Zhenjiang CHANCE Laboratory Technologies Inc. / Brand: CHANCEPRO) is an advanced manufacturer and international supplier specializing in precision chromatography consumables, trace-analysis vessels, and laboratory filtration solutions.

Headquartered in Jiangsu, China, CHANCE INC. bridges advanced material science and high-precision thermal forming to engineer critical analytical consumables. We serve pharmaceutical QC laboratories, contract research organizations (CROs/CDMOs), environmental testing authorities, and global OEM partners across Europe, North America, Japan, and Southeast Asia.

What We Do: Technical Focus & Product Portfolio

Modern analytical instrumentation—such as UHPLC, GC-MS/MS, and ICP-MS—demands stringent baseline cleanliness, minimal bleed, and exact dimensional reproducibility. CHANCEPRO consumables are engineered to eliminate ghost peaks, surface adsorption, and mechanical needle jams.

1. Chromatography & Autosampler Consumables

Autosampler Vials & Micro-Inserts: Comprehensive range including 2 mL standard screw-thread (GPI 8-425, 9mm short-thread), crimp-top, and snap-top vials, as well as 10 mL/20 mL headspace vials and EPA/VOA/TOC storage vials. Precision-drawn from USP Type I, Class A neutral borosilicate glass with controlled neck concentricity and uniform wall thickness.

Closures & Ultra-Low-Bleed Septa: Bonded and pre-slit cap-septa systems utilizing high-purity, medical-grade PTFE/Silicone formulations. Designed for optimal resealability, reduced coring, and negligible chemical background.

Surface Deactivation & Silanization: Proprietary vapor-phase and liquid silanization protocols that neutralize active silanol groups ("Si-OH" ), delivering near-zero surface adsorption for highly polar analytes, active pharmaceutical ingredients (APIs), trace pesticides, and proteins.

2. Inorganic Trace & Digestion Vessels

TFM / Modified PTFE Digestion Liners: High-pressure digestion inner vessels and inserts compatible with major microwave digestion platforms. Machined from high-purity modified PTFE (TFM) for superior thermal-pressure resistance and structural integrity.

Acid-Steam Cleaned & Validated: Optimized surface finish allowing rigorous sub-boiling acid cleaning routines to guarantee ultra-low elemental blank values required for ppt/ppq-level ICP-MS analysis.

3. Separation & Sample Preparation Essentials

Complete lineups of certified syringe filters (PES, PTFE, PVDF, Nylon, MCE), centrifuge ware, and specialized sampling consumables engineered to protect high-end analytical columns from particulate fouling.

Manufacturing Rigor & Quality Architecture

At CHANCE INC., process capability is treated as a core specification. Our manufacturing operations combine cleanroom manufacturing environments with automated visual inspection and continuous Statistical Process Control (SPC).

• Thermal Stress & Surface Chemistry Control: Precise hot-forming parameter modulation and stabilized annealing cycles prevent thermal stress concentrations and suppress surface alkali phase separation (post-forming bloom), preserving neutral borosilicate inertness.

• Instrument Compatibility Guarantee: Strict compliance with international thread standards (e.g., GPI finish standards) ensures seamless compatibility with leading autosamplers, including Agilent, Thermo Fisher Scientific, Shimadzu, Waters, and PerkinElmer.

• Closed-Loop CAPA & Full Traceability: Governed by an active Corrective and Preventive Action (CAPA) framework. Every commercial batch is supplied with an authentic Certificate of Analysis (COA), linking raw tubing melt composition, dimensional inspection logs, and extractable screening data back to specific production lots.

Global Distribution & OEM/ODM Partnerships

CHANCE INC. operates an agile, export-oriented supply chain built to support diverse international trade terms and multi-tier distribution networks.

• OEM / Private Labeling: Turnkey custom branding, specialized cleanroom packaging, custom kit assemblies, and dedicated dimensional toolings for international brand owners.

• Flexible Logistics Infrastructure: Experienced execution across EXW, FOB, CIF, and DDP terms, with streamlined documentation workflows (full COA packages, Certificates of Origin, and regulatory conformity filings).

• Technical Collaborative R&D: Direct engineering-level dialogue to co-develop custom micro-sampling inserts, specialized deactivation grades, or tailored liner geometries for unique analytical workflows.
