Continuous stirred tank reactor price manufacturers

The price is primarily driven by material of construction (MOC), vessel volume, and pressure ratings. Reactors made of 316L Stainless Steel or Hastelloy are significantly more expensive than standard 304 Stainless Steel due to superior corrosion resistance. Additionally, the jacket type (dimple, limpet, or full jacket) and the sealing mechanism (single vs. double mechanical seals) play a critical role in the final cost.

The motor power (kW) and impeller design (anchor, turbine, or propeller) are customized based on the fluid's viscosity. High-viscosity applications require high-torque gearboxes and explosion-proof (Ex-proof) motors, which increase the price. For pharmaceutical or food-grade applications, the surface finish (Ra < 0.4μm) and electropolishing requirements will further elevate the investment.

Buyers must ensure the equipment complies with international pressure vessel codes such as ASME Section VIII, PED (2014/68/EU), or GB150. For specific industries, look for GMP (Good Manufacturing Practice) compliance and CE marking. Requesting Material Test Reports (MTRs) and Hydrostatic Test Certificates is essential to validate safety and regulatory alignment.

Yes, many suppliers on Made-in-China.com offer modular CSTR systems or pilot-scale reactors (5L to 50L). While the unit price per liter is higher for smaller units, the lower total capital expenditure (CAPEX) and reduced chemical waste make them economically viable for R&D and specialty chemical production.

Always mandate a Third-Party Inspection (TPI) by agencies like SGS or TÜV before the final payment. Ensure the contract specifies Non-Destructive Testing (NDT), such as X-ray welding inspections and dye penetrant tests, to confirm structural integrity.

Focus on the Total Cost of Ownership (TCO) rather than just the sticker price. Negotiate for spare parts packages (seals, gaskets, bearings) to be included and request a performance guarantee linked to the final commissioning. Mentioning competitive quotes from other verified suppliers on Made-in-China.com can also provide leverage for volume discounts.

CSTRs are often oversized and fragile. Ensure the supplier uses seaworthy vacuum packaging and reinforced steel frames for shipping. For large units, clarify if the price is FOB (Free On Board) or CIF (Cost, Insurance, and Freight), and confirm the availability of Open Top Containers or Flat Rack shipping methods.

Utilize Secured Trading Services provided by Made-in-China.com to protect your funds. Use Letters of Credit (L/C) for large transactions to ensure payment is only released upon the presentation of valid shipping documents and inspection certificates.
