Why Choose Unionclay
Unionclay is an ISO 9001:2015 certified lab equipment manufacturer in Zhengzhou, exporting to more than 30 countries. Reactors leave our factory with G3.3 borosilicate glass and PTFE-Viton sealing as standard, whether you order a single 1L unit or a 100L pilot system — and OEM builds run on the same line. See the factory for yourself.
Premium Borosilicate Glass 3.3
All our reactors use G3.3 high borosilicate glass with excellent thermal and chemical resistance. Low thermal expansion ensures safety from -80C to 300C.
The same G3.3 vessels run across our glass reactor range from bench to pilot scale.Advanced PTFE Sealing Technology
Proprietary PTFE + Viton dual-seal system on all stirring assemblies. Zero-leak performance at vacuum levels down to -0.095 MPa.
The seal system ships standard on every jacketed glass and stainless steel reactor we build.Complete Product Ecosystem
Glass reactors, rotary evaporators, circulators, vacuum pumps – one supplier for your entire laboratory setup. Integrated system compatibility guaranteed.
Pair any reactor with a recirculating chiller, rotary evaporator and vacuum pump from the same catalog.Flexible Customization & OEM
Need explosion-proof configuration? Custom port arrangements? Special dimensions? We customize every reactor to your exact specifications. 9 sizes: 1L to 100L.
Custom configurations also cover fermentation tanks and TCU temperature control systems.Our Advantages
Scale-up is where equipment engineering shows: a process proven in a 1L SFS glass reactor has to behave the same way in the 100L model. We design all nine SFS sizes on one platform, machine critical components on our own CNC line in Zhengzhou, and provide technical support wherever the equipment ships.
Professional Laboratory Engineering
Designed for research laboratories, pilot-scale production, and industrial process development with stable performance and user-friendly operation.
High-Precision Manufacturing Process
Manufactured with advanced CNC machining and precision glass processing technology to ensure accurate assembly, smooth operation, and long service life.
Reliable Technical Support & Global Service
Our experienced engineering team provides professional pre-sales consultation, installation guidance, and long-term technical support for customers worldwide.
Applications
Pharmaceutical synthesis, chemical research, electronics processing, and university teaching labs each configure this equipment differently: a pharma suite pairs an SFS jacketed reactor with a DLSB recirculating chiller for temperature-critical steps, while a teaching lab runs 1L benchtop units. See the applications overview for reactor, evaporator, and chiller setups by industry.
