However, when faced with different brands and specifications, how to choose a device that is both safe and efficient? This article will provide you with professional purchasing strategies from four dimensions: glass material, structural design, sealing performance, and safety protection.

Do you want to achieve efficient and safe chemical reaction control in the laboratory? 

Double layered glass reactor is definitely your best choice! Multiple capacity options from 1L to 200L to meet different experimental needs. This article will delve into the functional characteristics of a double-layer glass reactor, helping you better understand and use this laboratory artifact.

A double-layer chemical glass reactor is a precision equipment used in laboratories, mainly for conducting various chemical reactions. Its double-layer structure design not only effectively isolates heat, but also provides a visual observation window, making the experimental process clear at a glance.
Double layered glass reactors are typically equipped with stirring devices, temperature control systems, and vacuum systems, making them an ideal choice for experimental operations such as chemical reactions, synthesis, and distillation. Whether it's teaching demonstrations or research projects, its presence can be seen.

How to select your double-layer chemical glass reactor?

1、 Glass material: High borosilicate is the bottom line
The glass material of the reaction vessel directly determines its heat shock resistance and compressive strength. Be sure to confirm that the equipment uses 3.3 high borosilicate glass. This material has an extremely low coefficient of thermal expansion (3.3 × 10 ⁻⁶/K) and can withstand drastic temperature changes (such as rising directly from -60 ℃ to 200 ℃ without breaking). For reactions involving strong acids and bases, it is recommended to choose glass components that have undergone heat tempering treatment to enhance their resistance to mechanical impact.
2、 Structural Design and Mixing System
Mezzanine design: The double-layer glass structure is used to connect the circulating bath (heating or cooling). Attention should be paid to the interface size (usually DN15 or DN25) and pressure resistance of the interlayer. High quality equipment is usually designed with splash guards to prevent circulating liquid from splashing.
Mixing system: Mixing is the key to mass transfer. For high viscosity materials, it is recommended to choose anchor or frame type mixing impellers; For low viscosity homogeneous reactions, propulsion or turbocharging are more efficient. Meanwhile, it is confirmed that the mixing shaft adopts PTFE mechanical seal or magnetic coupling drive, which can effectively eliminate the risk of leakage in high-pressure reactions.
3、 Sealing and Interface Standards
The sealing performance of the reaction kettle directly affects the maintenance of vacuum degree and solvent recovery rate.
Sealing material: PTFE (polytetrafluoroethylene) coated rubber gasket is preferred, with much better corrosion resistance than ordinary nitrile rubber.
Interface standard: Confirm whether the interfaces on the kettle cover (such as temperature measurement port, feeding port, condensation reflux port) comply with standard grinding ports (such as 24/29 or 29/32) or flange connections, in order to facilitate quick assembly with other glass instruments (such as constant pressure drip funnels, condensers).
4、 Security Protection and Compliance
Explosion proof requirements: If the experiment involves flammable and explosive solvents, explosion-proof motors and electrostatic grounding devices must be selected.
Protective cover: For large capacity (>10L) reactors, it is recommended to choose a transparent PC protective cover to prevent accidental glass breakage and injury.
Certification: Check whether the equipment has passed CE certification and ISO quality management system certification.
