Types of Glass Reactors
Benchtop Reactors
Benchtop reactors are designed for small-scale experiments, typically ranging from 500 mL to 5 L. Their compact size makes them suitable for placement under fume hoods, facilitating safe handling of volatile chemicals. These reactors are commonly used for chemical synthesis, testing reaction variables, and conducting preliminary experiments before scaling up.
Pilot Scale Reactors
Pilot scale reactors range from 10 L to 150 L and are essential for scaling up processes from benchtop experiments to larger production volumes. These reactors allow researchers to optimize conditions for pharmaceutical production, chemical synthesis, and other applications where larger quantities are required. They provide a controlled environment to assess the feasibility of scaling a reaction.
Jacketed Reactors
Jacketed reactors come equipped with an additional layer of glass surrounding the main vessel, allowing precise temperature control. This feature is crucial for temperature-sensitive reactions, such as those found in chemical synthesis and distillation processes. The jacket can be connected to a cooling or heating system, ensuring that the reaction mixture remains at the desired temperature throughout the process.
Filter Reactors
Filter reactors are designed to integrate filtration directly into the reaction process. Typically available in sizes from 500 mL to 100 L, these reactors feature a built-in filter plate at the bottom, enabling the immediate separation of solids from the liquid phase after the reaction. This design streamlines the process, reducing the need for additional filtration equipment.
Lifting Reactors
Lifting reactors, ranging from 10 L to 150 L, are designed for ease of use, featuring an electric lifting mechanism that allows the lid to be raised without removing ancillary equipment. This accessibility simplifies loading, cleaning, and maintenance, making it particularly beneficial in laboratory settings where efficiency is paramount.
Explosion Proof Reactors
When working with volatile substances, explosion-proof reactors are essential. These reactors adhere to strict safety standards and are equipped with UL-rated components, making them suitable for use in environments where flammable vapors are present. They often include features designed to contain any potential hazards, ensuring the safety of laboratory personnel.
