Büchi stirring vessel

Product Description

The chemical-resistant glass cover carries the double-acting, dry-running, explosion-proof agitator shaft seal and the other superstructures, such as valve technology, hand hole, safety device and, if required, temperature sensor, pressure gauge.

The agitator shaft seal, which was developed in-house by Buchi, has been further developed and optimised over decades. It provides a double-acting seal on the agitator shaft using precisely matched sealing technology. This protects people and products from interaction.

The explosion-proof agitator shaft seal is driven by a suitably customised explosion-proof drive. The speed is variably adjustable via a handwheel. Both the agitator shaft and the agitator geometries (armature, propeller, impeller, etc.) are available in various materials.
Connections between two glass components are usually joined using the Buchi-Flex connection system. This guarantees a uniquely stress-free and flexible structure, which can also be installed by the hirer. The Buchi-Flex glass connection system is TA-Luft-compliant.

The components of the mixing vessels that come into contact with the product, regardless of whether they come into contact with liquids or gases, are metal-free as standard. The main materials that come into contact with your product (chemicals) are glass, PTFE and ECTFE. This makes them suitable for use in the pharmaceutical and electronics (semiconductor) industries.

Options and Accessories

• Coating: Glass components may be coated on the exterior for various reasons. One argument in favour of coating is protection against breakage and splintering.

• CIP nozzle: The CIP cleaning nozzle can be fitted to the cover plate via a quick-release coupling. The rotating head of the cleaning nozzle sprays the cleaning medium into the interior of the glass reactor at varying pressures.

• pH probe: Standard pH probes can be fitted into the MiniPilot via a pH probe holder, which protects the sensitive pH probe. Explosion-proof models are also available.

• Double-walled vessel: The glass vessels can be designed with single, double or triple walls. The triple-walled vessel is particularly well-suited for low-temperature applications due to its evacuated section.

• Insulation sleeves – are custom-made for individual glass components and protect the glass components from cooling down too quickly or maintain the temperature within the system.

• Triple-walled vessel: The glass vessels can be designed with single, double or triple walls. The triple-walled vessel is particularly well suited for low-temperature applications due to its evacuated zone.

• Measurement, control and regulation package: In addition to the standard measurement, control and regulation components, Buchi systems can be expanded with customised measurement, control and regulation packages.

• Filter funnel: Buchi filter funnels can be used to separate solids from the fluid after the reaction.

• Gas scrubber: The Buchi gas scrubber can be used to purify the exhaust gases produced during the reaction.
