Glass-Lined Reactors

IMG_2508

De Dietrich glass-lined reactors are robustly designed and manufactured to stand up to very harsh environments.  Glass-lined steel provides you with the best of both materials; fusing glass to steel produces a composite material with an inside that offers a nearly universal corrosion protection and an outside that provides structural strength and durability.   

Glass-lined reactors are either custom fabricated or built to industry standards. The models available include:

Features

  • Volumes from 1 to 20,000 gallons
  • Pressures from full vacuum to 450 psig
  • Temperatures from -20ºF (-30ºC) to 500 ºF (260ºC)
  • Ability to add or remove heat to the batch
  • Variety of accessories and instrumentation (OptiMix, GlasLock, etc.) are available to further enhance the performance of your vessel

 

Advantages

  • Superior corrosion resistance to acids, bases, water and other chemical solutions.
  • Chemical, mechanical and thermal properties offer a diverse range of operating conditions.
  • Top quality construction with thicker steel than other brands, creating flatter flanges and less distortion.
  • Cost-efficient solution when compared to lifespan of steel and alloy vessels, whose service life can be drastically shortened due to their inability to resist corrosion the way glass lining can.
  • Adapted to cGMP requirements for cleaning, cleanliness, and sterilization.

Borosilicate Glass Reactors

QVF glass reactor

De Dietrich Process Systems offers a broad range of solid glass reactors manufactured from QVF borosilicate glass, providing excellent resistance to chemical attack and corrosion as well as transparency for optimum visual observation. Our QVF glass reactors meet a wide variety of process applications and volume requirements ranging from laboratory scale and pilot plants to full scale production units. They are a popular choice in research and development as well as kilo plant production applications throughout the chemical, biotech, and pharmaceutical industries.

Many standard sizes and designs are kept in stock for quick delivery. Our diverse product line includes the standard “Q-Series” units, OptiMix wall-mounted baffle reactors, as well as custom units, with various accessories and instrumentation to provide the optimum solution for your application.

Features

  • Available in a variety of shapes including spherical, cylindrical, and graduated cylindrical
  • Volumes from 5 to 100 liters (stock standards 30, 50 & 100 liters)
  • Pressures from full vacuum to 8 psig (0.6 bar)
  • Temperatures from -60°F (-50ºC) to 250°F (120°C) (higher temperature available, to 390°F/200°C)
  • Dissipative Sectrans glass coating available for external protection

 

Advantages

  • Process visibility
  • Superior corrosion resistance
  • Anti-adhesive and nonporous surface resists the buildup of viscous or sticky products
  • Can handle a variety of functions
  • Compatible with other highly corrosion resistant materials such as PTFE, SiC and Glass-Lined Steel

Combination Glass / Glass-Lined Reactors

VERI-Reactormaxh=398,maxw=250,h=657,w=412

The VERI reactor series is a glass-lined steel reactor body with a solid borosilicate glass cover. The combination glass/glass-lined design was developed from the pharmaceutical industry's demand for maximum purity and optimized heat and mass transfer combined with suitability for GMP use. Our combination reactor model is widely used in pilot plant units due to its robust design.

The VERI reactor is specially designed for the two process stages of reaction and distillation. The reaction stage operates under total reflux, allowing the solvent to be distilled off as effectively as possible in the concentration phase. The vessel was designed for a compact layout with reduced headroom requirements, suiting the limited availability of space in the majority of laboratories.

Features

  • Volumes from 16 to 100 liters  
  • Pressures from full vacuum to 9 psig (0.6 bar) (high pressure versions also available)
  • Temperatures from -76°F (-60°C) to 400°F (200°C)
  • Available options include:
    • Hydraulic lifting device for the reaction vessel
    • Phase separator
    • Electronic speed indicator
    • OptiMix wall-mounted baffles
    • Weighing cells for reactor, feed and distillate vessel
    • Process control engineering
    • Other accessories and instrumentation

 

Benefits

  • Combined glass/glass-lined construction offers the strength of glass-lined steel with the visibility benefit of borosilicate glass.
  • Modular construction can be expanded to handle various special functions. 
  • Can accommodate space constraints
