Material Pros Cons
Acrylic
(Common tradename: Plexiglas®)plexiglas
  • Clear, lightweight
  • Strong, rigid
  • Inexpensive
  • Avoid in aseptic applications: Damaged by alcohol and other cleaning agents
  • Dangerous for ESD-sensitive parts: Generates surface charges
  • Hard to clean: surface charges cling to particles
Static-Dissipative PVC

See the difference!
  • Clean and ESD-Safe: dissipative surface charges to ground to prevent ESD and particle attraction
  • Easy to sterilize: Resists alcohol and other cleaning agents
  • Nearly transparent: full product visibility
  • Higher cost than acrylic
  • Not recommended for temperatures ≥120°F (49°C)
Non-Dissipative PVC
  • Easy to sterilize: Resists alcohol and other cleaning agents
  • Nearly transparent: full product visibility
  • Not recommended for temperatures ≥120°F (49°C)
  • Select static-dissipative PVC for ESD-sensitive operations
Polypropylene
  • Excellent chemical compatibility, particularly to acids
  • Strength
  • Opaque (white) surfaces; requires viewing windows
  • Generates surface charges
Polycarbonate
(Common tradename: Lexan®)
  • Broad chemical compatibility
  • Strong and rigid
  • Thermal resistance to 135°F (57°C)
  • Generates surface charges
Tempered Glass

  • Visual clarity
  • Weight
  • Susceptibility to breakage
304/316 Stainless Steel
  • Strength, durability
  • Resists solvents and strong cleaning agents
