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

pvc

See the difference!
  • Clean and ESD-Safe: dissipates 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)
Stainless Steel
  • Strength, durability
  • Resists most cleaning agents
  • Conductive surfaces minimize ESD danger
  • Electropolishing removes subsurface contaminants
  • Requires viewing windows
  • Cost
  • Damaged by acids
Polypropylene
  • Resistant to acids & other chemicals
  • Strength, durability
  • 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
