Glass

Soda Lime Glass

  • Commonly known as flint glass
  • Resists attack from most common chemicals
  • Impermeable to oxygen and other gases
  • No permeation of container contents through glass wall

Amber Glass

  • Resists attack from most common chemicals
  • Impermeable to oxygen and other gases
  • No permeation of container contents through glass wall
  • Recommended for UV light-sensitive samples

Borosilicate Glass – 33 Expansion

  • Very high resistance against chemical attack
  • Meets requirements for USP Type I, Class A glass
  • Low coefficient of expansion gives high resistance to thermal shock
  • Low alkali content
  • Made without elements of calcium, magnesium, zinc groups, or heavy metals
  • Combined total of arsenic and antimony oxides is less than 0.005%

Borosilicate Glass – 51 Expansion

  • Very high resistance against chemical attack
  • Meets requirements for USP Type I, Class B glass

Plastic

High-density Polyethylene (HDPE)

  • Translucent
  • Flexible, but more rigid than low-density polyethylene
  • Highly resistant to non-oxidizing acids and aliphatic or aromatic hydrocarbons
  • Suitable for soil and sludge sampling

Low-density Polyethylene (LDPE)

  • Translucent
  • High impact resistance
  • Excellent resistance to weak or dilute acids, strong or concentrated acids, aliphatic alcohols, and bases

Polytetrafluoroethylene (PTFE)

  • PTFE is widely known as TEFLON®
  • Opaque
  • Maximum temperature use 250°C
  • Excellent resistance to weak acids, most strong acids, and bases
  • Very resistant to organic solvents
  • Can be autoclaved repeatedly

Polypropylene (PP)

  • Translucent
  • Rigid
  • Excellent stress-crack resistance
  • Effectively resists weak and concentrated acids, aliphatic alcohols, and bases
  • Can be autoclavable repeatedly

PET (Polyethylene terephthalate)

  • Glass-like clarity
  • Flexible
  • Less permeable to oxygen than polyethylene
  • Excellent resistance to dilute or weak acids, aliphatic acids, and aliphatic hydrocarbons

Polystyrene (PS)

  • Glass-like clarity
  • Rigid
  • Strong resistance to aqueous solutions
  • Limited resistance to organic solvents
  • Brittle at ambient temperature
  • May crack or break if dropped from bench-top height

Polyvinyl Chloride (PVC)

  • Transparent
  • Extremely good resistance to oils (except essential oils)
  • Very low permeability to most gases
