Proteus® & Sanalite® Family

Proteus® & Sanalite® are a family of polyethylene and polypropylene shapes that exhibit a high strength-to-weight ratio, excellent chemical resistance, low moisture absorption, and high performance in thermoforming and corrosive environments. These versatile plastic materials are easy to fabricate and find use a wide variety of applications below 180°F (82°C).

Proteus® LSG HDPE
Proteus® LSG HDPE (Life Science Grade) stock shapes are made from HDPE resin and pre-assessed for biocompatibility on both resin and stock shape for up to 24 hours body contact according to USP VI and ISO 10993, as well as wetted contact in bioprocessing.

Proteus® LSG HDPE shapes exhibit low extractables and leaching, low moisture absorption, and great resistance to chemical cleaning agents, allowing parts to retain excellent impact resistance and good tensile strength throughout repeated use. For these reasons, Proteus® LSG HDPE is a great candidate for upstream applications in bioreactors and downstream applications chromatography and filtration.
Proteus® LSG HS PP-H
Proteus® LSG HS PP-H (Life Science Grade, Heat Stabilized) stock shapes are made from high purity polypropylene resin that has undergone additional filtration to remove the last remaining black particles, thus increasing purity. The material is pre-assessed for biocompatibility at the stock shape level for bioprocessing applications according to USP VI and ISO 10993 and is supported for use in non-body contacting medical applications.


Heat stabilized to provide improved dimensional stability and a higher heat deflection temperature compared with standard polypropylene grades, Proteus® LSG HS components can withstand repeated steam sterilization cycles and autoclaves and are highly resistant to cleaning agents, disinfectants, and various solvents. For these reasons, Proteus® LSG HS is a strong candidate for medical non-body contact applications such as surgical trays, caddies, and device housing components.
Proteus® LSG HP PP-H
Proteus® LSG HP PP-H (Life Science Grade) stock shapes are made from high purity polypropylene resin that has undergone additional filtration to remove black particles, thus increasing purity. The material is also pre-assessed for biocompatibility at the stock shape level for wetted contact applications in bioprocessing according to USP VI and ISO 10993.


Proteus® LSG HP PP-H shapes are characterized by their excellent resistance to chemical cleaning agents and zero moisture absorption. These traits, in combination with their low levels of extractables and leachables, make Proteus® LSG HP PP-H components a favored solution in the bioprocessing industry for upstream applications in bioreactors (e.g. valves, mixers, impellers), downstream applications in chromatography (e.g. fluid distribution plates), and filtration.
