Proteus® LSG HDPE

High Density Polyethylene

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.

Intended Use

Proteus® LSG HDPE is only intended for applications in which the duration of contact with human body tissue is limited to less than 24 hours, or wetted contact applications in bioprocessing.

Furthermore, LSG materials are not intended for use in the manufacture of medical devices that will be permanently implanted in the body, nor are they intended for use in life-sustaining medical devices.
