| Notes
SILVAC offers the excellent temperature
resistance of silicone in a vacuum-rated hose (29.9
in./Hg at 70°F). The hose construction allows strong
vacuum at elevated temperatures; sample testing is
recommended.
The construction consists of
mandrel-wrapped layers of polyester-reinforced silicone
elastomer incorporated around a spiral wound stainless steel reinforcing
wire. The wire construction makes SILVAC crush and kink
resistant yet quite flexible.
SILVAC is a platinum-cured product, thus reducing extractables.
SILVAC is not recommended for implantable or in-body uses or for continuous steam applications.
SILVAC may be low pressure steam
sterilized in-line or autoclaved up to 250°F in a normal
autoclaving cycle. Its smooth bore and the ability to not
allow material to stick to the tube wall facilitates easy
cleaning and system purging. If exposed to repeated steam
sterilization or long-term high temperature or pressure,
silicone will eventually relax and become gummy. It
should then tbe replaced.
Care is recommended in the selection
and application of fittings and clamps for SILVAC as
sharp barbed fittings or unlined metal clamps could tear
into the wall and possibly cause a failure.
Each length is individually packaged in a heat-sealed polybag and should be sterilized prior to use.
