Chemical Information
The tubing inside the manifold body is polyimide (nylon) coated with
PTFE. Additional connection tubing is silicone. The removable tips include
a medical-grade polypropylene Luer-lock fitting with a fused silica
(quartz) needle coated with polyimide outside and PTFE inside. These
materials are resistant to most acids, bases and organic solvents. To avoid
dust contamination, we recommend pre-rinsing the Perfusion Pencil and
tip with distilled water. Also, it is good practice to discard the first few
microliters of solution before using the device. The Heated Perfusion
Pencil and removable tips are shipped non-sterile. The Pencil can be
chemically sterilized with cleaning solutions in each line. The removable
tips can be chemically sterilized or autoclaved. However, repeated
autoclaving may weaken the adhesive bond between the luer-lock fitting
and the needle.
