PEEK flow-cell

[a***@yahoo.it]

Hi,
my question is: whether a PEEK flow-cell has to be fabricated with
'usual'
machining techniques (like drilling, milling, cutting) or with rapid
prototyping (stereo lithography).
Thank you very much in advance,
Andrea

From the description, I would guess that conventional manufacturing
technology will be able to create as many as you want, once tooled up:

Fluorescence Flow Cell
With the FIA-SMA-FL Fluorescence Flow Cell, a fiber sends excitation energy
through a fused silica window into a 2-mm inner-diameter sample compartment.
Emitted energy is collected by a second fiber, oriented at 90?, that
connects to a spectrometer configured for fluorescence. Each unit includes
one PEEK flow cell, two optical windows, two stainless steel SMA 905
Connectors (which do not contact the fluids), four chemically resistant
tubing connectors, two meters of Teflon tubing, and six chemically resistant
seals. Two 600 ?m fibers (sold separately) are required.

For a "one off' design, contemporary machining will be far less
expensive than stereo lithography. If you intend to manufacture for
commercial purposes, then stereo lithography can be a winner over
conventional machining, depending on location (China vs. USA, Europe).
You have to examine the economic implications in detail.
