Bilayer
Cuvettes
Cuvettes,
made from either polystyrene, polysulfone or Delrin,
have a 0.5 mm well milled into their base to confine
the motion of stirbars and to reduce mechanical noise
artifacts. A 2 x 5 mm or 2 x 7 mm Teflon-coated
stirbar is supplied with each 13 mm or 22 mm cup,
respectively. Standard available aperture diameters
are 150, 200 or 250 µm. Custom aperture sizes are
available. The wall thickness at the aperture is 250
µm (0.010").
Cuvette
Material
Polystyrene
has been a favored material for cuvettes for several
years. However, its poor resistance to organic
solvents can lead to degradation of the aperture.
Cuvettes have also been made from Delrin (acetyl
resin) and many users report good bilayer formation as
well as easier maintenance and longer life. It should
be noted, however, that the Delrin cuvettes do not
work equally well in all applications and with all
users.
Warner Instruments also offers cuvettes made from
polysulfone. This material has many of the mechanical
properties of polystyrene (rigidity, machinability,
optical transparency) coupled with an increased
chemical resistance to solvents. The choice of cuvette
material will depend on your application.
