cell consists of two (2) windows separated by a lead spacer
that is amalgamated to the windows with mercury. The mercury
lead amalgam is impervious to solvents and to virtually
any sample. The spacer and windows form a sealed liquid
sample compartment. In the case of the SL-2 configuration,
the sandwich cell is also amalgamated to an aluminum front
plate containing luer-lok syringe filling ports.
cells can be used to recondition sealed cells, to have backup
or supplemental sealed cells of different pathlengths, or
in a demountable cell. You will find sandwich cells that
will fit most sealed and demountable cell holders that have
been made in the last 25 years. The SL-3 configuration uses
38.5 x 19.5 x 4mm rectangular windows, the Beckman-Specac
configuration uses 41 x 23 x 6mm rectangular windows and
the SL-2 & Spectra-Tech configuration uses 32 x 3mm
discs. These sandwich cells can be used with any sealed
or demountable cell mount with the same window sizes, regardless
of who may have manufactured the cell in the mount. They
are compatible with Barnes, Beckman, Buck, Mc Carthy, Perkin-Elmer,
Pike, Spectra-Tech, Specac, Wilks and Wilmad cells and mounts.
in Fig. 1 below, the SL-2 sandwich cell replaces the Luer
syringe plate, the lead gasket, both crystals and the lead
spacer. The SL-3 configuration of the sandwich cell replaces
both windows and the lead spacer as shown in Fig. 2 below.
numbers which end with the letter "W" are
nominal part numbers only and are used online simply
to identify the cell type and window material. Part
numbers which end in "W" do not denote a
specific path length. We will assign the correct part
number when you place your order. If you want confirmation
of the correct part number please request it when
you call in your order or request an on-line e-mail
confirmation of the correct number.
