Model SL-3 Stainless steel sealed liquid spectrophotometer cell ensures
accurate visual alignment of the cell components. These cells never have
partially blocked filling ports and they never leak. The SL-3 is
assembled by placing the front plate face down and then placing the front
lead gasket with holes in alignment with the luer
lock syringe filing ports. The front drilled window is then placed in
position over the ports which are still visible. The mercury amalgamated
spacer, rear window, neoprene gasket and back plate can then be
positioned without difficulty to seal the cell. All steel plates used in
the cell are lapped optically flat to ensure a perfect amalgam seal and
accurate alignment. This is the reverse of most spectrophotometer cell
designs, which do not insure accurate alignment. Configuration of one of
the filling ports on the edge of the front plate facilitates proper
filling and emptying of the cell and prevents liquid sample material from
damaging the windows and also prevents breaking the amalgam seal.
Model SL-3 cell will fit all dispersive and FTIR spectrophotometers. The
aperture of the dispersive cell is 22.5mm x 10mm and the aperture of the
FTIR cell is 16mm. The window size for both the dispersive and FTIR cell
is 38.5mm x 19.5mm x 4mm. Available nominal pathlengths
are 1mm, 0.5mm, 0.2mm, 0.1mm, 0.05mm, 0.025mm and 0.015mm. Other pathlengths can be ordered. Pathlengths
can be nominal or calibrated to 4 decimal places (eg.
1.0152mm) and cell pathlengths can be matched
within ±3% for interchangability. ICL
also offers an infrared cell reconditioning service and a calibration
service for all spectrophotometer cells.
A calibration charge of $16.00 is automatically added to
the price of each cell, unless the customer expressly specifies that
calibration is not required. Pathlengths for
cells that are not calibrated are nominal and ICL assumes no
responsibility for the customer's inability to calibrate the cell or
for the failure of an uncalibrated cell to exhibit satisfactory
Model SL-3 cell is now available with pathlengths
of 2.5 micron, 5 micron, 7.5 micron and 10 micron. Please call or click here for pricing and additional information.
Part 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.
