VERI-FRY®
PRO and FS Tests
GiTIC™ TUBES Four tests measure oil quality:
SP-830-LT
VF-CC
WAR-ANA-12
LAD-01
REF-WET
The Total Polar Materials test, for official use, requires that calibrating oil samples first be examined through column chromatography to determine the true polar value correlation with the VERI-FRY® PRO meter readings. A custom-made TPM calibration chart must be constructed for each specific operation to remove the effects of any chemically interfering materials. SYR-5
Filtering
is required for samples of oil contaminated with sugars and
phospholipids. Polypropylene syringes are 4" long and hold ~5ml
of oil. The polypropylene filters remove particles down to 5 microns
and offer simple, rapid filtering of heated liquid oils.

Each test is performed by introducing less than 5 grams of
oil into vials containing patented gels. The vials are supplied 50 to a
box with operating instructions. In the FFA
and (ppm) WET tests, a chart is supplied
that correlates the colorimeter's digital readout and the percentage of FFA and WET present
in the oil. Customers can choose to have a custom curve made for the TPM. The vials' box
(9.5"x4.5"x3.5") allows each vial to stand upright and
can be used for holding and storing the self-documenting completed
tests.
The VERI-FRY® PRO Spectrophotometer is a multi-wavelength colorimeter
that passes a beam of light through an inserted vial and converts the
absorbance units immediately into a digital readout of oil damage. The
value is compared to a chart for the test to determine actual
concentration. These meters give immediate readings with the press of a
button. A production spectrophotometer reads all
of the VERI-FRY®
and many other tests.
A plastic color comparator card is available
for the TPM test. Developed primarily for
the restaurant industry, it allows for some degree of accuracy in
determining oil quality, but lacks the precision of the digital
meters. Should customers wish to upgrade to meters to enhance their
quality control, the vials used with the TPM color card are also usable in the digital meters.
At their highest
precision use, the VERI-FRY® tests are somewhat sensitive to
temperature changes and the gel should be tested at 65°C ±2°C.
While any controlled heating method is acceptable, warmers are optional
but recommended devices that can hold up to 12 individual vials at the
ideal constant temperature. The vials stand upright and the number of
wells allow for an ultra-fast assembly-line testing technique. A
thermometer (not included), must be used to set the Warmer's operating
temperature. The TPM test,
used with the color card or meter, has only to be hot and clear, and
usually does not require temperature stabilization. 
The TKT Teflon®
ladle has been specially designed to take a sufficient sample amount for
a single test without damaging or contaminating a frying oil sample. Its
high resistance to heat transfer and 7" handle protect workers from
burns.
Reference
solutions for the FFA and WET tests are available to ensure that the colorimeter
maintains constant settings and reports consistent results. Each set
contains five bottles, each with sufficient oil solution for four tests.
Filtering is generally necessary for
testing used, abused or contaminated oils, to ensure maximum
reliability of PRO colorimeter readings.
