Refractive Index and
Mixing of Tri-Cool® TC-1
Refractive Index
A refractometer is used to determine the dilution ratio of Tri-Cool
TC-1. The refractometer takes light and bends it through the
solution to give a reading on the Brix scale. Below is a chart
that shows the refractive index vs. dilution ratio for Tri-Cool
TC-1(Fig. 2).
To obtain refractive index using a refractometer:
- Make sure prism and cover are clean. Clean with a soft
moist cloth and then dry thoroughly.
- Lift cover lid and place 2 drops of sample on the prism.
- Gently close cover - avoid air bubbles between prism and
cover.
- Look through the eyepiece and point the refractometer
toward any convenient light source.
- The scale and borderline should be visible (Fig. 1).
- Adjust the eyepiece for the sharpest image possible.
- Read the value at the point where the borderline crosses
the scale (Fig.1).
- Refer to graph for actual concentration level of Tri-Cool
TC-1 solution (Fig. 2).
- Clean prism and cover immediately after use.

Mixing
Tri-Cool TC-1 is a premium water based coolant. The following
steps are designed to optimize the mixing process and provide
a consistent dilutions and results. This can be best achieved
by adhering to the same mixing process.
Proper Mixing Procedures
Proper mixing procedures are critical to the attainment of long
coolant life and economical use of coolant concentration related
problems. Premixing coolant concentrate with pure water in accordance
with the coolant manufactures recommendations assures efficient
use of the concentrate.
- Pour one quart of Tri-Cool TC-1 into a measured container.
- Turn on a stream of water into a 5 gallon pail.
- Pour Tri-Cool TC-1 promptly into the stream of water and
finish the pour when 4 gallons of water are in the container.
- Finish filling pail to approximately 4 ½ gallons.
Mix with paddle, let sit one hour, mix again.
- Allow the foam to settle.
- Use a refractometer to measure the ratio and compare refractive
index to chart.
