ACCURACY CHECK
To verify instrument performance, an accuracy check should be performed at regular intervals using the
K-8000 TTi
®
Colorimeter Series Accuracy Check Kit (available as an optional accessory). The kit contains
five secondary absorbance standards. An accuracy check is performed using the Absorbance test, located in
the ALL TESTS menu. The absorbance of each secondary standard is measured at specified wavelengths
and the measured absorbance must fall within specific tolerances (provided with the kit) to verify instrument
performance.
ROUTINE CARE
Do not use chemicals, solvents, or abrasives to clean or dry any part of the instrument. Clean and dry the
enclosure, display, sample cell compartment, and sample cells after use or when needed as follows:
• Enclosure – Use a soft, nonabrasive cloth and water or mild detergent.
• Display – Be careful not to scratch the display. Use a soft, nonabrasive cloth or lens tissue and water or
mild detergent.
• Sample Cell Compartment – Be careful not to scratch the sample cell compartment. Use the foam brush
(supplied); a soft, nonabrasive cloth or lens tissue; and water or mild detergent.
• Sample Cells – Be careful not to scratch the sample cells. Use the foam brush (supplied) or a soft,
nonabrasive cloth and water or mild detergent. Rinse thoroughly with deionized or distilled water.
WASTE DISPOSAL
As a chemical manufacturer, Taylor Technologies is required to prepare a Safety Data Sheet (SDS) for every
reagent we produce. The Hazard Communication Standard promulgated by the U.S. Department of Labor’s
Occupational & Safety Health Administration (OSHA) specifies what information must be included in an
SDS to provide workers and emergency personnel with procedures for handling the chemical in a safe manner,
including disposal considerations. You may request an SDS for each of the reagents in your purchase at the
time the order is placed. SDSs may also be printed from our corporate website, www.taylortechnologies.com.
They can be found under the Product Info button; from the drop-down menu, select “Documents” then “SDSs.”
Please note that, beyond adding any new information within three months of awareness of a change affecting
the content of a Safety Data Sheet, there currently is no specified time required by OSHA between revisions
and/or updates to SDSs.

(WHMIS) compliance. Contact them directly, as follows:

It is the user’s responsibility to abide by any local and state/provincial waste disposal requirements that supersede
federal guidelines. Consult with a regulatory agency in your area to be certain you are in compliance with
prevailing hazardous waste disposal guidelines. This Environmental Protection Agency website link may be
