Keynote® Control Solution

I was relieved when the control solution matched perfectly with the meter’s expected range on my first try. The bottle’s cap seals tightly, so I don’t worry about spills in my kit. It’s a straightforward, no-fuss way to double-check my readings.

The bottle's nozzle dispenses exactly one drop at a time, making it easy to control. I used it to double-check my meter's accuracy and got consistent readings every time.

I appreciate that each vial comes with clearly printed lot numbers and expiration dates, making it easy to verify I'm using fresh solution. The liquid runs through the strip smoothly every time, and my readings have been consistently accurate.
