Update September 21st, 2022 --

We are currently out of the original grey Smart Stir that is included in the TF-Pro and TF-Pro Salt. For this reason, the grey Smart Stir has been temporarily removed from individual sale. However, the Smart Stirs are currently on their way to us from California so we anticipate shipping to begin next week.

We now offer Taylor SpeedStir magnetic stirring devices as well as the Smart Stirs. The Taylor SpeedStir is a comparable device to the Smart Stir. It fits in the TF-Pro case where the Smart Stir would belong, works with all TFTestkits cylinders, and mixes tests automatically with the press of a button. 

If you prefer to receive a Taylor SpeedStir, select the corresponding option before adding a Pro kit to your cart and you will save $12 on your kit. Otherwise your Smart Stir will be shipped to you, free of charge, when it arrives.

We apologize for the inconvenience this has caused and appreciate your patience.

Blue Smart Stirs were ordered in error and are now on closeout sale. They are fully functional but there is one problem: the LED lights on the unit are tinted blue, which can interfere with testing visibility as opposed to helping. Hence, they are on steep discount! If you do not use the LED light function, they are no different from the original Smart Stir.
