Introducing the Mark 22 Trade-in Program

Introducing the Mark 22 Trade-in Program

Since its introduction in 1986, the Martek Mark 22 Calibrator has been the Quality Control Standard for validating and calibrating both conductivity and pH meters for ultrapure water applications.

Many of our customers have used their Mark 22s for many years, even decades. And since we can repair all of our equipment, they have been able to get the most out of their original purchase.

Now, we are offering a trade-in program to help our customers turn in their old, tired Mark 22s for new ones.

Based on the age and condition of your Mark 22, you can receive credit towards the purchase of a new one. Below is the schedule:

 0-5 years old receive a $750-$1,000 credit
 6-10 years old receive a $500 credit
>10 years old receive a $250 credit

Simply return your Mark 22 to Martek with a note requesting a credit. We will evaluate each one to determine its age and condition and then inform you of your credit. It’s that simple.

So, turn your gold-colored Mark 22s into actual gold and get your credit towards a new one today!
