We offer Waters pump control modules, often abbreviated PCM. Truthfully there is virtually no rebuilding taking place with these PCMs. They are ultra low maintenance and as they do not even have cooling fans, we cannot even change the fan filter media as we can in almost every other Waters item. At their worst the rubber will require changing and the covers will need painting.

Relative to other items such as a refractive index detector, the testing is also limited. We simply ensure that they can drive pumps within specification and can maintain the load for some time.

Due to their simplicity and reliability there is not a great difference in the price of a PCM with our 90 day warranty or with our standard 2 year warranty. As a result we quote a two year warranty only.

Unlike most of the other items we have to sell there really isn't much to say about these units!

At one point all of our prices were posted online. Since the subprime fiasco of 2007 we have had an increasingly difficult time keeping our online prices up to date with the number of currencies that we normally quote in. Worse yet (for us) the prices of many instruments are in a state of flux. At this time(June 2010) we are in a buyer's market, this is an excellent time to buy used instrumentation, with prices approximately 10-15% lower then in 2007. Unfortunately we have had to switch from an online pricing setup to a quote-on-request one.

If you have any questions at all please don't hesitate to contact us. Our sales people will never "follow up" with you afterwards and if you contact us by email we will never add you to our spam list. We do not and will not, ever have one.

If you could please send an email to info@2h2inc.com we should be able to provide a quote to you within a few hours or please visit our contact page for our telephone number and mailing address
