    After you buy, you shouldn’t have to wait weeks for your gear to arrive. We ship fast so you can keep your cleanroom project on schedule.

    We service everything we sell. That means you get faster troubleshooting support and better response times than you would with other manufacturers or manufacturer’s reps.

    Special pricing is available for your business. Contact us and set up an account to make sure you get the best price available on every purchase.

    We guarantee you’ll get the right instrument for your cleanroom. If it isn’t exactly right, we’ll swap it out and find the right choice.
