Ordering Online with Rainhart Testing Equipment

Thank you for visiting the Rainhart Test Equipment website; we have designed the site to be easy to use.

There are two ways to place orders with us via our online store, you will be asked at checkout which option you wish to utilize:

  1. If you are an existing Rainhart Testing Equipment or an HMA Lab Supply /  InstroTek customer you may charge items on Net 30 terms.
  2. Credit Card.

If you are NOT an existing client setup on Net 30 terms you may complete an Rainhart Test Equipment Credit Application here .

Customer Profile Account

You may register a Customer Profile Account with our website here. This will allow you to view your order history and specify and save multiple delivery/billing address locations. You may also receive special offers and discounts periodically. This is not a requirement, unless you are a tax exempt client.

Tax Exempt Clients

If you are a tax exempt client or entity, we will require you to create a Customer Profile Account on our website here.  When you have created a Customer Profile Account, and once we have a copy of your Tax Exempt form on file, we can alter the tax settings to allow you to check out without tax being assessed on your order.

You Can Always Call Us

We appreciate that some clients prefer not to order online, you are always welcome to call us at (512) 452-8848  to speak with a member of our team. You are also welcome to e-mail us at
