Scientific Vacuum Sales & Support, Inc. has everything you need to maintain, repair and enhance the capabilities of your vacuum system, including a wide variety of feedthroughs and viewports.
We carry the most common sizes of flanges with glass viewports. Our in-stock inventory includes:
- 1 1/3”
- 2 3/4″”
- 4 1/2″”
All in-stock viewports are available for immediate shipment. You may select the shipping carrier (UPS or FedEx) and shipping speed.
Custom Ordered Feedthroughs and Viewports
There are so many different sizes and configurations for feedthroughs that there is no “common” feedthrough options. There are also a number of sizes of viewports that are less frequently used, but we have access to them all.
We work with a number of suppliers, so we have hundreds of options for feedthroughs and viewports that can be ordered on-demand. Products are usually available in one to two weeks, depending on the backlog of the manufacturer.
If time is of the essence, please contact us. We will do everything we can to expedite shipping from the supplier to minimize delays in lab operations.
Vacuum Product Return Policy
Scientific Vacuum Sales & Support, Inc. offers a 30-day return policy on all vacuum products, including feedthroughs and viewports. However, to be returned, products must be unopened. To avoid the hassle of returns, please contact us before your order. We can help ensure you get the right products to meet your needs.
