Frequently asked questions – stainless steel reactors

What’s the difference between 304 and 316L stainless steel reactors?

316L contains molybdenum for better acid resistance and is preferred in pharma and food-grade systems.

Are stainless steel reactors good for pharma applications?

Yes. Many reactors in IPP’s inventory are previously used in GMP settings and feature smooth internal finishes.

Can I get a jacketed and agitated stainless steel reactor?

Absolutely. IPP stocks hundreds of jacketed, agitated stainless steel vessels in various sizes and pressure ratings.
