A lot has happened since we began operation in 1951 and developed the beam-power Pentode tube, but at Penta Laboratories our core mission has remained unchanged: To provide a premium product and do our very best to assure customer satisfaction by delivering an exceptional level of service.
To this day we maintain an inventory of thousands of tubes and other parts for a variety of industries, including aerospace, manufacturing, medical, broadcast, scientific, military and high performance audio. And equally important is the fact that our Machlett Division is a world-leader in the food processing market with microwave ovens, parts, upgrades and service, as well as for other commercial applications where high power microwave energy is required.

We appreciate you taking this time to visit our website and invite to you contact us at your convenience should you have any questions about Penta Labs or our family of products, or if there anything we can do to help you in any way.

Once again, thank you for your support throughout these past decades … and best to you for growth and prosperity.
Sincerely,
Penta Laboratories
