Who We Are

We design and manufacture innovatively engineered accessories for scientific instruments.

Products & Services

Merlin Microseal

The Merlin Microseal for GC has two distinct sealing mechanisms that are never punctured. This eliminates septum coring and septum bleed and allows it to last up to 10 times longer than traditional rubber septa, saving you time and money.

Merlin MicroShot

The Merlin MicroShot injector improves your manual injection instantly, making manual syringe injections convenient and reproducible with a unique trigger mechanism which makes each injection automatic.

Custom Design

Merlin Instrument Company has over 30 years of experience in designing and manufacturing custom passive sampling valves for a variety of applications. Please email us at or call to discuss how we can apply our experience to help solve your sealing and sampling problems.
