Heading to SES?

Stop by and talk with Apex team during the Poster Sessions and connect with our account executives, Jackson Yarbrough and Tyler Mills.

They will be presenting: "Mitigating Risk in Source Sampling: Addressing Glassware Fragility and Handling Hazards."

They will explore safety risks associated with glassware used in EPA source sampling, and will cover hazards such as breakage, handling injuries, and mechanical stress in extreme field conditions. Learn how our improved impinger designs reduce injuries and mitigating risks.

Stop by to discuss your sampling challenges, review our latest safety-focused solutions, and explore how to make your next test safer and more reliable.

Hexavalent chromium compliance on your test plan?

EPA Method 0061 is the standard for measuring Cr(VI) emissions from hazardous, municipal, and sewage sludge incinerators. Apex Instruments provides the equipment you need to run it with confidence.

Our Method 0061 sampling trains are designed for isokinetic sampling with continuous impinger reagent recirculation and ion chromatography analysis. For high-temperature sources above 150°C (300°F), our Method 0061H Hexavalent Chromium High-Temperature Source Sampling Kit is the preferred alternative.

See how Apex can support your Method 0061 testing and cover your Cr(VI) sampling needs:

Apex Instruments is heading to Kingsport, TN for the SES (Source Evaluation Society) Annual Conference.

Will you be there? Our team will be on-site all week!

If you’re attending SES, stop by to compare notes and see what’s new in stack testing at Apex. We look forward to connecting in Kingsport!

Need reliable impingers for your next sampling run?

Apex Instruments offers a full line of GT and GH impingers engineered for safer handling in the field.

Our GT Series Glassware offers a tapered, stable connection between insert and bottle for a secure seal, plus an easy‑to‑remove insert for faster change‑outs and cleaning.

Additionally, our GH Series Glassware uses a silicone gasket, threaded cap, and inner taper to hold the insert steady and create a durable, high‑vacuum seal—without grease. And, every set comes with our hybrid impingers insert removal tool.

GT and GH impingers can be used together or as direct replacements for existing isokinetic impingers (GH, GT, and GN series).

If you’re running OTM‑50, be sure to review our midget glassware options as well. You can also order replacement bottles and inserts to keep your glassware in service longer.

Keeping your stack test train under control on a crowded platform is a challenge.

The Apex Monorail Kit is designed for stack platforms—supporting your probe, umbilical, and heated sample line on a single, rugged track so everything stays organized, elevated, and easy to move. That means fewer snags, faster setup, and safer walks across the deck during Method 5 runs.

Available in 4–12 ft lengths.
