Select Gases, LLC

Select Gases, LLC, a self-certified small disadvantaged business based in Norcross, Georgia, supplies specialty gases, cryogenic equipment, and related services to federal civilian agencies as a prime contractor, with a federal footprint concentrated on hydrogen propellant delivery and cryogenic biological research support for the Centers for Disease Control and Prevention and the Defense Logistics Agency Energy.

Select Gases operates as a limited liability company, for-profit entity, and competes exclusively under full-and-open designations; while the vendor holds self-certified small disadvantaged business status, recent awards carry no set-aside designations, and the vendor's significant federal contracts include several set aside for total small business (Department of Veterans Affairs, U.S. Army Criminal Investigation Command, and prior CDC BPA rounds). The company is organized around NAICS 325120 (Industrial Gas Manufacturing) and PSC category 4730 (Gases: Compressed and Liquefied), with secondary NAICS around refrigeration equipment manufacturing (4822) and analytical laboratory instrumentation (3826).

The vendor's customer concentration is extreme: the CDC Pittsburgh accounts for 98% of recent award count (33 awards, $23.4 million combined potential value), with the remaining 4% split among the Defense Logistics Agency Energy (26 awards, $854 thousand), the Department of Veterans Affairs, the Food and Drug Administration, and the U.S. Army Criminal Investigation Command (2 awards each). The dollars track the count — CDC dominates on both dimensions, anchoring most of the $25.5 million in combined potential value across 66 prime awards. This concentration reflects Select Gases' core delivery: cryogenic biological research liquid nitrogen freezers, racks, support services, and related consumables (liquid argon, dry ice, mixed gases) to the CDC's Biorepository and laboratory operations across multiple locations, alongside hydrogen propellant delivery orders to DLA Energy for Department of Defense support.

Representative capability work includes a $121.7 thousand CDC purchase order (August 2026) for up to four MVE 1426F liquid nitrogen freezers with magnetic lock systems engineered for Tier 1 Select Agent storage in a BSL-4 environment, complete with trained installation and service personnel, NIST-traceable temperature testing, and TEC-3000 monitoring system integration; a $338.2 thousand FDA purchase order (June 2025, set aside for total small business) for bulk gas tank rental and ultra-high purity liquid nitrogen and argon delivery to the Atlanta Human and Animal Food Laboratory (1.82 million standard cubic feet of nitrogen, 276 thousand standard cubic feet of argon annually, through May 2030); a $252.6 thousand Army Criminal Investigation Command purchase order (February 2024, total small business set-aside) for specialty and industrial grade lab gas delivery service to Gillem Enclave, Georgia through February 2027; and recurring DLA Energy delivery orders for hydrogen propellant ranging from under $400 to $26.7 thousand per order.

Select Gases holds a $17.5 million five-year blanket purchase agreement with CDC Pittsburgh (the source identifies this as a landmark vehicle across multiple award summaries, though the specific vehicle identifier is not named in the source) that has generated over $5 million in task orders to date for cryogenic biological research equipment and services. The vendor also operates under a $1.11 million CDC BPA for liquid argon and dry ice delivery (NCEH program, August 2024 through August 2029, single-award, competitively set for small business), a $130 thousand single-award Veterans Affairs IDIQ for medical gas and cylinder rental services (September 2026 through September 2031, total small business set-aside with $5 thousand guaranteed minimum), and four Defense Logistics Agency Energy IDCs for hydrogen propellant with individual ceilings ranging from $39,100 to $491.6 thousand and performance periods extending through November 2029. These five parent vehicles account for 40 of the 66 prime awards in the source data.

Activity has remained relatively steady over the past five years — between 6 and 14 awards per year, with 11 awards in the most recent year (2026) — though obligated dollars ($5.2 million to date) represent only 20% of combined potential value across the portfolio. Five awards with combined potential value of $471 thousand reach ultimate completion within the next twenty-four months, creating modest recompete risk for the vendor. The Service Contract Inventory dataset shows minimal SCI-reportable service-contract activity: three records across FY2022 to FY2025, all filed as named subcontractor records totaling approximately 3.0 FTEs in FY2024 and FY2025, which suggests Select Gases' federal footprint consists almost entirely of product procurements (gases, freezers, tanks, related equipment) rather than labor-intensive services captured in SCI. Select Gases operates exclusively as a prime contractor — the award portfolio carries zero subcontractor records — and does not engage material subcontractor leverage on its federal work.
