Reliable Gamma Counters Since 1983

From the world-renowned Genesys 5000 that launched our company to the Wiper™ series built specifically for nuclear medicine departments.

Our Company

Founded in 1983 by lead engineer Donald Oesterlin, Laboratory Technologies, Inc. was built on deep expertise in gamma counting systems. The Genesys 5000 quickly became an industry standard, with thousands of units still operating decades later. In 1995 we developed the Wiper to meet the need for a better wipe test counter. In 2003 we released the Multi-Wiper — the first multi-well gamma counter designed specifically for nuclear medicine departments.

Who We Serve

Built for nuclear medicine, pharmacy, and research workflows.

Nuclear Medicine

Hot lab wipe surveys, weekly area surveys, and contamination control — from compact single-well counters to high-throughput Multi-Wiper™ stations.

Nuclear & Hospital Pharmacy

Compounding rooms, dose-calibration support, and spill response for both radioactive and hazardous drug incidents — all from one supplier.

Research Laboratories

Robust data reduction and curve fitting built for RIA and gamma-counting research — linear, semi-log, log-logit, four- and five-parameter logistic, cubic spline, and percent-bound fits, with full statistical analysis and exportable results.

EMS & Emergency Services

We help ambulance crews and first responders quickly remove radioactive, hazardous drug, chemical, and biological contamination between patient transports — even when the nature of the contamination is unknown.

The original LTI Genesys™ 5000 gamma counter
Our Legacy Product · Retired

The Genesys™ 5000 — the instrument that started it all.

The Genesys™ 5000 was the foundational instrument that built Laboratory Technologies. Released as the cornerstone of LTI's RIA program, it redefined what a gamma counter could be — fully solid state, single-source calibrating, and dependable enough to run a clinical or research lab around. Hospitals, radiopharmacies, and research institutions worldwide built decades of work on top of it.

The 5000 is officially retired today, but its DNA runs through every instrument we ship. Every Multi-Wiper™, every Genesys™ Genii, every Wiper™ Gold inherits the same philosophy: no moving parts, owned in-house engineering, and service answered by the people who built it.
