About KinTek Corporation
Advancing enzyme kinetics research since 1987 with precision instrumentation and expert consultation.
Established in 1987
KinTek Corporation specializes in precision stopped-flow and quench-flow instruments for rapid transient reaction kinetics research. Since our founding in 1987, we have been at the forefront of developing innovative instrumentation and software for kinetic analysis on the millisecond timescale.
We manufacture the SF-300X Stopped-Flow instrument, RQF-3 Rapid Quench-Flow instrument, Auto SF-120 system, along with related software and parts. Beyond instrumentation, we provide comprehensive support including instrument consultation, technical assistance, and educational workshops on transient-state kinetic methods.
Our founder, Dr. Kenneth Johnson, shares his expertise through Kinetic Analysis for the New Enzymology, available exclusively through KinTek. All instruments come with a comprehensive two-year warranty.
