Technical Services

The LilaLab will occasionally perform analyses on our specialized scientific instrumentation on a fee-for-service basis to outside contractors or research teams. Established rates, subject to change, are intended to cover the costs of lab instrument maintenance, disposables, solvents and other chemicals, and time for LilaLab personnel to perform sample runs and analysis.
