Hours of Operation


9:00 am to 5:00 pm, Monday-Friday; Closed weekends and UF holidays*

**Our after-hours sample drop-off cooler is always ready for your samples, even when the lab is closed. In-person delivery works best, or you can indicate to a courier that they should leave the package in the cooler. Make sure the package does not require a signature. We do not recommend that you use the US Postal Service; they will not deliver after-hours, on weekends or during UF holidays.

As a University of Florida laboratory, we follow UF’s closure schedule. We also close for the last two weeks of December to close out samples, bookkeeping, and projects.
