The Ryberg Lab has two primary laboratory spaces with distinct purposes. The Water Quality Innovation Lab is located on the third floor of the Agricultural Biotechnology Laboratory (ABL), right next to the UConn Dairy Bar with views of the dairy herd on Horsebarn Hill. The Disinfection & Toxicology Lab is located on the third floor of Koons Hall, with beautiful views from its central location on UConn’s campus.
Outside of these spaces, the Ryberg Lab has access to numerous shared resources. The most frequently used of these include the shared Tissue Culture Lab in ABL 310, an autoclave facility in ABL 324, a MilliQ Ultrapure water generator in ABL 217, several smaller pieces of equipment available on the 3rd floor of ABL, and the numerous UConn Core Facilities for access to advanced instrumentation, especially those at the Center for Environmental Science & Engineering.
The photos below show these lab spaces and a selection of the equipment found in the Ryberg Lab.
The Agricultural Biotechnology Laboratory, where the Water Quality Innovation Lab within the Ryberg Lab is located.Half of the workbenches in the Water Quality Innovation Lab, specifically showing the larger equipment.The second half of the workbenches in the Water Quality Innovation Lab, specifically showing the fume hood.The SunTest XLS+ is a high-capacity solar simulator, allowing many samples to be irradiated simultaneously.This Agilent Cary 60 UV-Vis spectrophotometer is outfitted with the 18-cell multicell changer accessory, allowing numerous samples to be queued and run sequentially, saving students’ time and increasing productivity.This Ocean Optics system provides the Ryberg Lab a variety of capabilities. Our workhorse for full-spectrum radiometry, absorbance, fluorescence, and reflection spectroscopy measurements, it is a highly useful instrument for photochemical experiments. We also possess a fully calibrated light source, allowing in-house calibration.The Thermo Vanquish Flex is a UHPLC system that the Ryberg Lab uses to quantify contaminants in water and indirectly measure reactive species via probe compounds. Our system possesses both a diode array detector and a fluorescence detector for quantifying a variety of chemicals.The BioTek µQuant plate reader is used for absorbance-based toxicological assays, and the ELx405 plate washer greatly reduces the manual pipetting of these assays.Koons Hall, where the Disinfection & Toxicology Lab within the Ryberg Lab is located.Housed in Koons Hall, the Disinfection & Toxicology Lab is a great space to conduct various biological experiments.The Disinfection & Toxicology Lab has a biosafety cabinet, a cryogenic storage system, a -80°C freezer, and an incubator.The Disinfection & Toxicology Lab also has an autoclave, heated bath, electrophoresis system, and a UV-vis spectrophotometer.Within view of the ABL, the UConn Dairy Bar is the preferred venue to celebrate the accomplishments of students within the Ryberg Lab.
