Yes,
EasySampler can sample reactions under pressure if all the following reaction conditions are met:  Pressure range: 1.013 bar – 10 bar (14.7 – 145 psi)  Temperature range: 20 to 100 °C  Reactor volume: up to 2500 mL  Number of samples per sleeve: 1 reaction (with up to 24 samples) High-pressure adapter: An appropriate high-pressure adapter (P/N14474404) must be used to securely position the EasySampler probe in the reactor Note: Use of the EasySampler probe at elevated pressure (between 1.013 bar to 10 bar) will reduce the temperature range to 20 °C to 100 °C, the maximum reactor volume to 2500 mL, and the maximum number of samples per sleeve to 1 reaction (with up to 24 samples).
