The pressure chamber is commonly used to evaluate plant water status. The compression sleeves supplied with commercial units provide inadequate seals on irregularly‐shaped, succulent stems or petioles of organ samples. This makes accurate measurements of the water status of organs difficult, if not impossible. This note briefly describes a technique for making customized seals by molding them out of silicone rubber directly onto representative stems or petioles. Such seals have been demonstrated to provide superior sealing action with little or no tissue change.
