The Supelco hand held crimper provides a consistent and dependable seal that allows secure vial closure each and evey time. The high quality construction is engineered for durability and long life to provide a smooth and simple operation.
Hand crimper may be used to seal a glass vial containing MeOH, for high-performance liquid chromatography-diode array detection (HPLC-DAD) analysis, during polyurethanes (PUs) analysis and clean-up, in an experimental study done in order to develop, optimise and apply PU as new polymeric phases for stir bar sorptive extraction.

In this contribution, polyurethane foams are proposed as new polymeric phases for stir bar sorptive extraction (SBSE). Assays performed for polyurethane synthesis demonstrated that four series of formulations (P(1), P(2), P(3) and P(4)) present remarkable stability and excellent mechanical resistance...
