Request InfoElliot Scientific Ltd.Elliot Scientific Ltd. has unveiled the E4100 QPD force measurement optical tweezer system, which uses a quadrant photodetector in conjunction with software to identify and measure the single trap stiffness of a captured particle. The instrument offers several configurations for determining the interaction between laser-applied forces and a trapped particle. The company can supply a complete plug-and-play system, or it can add the capability to an existing tweezer installation or retrofit a microscope.See full productRelated content from Photonics MediaPRODUCTSBioPhotonics Nov/Dec 2023 IssueFLIM Camera SystemThe LIFA vTAU from Lambert Instruments is a camera-based system designed to transform fluorescence lifetime imaging microscopy (FLIM) for live cell applications.
