General description

Designed for stirring in awkward vessels, for gently mixing staining solutions above delicate gels, or for quickly dissolving chemicals. A small flat capsule contains the magnetic stirring bar that spins freely inside without contact with the vessel bottom or gel. The protective capsule is molded with polystyrene and shelters a Spinbar magnetic stirring bar which is molded with inert PTFE. Bar diameter is 1 3/16 in.

    Anabolic androgenic steroids are considered to be doping agents and are prohibited in sports. Their metabolism needs to be elucidated to allow for urinary detection by gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-tandem mass spectrometry (LC-MS/MS). Steroid metabolism was assessed
