The BD stand is a Pole type stand with an F focusing slide block and an adjustable rotatable mirror in its base for “pseudo darkfield illumination”. The BD stand is an excellent tool for both biological and medical investigations - it can be an effective tool used at high magnifications to view living bacteria, or at low magnifications to view tissues, cells or embryo transfers.  This stand comes equipped with two stage clips, as well as a rear illumination port. The BD stand will require an optional external light source: MA264/LED (LED light source) or MA264H (Halogen light source) or FL150/115 with FL150/12 and FL150/50 focusing lens fiber optic halogen light source system.
