Aluminium alloy plataform with antioxidant treatment and epoxy paint.MicrotomyTo allow analysis of tissue by light microscopy, they must be sectioned into thin and uniform slices. The optimum thickness may varies with the purpose of the study; it is recommended that the thickness from 4 to 6 mm in routine laboratories.The instrument able to fabricate cuts with such precision is the microtome, consisting of three parts: body, block holder and object holder. It is considered also that some models have two handles, an adjustment crank and another cut.Rotary Microtome is the smallest and most used instrument for light microscopy included in paraffin and tissue. Aluminium alloy plataform with antioxidant treatment and epoxy paint.Developed for precise and sequential paraffin and resin material cuts, through holder and tungsten razors (optional).Manual cutting system operated by right sided main wheel and advance, retreat and thinning operations by left sided wheel.Main wheel lock system in any position as safety measure or additional mechanical lock system in 12 hour position.Thickness cutting selection between 0,5 to 60 micron. Allow material cut in larger areas.Micrometer advance and retreat system of the specimen through turnstiles and vertical guide system of slipping system through roller lubrification free.Self-retraction manufactor adjusted system to 200 micron, preventing contact between sample and razor on every cut during the return to top position.
