The Brunel SP27 is an established microscope in our series for student and amateur use. This is an extremely versatile instrument with excellent LED illumination that allows the instrument to be used away from an electricity supply. An excellent specification including rotating monocular head with a x10 widefield eyepiece, four position turret with x4, x10, x40 and x100(oil) achromatic objectives together with a good sized full mechanical stage with coaxial drop down controls and a double vernier scale.
The SP27 has a modern design with low position coaxial coarse and fine focus controls and a focus safety stop. The Abbe condenser has an iris diaphragm with filter carrier and the base has a very effective field lens that gives a good even field of illumination.
The LED illumination has a rheostat control that gives excellent lighting well suited to the requirements of the x100 objective. This can be used either directly attached to a 240v electricity supply or can be run from the integral battery system that will give up to 48 hours continuous use between charging which happens automatically when the unit is plugged in.
