The cylinder is transparent and can be of glass or plastic with volume markings on the outside. The syringe also has a cylindrical holder (7), which is fitted on the outside of the cylinder. The holder upper end is provided with vanes (9) which the user grips together with the upper part of the piston in order to press out the cylinder content. The holder lower part is partly provided with a recess which uncovers the cylinder narrowed outlet part and partly with an inner extension (12).
