Microscope Slides Our microscope slides are made under rigorous scientific control. They are the product of long experience combined with the most up to date techniques. The prerequisite for excellent preparations is good material, well preserved and fixed so that the finer structures are retained in as life-like a way as possible. Microtome sections are cut from this material by highly skilled and experienced staff. They are of a thickness which will finally result in slides from which the maximum resolution of the structural components can be obtained. Particular attention is paid to the staining technique and in each case the selected method for a particular specimen will ensure the best possible differentiation combined with clear definition and permanency of staining. The prepared microscope slides are delivered on best glasses with fine ground edges of the size 26 x 76 mm (1 x 3") and are mailed in solid boxes. All slides can be purchased either in complete sets and series or individually. For individual orders please use the products number W....and add /1 etc. We reserve the right to make minor alterations to the sets and compilations. The delivery time is between 6 - 8 weeks.
