|A lacey network support film. The holes in the lacey support film vary in size from less than a quarter micron to more than 10 microns making them ideal for any type of specimen. Lacey support films are extremely strong and withstand vigorous specimen preparation treatment. The specimen material is supported by the film network but lies across or protrudes into the holes of the mesh. This allows high definition imaging without the effects of underlying support material. Lacey films can be used for specimens ranging from large crystals and other particulate material to virus particles. Smaller particles, such as viruses or bacteria, tend to adhere around the inner edges of the holes, an ideal situation for high resolution microscopy. Lacey films are also ideal for selected area electron diffraction imaging. We offer four types of lacey film.产品信息：(a) Lacey Formvar Stabilized with Carbon: A Lacey Formvar film with the lacey structure enforced by a heavy coating of carbon. Holes are completely open. 产品规格和包装：(b) Lacey Carbon Type-A: A Lacey carbon film with a removable Formvar backing on the opposite side of the grid. When the Formvar is removed, by dipping in solvent, the Lacey carbon film remains. These films are stable under all EM operating conditions and for use where the presence of Formvar can not be tolerated. Pure Lacey Carbon is more delicate than those with Formvar backing and require more careful handling during specimen preparation. Holes are completely open. |
(c) Lacey Formvar Stabilized with Silicon Monoxide: A Lacey formvar film with lacey structure enforced by a silicon monoxide coating. Holes are completely open.
(d) Lacey Carbon Films with No Formvar: Holes are completely open.
