Pyser Optics Graticules Division is teaming up with Labtech to supply high quality TEM support grids to the British market.
Labtech is an East Sussex based leading supplier and service provider for scientific instruments and consumables since 1993. The team within the EM division in Labtech has an extensive knowledge in electron microscopy preparation and offers a large range of accessories, consumables and instruments for electron microscopy including Pyser’s TEM Grids.
What is an EM Grid? EM grids are generally only used in transmission electron microscopy (TEM). An EM grid is typically a flat foil disc with a mesh or other shaped holes used to support a thin section of specimen. The holes in the grids allow the electrons to pass through. They are available in a wide variety of patterns and materials to suit various applications.
Pyser optics TEM grids are recognised around the world for their superior quality. Pyser have been manufacturing specimen support grids for electron miscroscopes for over 45 years using the extensive knowledge of processes and techniques from their micropattern production. In 1994 the acquisition of Brandsma BV grids production (Known as Embra grids) allowed Pyser to extend their existing Maxtaform range of grids and meet the majority of requirements. All Pyser grids (except the value range) are 100% inspected so you know that any grid you take from the vial will be useable.
Our electron microscope support TEM grids are available in a large variety of materials as some specimens will react with certain materials and some require analysis at higher temperatures.
Normal materials are copper, nickel, gold, molybdenum, titanium, stainless steel and aluminium. Some copper grids are flash coated on one side with either rhodium or paladium to enable users to differentiate more easily between the faces and to stop tarnishing. Most grids have one shiny side and one matt side. Grids are normally supplied in anti-static vials to make them easier to remove and use.
Many specimens will require an additional support on top of the grid to prevent them from falling through the holes. In these cases, a carbon or formvar coating is formed across the surface to provide support without interfering significantly with the flow of the electron beam.
Special types of grids such as Finder or Index grids are used to identify specific areas of interest in specimens. This allows the interesting area to be relocated later or logged for reference.
We look forward to a long partnership with Labtech to supply and support the Electron Microscopy Sector. Electron microscopy revolutionized the microscopy world by using beams of electrons instead of rays of visible light to obtain high resolution images of small biological and non-biological specimens. It has improved magnification drastically, with modern electron microscopes we can now magnify objects up to two million times which helped scientists to observe key features on the structural basis of cells, microorganisms, large molecules, biopsy samples, metals and crystals.
