TEM grids with support film



The EM Resolutions team have many years experience working in the Microscopy industry. We have been making high quality support films and calibration standards for over 20 years and now supply these and other consumables for Electron Microscopy direct to customers all over the world. EMR TEM support films are produced with the requirement of the electron microscopist in mind. The clean production techniques yield reliable, consistent quality TEM support films without contamination issues. Stringent quality control procedures include checking with a TEM.

Carbon film on grids

Carbon support films provide a continuous thin electron transparent support for viewing nano and virus like particles. They also provide increased stability of specimens when imaging at very high magnifications. A good solution for imaging nanoparticles. Carbon film thickness is in the range of 15-20nm providing a thin consistent carbon film. If your application requires a slightly thicker or thinner film then please tell us and we can modify future orders to your requirements.

Holey, Lacey film on grids

Lacey Carbon support films provide a wide range of hole sizes and offer a cost effective solution where are a continuous film is not desirable. Lacey Carbon supports are stronger than Holey carbon supports and ideal for specimens requiring more rigorous pre-treatments. Our experience of developing methods over 30 years enables us to have greater control over the formation of the holes. If your application requires a particular hole size or you would prefer slightly thicker or thinner film then please tell us and we can modify future orders to your requirements. Also included in our range is a Lacey Formvar Carbon support film that retains a Lacey Formvar backing for additional strength.

Graphene film on grids

Graphene Oxide are super thin (<1nm) naturally hydrophilic support films. Pre-treatment of GO support films is not necessary before using. The hydrophilic surface will facilitate the even spread of particle suspensions across the grid. We would actively discourage any form of plasma cleaning or glow discharge as it will damage the support film.

Graphene and Graphene Oxide (GO) have been known for some time to offer distinct benefits as thin support films for TEM. Whilst Graphene grown by CVD offers the possibility of a continuous film the methods of production are technically complex and expensive for large scale manufacture of coated TEM grids. Graphene oxide offers a cost effective alternative to Graphene. GO monolayers are typically 50% thinner than the equivalent carbon support film offering an ideal solution for viewing nanoparticles by TEM where a continuous support is necessary. Graphene oxide films are almost transparent under the electron beam and not easily visible under an optical microscope. As part of our quality process we check each batch using TEM imaging and diffraction to characterise the grids.

EM Resolutions can offer coated grids with a varying thicknesses of GO to best suit your application. When deciding which is best for you one needs to consider a compromise between grid coverage vs the number of layers (thickness of GO).

We ensure that the GO covers a given % of holes in the support film using three key metrics:

(1) % of the area of the grid holes covered (coverage)

(2) the average number of GO layers across each hole

(3) what % of the covered holes are monolayer.

For good ‘monolayer’ coverage we would expect ~ 50% coverage, of which the majority is monolayer (i.e. a total of ~ 30% monolayer across the grid area). Depending on your application you need to decide if it is more important to have high coverage or a high monolayer fraction.

For good overall coverage of> 80% coverage we would expect typically 2-3 layers of GO with < 20% as monolayer GO. These films are ideal for carbonaceous particles where carbon supports cannot be used.

EM Resolutions offers GO support films on a range of carefully selected coated grid types. We use holey and lacey support films on hexagonal grids to ensure the most even coverage of GO that is suitable for your application.

Silicon Nitrite Membrane

Silicon Nitride membranes (TEM windows) have the advantage of being chemically inert and mechanically robust, being able to withstand temperatures >1000°C. They are particularly suitable for conducting nanotechnology experiments directly on their surface over a wide temperature range. Silicon Nitride grids are compatible with correlative negative staining electron microscopy and tip-enhanced Raman spectroscopy for use in the detection of micro-organisms.
