Featured TEM Grids and Supports

C-flat™ - the premier holey carbon grid for cryo-TEM

C-flat™ provides an ultra-flat surface holey carbon-coated TEM support grid that results in better particle dispersion and more uniform ice thickness. C-flat™ ensures the most accurate and consistent hole shapes and sizes down to submicron features. Artifacts such as excess carbon and edges around holes are eliminated. Unlike competing holey carbon films, C-flat™ is manufactured without plastics.

C-flat™ holey carbon grids provide the ideal specimen support to achieve high resolution data in cryo-TEM making them an ideal choice for single particle analysis, cryo electron tomography and automated TEM analysis. Read more

Quantifoil® - Holey Carbon Films

QUANTIFOIL is a perforated support foil with pre-defined hole size, shape and arrangement. It has advantages in electron microscopy (EM) or low-energy electron point source (LEEPS) microscopy when compared with conventional holey film.

QUANTIFOIL is offered with circular and square, orthogonal arranged holes. Films with different hole sizes and bar widths are available. It is generally delivered as a carbon foil; it can be reinforced with plastic film. QUANTIFOIL is a superior quality of holey carbon film, which facilitates the use of automation in TEM. Read more

Citifluor™ – Anti-fading Mounting Solutions

Antifadent Solutions reduce the photo-bleaching, or fading of the fluorescence of dyes used for labeling biological species.

The most frequently used solution is AF1 which is an anti-fadent (anti-bleaching agent) contained in a glycerol PBS (phosphate-buffered saline) solution and is particularly useful for examining tissue sections. AF2 solution contains the antifadent in glycerol which enables users to choose their own buffer, and AF3 is the antifadent in PBS solution. AF3 is particularly useful for examining live cells.

All solutions may be stored at room temperature.

UranyLess - Substitute for Uranyl Acetate

A new contrast stain solution for TEM, for all of your negative staining applications. It is an amazing substitute for Uranyl Acetate with similar results. After only a minute of contact, UranyLess‘ fast-acting, non-radioactive lanthanide mix is finished staining your sections or deposits. UranyLess has been tested on many biological tissue (animal and plant): intestine, skeletal and cardiac muscle, liver, kidney, adrenal gland, nerve, cell culture, plant tissue, and also on negative staining of bacteriophage, bacteria, and polymers.
