Bivalve mollusc

Transmission electron microscope image of a section through part of the gill of the bivalve mollusc Anodontia ovum. It shows an intercalary cell surrounded by two bacteriocyte cells filled with chemosymbiotic sulphide-oxidising bacteria and glycogen granules. The intercalary cell shows several mitochondria and a golgi body. Spiruliform bacteria are in the cell lumen.

Key facts

Technique: transmission electron microscopy

Magnifications: 1000x-300,000x

Image output: 8-bit and 16-bit TIFFs up to 2672x2672 pixels

The Hitachi H-7100 transmission electron microscope (TEM) combines high image contrast with high resolving power, and is designed to prevent beam damage to delicate or sensitive specimens.

The Hitachi H-7100 has a wide range of automated features, allowing for the swift examination of specimens. Its multiple specimen holder allows three grids to be introduced into the column at one time. The tilt-azimuth holder is used for examining features where orientation is important.

A digital camera allows real-time visualisation of the sample as well as digital image capture and output.
