The popular 5040 microtome is of rotary retracting, self-lubricating design and has a heavy cast alloy base and cutting arm. Its robust construction makes it accurate and incredibly reliable. The use of fixed beryllium hinges means that all lateral motion is controlled and allows no slop or play that can be experienced in other, lesser designs which can result in ‘chatter’ and ‘thick and thinning’. It’s pawl and ratchet wheel and head-advance design ensures absolute calibration for section thickness accuracy and repeatability.
It is well suited to cutting hard specimens such as undecalcified bone and acrylic resins, while routine wax sections can be produced simply and swiftly. Its use in the OTF5000 cryostats makes it the ‘workhorse’ of the Bright range. Based on Bright’s previous model 5030 microtome, the 5040 microtome is now extensively used world-wide in pathology/histology laboratories and many life sciences teaching and research laboratories. Other applications include materials testing, food science and botanical research. The 5040 is available in three versions (see ordering information), for wax sections with fine adjustment specimen orientation, for wax sections without specimen orientation and the cryostat version. Strong, rigid and almost maintenance free, the 5040 will give many years of reliable service.

A VERSATILE MICROTOME
A wide range of options and accessories increase versatility and widen the scope and ease of use of the microtome. Motorised drive is available which, whilst still permitting manual control, facilitates extra slow cutting for added power free from vibration, and allows ultra-repeatability of sections. Motorised advance/rewind is also available; this function has two speeds for accurate and rapid alignment of the specimen to the knife. It has a knife holder block that can be fitted with many different types of knives including tungsten carbide tipped knives and a special quick release holder block is available that accepts FeatherTM disposable blades, also an angled knife block is available for extra hard specimens. Other items include mechanical or electronic section counters and a ‘hands-free’ foot pedal.
The 5040 is available with or without specimen orientation and orientation may be coarse or fine. A quick release cassette holder can replace the standard vice clamp if required and a version is also available to take ‘supercassettes’.
The unique design of the 5040 allows different feed screws to be fitted to change the operating range of the section thickness control, thus giving choices between 0.2μm and 300μm section thickness’. Using the combination of 0.2μm - 12μm advance and a triangular or Ralph glass knife, it is possible to cut sections of plastic embedded tissue down to 1 - 2μm. When used in its cryostat form, the 5040 is complimented by the Easi-Set anti-roll plate which enables the easiest of all setting up procedures and cutting preparation times are kept to an absolute minimum.
