Leitz Laborlux 11 Binocular

The Leitz Laborlux 11 was generally regarded as one of the best value microscopes of the Leitz range. This particular model is binocular with periplan x10 eyepieces. Full mechanical stage with drop down controls. Critical illumination with brightness control. Objectives Plan x20 and x100 (oil) immersion and Leitz x10, x40 and x50 (oil) immersion 160mm tube length objectives. The body work is very good although the stage surface does show the effect of slides being slide on and off during the years. 6v 20watt rheostat controlled halogen illumination. All in all this is an excellent opportunity to obtain a Leitz microscope for an extremely good price. This is a bargain.

Leitz Projection Attachment

Before the digital world with its cameras and projection devices arrived, it was somewhat unique to be able to share microscope images with others. This Leitz projection attachment was designed to do just that. It clamped over the eyepiece of a microscope and its prism deflected the image that the microscope saw to a screen. A part of our microscope history.

Leitz Dialux 20

The Leitz Dialux 20 was the research laboratory ‘go to’ microscope during the time when Leitz microscopes were without equal. This unit is in very good condition with all its original features with the added bonus that it has been converted to LED Kohler illumination.  Plan objectives x4, x10, x40, x50 (oil immersion) and x100 (oil immersion). With the periplan x10 eyepieces gives an overall magnification of x40 to x1000. Obviously, laboratory microscopes will show some signs of ‘wear’ but this unit is in very good condition and has clearly been looked after during its use. Most noticeable is the surface of the stage which can be marked by the slides that are viewed over the years. However, as with the rest of the microscope the signs are wear are relatively minimal.


Full mechanical stage with drop down coaxial controls and substage Abbe condenser with flip top lens and iris diaphragm. Classic coarse and fine focus controls. Kohler illumination with brightness control through the LED unit which uses all other parts of the microscope. This is a really good opportunity for a classic microscope with an up to date improvement.

Leitz Laborlux K Binocular

Leitz manufactured a series of Laborlux instruments with the differences between models often quite relatively small because they all largely had the same optical objectives and eyepieces. This good example is from the K range. We have sold many used Leitz microscopes over the years and they all share one common property - excellent build and optical quality. This microscope has all the Laborlux features. Binocular head with x10 periplan eyepieces. 160mm tube length x4, x10, x20, x40 and x100 (oil immersion) objectives. Mechanical stage with drop down controls. Flip top condenser with lateral adjustment . Kohler illumination with a 6v 20watt halogen light source with brightness control. As would be expected the base of the microscope shows some loss of paint at the edges (caused by watches and bracelets over the years) and the stage shows the evidence of slides moving around. A quality microscope that becomes affordable simply because it is getting on a bit!

Leitz Dialux 22 Binocular

The quality of Leitz microscopes speaks for itself, but from time to time we come across models that have been owned from new by private individuals and have been looked after with care and used with knowledge, This Dialux 22 is one of these,  the body work of the stand is very good for its age and the stage has only one small area of wear caused by slides. Binocular head with x10 periplan eyepieces. Four position objective turret with 160mm Leitz x10, x40 and x4, x25 and x100 new plan objectives.

The surface os the stage is good and generally the body work is in good condition however there is some wear to the paint on the edges of the base which is usually caused by watch straps and bracelets over the years. All in all a fine microscope with a very good specification.

This is in superb condition for its age and is complete with its original monogrammed case. Made from brass it has the usual X and Y rack and pinion movement.
