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 Laborlux 12 Binocular

Leitz microscopes populated pathology laboratories in their time more than any other make. The reason for this is simple - they were (are) exceptionally good. This is optically a fine microscope but because (just like the owner of this business!) It is getting on a bit there are some marks on the paint work at the edges of the base that would have been caused by the rubbing of watches and bracelets. The surface of the stage also shows the evidence of slides moving in and out. Binocular head with periplan x10 eyepieces. Objectives x4, x10, x20, x40 and x100 (oil immersion). Full mechanical stage with drop down controls. Flip top condenser with paddle control and lateral adjusters. 6v 20watt Kohler illumination with field iris and brightness control. An opportunity to get a top class laboratory microscope without breaking the bank!

Leitz SM-LUX Binocular

A good example of the ‘work horse’ of the Leitz range. The body work and stage surface of this unit is very good condition, in particular the stage surface is particularly good for its age. Kohler illumination with a field iris to the front of the stand and an external light box to the rear with a modern 6v 20 watt transformer box. Click stop rheostat controls. Full mechanical stage with drop down controls and a focusing condenser with flip top lens. 170mm tube length objectives plan x4 (0.12), EF x10 (0.25), plan x25 (0.40) and NPL fluotar x40 (0.70).

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.

Price £41.67 + vat

Leitz 1/7a Objective

A good vintage Leitz objective with original objective case. Marked as 1/7a this is approximately - using the Leitz literature - a x54 oil immersion lens with a numerical aperture of 0.95. RMS screw thread and corrected for 170mm tube length.

Leitz Diaplan Trinocular

The Diaplan was the flagship model during the heyday of the Leitz brand. These are now well sought after and this particular model is in very good condition indeed. This is a heavy weight microscope commanding a large foot print. The trinocular head allows 100% of the light to the eyepieces, 50/50 to the eyepieces and photoport or 10% to the eyepieces and 90% to the photoport and has x10 periplan eyepieces with integral eyecups that are suitable for spectacle wearers. The five position turret has plan x2.5 (0.08), NPL fluotar x4 (0.12), NPL fluotar x6.3 (0.20), NPL fluotar x25 (0.55) and an NPL fluotar x40 (0.70)  The mechanical stage surface is remarkably free of surface marks for its age and has the ability to be rotated when the locking screw is released. Double vernier scale and coaxial movement controls.

The substage has the classic ‘paddle’ movement of the upper auxiliary lens, with full lateral movement and focus controls. Both the aperture and filed iris diaphragm controls are wheels embedded in the left hand side of the base. The coaxial coarse and fine focus controls also have a maximum distance control mechanism below the focus controls on the left of the stand.

The external light box houses a 100 watt halogen light source with full bulb positioning control and filter slots. The rheostat control is on the right side of the base towards the back and at the front of the base is a volt meter display. All in all a fine microscope made the way that microscopes should be.

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!

Price £229.17 + vat

Leitz SM-LUX Trinocular

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 SM-LUX is one of these,  all original and in excellent condition. Trinocular head with x10 periplan eyepieces. Four position objective turret with 170mm x4, x10, x40 and x100 objectives. Mechanical stage with drop down coaxial controls and substage condenser. Kohler illumination with rheostat controlled halogen illumination. The body work and stage are in excellent condition. Recommended. This could also be described as a collectors piece.
