23810 | MacroView™ Otoscope

  • 30% greater magnification and twice the field of view of a conventional otoscope give a large, almost complete view of the tympanic membrane.
  • Focusing wheel enabling you to zoom in or out on the area in view without the need to move the otoscope, compensating for both the practitioner's vision and variable length of the patient's ear canal.
  • Better clarity and definition of landmarks than a conventional otoscope.
  • The Halogen HPX™ lamp provides light output for true tissue colour and consistent, long-lasting performance.
  • Fibre optics produce a ring of cool light with no reflections or obstructions for glare free viewing and easier examination.
  • Specula ejector for hygeinic touch-free disposal of used speculae.
  • Insufflation port for manipulation of the tympanic membrane.
  • A sealed system for pneumatic otoscopy and accurate diagnosis of otitis media.
  • Variable illumination strength via the handle rheostat dial.

Halogen + Fibre Optics

360° ring of light allows a completely unobstructed view in true tissue colour.

Rheostat Control

Vary the power of illumination with the smooth turn of a dial.


11720 | Coaxial Ophthalmoscope

  • Halogen light for true tissue colour and consistent, long-lasting performance.
  • The coaxial optics produce a shadow-free spotlight, easier entry into undilated pupils and a larger field of view compared to standard ophthalmoscopes.
  • 6 apertures:
    • Micro - allows quick entry into small, undilated pupils.
    • Small - provides excellent view of fundus through an undilated pupil.
    • Large - general examination of the eye through dilated pupil.
    • Fixation - graduated cross-hairs for measuring eccentric fixation or locating lesions.
    • Slit - used to determine levels of lesions and tumors.
    • Cobalt blue - used with flourescein dye to view small lesions, abrasions and foreign objects on the cornea.
  • 2 filters can be used in conjunction with any of the above apertures:
    • Red-Free filter - filters out red light for easy identification of veins, arteries and nerve fibers.
    • Polarising filter - virtually eliminates corneal reflection.
  • 28 focusing lenses with a range of -25 to +40 diopters, adjustable via easy-to-reach maywheel.
  • Rubber brow-rest prevents scratching of eyeglasses.
  • Variable illumination strength via the handle rheostat dial.

Rheostat Control

Vary the power of illumination with the smooth turn of a dial.

Black but don’t worry it is supposed to be. It works!
Size: 1 Liter
This stuff looks like used motor oil but don’t worry that is the molybdenum disulfide (MoS₂) which is black. This stuff in a small engine makes it smooth as silk. I used it all season in my leaf vacuum small engine. I could hear the difference. It was quieter and smoother.

Works just like the Mercedessource guy said it would.
Size: 5 Liter
After viewing a Mercedessource video (trusted Mercedes repair advice Youtuber and blogger) on which oil he liked for higher mileage Mercedes he pointed this out Semi-synthetic 10w-40 out. Called it “muddy” oil. Said it possibly helped with small oil seal leaks and seemed to slow oil loss in higer miles Mercedes. Also made the engines run more quietly. So I have been using in my wife’s high mileage Mercedes (185,000miles W211 2004 E500 4matic) which we baby and I work on. A true very high compression super car, everything he said at Mercedessource has turned out to be accurate. No more leaks. Quiet lifters. Cooler running. Wow. I had been using Mobil 1 full synthetic 0W-40 European Car Formula exclusively but tried this for the seal protection. Works great and no, it is not Mercedes spec but I will see when the harsh Utah winter hits. May switch to the Liqui-Moly 5W-40 Leichtlauf full synthetic (which does meet Mercedes 722.9 oil spec) for winter (I change the oil every 6 months regardless). Thanks for reading.
