Zeiss Model AxioSkop-40
HBO 100W Mercury
Manual Operation
Upright Fluorescence Microscope
Low Sale Price

USD $6,500

Model: Zeiss AxioSkop-40
Shipping Cost: Free USA Shipping.

Main Features:

  • Completely manual operation. This is not the version that is all motorized. Consequently, there are less things to go wrong with this frame.
  • Configured for Brightfield and Fluorescence.
  • Condenser Numerical Aperature 0.9.
  • XY right-hand mechanical stage with slide movement fingers.
  • Camera not included.


Incident Light – Fluorescence Illumination:

  • HBO 100 power supply. Note: this power supply works just fine and the lamp housing produces an excellent illumination with the included lamp housing. However, the LCD screen for the hours-meter does not work. This is not really needed anyway since the bulb periodically should be checked for fouling, cloudiness and darkness and replaced if found to have such.
  • Aperature Diaphragm with centering.
  • Luminous Field Diaphragm with centering.
  • IR cut-off filter to block damaging IR radiation.


Transmitted Illumination:

  • 12V-100W halogen transmitted illumination.
  • Includes built-in diffusion disk lever to engage/disengage.
  • Does not come with any ND neutral density filters.  It has spaces for them but filters are not included.


Objective Lens and Nosepiece:

  • Six place objective nosepiece with the following lenses:
  • A-Plan 5x / 0.12, Infinity/–.
  • Achroplan 20x / 0.45, Infinity/0.17.
  • A-Plan 40x / 0.65, Infinity/0.17.
  • Achrostigmat 100x / 1.25 Infinity/0.17. Oil Immersion.


Dichroic Fluorescence Filter Cubes: 

  • Five – place cube turret.  Includes quantity 4 light blocker shields.
  • FITC – EGFP filter cube in good shape.
  • This microscope was tested with this cube and it produced excellent quality florescence imaging.



  • Trinocular photography port on top of the head.
  • 100 Percent – 0 Percent: Selector pull knob.
  • Includes 1x c-mount camera adapter.
  • Does not include camera. Camera is only shown to demonstrate how one can be connected.

  • Note: The frame and the lamp housing have some insignificant paint chips and paint imperfections. We did some touch-up painting.



  • This is a high quality Zeiss optical instrument.
  • We also sell Chinese made fluorescence microscopes but the quality is substantially lower.


Testing Results:

  • This microscope was fully tested.  Results are as follows:
  • All functions were found to be in proper working order.
  • Brightfield – Koehler illumination was set properly, with all adjustments and centering being properly achieved.
  • Incident Reflected Fluorescence – HBO Bulb was properly centered obtaining bright, clear, and uniform illumination distribution across the complete field of view.
  • Fluorescing Capability – Obtained bright and clear images.


Optional Accessories:

  • We have a wide variety of optional scientific cameras, both monochrome and color, with and without Peltier cooling.
  • Other objectives may be added.
  • Brand new Chroma hard coated filter cubes with lifetime warranty may be added.  Cost is USD $750/set for the dichroic filter (emission filter, dichroic mirror, barrier filter) and blank cube.

One Year Parts and Labor Warranty:
We warrant this Microscope to be free from defects due to normal usage in normal operating conditions for a period of one year. Camera equipment (if included) is given a three month warranty. Objective lenses are excluded from warranty.
Additional warranty on microscope may be purchased if desired.

We will repair or replace equipment at no charge, during the one year warranty period. Both parts and labor are included. Buyer is responsible for shipping costs BOTH ways, paying for shipping cost to our designated repair facility and shipping cost back to buyer. Bulbs are considered user replaceable items and not covered.

Warranty Excludes Objective Lenses:
Our warranty excludes the objective lenses. There are several reasons for this. First of all, if the objective is good, it will continue good performance unless there is some user or environmental abuse. Abuse can be from oil getting on a non-oil immersion lens, contact with a solution that degrades the cement around the glass, contact with other chemicals that may stain, etch or pit the glass, scratching the lens by incorrect cleaning methods such as cloths not of lens cleaning quality, damaging the lens by scraping it on slides or metal slide holders on the stage, dropping on a hard surface, subjecting the objective to extreme humidity causing internal mold or mildew, etc.
In addition, objectives can’t feasibly be repaired. If an objective is damaged so that the optical quality is significantly diminished, it is suggested to throw it away. One solution is to send it back to the factory and incur a repair fee equal to about half the price of a new replacement. That is usually cost prohibitive. We professionally clean the front and back lens, and the outside barrel of the objective. But we do not open them up. That should only be done by the factory under strict conditions and with optical laser alignment. Generally, when someone other than the factory messes with a lens, the performance may still be acceptable, but likely will be noticeably lower quality when compared side by side with a new lens. So since defective objectives are generally thrown away, and replaced with another one, there is no need to warranty them. The user can easily find a matching objective and replace it on their own.

Objective Lenses – Condition:
All objectives have been professionally cleaned.
All are guaranteed to be free from optical defects. If any defect is found, it will be clearly noted in the ad.
Our inspection of the objective lenses includes checking for the following:
lens cracking, pitting, lens cement not intact, internal oil damage or oil seepage, glass fogging, glass hazing, stains on optical glass, mold or mildew stains, and delamination (separation of internal lenses).

Condition of Equipment:
This reconditioned microscope is complete and in excellent working order and has been completely checked out and serviced.

Technical Sales and Support:
Most offerings of used microscopes are by simple flippers of equipment who have obtained defective and rejected microscopes from labs discarding the equipment. They resell exactly what they got, as they got it, and without any technical knowledge of it. You can rest assured when purchasing from us that we are professional dealers who are well trained to service and provide technical support of the microscopy equipment. We test, repair and refurbish all equipment to excellent working conditions. We are well trained and able to give you technical advice including pre-sale and post-sale support.

Free Application Evaluation and Recommendation:
We strongly encourage all potential buyers to first contact us with regards to their specific application. In most situations, we need to customize certain features of the microscope in order to best fit the end user’s technical requirements. We want to ensure you have the correct and optimal configuration for your application.

Fluorescence Filter Sets – Customized:
We are dealers of both Chroma and Omega brands (Made in USA) of dichroic filters. Please contact us regarding the specific fluorophores you are using so we can be sure the filter sets provided are a proper match. Incorrect matching will give you poor quality or no visible fluorescing.
