Main Features:

  • Tilt back upper light carrier. Ability to tilt out of the way to access large culture vessels or optional micromanipulation equipment.
  • Stage has XY slider with a universal mounting plate capable of handling petri dishes or a typical 1×3” glass slide.
  • Side camera photography port. This has ability to take 100 percent light to eyepieces or split 20 percent eyepieces and 80 percent camera port.
  • Binocular Viewing Head.
  • Eyepiece pair is W-Pl 10x/23 guaranteed for usage with eyeglasses or without.
  • The 23mm is a great field of view. Both eyepieces have focusing diopters.
  • Rubber cupping eyeguards blocks ambient light from the room when viewing through the head.
  • Shutter with ability to block light from entering eyepieces when taking photos.
  • This prevents inadvertent ambient light exposure on camera.
  • Six Place Objective Nosepiece. With DIC slots in each position.
  • Two lifting handles to make it easier to move this large and heavy duty instrument. Often times these are missing.

  • RHOD / R-Phyco (Rhodamine, ex. 546/12, moderate wear).

Zeiss Tool Kit:

  • Includes the original Zeiss supplied tools. Made in Germany. These include the needed screwdrivers and spanner wrenches, etc, as noted in the user manual.


  • This microscope is in great condition.

Research Grade Applications:

  • This industry-standard optical instrument is used for observing intracellular processes in living cell cultures, motility and growth, cell to cell interaction, and drug detection. With optional hardware equipment and software, it can also do micromanipulation and microinjection, IVF in-vitro fertilization, patch-clamp technique, toxicity examinations, time lapse examinations, and ion measurements. It can also be useful for z-sectioning, Fura (Ca measurement), deconvolution, GFP, and single molecule detection. This is a high grade research model and is capable of being adapted to all of the above, given the right optional equipment.


  • This is a high quality Zeiss (Made in Germany) optical instrument. We also sell Chinese made fluorescence microscopes but the quality is substantially lower. We highly discourage buying the Chinese microscopes due to the problems that incur after the sale.

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.
  • Phase Contrast – All objectives performed well under phase. Images achieved were good.
  • Incident Reflected Fluorescence – HBO Bulb was properly centered obtaining bright, clear, and uniform illumination distribution across the complete field of view.

Fluorescing Achieved –

  • 40x objective – Obtained extra good image.
  • 20x objective – Obtained good image.
  • 10x objective – Obtained good image.
  • 4x objective – Obtained poor image as expected. A 4x seldom gives good fluor image as too large field of view. Fluor signals are very tiny spots at 4x.


  • 40x objective – Obtained extra good image.
  • 20x objective – Obtained extra good image.
  • 10x objective – Obtained good image.
  • 4x objective – Obtained poor image as expected.


  • 40x objective – Obtained good image.
  • 20x objective – Obtained fair image.
  • 10x objective – Obtained fair image.
  • 4x objective – Obtained poor image as expected.

Optional Accessories:

  • We have a wide variety of optional scientific cameras, both monochrome and color, with and without Peltier cooling.
  • Other stage mounting plates available.
  • DIC differential interference contrast is possible on this frame. Contact us for details about how to add this technique.
  • Other objectives can be configured.
  • We can provide brand new replacement 100W HBO Mercury Bulbs and Halogen bulbs.
  • 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 includes the blank cube.

Fair Market Value – Discount Price:

  • Fair Market Value USD $15,000.00.
  • Discount Price USD $12,500.00.
  • We did not find any complete comparable models for sale by others.
  • We found some at $13,000, $25,000, and $36,000. They all had obsolete parts and will need new parts to make them functional. We found another at $12,000 but it was missing fluorescence cubes, power supply, and had an obsolete stage that would require buying a new $2000 stage.
  • We found another at $19,000 that was missing stage controller, lamp housing, power supply, etc.
  • These systems were all obviously something being sold exactly as the seller received it, and shipped to you without any testing or modifications. They are not configured or set up to run.
  • In addition, we are including a one year warranty, money back guarantee, and free shipping that are value added additions not given by most resellers and should be added to the value.

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.
