Upright Compound Epi-fluorescence Microscope

BX-51-F:  $12,967.57
For high-resolution imaging and fluoresence, the upright compound microscope, with its high numerical aperture condenser and objectives, is great. Now you can get a top-quality research-grade compound upright fluorescence stereo photo microscope for a fraction of what you may have thought — with two or more filter cubes, such as GFP/Fluorescein(FITC), Rhodamine(TRITC), or DAPI/Hoechst filter cubes included!

Finally there is a great alternative to the traditional route of dealing with your local "traveling salesperson" from Nikon, Olympus, Zeiss or Leica.  These companies generally make very good products, but not only do you pay a premium for their microscopes, you also pay for the salesperson, the saleperson's family, the saleperson's car, the saleperson's bonus, etc.  And, you'll pay for every single item, a la carte, at top dollar... right down to the the power cord! After they make it all add up to $20k-$30k, they try to make you feel better with a 5-10% discount.

Wouldn't it be better to pay half the price, without even asking for a discount? When you order our microscope, you pay for the equipment, not the international marketing program and sales force.  We configure the microscope with exactly the options you need, set it up, test every function with real samples, and then ship it to you.  Within minutes of opening the box, you're ready to use the scope!  And we're here nearly 24/7 to answer any questions you may have... for free... forever.  Try getting a quick response like that after placing an order w/ a local "rep"!

  • Please note that the price above is for a basic functional configuration with a few Plan Fluor objectives. Your BX-51-F will be customized according to your needs and we'll prepare a quote for you so that you can see how various options affect the price. For example, objective lenses range in price from a few hundred dollars to a few thousand dollars each and filter cubes are about $1000 each. The microscope can hold 4 cubes at one time, or 3 cubes and a blank.


    Q: Can this system be equipped with DIC optics?
    A: The BX-51-F doesn't have positions for the DIC polarizers, so it would be hard to set it up for DIC. However, Phase contrast, or a more DIC-like view from Hoffman contrast are possible. Of course none of these contrast methods affect the fluorescence image.

    Q: Can the system be used to acquire publication-grade images if a CCD camera is added to it?
    A: Yes, it can absolutely capture publication-grade images. It can be used with any c-mount camera (we have various c-mount adapters to match the sensor-chip size of different c-mount cameras). We have some good options in the $1000-$2000 range for low-light image capture, but you can use a c-mount camera that you get anywhere else, too.

    Q: Can the BX-51-F be equipped w/ 4 filter cubes instead of 3?
    A: The microscope can be ordered with as many cubes as you like. The cube-slider has 4 positions, so you can put up to 4 cubes in at one time. However, if you use all four, then there will not be a "brightfield" position with no emission filter. The price shown on our website is an approximate system price. If you're interested, we can go through the various options of objectives, condensers, cubes, and cameras and then give you a formal quote.

    Q: We are currently trying to align a new UV bulb in our BX-51 fluorescent scope. We get the 2 focused blue points on a sheet of paper on the stage. However, when we open the shutter we do not get even illumination and this weird triangle.
    A: In addition to the X and Y position adjustment knobs that allow you to move the bulb, there are also some "screws" on the back side of the lamp holder that allow you to adjust the position of a reflector that aims the light going toward the back forward, toward the sample. If this is out of alignment, you will get a 2nd spot. You might want to take out the lamp holding side panel and make sure you are happy with the position of the bubble of the bulb being centered and the bulb itself being parallel with the back of the lamphouse. The bulb is held by a thin strip of metal and it might have bent when changing the bulb. If that doesn't fix it, then use the hexagonal tool to adjust the mirror angle to get the reflection spot to converge with the direct spot.
