Re: New Carl Zeiss Standard RA38.

Had a lab bench power supply, tried it. The bulb seems broken. Do you know of some disassembly instructions to try to get to the bulb ? What would you recommend to do for the illumination ? I suggest you find a way to light up that bulb, I think it is 6V and 15W, check somewhere. Lab power supply mi...

Re: New Carl Zeiss Standard RA38.

The eyepieces seem functional and do produce a binocular image, can I just use some cheap WF10X objectives from amazon or should I try to find some zeiss ones for replacement, is the difference going to be huge ? Rn my biggest trouble is the illumination as the bulb seems to be broken, would you rec...

Re: New Carl Zeiss Standard RA38.

I just tried to power the bulb with a lab bench power supply and nothing, on closer inspection I found the filament at the bottom, might have happened during shipping for earlier during use. Are replacement bulbs easy to find ? If not what kind of illumination setup should I be looking at. also woul...

Re: New Carl Zeiss Standard RA38.

Understood. Yes sorry my bad it is a 40X PH. Nothing apart from the smallest condenser PH stops seem to be delaminated. Can this still be functional or I need to swap it out if I want to use it ? I posted some photos of the illuminator. If the microscope is mechanically sound and smooth, that is tru...

Re: New Carl Zeiss Standard RA38.

Thank you so much, is using alcohol alright ? Do the lenses have coatings that can be eroded by the alcohol ? You are absolutely correct about me wanting everything right away :P I ordered some ATE Plastilube to try to use during some cleanup. Thanks !! Can you recommend some cleaning/ servicing sup...

Re: New Carl Zeiss Standard RA38.

Hi guys, a huge thanks to everybody for the great resources and all the information. The microscope finally showed up, good and bad news: There were some cosmetic damage that was incurred during shipping, the base plate broke off a piece (I wonder how that happens) and the power connector had some p...

Re: New Carl Zeiss Standard RA38.

Re: New Carl Zeiss Standard RA38.

@PeteM Actually I am still waiting for the scope to be delivered but hoping that these are indeed Carl Zeiss ones. Will update once I get it. Is the ideal eyepiece config KPL 10X, I understand that the KPL are a must with corrective optics ? Just out of curiosity I saw from the Zeiss manual at http:...

New Carl Zeiss Standard RA38.

Just got this microscope for 250 Pounds, was kind of an impulse decision so hoping it was a good deal. I basically could not find any documentation on it or know anything about its general upgradability, I understand it can do brightfield and phase contrast but that's about it. Would really apprecia...
