Hello Robo-I’ve got the same model-the marks look like smudges-my only suggestion is to try zeiss cleaning wipes-I’ve had a few objectives that I couldn’t get smudge marks of front element until I tried these wipes-picture below-in Australia you can get them in supermarkets.Worth a try as they are p...

Hello peeps-below is a picture of a type of zeiss condenser for variable phase objectives-its looks like it mounts via the top via clamp ring judging from the bottom pic-What size are zeiss ring clamp condensers? 37mm or 39mm or something else?
Regards ross

Thought I better let peeps know about posting for BH-2 Neoplan BD prisms and nose-less than two hours left!

Very cool viktor j Nilsson! The heine looks in very nice condition. Funnily enough I got a second heine just the other day on eBay from Romania-yet to arrive-for my travel scope-it’s got the filter holder and filters-I wonder if it performs best with the frosted filter close to the light entry-do yo...

Greg Howald nice lab! I like how everywhere you turn there’s a different scope to enjoy.. I wish I was neat like that-one day maybe…oh I see you’ve got Mozart’s Gran Partita in your CD collection-and the superb Czechoslovak orchestral version-my favourite. Only kidding! (Not kidding about it being a...

Hey microb did you find this lighting device useful?
Regards ross

Thanks MichealG! I need to loosen the top of a bathtub condenser as well so you helped twice! Much appreciated
Regards ross

Hello peeps-I’ve got a Leitz Berek with .90 top but want to hunt down a 1.4 top-but before I do that I have to work out how to remove the other top-it’s very stuck-I put a bit of isopropyl to see if it would move-no avail but then thought I should get some advice-I got it at a very good price and do...

Hi JeffB -If your not adverse to vintage options from the big four the Leitz SM medical scope is a nice small light scope designed for doctors to carry around in the 50’s 60’s-aluminium stage-the ones with the clever one knob fine/coarse focus are better IMO as they seem very trouble free compared t...

I can confirm that MichealG-I have that cap for the 10x Pv-it seems to only fit in the Pv 10 with the rounder front profile-I’ve got a couple of water dipping WE Pv objectives and the 10x can be used as a water dipper with that immersion cap-it’s a recommended “set” in the heine manual if wanting to...

Hey patta love that spirit of adventure and experimentation! As soon as I read an article about condenserless phase contrast/dark field rheinberg using circles of LED’s I’ve had similar thoughts-just being able to make anulus on the fly and all sorts of color combinations.I wonder if one could use o...

No one would have believed in the last years of the 21st century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narr...

Hey LeonhardEuler That got my attention!-I wonder how expensive they will be! Thanks for posting.
Regards ross

Thanks for the insight Bruce Taylor-Litostomatea sound likely but I’m not sure if it’s shape was more in line with some of the Loxophyllum-are they in the same group somewhere? I seem to remember the head sort of curled over a bit and quite a small mouth (until it became a big mouth!)-I really need ...

Really cool photos AlbertOliver and structurally very interesting-it’s definitely got that “maternity ward” look to it!
Regards ross

Sorry I don’t have video to show-was just doing a quick check on my compost tea brew and I witnessed something bizarre -imagine two ciliates-one orange 🍊 sized and the other cigarette sized-the smaller one latches on the the larger one and it’s mouth just gets bigger and bigger then suddenly most of...

Thanks for all the info guys-the polarising filter may be a good idea if a sample is a bit too shiny (non metallic)-so PeteM you are confirming that later model SM auxiliary lenses can be used as long as they are 48mm thread and you’ve got enough room for working distance? MicroBob I agree about the...

Hi Al-we meet again!-I’ve got one in near mint condition (all bright field)-I’ve also got the CD A 20x version which doesn’t require correction collar (corrected for slide/Petri 1.2mm plus/minus 0.5mm) -The Correction collar versions can be used for DIC-I haven’t noticed much difference with the col...

Nice images—Greg Howald-does XPL mean crossed polariser? Makes the fly mouth part look like darkfield. Oblique is so diverse and I suspect we haven’t seen the last of unique twists to it-I’m fanging to try VAC-need to buy some polarising sheets…
Keep it up

Haven’t seen these in real life yet lagoonatic -any microbe that is mirrored like that is so visually interesting-do these move around or just rely on water movements?
Regards ross

Hey Jimbo I’ve had a similar experience recently-found a nice billabong in the bush and took samples from different areas, some of the clay botttom and algae-finally got to see a volvox-they are cool-also the amoebas adamantly refused to settle on the slide and just continued free forming in mid wat...

Hi linuxusr -I’ve used the technique where you lower objective till it just touches the oil drop on the coverslip then rotate the nose back and forth just slightly to “bump” out air bubbles. I’ve also heard of people using a fine brush to apply oil to front of objective as well as place a drop in no...

Cheers PeteM-so are auxiliary lenses from later SZ scopes compatible or they have to be of the same vintage?
Regards ross
Will have to check out the amscope site-a friend who used to work with forestry told me he’d just thrown out his old micro dissection kit about two days before!-oh well

Tittle says it all-achro 1.25 for Leitz 600 condenser and apl 1.4 for Berek condenser
Regards

Hello-I see they came in four mags-(.5X,.75x,1.5X,2x)- in good condition.
Regards ross

Hi people’s-I’ve got an vintage Olympus SZ-111 coming any day-it’s got the box base with mirror which I’m sure will be handy-two questions-can you do stereo darkfield with this scope and I know they came with optional auxiliary lenses (.5X,.75x,1.5X,2x) extending it’s range-these I suspect will be h...

Greg Howald I call it fabulous!
I’ll have to read up about that one..
Regards ross

There was a few contraptions on the market that did offer this-mainly in 60’s early 70’s-Nikon IPC unit-the almost extinct color Heine-AO polaret and I think another company I can’t think of-I bemoan the lack of this in modern scopes all the time…nice images on the first link
Regards ross

I would say most definitely-pretty common types-the real give away are the oblong shaped ones-at higher mag they have equally spaced markings on both longways edges that make them look a bit like a rulers-but they also come in very interesting shapes and size and move about slowly.

Regards ross

Thanks Bruce Taylor-aren’t they gracefull? Bloody hard to keep in focus but I’m still not good at keeping water drops appropriately small on my wet mounts!
