Stephanosphaera pluvialis - Aplnaspores and micro-zoospores

Maybe not really spectacular, but maybe interesting for some of the S. pluvialis fans here in the forum after all? Like Haematococcus pluvialis, S. pluvialis also develop permanent stages, so-called aplanospores. In this form, the alga survives longer phases in which the habitat has been dried out. ...

Re: Zeiss Hybrid Eyepieces

Hi 75RR, I could sent you the lower part from the KPL8x for free, the eye lense is scratched so it seems a good coincidense for you. So it would be just the shipment, approx 9 Euro or so. Let me know as soon as you got the KPL 10x. Sometimes difficult to find one of the KPL 10x with an eyelense in g...

Re: Stentor sp. ? and macronucleus troubles

Hi rhiannontries, it looks like your sample has quite a large water layer between coverslip and the specimen. It is nice because it help to observe the natural shape of the beast. However to view and spot the details like the marko nucleus you would need to reduce the water layer, so the coverglass ...

Re: Spring loaded objective

Hi 75RR,
anti clockwise is correct. Sometimes the inner fine thread has anti rotating glue.
I checked my Planapo 63 under the stereo. Yes there is a sealing at the sleeve to the front cone. You would need to break or remove it with a knife, screwdriver etc.

Direction to open is left, like a screw. Unscrewing the rear panel cap using latex gloves, rubber stoppers or leather usually should work. If none of this helps: You need a flat surface for this (e.g. thicker glass plate, metal cube). You stick three on them layers of double-sided adhesive tape on t...
