Re: Does anyone else have this sample collecting problem?

I have successfully used a long stick as a guide for a small rubber hose that has a 50ml syringe on my end. Once you select a sampling spot simply dip the stick with the hose firmly attached to it with pig tails or whatever and slowly pull the plunger on the syringe. Then discharge in your sample co...

Re: The Art of Fluorescence Microscopy (DAPI filter)

Cool but can you actually buy some DAPI? You could then see the DNA inside microorganisms for example the different nuclei in ciliates.

Thanks Jan and you are right the movement looks unnatural but some of those critters are bullet fast. Not only I can't shoot them I can't see them for more than a second in one place under normal conditions.

Is it slowed down, or in glycerin or something? I've never seen cilia move like that before.
Yes, it was slowed down with methylcellulose, video is at normal speed tho.

Thanks 75'

The ciliate video was taken with a 40x phase objective at 2x optovar magnification so a total of 800x, but thats the highest I went.

A few recent findings

I didn't feel like making individual threads for these microbe findings of the past couple of weeks so enjoy the video dump

Diatoms, a fast amoeba, worm on LSD and an unidentified ciliate.

Re: Emotional Attatchment To Microbes

Its basically a container, like a petri dish, with some wet tissue (e.g. moist napkin). When the humidity reaches 100% it means the air can't hold more water vapour because its saturated and therefore the water in your sample cannot evaporate. Now if you don't want to observe your microbes later but...

Put the slide in a humidity chamber. Not only you save your beloved microbes but they can actually develop on the slide providing you with more insight on your next observation.

I suppose salts from the soil would counteract that.

Freshwater Dinoflagellates



I somehow always thought dinoflagellates are restricted to marine habitats so was quite surprised to find such an abundance of them yesterday. This new pond I sampled is crazy full of life, it has everything from freely floating rotifer colonies to Volvox to gigantic red mites.

You know you can insert a piece of clear plastic above the polarizer and below the specimen and you will produce some spectacular colors that would enhance the starch grains.
