Re: Dancing worms in on of my pond tanks

I love those little guys. A tiny little vibration and they hide though. I have found them to be somewhat seasonal if you leave them near an exterior window.

AO 120 Binocular prism repair

I just recently picked up a nice AO 120, complete with the external lamp housing, the lamp socket, filters, transformer, and binocular head. Oh, and the 180 eye pieces. For $80 I think it was a bit of a steal. Anyway, I am not sure if it was in the shipping during cold weather or the reason the scop...

Re: can i wash and reuse bacterial heat set slides?

For high school, I would say use a mix of vinegar and original formula dawn dish detergent. When I ran a microbiology and mycology lab, we would put slides in a 2 liter container with the vinegar/dawn mix and let it sit until full. We then cleaned them all and let them dry. The stronger the acetic a...

AO MicroStar 120

I am trying to get a hold of the series 120 manual. I have the 110 and vertical illumination 110/120 but cannot seem to find a 120 manual.

AO beam splitter/vertical illuminator

I was thinking of bidding on this eBay item number 153667503727. It is an AO 1111-3 beam splitter/vertical illuminator. However, it looks like it might have a damaged lens in one of the photos and I don’t know the light you would use for the vertical illumination. Any ideas guys.

You can read the field guide to bacteria for help on what can be useful when dealing with bacteria. I have a lot of experience in teaching undergraduate microbiology labs.

No, it does. There was a paper published on it. If I can find it again I will post a link. I refuse to stop using it. I mean I’ve had to regularly work with KCN and NaCN. If I can protect myself from exposure to those I think I can for EtBr as well.

Re: Disposing of stains from home microscopy lab

Oxidizing can produce even worse chemicals. For instance, bleach and ethidium bromide makes much worse chemicals than ethidium bromide. California actually allows 9 ng/L of ethidium bromide in the normal sewer system in some cities. I doubt you produce enough to cause any harm however you dispose of...

Re: First Surface Mirror?

There are two types of hard drive disks. Some are made of aluminum and others are made of ceramic. Seems most people that cut them use a jewelers saw and some sort of cutting fluid I believe. Maybe some day I will give making a DIY water jet cutter. I know it has been done.

Re: Relief Phase Contrast Microscopy - Article by Prof J. Piper in Microscopy and Analysis, vol 21, 2007.

I have ended up with two turret condenser bodies for my AO series 10 and 20 microscope. Once I get them both in working order (need another trinocular and series 20 lamp cord and socket) I will try to create a much more controlled test of this “relief phase contrast”.
