Lab temp range

What is a realistic temp range for my three scopes? They are stored in the
house, which is 66 to 73 deg. l have not had much time to learn how to
stabilize the lab temp, which has a small wall heater, and a thermostat controlled
ceiling vent.

Re: Sealable glass sample cuvette for portable inverted scopes or low power field use

I did not plan on a cap. Once I have one built I'll post pictures. The purpose is for
high volume scanning with the inverted, but I really want to get up to speed with
the diatom processing, There is this awesome thread here..............

Re: Sealable glass sample cuvette for portable inverted scopes or low power field use

I invested in glass, and glass cutter, and will try to fabricate my own, but thanks
for thinking of me. My new lab only needs flooring and an 8' desk mounted, but I
don't get the new house keys for a few days.

Re: Doing Diatoms

Those beautiful rings! Could I use the same enamel to build up a perimeter
dam to create a very small rectangular well slide? 2mm thickness.

Re: Tylenol

My setup would be like yours, except the Nikon has a nice slit between the head
and body that will accept a fairly thick sheet of polarfilm. There is such a wide
variety of these films I'm hoping to avoid a costly mistake!

Is there a 'best' polarfilm ? Brand, thickness, or any special quality? It
will be paired with a camera lens polarizer.

Re: How useful are objectives with corrective collars?

The petri dishes were ok til I added the mechanical stage, now I want to fabricate rectangular
slides with sides. Like a big well slide. I can't free hand a petri dish on high power.

Re: How useful are objectives with corrective collars?

Apo, when viewing through the bottom of a flask with an inverted scope, that is when
longitudinal spherical abberation would benefit from the collars correction?

Re: How useful are objectives with corrective collars?

I suppose you could think of the bottom of a petri dish as being a coverslip. I have long working distance objectives with collars on my inverted scope. Here's looking up atcha!

Re: Doing Diatoms

Rod, picture #4, if I took a tiny sample from just above the sand would it give any hint as to its content? All the sand I collected from Ocean Shores has dried out. Should I toss it? Sort of in a bind as all my stuff is already packed for the move, but the Nikon and a well slide are accessible. Dale
