What is the frequency for 22ghz water masers?
Admin
For the 22 GHz water maser (H₂O) line, the laboratory rest frequency is approximately: 22.23508 GHz = 22,235.08 MHz Astronomical maser emission is Doppler shifted by the motion of the…

Zeiss IM35 microscope fluorescent cubes – suggestions for microscopy at LRO
ADVICE FROM CHATGPT: The Zeiss IM35 was originally designed to accept interchangeable fluorescence reflector/filter blocks, and I’ve found period evidence for several combinations actually used with the IM35. The most…

What fluorescent dyes are good choices for my Zeiss IM35 inverted microscope?
Yes. The Zeiss IM35 can make a very capable fluorescence microscope, but the best dyes depend primarily on the fluorescence filter sets fitted to your particular IM35, rather than on…
What else beside scales would be useful for preparing fluorescent microscopy stains such as FDA?
For preparing small quantities of fluorescein diacetate (FDA), I’d get a few inexpensive laboratory consumables. You don’t need elaborate equipment. For your particular setup, I’d start with micro-spatula + weighing…
What is a good choice for laboratory scales for microscopy?
Yes — a good used laboratory balance from eBay can be an excellent choice, particularly compared with inexpensive new “milligram” pocket scales. For weighing 50 mg (0.050 g) of fluorescein…
Most appropriate fluorescent stain when aim is to stain particular structures in cells.
Certainly. If you’re experimenting with fluorescence microscopy, I’d choose the stain according to what you want to see rather than buying fluorescein disodium first. What you want to examine Good…
How do you check rubidium source gets rubidium lock?
For a rubidium frequency standard, there are usually two separate things to check: On most rubidium modules, the best indication is a dedicated LOCK / UNLOCK / STATUS output. After…
How to set manual focus on the Olympus OM5 four-thirds camera
On the Olympus/OM System OM-5 you can set it to manual focus (MF). The simplest way: You can also make manual focusing much easier by enabling Focus Peaking, which highlights…
How to set exposure compensation on Olympus OM5 camera
It’s called exposure compensation. For example: On your OM-5, you’ll normally see it displayed as ± EV, with a scale such as –3 … 0 … +3. If you’re trying…
