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…
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…
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…
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…
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…
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…
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…
Hi Andy, The Wilkinson Power Divider/Combiner is a primary component in the adding (or subtracting) and phase switched interferometers. It combines the signals (and noise) from two antennas and implements…
Yes. The cheaper plan you’re seeing is ChatGPT Go. OpenAI currently lists Go at $8/month in the US, with localized pricing in some countries—which is presumably why you’re seeing about…
I stood on a chair in front of 40 foot RT and got on and off the chair and it showed up on the old-style pen and paper recorder used…
