Your Home Yeast Lab Made Easy - Choosing a Microscope

[@m.e.5925]

Thanks brother. Took a Microscopy course years ago...needed a refresher.

[@juliocbp9389]

This video made me reconsider a purchase I was about to make. Great work.

[@fredrik8549]

Thanks for sharing this information, as a hobby yeast geek. Very easy to follow and apply to my home experiments.

[@Canadiansasquatchbrewery]

Great info. I hadn't thought about a microscope in yeast wrangling, now I want one! Cheers!

[@DanABA]

This is fantastic, Bryan. Thanks so much. I will figure out somewhere to put this on the wiki! :)

[@tube4waldek]

Amazing advice. You’re golden! Thank you.

[@MrButterpantz]

THANK GOD YOU'RE BACK. Quick questions.... I have an older Leica Galen III that is having some stage movement smoothness issues. What do you know of reputable scope repair places? I plan on buying a phase contrast scope in the next year. Used, certainly... most likely ebay. I like lab grade stuff. Makes me happy. Care to put your personal recommendation on solely phase contrast models or a specific feature set/specs to look for? In the future I'd really love to see you do a very indepth review of selective and differential culture media used in brewing.

+MrButterpantz I know of a good local microscope repair facility (a-z microscope), but that doesn't do you much good if you don't live in Ontario. Check your local "yellow pages" - if there is a university or hospital in your community, chances are there will be a company that services scientific equipment. They generally do good work. I am a fan of the Zeiss axiostar line - easy to use, (usually) come with phase1/2/3 optics + darkfield illumination (not useful for yeast counting, but fun with stuff like pond water) and white-light illumination. But anything by the big four - nikon, zeiss, leica and olympus - will be great.

Very informative movies. Thank you for the creation. But what about light source - LED or Halogen is better and if depends, what are pros and cons ?

[@SuiGenerisBrewing]

Doesn't really matter. LEDs last longer and may give better colour reproduction. Halogens are dirt cheap.

[@alexz7111]

Thank you for the explanation and fast response.

[@supyrow]

Excellent information, will come in handy when in the market to buy!

[@gunnarbech]

That hit a spot. Thank you.

[@brisco4072]

Wow, thanks! I've been looking for a video explaining all this for a long time. Very clear very useful as always!

[@hifly1929]

Thank you for providing pictures with you`re video, very educating. Now I actualy know something usefull on how to select a microscope! Well done!

[@SuiGenerisBrewing]

Glad it helped

[@johnhamerlick6711]

Have just found and watched your series on home yeast lab. Thank you, very informative content! I was curious if you have any experience or feedback on the inexpensive usb microscopes currently available. Looking for a possible low budget alternative to even a used quality scope. Thank you for sharing your knowledge.

[@SuiGenerisBrewing]

I have a video on microscopes which may help you decide on one. You do get what you pay for, but am-scope has some good ones for a few hundred bucks. You can often find quality second hand ones as well.

[@GazmendCeno]

Finally, after a long search something Valuable.

[@SuiGenerisBrewing]

thanks!

[@Brew88880]

Another great video! I was waondering which type of oil would you recommend to use for bacterial morpho?

[@SuiGenerisBrewing]

I assume you mean immersion oil? Always use the type recommended by your microscope/lens manufacturer. Lenses are typically made with a specific type of immersion oil in mind, and using something else can lead to poor images or even damage the lens. In case you were not aware, microscope objective oil is a very specific oil, and cannot be replaced with thing slike mineral oil, vegetable oil, automotive oil, etc.

[@rompstar]

great video, which brands do you recommend ? what about Olympus ?

[@SuiGenerisBrewing]

There are a lot of good brands out there. If you can afford one of the big 4 - Nikon, Olympus, Leica or Zeiss - you'll have a scope for life. But these can be very costly. Amscope and a few other brands are beginning to make decent "pro-sumer" type scopes that are much more affordable and should be sufficient for 99% of home and craft brewers.

[@rompstar]

@@SuiGenerisBrewing thanks for feedback!

[@t2i0a1g0o]

Very nice video! Cheers from Brazil!

[@aarntsen]

Is it important to choose an ocular that's monocular or binocular?

[@SuiGenerisBrewing]

There is no technical advantage (resolution, contrast, magnification, etc will be the same). Most people will find a binocular scope more comfortable and easy to use.

[@TonyYates]

This is great information to know! To go beyond general specifications, any chance you could provide specific recommendations for each "Bright field, Condenser, and Phase Contrast" from an easy search on eBay, for example? I find some options on a storefront like stores.ebay.com/MicroscopeNet/. Some with NA1.25, and eye pieces for WF10X/18 and WF25. Based on the optics above 10X, you recommend to avoid such offerrings, and I'm more than willing to take your advice. However, a few recommendations would be nice. :-)

[@SuiGenerisBrewing]

+Tony Yates Its hard for me to make recommendations as I've not used any consumer-grade models, so I cannot comment on any of them specifically. I you have some $$$ a Zeiss Axiostar cannot be beat - its a great intro scope (we use it in all our undergrad microbiology labs), but expect to shell out at least $1500 for a used one. Likewise, any scope from Olympus, Nikon, Leica or Zeiss will be good - but those are all lab-grade and generally pricey.

[@sto2779]

Good info, thanks.

[@jasonclick]
