Re: Cover slip container

I bought one of these about 4 years ago and have been living happily ever after. https://tinyurl.com/yxrhnvpu Seriously, it's so great I ordered a second one for backup, haven't needed it yet, and I makes lots of slides. This baby makes picking up cover slips fun! In case the URL doesn't work: eBay...

Re: Hi from South Africa

Hi I recently got my first microscopes. A Carl Zeiss standard with an epi fluorescence attachment and a Nikon optiphot with phase contrast condenser. I picked them up for quite a good deal but they have been standing open in an warehouse for at least the last two years so need a really good clean a...

Re: First Stain, and mounting

I have stained onion skin with several different dyes, but not Eosin. If time permits, I can try it, within a week or two. I bought lactic acid at a local pharmacy, that specializes in "original" lotions and creams based on natural ingredients. A few ml, for a few $$. Lactic acid is a slightly syru...

Re: First Stain, and mounting

Hello, Just did my first stain and mount. I carefully dissected an onion, removing a very thin peel of skin from the inside of the onion. Got it laid out on the slide, placed a small drop of water on it, then carefully put the cover slip on, by lowering it, starting at a 45 degree angle, and using ...

Re: First Stain, and mounting

1. Is it normal to have the cover slip rock? The slides I used were beveled edge flat slides. 2. Is there a way to get the stain to penetrate into intact cells? 3. Once finished I assume I clean and reuse both the slide and cover slip? 4. I noticed that the stage movement controls on the Microscope...

Re: My new Microscope

I have two questions regarding my new Microscope: 1. On the condenser, the section the filter ring is mounted on, and which also has the diagram control, rotates freely, is this as it should be, or should it be non rotating? 2. Are all microscope eyepiece tubes the same ID? I am thinking of getting ...

Re: My new Microscope

Nice fresh looking microscope. 1 micron fine focus, all metal. Very fine. Grey, like the Kyowas although many of the Bristoline were a very attractive moss green. That is a sleeve for the key. Other as noted is a screwdriver. I see the cord for the key attached to the carry handle, which would have...

Re: My new Microscope

Congrats! That's a pretty scope. The two items you found in the box: the plastic sheath is a cover for the box key. The metal triangular thing - if not an odd shaped key - is probably a screwdriver of sorts. Microscopes are often held in by a screw or bolt coming up through the bottom of the case. ...

Re: My new Microscope

Congratulations on having this pretty microscope. Previous threads in this forum (search for "Bristoline") indicate that it is a good starter scope. As an alternative to a smartphone camera, you might consider an inexpensive (~70 USD and below) 5MP USB eyepiece camera, that comes with a 0.3X-0.5X r...

Thank you! I was quite pleased with it... I will probably get an insertable camera of some sort, and use one tube for viewing, and one for photography.

Hi, Name is Dave, and I am new... Was asked to shoot a few photos of my new Microscope, so here they are... First decent Microscope I have owned... Picked it up at a Ham Radio convention. There is some sort of simi sharpened metal device in one of the photos. If anyone knows what this is, I would be...

Re: New Microscope...

Welcome to the forum and you found a good microscope. Bristoline of that vintage were made by Kyowa and they were a very underrated microscope at the time. The optics, especially in the area of contrast were very good for their day and they also had very good mechanical build quality. Kyowa did a l...

New Microscope...

Hello from Oregon, Just got my first decent Microscope at a Ham Radio event of all places... An older Bristoline 3000, in mint condition. Four objectives, one oil. I have never had a decent microscope, so this should be a fun adventure. Been viewing all the videos our host provides, (thanks), and or...
