Question: Would this unit be adequate for testing pond water for: Cryptosporidium, Giardia, E. coli, Poliovirus, etc; to determine if it is a potable source?
Document: As a Ph.D. microbiologist, I am impressed by the quality of this microscope. It has an excellent resolution, almost as good as professional units. To begin with, I was hesitating to order because one of the reviews complained about the intensity of the LED light source. However, this is not true because the microscope has an intensity adjusting knob at the base of the unit, which the reviewer might have not noticed. The LED provides a very intensive lighting.
I have a B.S. in Biology from 1977. I have never used my degree for anything except as a hobby. I have a small goldfish pond about 10 ft X 5 ft. I took a pond water sample and found a couple of protozoan in the slides that I made. A picture of one of them is shown in "customer's pictures" for this microscope here on Amazon. I have only had the microscope for a week but am enjoying it very much so far.
We are homeschoolers and love science so when Biology came up, we decided to buy a nice microscope. I'm so glad we bought this one. The binocular lenses are easy to operate and it's sturdy. The LED is bright and doesn't get hot. I feel like our son will keep this scope the rest of his life. It's definitely perfect for high school and college. We've had a blast looking at all sorts of things: cat hair, threads, foods, pond water, hermit crab exoskeleton and more!
Fit and finish is excellent, the optics are adequate for my purposes although if I had more money to burn I would enjoy seeing through premium glass found on a Leica microscope. But that is a different level of cost.
All other objectives would be ruined if this is used on them. Will have to do more research on this. (10) Documentation was adequate and on-line pdf and videos were useful. (11) Overall satisfaction is very good purchase for the money. Couldn't be more pleased. I've purchased other Chinese optical products and they are definitely up and coming and as 'good' as their Japanese counterparts at a fraction of the cost. Quality Control is subjective at best but overall an excellent value for the money.
Very impressed. Well made and solidly built. Was very easy to put together. Will be using it to do water/wastewater analysis in my lab. Great technical response as well when I had a few questions. One talks to a person!
Easy to adjust, the stage is well designed and the unit is well made for any University or High School scope. It has a good feel to it and is not so large that you need a booster seat. The utube videos are something necessary for the optimal adjustment process. Not sure who wrote the paper instructions. They tried. The vid is better.
The price is truly amazing since years ago I was actually considering investing more than $1,200 for a unit that didn't do as much as this. Packaging was sound, shipping was quick, and the company has followed up to see if I am plesed with their product (how often does that happen?). Highly recommended for science nerds, home schooling or even some serious botanical research.
This microscope is a remarkable value. It's a robust piece of precision equipment. It's a treat to have a binocular microscope. The X/Y knobs for adjusting the position of the stage allows for smooth navigation across the slide. Great light source with dimmer and adjustable iris. Truly a fine instrument.
I was able to diagnose a fungal disease that is afflicting a tree in my yard. (Unfortunately, the prognosis isn't good: it appears to be an infection of Verticillium dahliae. )My only complaint is that the unit shipped to me has a misaligned substage condensor. The manual says that the collimation of this part of the microscope was set at the factory and should not be adjusted by the user. So I've been reluctant to take the condenser out and try to reseat it properly myself.
Answer: No...the lighting and optics are not powerful enough, will certainly do Protozoa, but not much smaller than that.
