Description

Features a Siedentopf binocular head that rotates 360 degrees for easy shared use and allows for quick adjustments to the eyepieces for different interpupillary distances without losing focus. The swiveling head can also lock in any position for additional stability. Ocular tubes are tilted at an ergonomic 30 degrees to reduce neck and eye strain. The microscope comes with two interchangeable widefield 10X and 25X glass ocular eyepieces, which pair with the four achromatic DIN objectives -- 4X, 10X, 40X(Spring), and 100X(Spring, Oil) -- in the rotating nosepiece to provide 6 magnification levels between 40X and 2500X. Coarse and fine focusing dials on both sides of the metal arm make fluid and exact precision adjustments. For specimen viewing, an LED bulb beneath the stage transmits light up through an industry-standard Abbe condenser with 1.25 aperture and an iris diaphragm. Manually move the condenser closer to or farther from the stage to adjust brightness and evenness of light as well as image contrast. A metal slide holder locks specimens into place for viewing on the sizeable double-layered mechanical stage. An x-y translational control knob moves the stage and the slide holder left-to-right and front-to-back, eliminating the need to re-clip slides in order to view the entire specimen. The SW350B has a compact but solid body that is nonetheless easily portable with the built-in arm handle. What can you see with it? Compound microscopes offer detailed, cellular-level views of transparent or dyed specimens prepared and mounted on a slide. (For magnifying solid objects, use a stereo microscope.) The SWIFT SW350B is a workhorse of a compound binocular microscope, providing incredibly sharp magnification and ergonomic usability. Designed as a trusty, powerful tool for clinical, laboratory, and educational use, the SW350B is suitable for high school, university, and medical students as well as the seasoned professional. Global leader in the production of quality microscopes for over 95 years. Trusted by educators, researchers and clinicians worldwide. A leader in the design and production of high-quality optics for microscopes, SWIFT has been manufacturing premium yet affordable microscopes since 1926.

  • Pretty good, does what’s expected
Style: SW350B
Bought this on a whim and it’s great. Very easy to use and the kids love it. Now if you’re a nerd and not a kid then you will also find this enjoyable as I have. I recommend buying stronger scopes if you really wanna see what going on 🤓

  • Very Good 'Scope' at This Price Point
Style: SW350B
At a little over $200 this is a gem. Solidly made with lots bells and whistles like adjustable brightness, 360 degree rotating head, 2 sets of eyepieces (10x/25x), parfocal objectives (mostly) etc. It even comes with a couple of polarizing disks you can put over the eyepieces to make a poor man's polarizing microscope. My only niggle is the aperture adjustment for the light is a little flimsy and of limited range. I did not try the oil immersion lens. I'll just add it's amazing how often you can get a good idea of the quality of the product by how carefully it's wrapped. It's perfect for the high-school biology student. My grand-daughter loves it. ... show more

  • An excellent microscope, suitable for both children and adults.
Style: SW350B
This microscope is awesome! My son was so excited to get it for his birthday and hasn't put it down since. The image quality is surprisingly good for the price, and it's really easy to use. We've already looked at everything from onion skin to bugs from the backyard. Highly recommend this for any budding young scientist! ... show more

  • Really easy to use & high quality for the price
Style: SW350B
The title is all my son wants me to say for the review. And he says that the microscope’s quality is high, just not very high comparing to those he uses in the high school. It was a good birthday gift for him, and he’s happy with it. Don’t buy those kids ones that are usually under $50 or under $100, those are basically junks.. trust me, we’ve used two of them. They come with many tools, slides, etc. But the microscope itself sucks, we could barely see anything well. ... show more

  • Works great and good customer care !
Style: SW350B
I was excited when this microscope arrived. But unfortunately when I opened it and plug it in the light never turn on. So disappointed. Update : The company contacted me and kindly sent me a new one, the light works fine, yay! Now that I tried it I could say that this is a good quality microscope , easy to use , with clear and wide lens that are easy to focus. I really like it and can’t wait to look at more things and explore. I attached some photos I took using the microscope. ... show more

  • Great Objectives Well Built and Overall Great
Style: SW350B
I’ve gone on 6 hour round trips to the ocean and everywhere in between to see all sorts of organisms, great for modifications and improvements. Solid interior prevents damage to the lighting components, the adjustment knobs are smooth and operate well, as well as the mechanical stage, comes with a bag and oil, overall great microscope with a relatively affordable price, fluorescent objectives cost more than the microscope lol ... show more
