# 1 Best-Selling Microscope!

From the multi-awarded My First Lab microscope series comes the MFL Duo-Scope, Winner of The Top Toy Award by Creative Child Magazine and Still the # 1 Best Selling Microscope; specially designed and developed to allow young scientists, ages nine and over, to examine specimens such as Blood Cells or Organ Tissue on real microscope slides, as well as view small solid objects like Plants, Coins and Insects. With its Dual cool LED illumination, the Duo-Scope is two microscopes in one, in that it can function as either a compound microscope, with the light shining up from underneath, for viewing microscope slides, or it can function as a dissecting stereo microscope, where the light shines down from above, for use when observing solid objects. The Duo-Scope assures that everyone will be amazed by the detail in the magnified images they will now be able to see.

A Real Biological Microscope!

The Duo-Scope is an authentic, scientist-grade, biological microscope and is not to be confused with TOYS, which claim to offer higher magnifications but are unable offer CLARITY. The Duo-Scope uses real optical glass lenses that have been specially crafted to provide the user with crystal-clear 40x, 100x, and 400x magnification, to view slides or solid objects through a 10x eyepiece, which also functions as a magnifying glass when removed from the eyepiece tube and turned over.

Designed for Maximum Portability!

Designed for maximum portability, the Duo-Scope features an impact-resistant frame and is AA battery powered, so whether examining the surface of a coin in the attic, studying a tiny insect's hairy legs in the garage, or checking out different rocks and leaves in the yard, the Duo-Scope is the ideal companion for venturing out into the Exciting World of Science.

Frequently Asked Questions:

Q – I SAW ANOTHER MICROSCOPE WITH 1600X MAGNIFICATION. IS THAT MICROECSPE BETTER BECAUSE IT OFFERS ME A HIGHER MAGNIFICATION? A – Not exactly. A higher magnification does not always translate into a better microscope since clarity is the most important attribute to consider. At 1000X magnification, OIL between the objective and lens is sometimes required in order to achieve better clarity. We have carefully selected a range of magnification that will be easily viewed by our young scientists to avoid frustration when making adjustments to higher magnifications. Q – CAN THE DUO SCOPE BE USED FOR REAL-LIFE EDUCATIONAL APPLICATIONS, LIKE SCHOOL PROJECTS? A – Absolutely Yes! , the Duo-Scope is an authentic laboratory-grade scientific tool that will accompany the user all through their high-school education.Q – HOW DO I KNOW WHAT MICROSCOPE TO BUY? A - The type of microscope to buy depends on your intended application, because basically, STEREO MICROSCOPES, Offer lower magnification and are primarily intended for applications that require you to “work” in a magnified work-space and provide you with the ability to view specimens that do not fit on a microscope slide. A compound microscope offers higher magnification and is used to view specimen so small that it needs to be mounted on a slide. DUO-SCOPES are dual functioning microscopes that can do a little of both! Q – I SAW A CHEAPER MICROSCOPE. WHAT MAKES THIS ONE BETTER? A - We only use glass optics. Buying a microscope with plastic optics is like comparing looking through a clean window and a dirty window. Even if you do not buy our microscope we recommend you buy a microscope with glass optics Q – HOW DO I KNOW IF I AM ON THE RIGHT MAGNIFICATION? A – Magnification is determined by multiplying the power of the eyepiece, with the power of the objective. The Duo-Scope features a 10x eyepiece, a 4x objective, a 10x objective and a 40X objective, thus providing the used with a range of 40x to 400x magnification. Q – HOW DO I KNOW HOW MUCH MAGNIFICATION I NEED? A – The amount of magnification needed depends on your intended application, the specimen type. See the chart below: A.1 - 10x to 40x is the ideal magnification range for viewing Insects, jewelry, keys, and even small toys. A.2 - At 40x to 100x magnification, cells and organ tissue are now visible, as well as some smaller solid items. A.3 - 100x to 400x magnification is the most frequently used magnification range for general laboratory applications and offers higher definition images of blood cells and organ tissue and nerves.

As a physician, I have a great deal of experience with microscopes. The optics on this scope are quite good for the price, and although some parts of the scope are of cheaper quality(such as the battery compartment), they put the money where it counts. Intuitive design, and surprising illumination at high magnification(400x). As a bonus, this scope also features above-stage illumination, which allows examination of opaque objects such as insects- making the scope easier to use for younger kids who cannot prepare traditional slides. Finally, included supplies such as dust cover(!), scalpel, probe, prepared slides, well slide, stain, cover glasses,small petri dish, lens paper and test tube allow the budding scientist to set up a home "lab". Excellent for ages 8-13

Let's cut to the chase: If you're looking for an inexpensive microscope for younger children, the Duo-Scope would be very difficult to beat for features, quality, and cost.

After reviewing several sources on inexpensive microscopes, I took a chance for Christmas on this less documented model. I'm glad I did.


* Solid construction. Despite its light weight, it feels like a coherent whole and has no rattling pieces. The objective lenses click nicely into place and the mechanics have a silky feel when operated. This model considerably betters the microscope I had as a child growing up in the Sixties, so some items ARE better made today than yesteryear.

* Smooth focusing wheels that don't clunk through the mechanism's gearing.

* Permanent, bright light sources from two separate LED bulbs. Far better than mirrored scopes.

* A pointer in the optic field--a nice addition to a low cost scope.

* A plethora of accessories including four prepared slides, six blank slides (including concave/well), slide covers, stains, tweezers, scalpel, lens wipes, vinyl dust cover, and more--just about anything you would need to get started on a basic level (except for three AA batteries).

* A detailed manual of a higher quality than most will expect, especially considering the microscope's country of origin.


* Made in China.

* The upper and lower lights cannot both be turned on at the same time for maximum illumination of semi-translucent objects.

* When using the highest power objective, the optic field is still too dim.

I bought one of these for my 10 year old. I was very pleased with this purchase. This microscope is well made, durable, and contains quality optics. It is as good of a microscope as you would find in a high school lab. With the upper light you can zoom in on coins, seeds, etc. with clarity. It makes a perfect birthday gift.

After receiving a 28-piece microscope kit for Christmas that had a plastic scope that broke within 5 minutes, we were in a dilemma: Our son decided he really wanted a microscope, but we didn't want to get burned again. After much research, a science teacher at my school said she bought this for her child. She said the quality was great and that it does things some of the scopes in her high school lab didn't do. We bought it for our son's birthday and it's a huge hit! It is made of very durable materials, is easy to use, and is an extremely high quality for the price. My sons are 7 and 9 and we've had a blast with it! The fact that it's a duo allows you to view slides and objects they pick up around the house. The were amazed when we put different types of print under it to see the difference. I bought a book that Amazon recommended to go with it, and the box of extra slides they listed, and I see us having hours of educational fun. If you don't get a book of experiments and activities, you might run out of ideas quicker. With the great bargain you're getting on the scope, another $10 on a book isn't a huge deal. We haven't used any of the slide-making tools that came with it, but there's a nice bag of goodies. This is a great product that will allow the family to enjoy together and learn in the process. I seriously see this as something we'll use through high school, and will help immensly when the dreaded science projects start being assigned! Don't spend any more money than this. It's just not necessary! From personal experience, research before buying anything cheaper. You'll be compromising on quality and possibly trying to explain to your child why his Christmas present needs to go in the trash.

If your choice is between this and plastic toy microscopes, this is definitely the way to go. The optics are pretty good and the idea of having the light at the top to use it as a dissecting scope is good in principle. It is well built, and would probably last a long time. The LED light is powered by batteries, which makes it easy to carry it around. You have the option of switching an eyepiece for one that can be connected to a computer, so you could actually "project" the specimen to your computer (NOTE: the digital eyepiece is NOT included, but it has a standard size, removable eyepiece, so you have the option using a digital one).

However, it has some considerable flaws. You can't really regulate the intensity of the light (changing the diaphragm setting has very little effect). The light is too bright. Unless your slide is very dense, it feels like someone is shining a flashlight directly into your eyes.

It would be nice to have a choice between mirror and light, so you are not always dependent on batteries, and you have at least one option to regulate the light going through.

The stage can be moved up beyond the point where it touches the objectives, which can break the slide and eventually damage the lenses.

The stage can't be moved sideways, so it is hard to explore different parts of the slide. But this is something that is typical of budget microscopes.

When you set it to use the top light to use it as a dissecting scope, you have very little depth of field. This is not surprising, as this is really an optical microscope. It works OK if you use it to examine pretty flat objects, like coins, but not that well if you try to see objects with more curvature like, for example, sea shells.
