New Labware

It not the most exciting of topics but to some folks it can be very important. Spectrum has added several new pieces of labware to our product line.

First new item are small Weighing Bottles available in both 10ml and 20 ml.

Weighing Bottles

Weighing bottles are thin borosilicate glass bottles that are used to help weight solids on electronic balances. Their light weight minimizes any issues when taring out such a balance. Like any other piece of labware, hundreds of other uses can be found for it. Especially attractive is the ground-glass lid!

Next up is a 250ml Separatory Funnel. These are used to distinguish between the densities of two different liquids.  But they often get used as dispensers. We’ve even seen them on cooking shows! They are made of borosilicate glass and have a ground glass stopper and stopcock. We’ve carried versions of these in the past (and still do) but at just $26.95 this is a real bargain.

Finally we have a new selection of Dropping Bottles. Now we’ve carried dropper bottles for some time but this new model has a glass stopper system that many folks like to have:

We hope to have great success with these new items! Many folks have asked for labware like this so be sure to get some today!

New ‘Information Intensive’ Posters!

We’ve added three new “information intensive” posters from Feennix.  These popular posters are laminated for durability, and contain large amounts of excellent pictures, insets, and most of all INFORMATION. We’ve had great success with this line and so we decided it was time to expand it!

First new poster is the Human Evolution poster.

Much like the popular Eras of Life poster  this poster covers several eras and species that make up our ancestors. The chart starts with Australopithecus africanus and works its way up to Homo sapiens of 30,000 years ago.  Insets cover migration, society, relationships, and much more! This poster is a must for anyone studying human evolution.

Next up is a popular subject, even among dinosaurs, the Tyrannosaurus poster.

In this poster the center portion shows all nine members of the Tyrannosaur family, with T.Rex taking center stage.  Insets cover recent discoveries, behavior, ancestors, and anatomy! This poster is a must for any dinosaur fan!

Finally, the insect world gets a voice with Insect Identification

This chart is full of information that will help the reader identify insects by their physical characteristics. The chart is detailed enough to identify the order from which any insect comes! This poster is popular with students, collectors, and schools. Recent streamlining of the design has made it even easier to use.

These posters are great new additions to our product line. If you’ve ever enjoyed any of the “information intensive” posters we carry these will be great additions!

Zube Tubes!

Zube Tubes are a sound-making toy that has been around for a couple of decades! Or rather they would have been except that…they went away.  Its not certain what happened to make the Zube Tube go away – they were certainly popular enough and available in lots of places, but they did. So for a few years kids and adults could not get a nifty new Zube Tube.

But now they are back!

Zube Tube

Zube Tube

The design of the Zube Tube is simple: A spring is stretched inside a tube with plastic caps at the ends that help the noise. When you shake the Zube Tube, strum the spring, or speak into it the spring makes a bizarre space-wars sound that most folks should recognize from the movies. Shaking it in different ways, speaking in different tones, and strumming the spring in different ways changes the sound in small ways so almost always get a different sound!

You can’t really describe sound by typing, so we made a video of the Zube Tube in action!

The Zube Tube – if nothing else it will confuse the Postman or UPS guy when one is delivered to your house!

Comparison Microscopes

Often mentioned on forensic-based TV cop-shows, but rarely actually shown , Comparison Microscopes are excellent tools not just for forensic work, but also for comparing different tissue types, teaching, and for checking diseased vs. healthy tissues. They are used to compare the samples on two slides side-by-side.


They look clunky, because they essentially are just two microscope bodies attached a the top by an optical bridge. The mechanics are 2 high quality binocular microscopes which combine 4 DIN objectives (or 5 in the advanced model), a large stage, a mechanical stage, coarse & fine focus,  and N.A. 1.25 Abbe Condensers among many other features.

To do a comparison of slides, you place 1 slide on each stage, bring them to focus, and make adjustments on the optical bridge.

The resulting image shows the samples side-by-side. Here is one example of a human stomach cell side-by-side with a human kidney cell:

Comparisons can be made with almost anything that can be put on a slide. Comparison Microscopes are invaluable in teaching students to see diseased tissues vs. healthy, forensic work, and a host of other fields.

50th Anniversary of Man In Space

50 years ago today Yuri Gagarin became the first man in space. Until that time, only unmanned satellites and experimental animals had been sent up into space. It was a major coup in the Space Race for the USSR. Less than 1 month later, the USA sent up Alan Shepard , although his flight was suborbital.

There were other differences in the two flights as well: Shepard had some control over his flight, wheras Gagarin’s was completely automated. Shepard also splashed down in the Ocean wheras Gagarin bailed out of his Vostok 1. This detail was kept quiet by the USSR since the required standard for a successful spaceflight was that the craft would land on its own. Although this was a ‘violation’ of the Spaceflight standards of the time,  only a few people have since made much of an issue of it and Yuri is generally considered the first man in a successful spaceflight.

Unlike Shepard, Gagarin also never returned to space, and he died in a plane accident in 1968. In the years since the Soviet Union collapsed, rumors have surfaced that other Cosmonauts were sent into space before Gagarin but did not survive – their failure being hushed up by the tight-lipped Soviet Union. The facts are that such dead cosmonauts were either fictional, died on Earth, or were dismissed for misbehavior.

So here’s to 50th years of Manned (if automated) Spaceflight!

Frogs are back!

We carried them last year for Spring and Summer so we brought them back for this year’s warm season. Its the EcoAquarium frogs!

EcoAquarium Frogs!

Sadly, these are sold in-store only. Shipping them is too much trouble. But for those of you local to the store you can come in and get your own little aquarium with frogs!

These are very low maintenance pets.  In fact we think the only pet that requires less maintenance are the Ecospheres. The frogs need feeding only twice a week, and their tanks only need to be cleaned twice a year! You can’t beat that!

The frogs are African Aquatic Dwarf Frogs, a species that prefers to remain underwater inhabiting a very small area. As a result the frogs are very comfortable in the small EcoAquariums. They live 2-3 years if cared for, and care is very easy.

You can’t take the frogs out to play with them – they are too fragile. But while they might lounge around a lot they do cavort and swim around.

The trick to the EcoAquarium is the living gravel that comes on the bottom. If helps to ‘scrub’ the tank of waste products. The colorful gravel on top gives it a nice look and the high-protein/low waste food you feed them helps keep the tank clean. The EcoAquarium should be kept in indirect light – direct sunlight should be avoided as it encourages algae growth.

Frogs are in stock in the store. You can also pick up a food pack (1 years supply),  a total care pack (includes food and gear for making water changes) as well as a decorative base. Come on down and get some frogs if you can!

3D Lenticular Motion Bookmarks!

This is a product that we admit there were some doubts about, but it has actually shown itself to be a very popular item: A series of rulers and bookmarks that have high-quality 3D lenticular images that appear to move!

3D Lenticular Bookmark!

Sadly, these pictures cannot really do these things justice. So for that we have a video of our display unit:

As you can see from the video, these are not the lenticulars of yesteryear where you would have only two or three ‘scenes’. In this case there are enough images to make it seem like the animals are really walking (or climbing).

You can also  see from the video there are more than just penguins. Another popular model is the Gears & Robots

The Triceratops is also popular:

We also have them in larger sizes: The 12″ rulers (the above are 6″ Rulers/Bookmarks) are quite popular, such as the Walking T-Rex 12″ Ruler

These lenticular 3D Rulers/Bookmarks make great gifts and add a little fun to the ordinary bookmark!
