These Borosilicate Glass Liebig Condensers find wide usage in the laboratory such as distillation, reflux operations, extraction etc. Sealed inner tube, large capacity of water jacket gives efficient cooling. Sized by effective length. 22 mm diameter.
Graduated Interval: 0.10ml Borosilicate glass burettes offer accuracy, reliability and durability even after repeated usage. Each burette is individually calibrated for precision and high accuracy. All graduations are durable in white enamel. The burette stopcocks are specially ground so they provide leak resistant operation. Burettes with general purpose (gp) screwthread stopcocks with PTFE keys offer excellent flow control. Also, burettes with these gp stopcocks have unique Fluon/glass seals that prevent leakage.

Graduated Interval: 25ml These bottles are made of translucent and unbreakable low density polyethylene. The distinguishing feature that these bottles contain is the built-in delivery tube making it a one-piece wash bottle. These bottles are graduated on the outer surface to reflect an approximate volume of solution filled or dispensed.
Versatile, polypropylene containers are graduated in ounces and milliliters. Graduated to 2 ounces.
These polypropylene bottles are rigid, translucent and have excellent contact clarity. These bottles can be autoclaved filled as well as empty. The polypropylene cap has a built-in seal ring to make these bottles leak proof.

This poster begins by defining a mineral. It then expands on that by exploring atoms, molecules, and crystal structure. The various crystal structures are explained. This is followed by an excellent summary of the mineral classes.
Mineral collectors and students want to identify their specimens. However, specimens of the same mineral can vary greatly in appearance, which can make that a daunting task. Identification is based on a number of properties.
This poster provides an outstanding introduction to those properties: hardness, habit, luster, cleavage, specific gravity, color, streak, and fluorescence. Illustrations are used to explain principles. Photographs of truly outstanding specimens are used as examples.

Fossils were a mystery for thousands of years; then a few pioneering scientists realized that they were the remains or traces of once-living organisms.
Well-known bone-type fossils are actually rocks, the result of a process called mineralization in which minerals replace decaying tissue. This process is shown and explained. All of the other fossil types are also explored.
The rarity of fossils is dramatically presented, and strange things sometimes mistaken for fossils are identified. There’s an introduction to fossil expeditions and a summary of how fossils contribute to our understanding of the earth and life on it.
There is an especially helpful section on the relationships between fossils and geology. It covers the principle of original horizontality, the law of superimposition, the principle of faunal succession, the geological time scale, index fossils, relative dating, and absolute dating.
All of this is conveyed through detailed illustrations showing the processes, excellent photographs of representative specimens, and interesting and informative captions. This poster is a great aid to museum interpretive programs and is extremely beneficial in the study of both life and earth sciences.
