A stereo microscope consists of the ocular lens (the eyepiece that you look through) and the objective lens (the main optical lens that’s closest to the sample). Our stereo microscopes give users a three-dimensional view with lenses that have two optical eye paths.

Our stereo microscopes are used for examining larger specimens in 3D that are unable to fit on a slide. The specimens are usually opaque meaning light cannot pass through them. They can be used to view insects, crystals, plant life, circuit boards, and other samples. This is compared to a compound microscope, which is designed when specimens can fit on a slide.

In water, aluminum’s durability is vulnerable in the presence of chlorides and heavy metals. Pitting is common even in natural fresh and drinking water, but a harmful attack increases where water is stagnant and prolonged wetness, and with exposure to sea water, to which some Al alloys show more resistance than others.

A basic stereo microscope costs anywhere from $79. The stereo microscope price range changes if you add features, and at the high-end price, a stereo fluorescence microscope can cost upwards of $18,000.

The Meiji EM-60 Binocular Stereo Zoom Microscope consists of a 10" pole stand, 360° rotatable head, and 16" dual-arm LED illumination.

A stereo microscope is a type of optical microscope that's designed for examining 3D objects at much lower magnification. They use light reflected from the surface of an object rather than light shining through it (like a compound microscope does). It's often called a stereoscopic or dissecting microscope.

The main limitation of a stereo microscope is the low level of magnification when compared to a compound microscope. Our compound microscopes for sale can achieve higher levels of magnification than our stereo microscopes.

The ACCU-SCOPE EXS-210 Stereo Microscope represents excellent value and ease of use. It offers sharp images, rechargeable LED illumination, and effortless focusing. The stand is sturdy and has a built-in handle for easy portability. This is a great choice for students of all levels and light industrial inspections.

Another example of aluminum degradation is due to erosion-corrosion caused by high velocity, turbulent water. This type of aluminum corrosion progresses slowly in plain water, but accelerates significantly at pH levels above 8, especially if the water streams contain carbonate and silica.

For live video and image capture, the Scienscope SSZ-II Stereo Zoom Microscope is a cost-effective solution. The microscope features a dual-arm boom stand, 1080p HDMI/USB camera, high-intensity LED ring light, and a 23" HD monitor. Every component is designed for high performance and durability.

Untreated aluminum (Al)boasts a fairly high corrosion resistance in most normal environments. Even so, aluminum surfaces suffer from various types of corrosion in many urban, rural and industrial situations. If your aluminum surfaces, parts, structures, or machinery require corrosion protection, simply use the contact form on the right to let us know your tasks, so we may help you select the best product for your needs (or direct you elsewhere when a STEEL-IT® coating is not the advised solution).

Aluminum is the cheaper, lighter, softer metal with a much higher electrical conductivity. Although aluminum itself is widely used for its toughness against corrosion, stainless steel has a somewhat different set of properties and hence advantages. For example, stainless steel is the much harder metal, less chemically reactive, with much lower electrical conductivity and much higher heat resistance. Importantly, aluminum is much more prone to chemical interaction with food and is consequently considered less food safe than stainless steel. (STEEL-IT® coatings are officially USDA-approved for incidental contact with food.)

The difference between a compound and a stereo microscope comes down to magnification level and sample type. A compound microscope is usually used for samples that you can’t see with the naked eye, displayed on a slide. Whereas a stereo microscope tends to use a large sample that’s often opaque and is used to see 3D objects in more detail.

Another environment that canrender aluminum’s strength more vulnerable is soil. Present-day knowledge of specifics of soil-induced aluminum corrosion is far from complete and needs a great deal more research. Soil varies a great deal in chemical composition and moisture levels, making it hard to predict how an embedded aluminum structure will react to the combination of minerals, organic matter, pH, and so on. that it comes into prolonged contact with, along with the soil’s electrical conductivity. For that reason, reinforcing aluminum structures that are to be interred in soil with a protective coating is often a requirement, and Steel-It® offers an excellent, economically competitive choice.

Crevice corrosion takes place in narrow crevices with accumulated moisture, most typically in marine atmospheres or on the exteriors of vehicles, resulting in “water staining”. Rainwater or condensation penetrates between metal surfaces through capillary action. (A typical cause of condensation is the difference between night and day temperatures in indoor facilities or under tarpaulin.)Furthermore, open air or atmospheric corrosion of aluminum can happen during prolonged exposure to condensation wetness(over 80% humidity at condensation temperatures, just above 0°C).A sulfurous atmosphere may be the cause of some pitting, but a high concentration of chlorides and other salts in the atmosphere can undermine aluminum’s durability, as can dirt corrosion (caused by dirt or mud buildup on an aluminum structure) can likewise reduce aluminum’s strength. Here too, STEEL-IT coatings for aluminum come to the rescue.

Stainless steel displays much higher corrosion resistance than aluminum under a high pH. Aluminum starts to corrode rapidly at approximately pH 10 and dissolves in a solution with a pH of 12. For that reason, an aluminum surface can be damaged by a high-pH oven cleaner aerosol, while stainless steel is immune to it. Many though not aerosols such as hair sprays, air fresheners and insecticides are more prone to react with aluminum than with steel, depending on their respective formulas. Organic halogens (e.g. carbon tetrachloride, widely used by the cleaning industry and in fire extinguishers) can violently corrode aluminum.

There are two types of magnification systems in a stereo microscope, Fixed and Zoom. Fixed magnification is achieved using a paired set of objective lenses with a set degree of magnification. Zoom magnification is capable of a continuously variable degree of magnification across the set range of the stereo microscope. You can also adjust magnification by changing the microscope eyepiece.

Pitting, the most common type of aluminum (aluminum) corrosion, occurs in the presence of salts (chlorides) dissolved in water or moisture, causing an aesthetic ugliness and in some cases undermining aluminum’s strength. Trying to remove pitting with alkaline detergents can prove too harsh for aluminum and destructive in its own ways. STEEL-IT works well for the prevention of corrosive pitting. As a bonus, although a common recommendation on the design of aluminum surfaces is to adhere to profiles that avoid angles and pockets where water or moisture can gather, STEEL-IT coatings may help overcome this limitation and support greater design flexibility.

In spite of aluminum’s decent resistance to a wide range of chemical agents, it is vulnerable to corrosion attack in low and high pH environments (pH below 4 or above 7) due to the destruction of the passivation layer. For this reason, inorganic acids and heavy-duty alkaline solutions – except for nitric acid and ammonia – can be extremely corrosive to aluminum structures. The effect of the presence of heavy metals (notably, copper, lead, mercury, nickel, and tin) in aluminum alloys is a major issue in acidic environments. Even moderately alkaline water solutions will likewise cause corrosion unless preventive measures are taken. Alkaline environments strip off aluminum’s naturally forming oxide layer. On building sites, aluminum is easily and permanently stained when it comes into contact with mortar, concrete and other damp alkaline construction materials. Worse, aluminum cast into concrete may corrode when the concrete fails to dry in a timely fashion. Aluminum corrosion within concrete is highly undesirable as its volume may produce cracks in the concrete. STEEL-IT chemical corrosion resistant coatings protect aluminum, blocking corrosion and eliminating or significantly reducing most of these risks.

These are stereo microscopes combined with a digital microscope camera to be used for inspection and quality control, offering a live video and/or computer screen that’s fully equipped with comprehensive software.

STEEL-IT® coatings provide an excellent extension of aluminum’s natural anticorrosive properties, prolonging its life in challenging environments. Please use the quick contact form to address the specifics of your project.

Aluminum’s natural resistance to corrosion is due to the spontaneous formation of an adherent, impermeable layer of aluminum oxide (Al2O3) – the so-called passivation layer – which tends to self-repair immediately even when breached due to aluminum’s high occidation rate. The common AlMgSi alloys have an even higher resistance to corrosion. Often, however, this is not enough. Apart from the passivation layer, aluminum itself is chemically a highly reactive metal. In challenging environments, aluminum is subject to pitting, crevice corrosion, chemical, and less commonly other types of corrosion. The presence of copper or of certain other metals in aluminum alloys makes them especially vulnerable to a corrosion attack.
