Selecting a cuvette is a five-decision process: (1) material — quartz, glass, or plastic by wavelength range; (2) path length — 0.1 to 200 mm by analyte concentration via Beer-Lambert; (3) form factor — standard, micro, sub-micro, large-window, flow cell, or screw-top by sample volume and application; (4) fabrication grade — Standard 80, Sintered 80/83,
Fused silica vs natural quartz vs borosilicate capillary tubes is a material-grade decision driven by purity, UV transmission, and chemical resistance requirements. Fused silica (synthetic quartz, JGS1/JGS2/JGS3) has < 1 ppm metal impurities and full UV transparency to 185 nm; natural quartz crystal has 50–500 ppm impurities and is mainly used for piezo applications; borosilicate
Quartz is one of the most common minerals in the Earth’s crust. As a mineral name, quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found in all forms of rock: igneous, metamorphic and sedimentary. Quartz is physically and chemically resistant to weathering. When
From heat resistant Pyrex to PVB laminated safety windshields, glass is available in many forms. Some of the materials commonly referred to as glasses are actually plastic or plastic-glass mixes, although the term glass does not explicitly indicate a particular chemical composition. The term can describe any number of hard, amorphous, inorganic, and uniform solids
Curious about the different types of tubes that are used in science labs? Consider this. According to Science Times: “A tube is one of the most common laboratory equipment. Lab tubes are normally found in science labs in their special-purpose racks. Labs use them to store conduct and materials to be used for experiment and
Lab equipment used for liquids includes 15 essential vessels grouped by function: containers (beakers, bottles, flasks), measuring vessels (graduated cylinders, burets, volumetric flasks, pipets, micropipets), heating & reaction vessels (round-bottom flasks, retorts, condensers, distillation flasks), and specialty handling (separatory funnels, filter funnels, watch glasses, dropping bottles). Each category has a distinct precision class — graduated
Quartz and calcite are common minerals in the rocks around the world. Both minerals form in a variety of colors, such as purple, white, brown, gray and colorless, which at times makes them appear similar. However, these two minerals have many distinctively different physical and chemical properties that differentiate them. Hardness Mineral hardness is a
Laboratory flasks are specialized glass vessels with narrow necks and wider bases, used for mixing, heating, distilling, titrating, and storing liquids in chemistry, biology, and analytical labs. The 14 most common types include the Erlenmeyer flask (mixing without splashing), Florence flask (even heating), round-bottom flask (distillation and reflux), volumetric flask (precise dilution to ±0.05%), Büchner
Fused silica and fused quartz are both non-crystalline forms of silicon dioxide (SiO₂) — chemically identical but distinguished by purity, manufacturing route, and OH content. Fused quartz is made by melting naturally occurring crystalline quartz at 2,000+ °C; fused silica is synthesized from gaseous SiCl₄ via flame hydrolysis or plasma deposition, producing higher purity (≥
Quartz is a crystalline form of silicon dioxide (SiO₂) — the second most abundant mineral in the Earth’s crust and one of the most useful natural materials in science. Pure quartz is colorless, transparent, has a hardness of 7 on the Mohs scale, and exhibits piezoelectric properties. In optics and spectroscopy, the term “quartz” most
