A water still produces distilled water, used for applications needing high purity: medical sterilization, labs, CPAP machines, car batteries/coolants, steam irons, humidifiers, aquariums, and spotting-free car washing, as it lacks minerals that cause scale, corrosion, or interfere with tests, though less ideal for drinking due to flat taste. 

Borosilicate glass beakers are used in laboratories because they offer excellent resistance to thermal shock and chemical corrosion, making them highly durable for a range of applications, including heating liquids and handling aggressive chemicals. 

A borosilicate glass still head is crucial for lab solvent purification due to its excellent thermal shock resistance, chemical inertness, and smooth surfaces, allowing for safe, accurate distillation of solvents for drying or deoxygenation using PTFE stopcocks and standard taper joints for leak-free connections, perfect for routine lab needs. These heads, often from brands like Pyrex or Duran, connect flasks, condensers, and thermometers, providing clean vapour flow for high-purity results. 

Borosilicate glass funnels are versatile lab tools used for precise liquid/powder transfer, filtration (with filter paper), separating liquids (like in separatory funnels), sample prep, and handling hot/corrosive substances due to their thermal shock resistance and chemical inertness, making them ideal for chemistry, cooking, and industrial tasks. 

A laboratory glassware set provides essential tools (beakers, flasks, cylinders, etc.) for mixing, heating, measuring, and storing liquids/solids in science labs, crucial for everything from basic experiments to precise titrations, distillations, and cell culture, using borosilicate glass for thermal/chemical resistance and transparency. Each piece, like burettes for dispensing or Petri dishes for culturing, serves a specific function for accurate and reliable results. Common Glassware & Uses:

• Beakers: General containers for holding, mixing, heating, & decanting liquids.
• Erlenmeyer Flasks (Conical): Mixing/swirling without spilling, heating, storing; flat bottom for direct heating.
• Volumetric Flasks: Preparing solutions with very precise concentrations.
• Test Tubes: Small-scale reactions, sample testing, observation.
• Graduated Cylinders: Measuring liquid volumes accurately (less precise than volumetric, more than beakers).
• Burettes: Dispensing variable, precise volumes of liquid (e.g., titrations).
• Pipettes (Graduated/Volumetric): Transferring small, exact liquid amounts.
• Funnels: Channeling liquids/powders into narrow openings, filtration (Buchner).
• Condensers: Cooling hot vapors back into liquids (distillation, reflux).
• Petri Dishes: Shallow dishes for culturing cells/microbes, evaporation.
• Watch Glasses: Covering beakers, small-scale crystallization/evaporation.
• Desiccators: Removing/absorbing moisture from samples. 

Why Glassware is Used:

• Chemical Inertness: Doesn't react with most chemicals.
• Thermal Stability: Borosilicate glass withstands high heat & rapid temperature changes.
• Transparency: Allows visual monitoring of reactions.
• Precision: Calibrated markings ensure accurate measurements for reliable results. 

Borosilicate glass volumetric flasks are crucial lab tools for preparing solutions of exact, known concentrations, used in titrations, dilutions, and creating standards for research, pharma, and industry, benefiting from borosilicate's chemical/thermal resistance for accuracy, durability, and safe handling with hot/corrosive liquids, unlike regular glass. Their narrow neck and single calibration mark ensure high-precision volume measurement, preventing evaporation and contamination, and are often Class A (high accuracy) or Class B (general use). 

A soda glass desiccator with a cover is an airtight lab container using a desiccant (like silica gel) to create a dry environment, primarily for storing moisture-sensitive chemicals (hygroscopic salts, powders) and for cooling oven-dried samples (weighing bottles, crucibles) without them reabsorbing water, ensuring accurate mass measurements in chemistry, biology, and pharma. Made of thick glass, it maintains low humidity for preserving dry items or accelerating their drying process, often with vacuum capability for faster results. 

Glass filter assemblies are crucial lab tools for vacuum filtration, primarily used for purifying solvents (HPLC), removing particles from liquids (particulate analysis), and sterile filtration of media/buffers in microbiology, offering chemical resistance with borosilicate glass for analysis, media prep, and sample cleaning. They work by using vacuum to pull liquids through a membrane filter held by a glass funnel and support base, collecting pure filtrate in a flask. 

Conical flasks (or Erlenmeyer flasks) are versatile lab tools for mixing, heating, storing, and swirling liquids without spilling, thanks to their flat base and tapered body, ideal for titrations (holding analyte), microbial culturing (allowing gas exchange), sample prep, and reactions needing agitation, with graduations for approximate volume checks.  

Glass BOD (Biochemical Oxygen Demand) bottles are specialized lab containers used for environmental monitoring, primarily to measure the oxygen used by microbes breaking down organic matter in water samples (sewage, wastewater, rivers) over 5 days, indicating pollution levels, featuring airtight stoppers and unique shapes to prevent air leaks during incubation. They're vital for assessing water quality, wastewater treatment effectiveness, and ecosystem health, made from durable borosilicate glass to resist thermal shock. 

A separating funnel with a glass stopcock is a key lab tool for liquid-liquid extraction, separating mixtures of immiscible liquids (like oil & water) by density, purifying compounds (APIs, natural products), and removing impurities in organic/analytical chemistry, relying on its pear shape for settling and stopcock for precise layer draining. The glass stopcock offers controlled flow, essential for separating layers after shaking and venting pressure, making it vital in pharma, environmental, and biotech labs. 

Specimen Gas Jars are versatile lab containers, primarily used for storing, transporting, and observing biological/chemical samples like preserved organisms (in alcohol/formalin), live insects, or even gases, thanks to their clear, durable plastic (Polypropylene/PS) and tight-fitting caps that protect contents, prevent leaks, and allow easy viewing for experiments or educational purposes in schools, colleges, and research labs. 

Rectangular specimen jars are versatile containers used in labs, museums, and forensics for storing and displaying biological/chemical samples like organ slices, small animals, or tissue in preservative fluids (formalin/alcohol). Their shape is ideal for larger, flatter specimens, offering protection, visibility, airtight sealing, and easy transport, crucial for accurate analysis, education, and historical preservation across fields from medicine to environmental science. 

Fractional columns in labs separate liquid mixtures with close boiling points through repeated vaporization and condensation, essential for purifying chemicals, recovering solvents, and creating pure components for pharmaceuticals, flavors, and petrochemicals, acting as a crucial tool in chemical analysis and research by providing highly pure fractions based on volatility. They work by providing a large surface area (packing/trays) for vapor-liquid contact, creating a temperature gradient where lighter components rise and heavier ones condense, effectively allowing for multiple "simple distillations" in one apparatus. 

A glass Liebig condenser cools hot vapors back into liquids, primarily used in distillation to separate substances, and also for reflux to keep solvents from escaping during prolonged heating, featuring a straight inner tube for vapor and an outer water jacket for cooling. Its simple design, often with ground glass joints, makes it essential for basic chemistry labs to prevent volatile loss, improve yields, and ensure safer experiments. 

Amber bottles, conversely, are designed to protect light-sensitive reagents from damaging UV rays. Their darkened colour filters out harmful light, thus prolonging the life of photosensitive substances.

Borosilicate glass BOD (Biochemical Oxygen Demand) bottles are specialized lab containers used for water quality testing, measuring oxygen consumed by microbes decomposing organic matter in water samples (like sewage, effluents) over 5 days, assessing pollution levels, and checking wastewater treatment efficiency, thanks to their airtight design and resistance to heat/chemicals, ensuring accurate anaerobic incubation. 

Borosilicate glass conical flasks are excellent vessels for growing microbial cultures (bacteria, fungi, yeast) due to their heat and chemical resistance, which facilitates sterilization and incubation. The conical shape and narrow neck are ideal for swirling and aeration while minimizing the risk of contamination and spills. 

Soda glass mortars and pestles are versatile tools for crushing, grinding, mixing, and emulsifying substances in labs, pharmacies, kitchens, and schools, offering transparency for sample observation and good chemical resistance, ideal for making powders, pastes, and fresh spices, though they require careful use to avoid breakage compared to harder materials like ceramic. 

Borosilicate glass flat-bottom flasks are versatile lab tools used for stable heating, mixing, storing, and performing chemical reactions like distillation and synthesis, thanks to their thermal shock resistance, chemical inertness, and flat base that sits securely on hot plates or surfaces without a stand, making them perfect for boiling liquids and precise experimental setups. They're also used in culinary applications, homebrewing, and microbiology for controlled heating and mixing of ingredients or cultures.

It was Sir Isaac Newton who about 300 years ago proved that white light such as sunlight is a mixture of several coloured lights that we perceive as white. Here we simplify the problem by saying lets pick three coloured lights and see whether we can produce white light by adding them together. The m of this experiment is to prove whether Red+Green+Blue = White.
