Condensers

Condensers are glass tubes or coils used to cool and condense vapors or gases. They are often used in distillation processes to convert vapors into liquid form. The condenser is connected to the apparatus, allowing the vapor to pass through and be cooled, resulting in the condensation and collection of the desired liquid.

Separatory Funnels

Separatory funnels, also known as separating funnels, are conical-shaped glassware with a stopcock at the bottom. They are used for liquid-liquid extractions or phase separations. By allowing immiscible liquids of different densities to separate into distinct layers, separating funnels facilitate the separation and collection of desired compounds.

Drying Tubes

Drying tubes are glass tubes filled with a desiccant, typically calcium chloride or silica gel. They are used to remove moisture or impurities from gases passing through them. Drying tubes are commonly employed in setups where dry and clean gases are required, such as in chemical reactions or analytical procedures.

Evaporating Dishes

Evaporating dishes are shallow, flat-bottomed glass or porcelain containers used for evaporating liquids to obtain solid residues. They have a larger surface area that facilitates faster evaporation. Evaporating dishes are commonly used in analytical chemistry and research laboratories for concentrating or isolating substances.

Chromatography Columns

Chromatography columns are glass tubes or columns used in chromatographic techniques, such as gas chromatography or liquid chromatography. These columns allow for the separation and analysis of complex mixtures by utilizing the differential affinity of the components for the stationary phase. They are available in various sizes and designs to accommodate different sample volumes and separation requirements.
