2. Condenser (laboratory) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(laboratory)

   Condensers with forced-circulation cooling usually employ water as the cooling fluid. The flow may be open, from a tap to a sink, and driven only by the water pressure in the tap. Alternatively, a closed system may be used, in which the water is drawn by a pump from a tank, possibly refrigerated, and returned to it. Water-cooled condensers are ...

3. Liebig condenser - Wikipedia

   en.wikipedia.org/wiki/Liebig_condenser

   Liebig condenser. The Liebig condenser (/ ˈ l iː b ɪ ɡ /, LEE-big) [1] or straight condenser is a piece of laboratory equipment, specifically a condenser consisting of a straight glass tube surrounded by a water jacket. In typical laboratory operation, such as distillation, the condenser is clamped to a retort stand in vertical

4. Condenser (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Condenser_(heat_transfer)

   The Liebig condenser is simply a straight tube within a cooling water jacket and is the simplest (and relatively least expensive) form of condenser. The Graham condenser is a spiral tube within a water jacket, and the Allihn condenser has a series of large and small constrictions on the inside tube, each increasing the surface area upon which ...

6. List of vacuum tubes - Wikipedia

   en.wikipedia.org/wiki/List_of_vacuum_tubes

   This is a list of vacuum tubes or thermionic valves, and low-pressure gas-filled tubes, or discharge tubes. Before the advent of semiconductor devices, thousands of tube types were used in consumer electronics. Many industrial, military or otherwise professional tubes were also produced.

7. Vacuum ejector - Wikipedia

   en.wikipedia.org/wiki/Vacuum_Ejector

   The strength of the vacuum produced depends on the velocity and shape of the fluid jet and the shape of the constriction and mixing sections, but if a liquid is used as the working fluid, the strength of the vacuum produced is limited by the vapor pressure of the liquid (for water, 3.2 kPa or 0.46 psi or 32 mbar at 25 °C or 77 °F). If a gas ...

9. Ground glass joint - Wikipedia

   en.wikipedia.org/wiki/Ground_glass_joint

   Crude versions of conically tapered ground glass joints have been made for quite a while, [1] particularly for stoppers for glass bottles and retorts. [2] Crude glass joints could still be made to seal well by grinding the two parts of a joint against each other using an abrasive grit, but this led to variations between joints and they would not seal well if mated to a different joint.
