This kit brings together frequently used adapters, condensers, flasks, funnels, stoppers, joint clips, clamps, and support accessories in one coordinated 24/40 glassware set. It is suitable for scientific laboratories, research laboratories, university laboratories, and routine chemistry workflows where users need to assemble multiple compatible apparatus configurations. Most glass components use 24/40 standard taper joints. A 24/40 joint can fit compatible 24 mm standard taper joints in other joint-length systems, such as 24/29, although the insertion depth will differ. Glass components are made from borosilicate glass 3.3, a standard laboratory glass material known for low thermal expansion and good resistance to many common laboratory chemicals. Use proper laboratory heating equipment, clamps, stands, joint clips, and safe handling practices when assembling, heating, cooling, or applying vacuum to glassware. US Standard Size Joint Will Fit into European Standard Size Joint: Standard Taper Ground Glass Joints are interchangable.For either frosted, presicon-ground standard taper joints (same size),the inner ground surfaces (male joint) make a good seal with the outer(female joint)). The joint size is described by the form A/B. The first number A represents the outer diameter (OD) in millimeters (mm) at the widest point of the inner (male) joint and the second number B represents the length of the joint. For example, a 14/20 joint is 14 mm wide at the top (the widest part) and is 20 mm in longth. The joint has a standard taper 1:10, any two joints (male and female) with the same outside diameter (A)can fit into each other ,no matther how lenght the joints are. For example, a 24/40 (US standard size) joint on a condenser will fit into a 24/29 (European standard size)flask but the ground glass joint will protrude (40 - 29) 11mm into the flask. A 3 way distilling adapter ,also called 3 way connecting adapter,distilling head,is designed with three joints: one female joint at top which is designed to hold a thermometer adapter accommodating thermometer to monitor the vapor temperature during the distillation,and two male joints,one at the side arm to connect a liebig condenser or coiled condenser and one at the bottom to connect a distillation flask(round bottom flask) or a distillation column(vigreux column or hemple column). This three way connecting adapter is commonly used in the distillation apparatus for distillation,vacuum distillation,fractional distillation,it is quite similar to three thermometer adapter HMA016103,but the top outer joint is replaced by a thermometer inlet cap. This distillation adapter is with 24/40 standard female taper joint at top,and one 24/40 male joint at side arm and one 24/40 male joint at bottom. The Claisen adapter can be placed on top of a round bottom flask to convert one opening into two, For example, attach one upper joint of the Claisen adapter to a condenser and one to an additional funnel or accept a thermometer adapter for temperature measurements in a distillation apparatus; This Claisen adapter has two upper outer joint to attach any lab glasswarer with inner joints, and a lower inner joint to entry into a boiling flask with outer joint. The sizes of the three joints are the same 24/40. The laboy glass thermometer adapters have a standard taper ground male joint at one end while the other end is an open top compression cap ideal for fitting a plain stemmed thermometer into jointed glassware assemblies in organic chemistry. A vacuum-tight seal is created with the open top compression cap and o-ring to allow adjustable immersion of thermometers or bleeding tubes;Cap is suitable for use to 150 °C.The ground glass joints allow the laboratory glassware to be assembled, leak-free, without stoppers. During the organic chemistry glassware for performing fundamental organic laboratory activities ,the glass adapter with thermometer opening is used frequently, especially in distillation or fractionation process. Glass Vacuum take-off adapter,105 degree bent,short stem design,with 24/40 standard outer joint at top to add a vacuum line to a setup,the 24/40 lower inner joint is used to facilitate a more vertical relationship with the receiving glassware. With serrated hose connection. The glass hose connector has an O.D.of 10mm at the largest serration ideal for vent or introducing glass or vacuum during a vacuum distillation,fractionation etc in organic chemistry,accepts 3/8” ID flexible rubber or PTFE tubing. With sealed-in drip tip ,used to connect a glass condenser to a receiving flask for vacuum distillation. The 3 way distilling thermometer adapter has a compression cap to form a vacuum tight seal of plain thermometer on Top. With 24/40 two inner joints at bottom and side,and the two joints are at a angle of 75 Degree .The bottom joint is usually connected to a distilling column for fractionation distillation or a distilling flask for the steam or vacuum distillation.The side joint may connect to a liebig or west condenser for water in and out when the temperature below 150 degree C,connect a air condenser if temperature above 150 degree C. The compression cap and o-ring fitting the thread opening at the top of the adapter, accommodating a thermometer or bleeding tube. A fractionating column or fractional column ,is a glass tube designed with many deep pointed intendations in its sidewall and two taper joints at both ends, used in laboratory fractional distillation in organic chemistry.This distillation column with vigreux belongs to air-cooled type condenser.Used in chemistry experiments involving fractional distillations or for separating two parts of a mixture based on their boiling points. With 24/40 top outer and bottom inner joints.The lower joint usually fits a distillation flask with standard female joint,the upper joint connects a three way distillation adapter. The indentation length is 300mm. The “graham-style”condenser having the configuration that the jacket tube contains coolant,and condensation takes place inside the inner tube or coil includes Liebig condenser,Allihn condenser,West condenser,Graham condenser. A graham condenser has a coolant-jacketed spiral coil running the length of the condenser serving as the vapor–condensate path.It consists of an inner spiral surrounded by an outer jacket tube.It maxmises collected condensate because all the vapors must flow through the entire length of the spiral,thereby having prolonged contact with the coolant. Graham condenser also called Inland Revenue condenser,usually used in the downward distillation or vacuum evaporations , installed vertically to prevent liquid pooling in the tube. It is very similar to the coiled condenser but differentiated by an inverted coolant/vapor configuration(the coolant flows through the inner coil and the substance condenses inside the outer tube). The liebig condenser is the most basic water-cooled condenser,also named “water conendenser”,which consists of an inner straight tube surrounded by an outer jacket tube,the cool water flows through the outer jacket to condensate the vapor in the inner tube.Water can asborb much more heat than the same volume of air,and its constant circulation through the water jacket keeps the condenser’s temperature constant,Therefore,a liebig condenser has a better cooling performance than an air condenser. A liebig condenser can be both used in a reflux and a distillation apparatus.In the reflux apparatus, the lower inner joint will be inserted into a round bottom flask which contains the mixture liquid,the upper outer joint may attach a dry tube to prevent atmospheric moisture from entering a reaction system. The Allihn condenser,also known as a “bulb condenser”,similar to a liebig condenser ,is designed with an inner tube consisting of a series of bulbs which increase the surface area availiable for vapor condensation surrounded by an outer jacket tube, the cool water flows through the outer jacket to condensate the vapor in the inner tube.Additionally,the Allihn condenser has a wider bore at the bottom and the condensed liquid can run down along the sides avoiding blocking the upward vapor. Allihn condensers are used for laboratory-scale refluxing and provide a greater surface area than similar Liebig condensers.A reflux apparatus usually consists of an Allihn condenser used as a reflux condenser,a round bottom flask(single neck or multi-neck),a drying tube to prevent the atmospheric moisture from entering into the reaction,a separatory funnel or pressure equalizing funnel for adding reagents. The flat bottom flask is likely the other round bottom flask but with a flat bottom allowing it standing up flat surface as the flask can sit upright on its own. Capacity of 250mL with 24/40 glass ground taper joint. It can be used in heading during distillation, they are not as durable as round bottom flasks for heating better than Erlenmeyer flask which has have the sharp and vulnerable corners. A flat bottom flask is used in chemistry laboratory for experiments involving collecting and measuring liquids, mixing solvent In a distillation apparatus,the flat bottom flasks can attach to a distillation adapter,liebig or allhnn condenser,take off adapter as a distillation or receiving flask.In a soxhlet extraction, a flat bottom attaches the soxhlet extractor used as boiling and receiving flask. Round-bottom flasks (also called round-bottomed flasks, Flasks, round bottom, or RB Flasks)having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. Because of the spherical bottom, cork rings are needed to keep the round bottom flasks upright,or heated by the water bath ,oil bath or sand bath.When in use, round-bottom flasks are commonly held at the neck by flask clamps on a stand. The flasks are usually used in heating or boiling a liquid, in distillation as distilling flasks and receiving flasks for the distillate, used as the distilling flasks in rotary evaporators.It is usually used with other jointed lab glassware like glass condenser,separatory funnels,cow receivers. The round bottom flask has larger heating surface than the flat bottom flask and can be heated evenly.It is usually used in the laboratory operation requiring high temperature and long time heating,or vacuum distillation. On top of the funnel-shaped part there is a cylinder with a fritted glass disc instead of filter paper.The liquid to be filtered is poured into the cylinder and drawn through the fritted glass disc by vacuum suction.With a jointed vacuum take off adapter at bottom, it has a lower standard taper inner joint and serrated hose connection to a vacuum source. A buchner funnel using vacuum suction for filtration can proceed filtration more quickly than common simple filter funnel via the force of gravity.It is commonly used in organic chemistry to collect recrystallized compounds.This buchner funnel with vacuum take off is usually used with a heavy wall Erlenmeyer flask. The glass frit disc plate on top of the funnel with the pore diameter from 10 to 20 micron .The outer diameter of the frit disc plate is 60mm.With 24/40 standard taper inner joint at the/ lower part and a side glass hose connection with 10mm O.D.at the largest serration.The capacity of the cylinder is 150mL. Round bottom design having spherical bottoms are more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface. A cork stand is needed to keep the round bottom flask upright,or heated by the water bath ,oil bath or sand bath.Comparing to the single neck round bottom flask,this 2 neck flask featured an angled neck with standard taper joint as an extra opening. The 2 neck round bottom flask is widely used in the organic chemistry process like distillation, reflux ,extraction,reaction etc.In a distillation apparatus,the 2 neck round bottom flask used as the distillation flask,the straight neck attaches a 3 way distillation adapter or a distillation column(in fractional distillation),the other neck can be used to connect a thermometer adapter ,bleeding tube, or additional funnel. This 2 neck round bottom flask has capacity of 1000mL, with 24/40 center joint & 24/40 side joint,attaching any lab glassware apparatus with standard taper joint. This three neck distilling flask designed with a round bottom and angled necks which allows to attach three lab glassware components for distillation apparatus( simple distillation,steam distillation,fractional distillation,azeotropic distillation).A cork stand is needed to keep the round bottom flask upright,or heated by the water bath ,oil bath or sand bath. Round-bottom flasks are often used to contain chemical reactions especially for reflux set-ups and laboratory-scale synthesis.It also can be used as a distilling flasks and receiving flasks for the distillate. This durable round bottom flasks with 3 necks, one center and two angled,with standard taper joints on the necks accommodating lab apparatus for multi purpose. It features heavy wall spherical body and 250mL capacity.Comparing to the single neck or twin neck flask,the 3 neck flasks have one more jointed neck for extra function,when it is not needed,the extra necks can be stopped by penny head glass stoppers. The separatory funnel is also known as separation funnel, separating funnel, or colloquially sep funnel,is a piece of laboratory glassware used in liquid-liquid extractions to separate the components of a mixture into two immiscible solvent phases of different densities. With shape of a cone and PTFE stopcock at bottom,and with a standard taper outer joint at Top,an inner joint at bottom. When adding regents during the reflux period,a separatory funnel can be used as a dropping funnel 250mL Pear-shaped separatory funnel with two 24/40 taper joints at both ends,also used as dropping funnel. This evapoaration flask is designed with low profile to sits upright on bench and also provides for easy product access with a spatula.This unique flask shape is ideal for controlling evaporation of foaming solvents on a rotary evaporator.
