We sell standard taper, o-ring, and ball & socket joints through our retail web site, Safety Emporium. The joint size is described by a number of the form xx/yy. The first number denotes the outside diameter of the top of the tapered male joint (or inside diameter of the top of the female joint) and the second number denotes the length of the joint. For example, a 14/20 joint (pronounced "fourteen-twenty") is 14 mm wide at the top and is 20 mm long. 19/22 and 24/40 (shown above) are two other very common joint sizes. As each joint has a standard taper, any two joints with the same outside diameter can fit into each other as long as the apparatus to which they are attached does not interfere. For example, a 14/35 joint on a condenser will fit into a 14/20 flask but the ground glass joint will protrude (35 - 20) 15 mm into the flask. Separation funnels and volumetric flasks typically use a "stopper" size, not standard taper joints. A few enlightened manufacturers do sell such equipment with standard taper joints. When in doubt, look for the standard taper symbol on the glassware: One drawback to standard taper joints is that they may sieze or "freeze". This usually happens when the joint is not properly greased (see below) or material is caught between the two halves of the joint. Your local glassblower can help [read these stuck joint tips if you don't have a glassblower]. To provide protection against accidental separation of the joint while in use (potentially exposing your reaction to air or releasing the contents to the laboratory), the assembled apparatus should ideally be secured with joint clips. Most laboratories these days use Keck™-style plastic clips which snap over the joint and hold the connection firmly in place.
The connection is strong and secure, but will yield under pressure so as not to create an explosion hazard. The only drawback to these plastic clips is that they are unsuitable for temperatures above. Clips are sized to a particular joint diameter, so if you lab uses 14/20, 19/22 and 24/40 equipment you will need to purchase three different size clips. Our retail division, Safety Emporium, offers nine different sizes of plastic clips at competitive prices. These work identically to the plastic clips and will withstand higher temperatures, however they run the risk of scoring and scratching the joint. They are also more expensive (but more durable) than plastic clips. Springs generally have more holding power than plastic Keck™ clips if the joint needs to support weight (for example, if one is suspending a storage vessel to a vacuum line). Our retail division, Safety Emporium, offers springs as well as hooked joints, flasks and adapters. On the right, we see a distillation receiver that is equipped with springs. A common question is "Do I need to grease these standard taper joints?" If you are doing simple organic chemistry and you are not heating the material, then the answer is generally "No." But if you plan to heat your materials, you need to make sure that air and water are excluded from the system, and/or you want to make sure the joint does not freeze, then you must do so.
The grease you select will depend on the nature of your experiment. For routine work, a simple silicone grease will be fine. For high vacuum applications, more expensive greases such as Apiezon H or M grease should be used. To grease a joint, first make sure that both the inner and outer halves are completely clean and free of old grease or particulate matter.
