A Few Extra Tips
A Few Extra Tips Here are a few additional useful “hints” for making great connections.
How do I adapt? With the long list of manufacturers creating equipment, and with all the different variations on tubing size and threaded port configuration, scientists will frequently need to find adapters to make a special tubing connection.
Or Will They? Ironically, while many people might approach making a connection with an adapter, frequently adapters are unnecessary. To better understand this, let’s distinguish between adapters and their counterparts – unions. Basically, adapters “adapt” between two different types of thread/port configurations, while unions have the same thread/port configuration on both sides. To illustrate this point, Figure 20 shows various connectors and classifies them as either adapters or unions. Before continuing, it’s important to establish one general “rule of thumb”: Unions are typically less expensive than adapters while often performing equally as well. Therefore, wouldn’t it make sense to use a union wherever possible?
