We hope this brief crash course in science lingo helps you to sound smarter among your peers. Both are used during chemical reactions, and both are essential to a successful lab. Both are made from either glass or clear plastic, most are graduated- meaning they have markings on the side indicating the amount of liquid they contain. The spout on beakers makes pouring their contents easy, which makes them invaluable for performing experiments.įlasks and beakers do share some characteristics. Beakers are mainly for measuring and transporting liquids from one site to the next. The main differing characteristic between a flask and a beaker is that beakers have straight sides, rather than slanted sides like a flask. These are also used when performing experiments, to hold various liquids for either mixing or disposal. Furthermore, flasks have the ability to be capped or corked, therefore solutions can be held for long periods of time without risk of spilling.īeakers, on the other hand, are cylindrical containers with a flat bottom and a spout on top. Flasks are normally the site of chemical reactions, for the reaction can take place in the large vessel and have low risk of spilling due to the long, narrow neck of the flask. Flasks can be used for holding and measuring solutions, as well as for chemical reactions and phase changes (heating, cooling, etc). While both tools are often used in a science lab, they are actually quite different.įlasks are notable for their unique shape: a rounded vessel and a cylindrical neck. Many people outside the science world use the terms ‘flask’ and ‘beaker’ interchangeably. If people are becoming really interested in your middleware, and are willing to help, think about converting it to an WSGI middleware library so that it can be used in other frameworks.Sorting through nerdy jargon: how to sound like a real scientist.If you think your middleware is useful in a few of your apps, and might be helpful for other people, still use the middleware of your framework (what Flask would really typically call an "extension").The beaker volume marks are stamped onto an approximately round container and are often off by as much as 20 You were. If you are just writing a middleware that does something specific to your application, use the middleware of your framework. The volumetric flask is designed and built to reproduce an accurate volume.The maintainer of the library specifically made sure that the library could work in multiple frameworks, so he wrote it as a WSGI library.īasically, this is how I would make my decision: If it were written specifically in Flask, then Pyramid developers couldn't use it. For example, Beaker is a session and caching WSGI middleware that could be used in any WSGI framework. One advantage that creating a WSGI middleware has is that it can be used in multiple frameworks. By using the Django middleware, your middleware works on both systems (see this post by James Bennett). One reason is due to the fact that Django was designed to work equally on mod_python and WSGI. The reason you don't have confusion there is because the Django community typically steers developers away from WSGI middleware. Django, in some part, is built on WSGI, so you could theoretically write WSGI middleware or Django middleware in Django as well. Actually, you have the exact same choice in Django.
