Plastic and Glass Carboys – The Advantages
Laboratories have different chemicals being stored and handled in their daily operations. There are some which are flammable and there are also those that are corrosive and there are likewise others which are inert. One of the secrets of the safety of a laboratory would be to keep using the chemical containers which will help in minimizing risks. This is where carboy containers serve such functions.
The name of “carboy” originates back in the 1700s and this also comes from the Persian word as “Qarabah”, meaning large flag. Vessels like the carboy are made from glass and this is likewise covered with wicker or papyrus.
Carboys are also called demijohn. Today, this term is associated with wine and spirits. These actually are common products of the home beer brewers. However in laboratories, it’s more associated with chemicals.
There are actually various sizes that are available but only two main types are there, which is the plastic and glass. Both of such works well and there are also various advantages that it can offer.
Glass carboys are in fact the original form and it’s also used widely even today. These are also the standard because it could be used for a good reason. The primary reason as to why it’s a standard is due to the reason where it could be used multiple times and will not show any signs of wear.
The smooth surface of the carboy is non-porous which prevents anything from sticking to it. This has been found to be ideal when it comes to brewing because no chemicals or odor will transfer from one to another and the cleaning process is really easy.
A plastic carboy is an alternative to glass and the main advantage that it comes with is where it’s a lot lower in weight. An addition with the lightweight feature that it has is where you will get much better grip due to the polyethylene construction of which it has, which helps to make it much easier to handle. Polyethylene is likewise impermeable to air so there’s nothing to worry for any contamination or perhaps from too much evaporation.
Plastic carboys also have the potential of being dual-purpose. The plastic type likewise can be ported, which in fact allows the insertion of the spigot. This in fact makes it very useful when bottling. After the secondary fermentation is completed, you could bottle this directly from the plastic carboy with the spigot which takes away the need in transferring to the bottling bucket or in using a siphon.
Whatever the type that you are going to choose to use, a carboy could offer different advantages than the fermenting buckets could offer when it comes to the clarifying, fermenting and the conditioning process of homebrew.
