Vacuum glove boxes are the most common airtight container used in laboratory and manufacturing work. They are usually used for sterility and safety purposes, like keeping samples safe or isolating hazardous substances. Vacuum handling is a crucial skill that should be part of any technician's repertoire, so get ready to learn strategies for safely using these tools.
Avoiding hazards associated with vacuum equipment can help protect your health and keep you out of trouble at work, but only if you follow some important steps first! Read on to learn more about preparing yourself before you use a Vacuum Glove Box.
Never reattach a cannula with force:
The cannula has been securely attached to the vacuum adapter, and you mustn't attach the tube back on in a different manner. Often, inexperienced users will get frustrated, and in an attempt to relieve tension on the tubing, they will twist or turn their hands to remove their hands from the glove box.
This action causes you to reattach your hand rather than just disconnect it. After experiencing this once or twice, you will quickly recognize what is happening and not reattach yourself under pressure.
Know your gauge:
You should also be able to identify your vacuum adapter's gauge by its color or size. For example, the gauge on a Bardstown v Vac-O-Matic is 12 gauge, and the gauge on a W&B adapter is 14 gauge.
The higher the number, the smaller and more compact your packer. If you are using a W&B adapter, you will need to remove about two inches of tubing from inside your glove box for it to work properly.
Know if the adapter you are using is rated:
All vacuum glove boxes are certified for use with a particular size or gauge cannula. You should check the instructions for your specific adapter carefully to ensure that it is certified for your cannula.
The non-certified adapters may not fit precisely and sometimes can even damage your vacuum tool. It is important to avoid buying adapters from other manufacturers or internet retailers that the FDA has not yet approved.
These are some of the guiding points that one must consider while using a vacuum glove box.
