Everything You Need To Know About Vacuum Glove Box

The vacuum glove box is the original airtight enclosure and is still widely used today. The standard design of a vacuum glove box has a heavy steel outer frame that provides stability, insulation and physical strength. On one side of the frame are two doors, each with a gasket seal to provide an airtight sealing in conjunction with an o-ring at the base.

Inside the enclosure is a workbench or table with a rubber or silicone coated work surface. This coating helps to create an airtight seal against leakages from materials spilt in the glove box while being worked on.

Basic Structure of a Vacuum Glove Box

The gloves of the Vacuum Glove Box are made of stainless steel to support the frame and withstand exposure to harsh chemicals. Common seal materials include silicone rubber, silicone elastomer, EPDM rubber and natural rubber. In addition, many vacuum glove boxes have a safety interlock that ensures that both doors are closed before the vacuum pump can be started.

Both doors must be sealed and screwed shut with a pneumatic tool to ensure a strong airtight seal and enclosure is airtight. In addition, a pressure gauge is installed on the manifold where it can be easily monitored during use.

Working Process

When the vacuum pump starts, it removes air pressure from the interior of the glove box, and a small leak in the glove box will cause air to seep into it. This is known as saturation, and if this happens, an o-ring or gasket can be damaged due to a tightening of its size.

Therefore, when working inside a vacuum glove box, an inert atmosphere must be maintained by pumping inert gas. Any materials in the glove box should be assessed before being brought inside for any possible microbial contamination. The material is then placed into the glove box for a designated time before being checked for contamination.

The glove box is maintained by cleaning out any solvents that have been used in the material being worked on and replacing seals if necessary. A vacuum glove box has become a prominent part of every laboratory.

The Best Vacuum Glove Boxes: A Comprehensive Guide To Choosing the Right Product

A vacuum glove box is a fairly simple piece of equipment consisting of a vacuum chamber with gloves extending into it. A vacuum pump pulls the air out of the chamber, creating a low-pressure, low-moisture environment, and the gloves allow the operator to manipulate anything inside in the chamber.

Often this is combined with the re-introduction of inert gases into the chamber such as nitrogen or argon, allowing the operator to do experiments or perform other operations on the contents of the chamber in an inert atmosphere that prevents contamination with reactive gases like oxygen or liquids like water. This also adds an element of safety because an inert atmosphere is non-combustible. Most vacuum glove boxes are made out of acrylic, allowing the operator to easily see inside the chamber while they’re working on the chamber contents.

Vacuum Gauges for Vacuum Glove Boxes

Most vacuum glove box operates in rough vacuum (10-3 Torr up to 760 Torr or atmosphere), so any of our rough vacuum gauges are an excellent fit for a wide variety of vacuum glove boxes. For a standalone active gauge, check out the MX2A thermocouple or MX4A convection active vacuum gauges. If you’d prefer a rack mountable controller, check out the MV2A controller and the 2A passive thermocouple vacuum gauge.

Guidelines One Follow For Being Safe At Using Vacuum Glove Box

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.
