When You Need a Vaporizer: Short answer: If the demand of gas needed (also known as flow rate) is higher than the output of a liquid cylinder the pressure and flow rate will drop. Adding a vaporizer to the liquid cylinder increases the flow rate of the liquid cylinder while keeping the same pressure. Meaning the flow rate and pressure stays constant. Longer explanation: A typical 160 liter cryogenic liquid container with a medium pressure has an output of about 350 standard cubic feet per hour of liquid nitrogen. After the first hour of operating, the output of the dewar starts to slow because the container becomes cold. Warm air allows the container to convert the liquid into gas quickly. The lack of warm air drops the output of the tank after the 1st hour of use. If more than 350 standard cubic feet of liquid nitrogen is needed per hour, the dewar would be unable to keep up with the demand. The tank would start to over draw the vaporization. A scenario such as this is when you would use a vaporizer. A vaporizer allows you to continue to convert liquid into gas for long periods of time as oppose to being limited to a liquid cylinders standard output. If customers need a higher flow rate, a vaporizer can be attached to the liquid container and will generate a higher flow rate for a longer period of time.

Why Number Medical Labels? If the FDA audits a company, the company would need to be able to communicate how many labels they have used, how many they have in process that day and how many they have in storage. As a part of the inventory process it is a requirement to keep a log of labels used. By having the labels sequentially numbered on the back of the labels is a great aide in helping companies guarantee how many labels were printed per roll and how many are left on that specific roll. When a company receives rolls from the label supplier they can verify the individual count of each roll and tally total numbers being added to they inventory quite easily by reading the numbers on the backs of the labels. Serializing labels can also be a good check and balance for that day’s activities to say they started with label number “x” and the roll now shows we have “Y” labels left . It allows a company to see the log sheet, for example, “ I used X-Y labels today so I accounted for everything.” There is no requirement to have this sequential numbering on the backs of the labels, it is purely up to each company to define the practices they want to adopt for accounting for these labels, the sequential numbering is simply a tool companies can use as a checks and balance process.

1.Ensure threaded end of valve body is clean and free of any debris 2. Place end of locking bracket over end of outlet valve. 3. Tighten the CGA fitting finger tight. The formed square section of the locking bracket must be guided to slide over the valve body. 4. Insert an Allen wrench into the center of the CGA fitting and tighten the connection into the valve body thereby pulling the locking bracket over the valve body. 5. The connection is installed and ready for safe use 6. If desired, pressurize connection and spray a liquid leak detector into the sight windows and look for leaks. How to Porperly Remove a TPG Place blade on the saw in between the end of the bracket and the fitting body. Cut down completely though the fitting body. The gap will act as a guide for the blade. 2. Grasp the locking bracket and pull straight out over the remaining fitting stud. If necessary, gently tap the bracket off with a hammer. The clutch mechanism will fall apart allowing the locking bracket to be removed. 3. Place a pip wrench on the remaining stud and remove the partial fitting, leaving the thread of the valve body intact for replacement with the TPG device. 4. The CGA fitting, locking bracket and clutch mechanism will be completely unusable.
Atmospheric gas packaging is a growing technology that is done by manipulating gases to remove oxygen from a high barrier or permeable package. It is achieved by using inert gases including nitrogen, carbon dioxide, and exotic gases such as argon or helium to inject and remove multiple times to eliminate until the oxygen is eliminated. It is also known as modified atmosphere packaging, protective atmosphere packaging, reduced oxygen packaging, and gas flushing.
