Specialty Gases & Equipment – How to Build a Regulator
January 9, 2021 by middlesexgases

Pressure regulators (often just called regulators) are used in a gas system to reduce the pressure from a high pressure source, such as a compressed gas cylinder or a gas supply pipeline, to a safe level consistent with the pressure rating of the system to which the gas is being supplied. They provide positive control of the source pressure in a gas system. This control of pressure permits better control of flow rates and helps to provide a safer operation.

Selecting Lab Gases
October 19, 2020 by middlesexgases

There are a number of gases that can be delivered in portable cryogenic vessels for gaseous or cryogenic use but for the purposes of this article we will be discussing the operation of a portable liquid nitrogen vessel. First, it is the responsibility of the end user to be thoroughly familiar with the operation of the vessel and the limitations of the vessel performance. This starts with ordering the vessel. Some vessels are intended for liquid use only, some will deliver gas and/or liquid and some are intended for higher pressure gas use.

Keeping Abreast of the Helium Market
October 26, 2019 by middlesexgases

We hope everyone enjoyed their Thanksgiving holiday. If you were fortunate enough to watch the Macy’s Thanksgiving parade then you no doubt were in awe of the magnificent balloons soaring five or six stories high. These balloons are, of course, filled with helium gas — 300,000 to 700,000 cubic feet (the equivalent of over 2,400 high-pressure cylinders) of the precious gas per balloon. The next time you see one of these balloons you may have different feelings knowing the cost of the gas to fill the balloon was in excess of $500,000 per balloon.

Liquid Nitrogen Dispensing
October 23, 2019 by middlesexgases

There are many occasions in the lab workplace for employees to take on the task of dispensing liquid nitrogen. There are some simple guidelines that should be followed when handling this hazardous product.
Liquid Nitrogen (LN2) is an inherently dangerous product to handle for a number of reasons but the most obvious one is its temperature. At -321 F this product will cause rapid frostbite upon contact with the skin. Splashing LN2 can cause serious and permanent eye injury.

Carbon Dioxide Caution
October 22, 2019 by middlesexgases

In many labs, carbon dioxide (CO2) is used for varied purposes. In many cases, CO2 is used to feed incubators in an isolated room. The CO2 is commonly piped into the room from a liquid CO2 source located elsewhere. Caution should be used in this case as all too often an end user with the best of intentions will install an oxygen depletion monitor in this area presuming to detect a leak of CO2.

How Valuable is Your Time?
October 20, 2019 by middlesexgases

This question is worth more than a quick answer so ponder it for just a moment and place yourself in the middle of your workday busy with your science and its many tasks. Now stop what you are doing and pick up a wrench and go change an empty cylinder for a full one. Shut the empty tank off, remove the pressure regulator, retrieve a full tank from the stock pile, un-strap the empty cylinder and replace the tank, replace the regulator, re-set the delivery pressure etc. etc.

Service Provider
October 16, 2019 by middlesexgases

Is your current gas supplier a service provider or do they simply deliver gases? Companies separate themselves from one another by a number of means. Commonly, they depend on pricing to speak to the difference in their company philosophy. At Middlesex Gases & Technologies, while our product is competitively priced, we would prefer to let our service differentiate us from the rest of the pack.
