PureAire Releases Universal Toxic Gas Monitor

PureAire Monitoring Systems manufactures and distributes toxic gas monitors for safety, and as of August 2013, releases new toxic gas monitor called the Universal Toxic Gas Monitor. Their monitors make sure areas where toxic gases exist the area remains at a safe and breathable level, some gasses included are chlorine, bromine, HCL, HF, ammonia, toxics, and hydrides. These gases, commonly known as toxic gases, can be hazardous or even deadly if used without the proper safety precautions. Typical areas where these gases are used include laboratories, pharmaceutical manufacturing plants, cryopreservation facilities, semiconductors, and cold food storage. The addition this product line insures PureAire’s products are the premium choice for your safety. Since their beginnings in 1997, PureAire has sold many thousands of toxic gas monitors to customers including (Northwestern University, Exxon Mobil, and NASA) and laboratories (Intel, Los Alamos National Labs, USDA). A release of toxic gases in a confined space can cause irritation, permanent damage, and even hospitalization making it direly important that every space with human occupancy be monitored. Though these gases can be highly dangerous, their universal gas monitors allow groundbreaking research to be done with the ease of knowing any leak will be immediately detected. PureAire Monitoring Systems provide the #1 universal toxic gas monitor in the industry. With a renewable sensor lasting 7+ years, no competitor can offer the same longevity or reliability. The universal gas monitor has a built in audible alarm, 2 user-selectable relays for signals to external fans/horns/strobes, and a 4-20 mA signal. The introduction of the universal gas monitor provides a newer easier solution for the customer. Still used is the STX-PA Smart Gas Transmitter, though PureAire is predicting the universal gas monitor will take the STX-PA’s place. Manufactured in the USA, there is no question they are the unparalleled company to go to for your toxic gas monitor safety needs. The STX-PA has been sold since PureAire started in 1997 along with there 4-20mA version Aircheck Lite, also trying to be replaced by the universal toxic monitor. As with most technology, a newer updated version of a product is necessary. While the universal monitor has many of the same functions as the STX-PA this product offers more. Integrated is software enabling the customer to change the sensors by a simple plug and play. If the customer has testing which requires using HF for a few days but needs to switch to chlorine for another experiment, he/she can simply unplug the HF sensor and replace with chlorine in matter of seconds. The STX-PA would also have capabilities of switching sensors, though sending in the monitor PureAire had to take place in order to switch. In addition to many more features listed for the universal monitor, now there is a considerable louder 90 dB audible alarm. Lastly, pricing is much more competitive starting at $1,390 for a complete system compared to a starting price of $1,990.

Liquid Nitrogen in Human Oocyte Cryopreservation

The word cryopreservation sounds like something from a science fiction movie. Maybe a man from the past was frozen in time, only to reawaken decades later, unharmed and unaware that he had been frozen at all. Though this scenario seems far-fetched, on a smaller scale, cryopreservation is a commonplace practice in the 21st century. While a grown man cannot be frozen and awoken, the building blocks of man are fair game. Human oocyte cryopreservation, or egg freezing, is a way to freeze and preserve a woman’s eggs. At a later time, these eggs can be thawed and fertilized and used to impregnate the woman. There are many reasons a woman may be a candidate for this procedure. Some of these reasons are age, early menopause, and pre chemotherapy or radiation therapy, which may damage eggs left in the body. In any case, if a woman learns that she will be unable to produce healthy, viable eggs in her future, oocyte cryopreservation is a good option to ensure she has healthy eggs if she decides to try conceiving at a future time. Semen and embryos can also be treated and cryopreserved in a similar way. These specimens can remain frozen for a long period of time. Embryos can be stored for up to 16 years, and semen as long as 22 years. This allows someone who is going through an illness or separation from a spouse to wait until a more viable time for implantation for conception. Most people can easily understand the concept of freezing something to save for later, but the frozen eggs are not stored in your average icebox. Instead, liquid nitrogen freezes the eggs at −321 Fareignheight. This temperature is considered a deep freeze. With the addition of a cryoprotectant to deter ice crystals from forming, the specimens remain in the deep freeze until they are thawed for later use. Amazingly, over 500,000 live human births have been a result of such technologies. There are over 400 facilities nationwide that can provide the oocyte cryopreservation procedure to women in need. On the patients end, the facilities seem like ordinary doctors offices, but the real magic takes place behind closed doors. The scientists and lab technicians use liquid nitrogen to conduct the deep-freezing, which can be very toxic if not used correctly. They rely on oxygen deficiency monitors to detect any lower than average levels of oxygen in the vicinity, which may indicate a nitrogen leak. For the whole sequence to go off without a hitch, the scientists need to remain confident in their safety throughout the process. Pureaire Oxygen Monitoring Systems has created the perfect product to ensure such safety. Their O2 monitor is the best in the industry. The zirconium oxide sensor in the monitor lasts 10+ years with no maintenance or recalibration, making the product last longer than any other. This makes the monitor very cost effective, as it does not require additional purchases on a yearly basis. Also, the monitor’s ability to link to an alarm system, horn and strobe, and exhaust fan help warn people across a facility to evacuate an unsafe area. There is no question that today’s scientific technologies are impressive, yet ever evolving. As a company, Pureaire Oxygen Monitoring Systems vows to support these growing technologies by keeping researchers safe and giving them the confidence to do their job creating families of the future.
