SDSs vary by country.Humidifiers are a staple in many American households, if for no other reason than they make you feel better when you're sick. When you or your children are suffering a cold, it's often the humidifier to the rescue, adding moisture to the air to help with sore throats and congestion. When you live in a dry climate, a humidifier is an invaluable way to make your home more comfortable. Of course, heading to the store to actually purchase a humidifier might have you scratching your head. There are plenty of different types and features to choose from, and when you get it home   then what?

This quick walkthrough some basic humidifier features will give you a better idea of what you need and the best way to make it work for you.A cool mist humidifier works best in areas where you struggle with hard water. The cool mist process is less prone to getting hard water buildup on the wick and filter portion of the machine. Additionally, the cool mist assembly traps the minerals in the hard water so they don't permeate the air where you can then breathe them in. oreck proshield® plus air purifier reviewsCool mist humidifiers are also ideal for children because they don't pose the same burn risk that hot vapor humidifiers do, so you can leave them in your child's room all night without worrying.sharper image air purifier gp model ionic breeze w germicidalIf your water is soft, you can try a warm mist humidifier in place of a cool mist one. lowyat forum air purifier

Some users prefer the comfort of a warm mist humidifier; the vapor that comes out of the machine is warm and wet, which can really help moisten the air and make a difference when it comes to cold symptoms. However, warm mist models are more prone to getting clogged and dirty with minerals found naturally in harder water, so it's best to use them if you have a water softener. Most warm mist units function by boiling water and releasing the vapor as steam, which kills bacteria and spores. These humidifiers make for a healthier and more comfortable night's sleep.If you're worried about the noise that a humidifier makes, you might want to consider using an ultrasonic model instead. Ultrasonic models work by using high frequency sound waves to break down the moisture particles and disperse a fine mist. The mist is so fine that it can look more like fog than mist. Since the particles are so small, some users have reported seeing a white powder on their furniture afterward   a result of using hard water with an ultrasonic model.

Switch to distilled water, and you'll eliminate that issue, since distilled water has been boiled to remove all bacteria and minerals from the water.Aseptic liquid products perfectly dosed in very small quantities. The aseptic dosing station VARI-DOS-ASEPT provides a safe and reliable way to dose small quantities of up to 0.2 – 3 g/kg of aseptic liquid products directly into the main aseptic product flow. Aseptic dosing helps to achieve best product quality at competitive costs. The product to be dosed is provided in aseptic containers similar to those used in the pharmaceutical industry. The container consists of a pharmaceutical bag and a hose that is firmly connected to the bag. A dosing needle is fitted to the tip of the hose. Bag, hose and needle have been previously sterilized. The empty hose is connected to the aseptic filling line upstream of the aseptic filler via the needle and a special aseptic multi-function port valve. Two port valves are provided so that production can run continuously.

The aseptic port valve allows automatic sterilization of all parts in contact with product at a temperature of more than 125 °C. The port valve is switched to the sterilization position by compressed air and is then sterilized by steam passing through them. The needle remains in the sterilization position, and the front third of the needle is also sterilized. Filtered, and thus sterile, compressed air automatically cools down the port valve to less than 50 °C after sterilization. The dosing station has a filling capacity of 6 – 12m3/h and can be equipped with bag sizes of 5 and 10 kg. Are you at the right place? Please review the detected settings Choose a GEA location Congo (Democratic Republic of the) Cell Culture Basics — Gibco Successful cell culture depends heavily on keeping the cells free from contamination by microorganisms such as bacterial, fungi, and viruses.  Nonsterile supplies, media, and reagents, airborne particles laden with microorganisms, unclean incubators, and dirty work surfaces are all sources of biological contamination.

Aseptic technique, designed to provide a barrier between the microrganisms in the environment and the sterile cell culture, depends upon a set of procedures to reduce the probability of contamination from these sources. The elements of aseptic technique are a sterile work area, good personal hygiene, sterile reagents and media, and sterile handling. View our Aseptic Techniques Checklist The steps to prevent contamination of your cell culture and demonstration of best-practice sterile techniques. The simplest and most economical way to reduce contamination from airborne particles and aerosols (e.g., dust, spores, shed skin, sneezing) is to use a cell culture hood. The cell culture hood should be properly set up and be located in an area that is restricted to cell culture that is free from drafts from doors, windows, and other equipment, and with no through traffic. The work surface should be uncluttered and contain only items required for a particular procedure;

it should not be used as a storage area. Before and after use, the work surface should be disinfected thoroughly, and the surrounding areas and equipment should be cleaned routinely. For routine cleaning, wipe the work surface with 70% ethanol before and during work, especially after any spillage. You may use ultraviolet light to sterilize the air and exposed work surfaces in the cell culture hood between uses. Using a Bunsen burner for flaming is not necessary nor is it recommended in a cell culture hood. Leave the cell culture hood running at all times, turning it off only when they will not be used for extended periods of time. Wash your hands before and after working with cell cultures. In addition to protecting you from hazardous materials, wearing personal protective equipment also reduces the probability of contamination from shed skin as well as dirt and dust from your clothes. Sterile Reagents & Media Commercial reagents and media undergo strict quality control to ensure their sterility, but they can become contaminated while handling. 

Follow the guidelines below for sterile handling to avoid contaminating them.  Always sterilize any reagents, media, or solutions prepared in the laboratory using the appropriate sterilization procedure (e.g., autoclave, sterile filter). Always wipe your hands and your work area with 70% ethanol. Wipe the outside of the containers, flasks, plates, and dishes with 70% ethanol before placing them in the cell culture hood. Avoid pouring media and reagents directly from bottles or flasks. Use sterile glass or disposable plastic pipettes and a pipettor to work with liquids, and use each pipette only once to avoid cross contamination.  Do not unwrap sterile pipettes until they are to be used.  Keep your pipettes at your work area. Always cap the bottles and flasks after use and seal multi-well plates with tape or place them in resealable bags to prevent microorganisms and airborn contaminants from gaining entry. Never uncover a sterile flask, bottle, petri dish, etc. until the instant you are ready to use it and never leave it open to the environment.
