We buy sterile DMSO from sigma. It comes in sealed glass 10 ml vials. I work with some very hydrophobic compounds that I add to media. I dissolve the compounds in the sterile DMSO & just add it to media. In 2 years, I haven't had any contamination. But my compounds are kind of toxic at the stock concentrations. This looks like what we use.Autoclaving is an efficient and effective sterilization method for labs, breweries, dentist offices, tattoo parlors, and other places that consistently need sterilized items. However, while autoclaves are effective for many materials, some articles are either unsafe in the autoclave or will degrade when subjected to heat, pressure, and steam.Read 3 answers by scientists to the question asked by Pedro Rodrigues on Apr 23, 2021
The preferred sterilization for DMSO method has become sterile filtration using 0.22 μ filters and, importantly, in DMSO compatible housings. A difficulty arises during the sterilization of viscous DMSO formulations, such as devices based on solutions of medical polymers. This issue may require the manufacturer to compound separately .
Preparations to be sterilized by dry heat are filled in units that are either sealed or temporarily closed for sterilization. To sterilize mineral oil I use a flask with aluminum foil lid (2hs x .
3. When organic solvents are used (e.g. DMSO), it is better to use cell culture grade (e.g. Hybri-Max) as they are endotoxin free. 4. Use sterile, depyrogenated glassware, pipets and other consumables, reagents and equipment. Whenever possible use disposable tools. 5. To depyrogenate glassware and other tools which can tolerate high . Quality steam is vital to a successful autoclave sterilization process. The steam used for sterilization should be composed of 97% steam (vapor) and 3% moisture (liquid water). This ratio is recommended for the most efficient heat transfer. When the steam moisture content is less than 3%, the steam is described as superheated (or dry).
It is generally recommended to filter DMSO rather than autoclave it. We recommend using ATCC DMSO, which is a ready‐to‐use sterile filtered solution. What is the best method to thaw bacterial stock from cryopreserved stock? Thawing frozen bacterial stock can be done using the same method as thawing animal cells, using a warm (often 37°C . Adhering to proper procedures, understanding compatible and incompatible materials, and ensuring regular autoclave validation are essential for the successful and safe use of autoclaves. With the knowledge gained from this guide, you are now equipped to utilize autoclaves effectively and contribute to the maintenance of a clean and sterile laboratory .The reagent that I am most suspicious of is a common stock of 99% DMSO. There is work with sporulating bacteria going on in my lab, so I am wondering if there could be spore contamination in the .DMSO is not autoclavable in neat form. It is highly unlikely that microorganisms would survive in this environment. Should sterilization be necessary a PTFE, Polypropylene, or Nylon filter membrane are recommended for sterile-filtration.

With heat-stable articles, the approach often is to considerably .
This autoclave provides high-performance, high-capacity steam sterilization for a broad mix of instrument sets and medical devices. How Does the AMSCO ® Evolution Medium Steam Sterilizer Work? The AMSCO Evolution Medium Steam Sterilizer unique chamber shape promotes even pressure and heat distribution within the medium autoclave.
Autoclave sterilization standards and directives permit some flexibility in steam humidity levels, since it’s almost impossible to supply perfect steam at a steady flow. Even if conditions are nearly optimal, many variables affect steam as it’s transferred to an autoclave. Chief among them: weather conditions and temperature; piping quality . Sigma supplies sterile filtered DMSO in small 5 ml glass vials (Cat.#D2650). . -Louie-no need to autoclave DMSO..-Casper-I see.
