What is the difference between sterilization and commercial sterilization?
The difference is that commercial sterilization takes place in irradiation chambers and regular sterilization does not. A irradiation chamber can hold up to 50 tons and is sealed up before the high energy x-rays kills off anything living.
When did gas plasma sterilization begin?

What are the advantages and disadvantage OF THE different methods of sterilization?
Different methods of sterilization, such as steam sterilization (autoclaving), dry heat, chemical (gas or liquid), and radiation, each have their advantages and disadvantages. Steam sterilization is effective and quick but may not be suitable for heat-sensitive materials. Chemical sterilization is versatile and can penetrate complex instruments, but it may leave toxic residues and requires careful handling. Radiation is effective for single-use items but can be costly and requires specialized equipment.
Do you agree that eugenic sterilization should be allowed?
yes
Why are culture media not sterilized in hot air sterilization?
Culture media are not sterilized using hot air sterilization because this method primarily targets dry materials and is less effective for moisture-rich substances. The high temperatures required can degrade heat-sensitive components in the media, potentially compromising their effectiveness. Instead, autoclaving or steam sterilization is preferred for culture media as it utilizes moist heat to achieve effective sterilization without damaging the nutrients essential for microbial growth.
Is DMSO a protic or aprotic solvent?
DMSO is an aprotic solvent.
Is DMSO a strong nucleophile?
Yes, DMSO is a strong nucleophile.
What is the difference betwen DMSO and DMSO-d6 solution?
DMSO (dimethyl sulfoxide) is a common organic solvent, whereas DMSO-d6 is a deuterated form of DMSO used in NMR spectroscopy as a solvent. The "d6" indicates that the hydrogen atoms in DMSO have been replaced with deuterium, making it suitable for NMR analysis due to the absence of NMR-active protons.
Smell after using dmso?
DMSO can have a garlic-like smell when it reacts with compounds on your skin. This effect is temporary and should dissipate once the DMSO is fully absorbed or evaporated. It's important to use DMSO in a well-ventilated area to minimize the smell.
How to mix DMSO with water effectively?
To mix DMSO with water effectively, slowly add the DMSO to the water while stirring continuously. This will help prevent the DMSO from clumping or separating from the water. It is important to mix the two substances thoroughly to ensure a homogeneous solution.
What is size of DMSO molecule?
The molecular formula of dimethyl sulfoxide (DMSO) is C2H6OS. The molecular weight of this molecule is approximately 78.13 grams per mole. In terms of size, DMSO has a molecular diameter of about 6.9 angstroms.
Why is DMSO used as a control?
Many test compounds (drugs, inhibitors, etc) are not soluble in water and therefore dimethylsulfoxide (DMSO) is used as a solvent instead. The compound dissolved in DMSO is what is used to treat the cell or animal and therefore you must prove that it is the compound, not the DMSO which is causing any results seen. To ensure this, you have a control that contains only DMSO and not the test compound. This is often referred to as a "vehicle control".
What is the freezing point of DMSO?
The freezing point of DMSO (dimethyl sulfoxide) is 18.5 degrees Celsius (65.3 degrees Fahrenheit).
What is the significance of the azeotrope formed by dimethyl sulfoxide (DMSO) in chemical processes?
The azeotrope formed by dimethyl sulfoxide (DMSO) is significant in chemical processes because it allows for the separation of DMSO from other substances through distillation. This is important in various industries, such as pharmaceuticals and organic synthesis, where the purity of DMSO is crucial for the desired chemical reactions.
How do you make large clear DMSO crystals?
DMSO (dimetylsulf oxide) (CH3)SO is a liquid with the freezing point at 19 oC.
What are the possible impurities in dmso?
Possible impurities in DMSO (dimethyl sulfoxide) can include water, dimethyl sulfide, dimethyl sulfone, acetone, and other organic compounds. These impurities can affect the stability and purity of DMSO, altering its properties and potential uses. Regular purification methods such as distillation or filtration are typically used to remove impurities from DMSO.
Advantage of online sterilization over batch sterilization?
Online sterilization offers the advantage of real-time sterilization, meaning products are sterilized as they are processed without the need for storage between processing and sterilization. This reduces the risk of contamination or recontamination after sterilization, as products are immediately enclosed in a sterile environment. Additionally, online sterilization allows for more flexibility in production scheduling and can lead to overall cost savings by reducing inventory and processing time.
