What is the shelf life of powder ATP Adrenisine Triphospate compared to that which has been constituted?
If you are wondering about ATP (Adenosine Triphosphate) some reports say only 3 freeze-thaw cycles, for example if you are doing a ligation reaction, you will see inefficiencies in ligation after three cycles. The powder form of ATP will be good if kept in a stable temperature and free from impurities. Our lab, upon reciept of aqueous ATP (10mM), makes freezer stocks at 10ul. This allows us to remove single partitions for use and only thaw two times.
What else can I help you with?
What is hypothesis of powder coating?
The hypothesis of powder coating is that applying a dry powder paint to a surface and then curing it with heat will result in a durable and attractive finish. This process is believed to provide better coverage, adhesion, and resistance to chipping and fading compared to traditional liquid paint methods.
What does non alkalized mean?
Non-alkalized means that the cocoa powder has not been treated with an alkalizing agent (such as potassium carbonate) during processing. This results in a cocoa powder with a more acidic and complex flavor profile compared to alkalized cocoa powder.
What has the larger surface area a lump of chalk or chalk powder?
Chalk powder has a larger surface area compared to a lump of chalk. This is because the process of grinding chalk into powder increases the total surface area exposed to the surrounding environment. As a result, the smaller particles of chalk powder provide more surface area for reactions, interactions, or absorption than a single lump of chalk.
Would carbonates react faster as lumps or as powder?
Carbonates would generally react faster as powder compared to lumps due to the increased surface area available for the reaction to occur. More surface area allows for more contact between the reactants and speeds up the reaction process.
Is Charcoal powder chemically inert?
Charcoal powder is not completely chemically inert because it can react with certain chemicals and substances. However, its reactivity is generally low compared to other compounds, making it a commonly used material in various applications such as in purifying water and absorbing toxins.
Is gold powder still a solid?
Yes, gold powder is still considered a solid substance. It may have a different physical state compared to a solid bar of gold, but gold particles in powder form retain their solid properties.
What is the by product of cocoa processed with alkali?
The by-product of cocoa processed with alkali is known as alkalized cocoa powder, or Dutch-processed cocoa powder. This process results in a darker color and milder flavor compared to natural cocoa powder.
Is there alternatives to measure the electrical resistance of powder without having to compress them?
I am not 100% sure, but if you add the powder into a aqueous solution contaning electrolytes and compared the conductivity before and after you added the powder into the aqueous solution, it may display a difference in conductivity.
Which has a larger surface area powder or lumps?
Powder typically has a larger surface area compared to lumps because the fine particles in powder allow for more surface area to be exposed. This increased surface area can be advantageous for processes like absorption or dissolution.
How does black powder compare to smokeless powder in power?
Black powder is much weaker than smokeless powder. Smokeless powder, for this reason, once invented(much after black powder), replaced black powder in guns. However, black powder is still used in fireworks because the extreme explosive power of smokeless powder would prove too dangerous in fireworks.
Where could you buy injectable ATP Adenosine Triphospate powder in the US?
Only place I have seen it, is for veterinary use. It's really a big thing in Australia, horses and grey hounds for racing. They use it before a race, or after for recovery. Check Veterinary supplies in the U.S. for it, some in the U.K. will sell it for around $30 for 50ml, usually 1-3 ml per 200lb person.
What is loose powder foundation?
It's basically just makeup in a powder form. Just like your regular pressed powder, that's not pressed. It's used after your foundation to set your makeup and to create a more natural, flawless look compared to that of pressed powder. Pressed powder is more for you to use when you're on-the-go and to keep in your purse.
What is hypothesis of powder coating?
The hypothesis of powder coating is that applying a dry powder paint to a surface and then curing it with heat will result in a durable and attractive finish. This process is believed to provide better coverage, adhesion, and resistance to chipping and fading compared to traditional liquid paint methods.
How much salt in a teaspoon of baking powder?
There is approximately 300-400 milligrams of salt in a teaspoon of baking powder, depending on the brand and formulation. This amount is relatively small compared to the daily recommended sodium intake for adults.
How does powder coating differ from liquid painting?
Powder coating typically leaves a thicker layer of paint on a surface compared to liquid paint. It is also tougher, harder to remove spots of and is less permeable by water and pollutants.
How much is 5 tbs of cocoa powder compared to chocolate squres?
3 level tablespoons of cocoa powder plus 1 tablespoon of butter or shortening equals 1 square cube of unsweetened baking chocolate.
What does non alkalized mean?
Non-alkalized means that the cocoa powder has not been treated with an alkalizing agent (such as potassium carbonate) during processing. This results in a cocoa powder with a more acidic and complex flavor profile compared to alkalized cocoa powder.
