Any heat much over room temperature at that point would denature the cells due to the water content on the slide. Even if it was gentle, the heat from the flame would be enough to sizzle them like tiny fried eggs. :)
Air-drying smears before heating is essential because it allows the cells to adhere firmly to the slide, preventing them from coming off during the heating process. This ensures that the cells are evenly distributed and fixed to the slide, resulting in a clear and accurate staining. Additionally, air-drying helps to remove excess water from the sample, which can interfere with the staining process.
You can add a drop or two of essential oil into the pad before heating. Lavender is a very popular one for its calming effect.
An annealer is a device or process which anneals - hardens by the process of greatly heating an object before cooling it slowly to render it less brittle.

Heating a sample before placing it in a muffle furnace helps to remove any moisture or volatile impurities that could affect the results of the heating process. This pre-heating step ensures that the sample is dry and clean, allowing for more accurate and consistent results when it is heated in the muffle furnace.
Copper Sulphate crystals before heating r blue....but after heating I dunno , may be u should try and ask your Sci.Miss/Sir I'll get back when I get the other answer .
The process of molten material involves heating a solid substance to its melting point, causing it to turn into a liquid state. This can occur through various methods such as heating in a furnace or using a torch. Once in a molten state, the material can be manipulated or molded into different shapes before it solidifies again upon cooling.
You should test run any heating system well before you need it to heat an premises. That way if you have any essential maintenace after a long close down you have time to get an engineer in.
Heating citric acid before titration is done to help dissolve the solid citric acid more effectively in the solution. This ensures that the titration reaction occurs uniformly and the results are accurate. Additionally, heating can also help increase the rate of the reaction, making the titration process faster.
DNA is copied during a process called DNA replication. This essential process takes place before cell division and ensures that each daughter cell receives an exact copy of the genetic information.
your scene of touch can help you tell how hot or cold an object is.
You are not so much as heating tubes but preventing unwanted microbes from "sneaking" into the culture. You are sterilizing the mouth of the tube before and after.
