Dropped Mercury thermometers account for almost half of the spills that occur each year on campus. Rarely do people have the mercury spill kit required to clean up the half a gram of mercury that can escape from these thermometers. If someone drops a mercury thermometer in your lab, you lose time, money, and possibly your clothing or equipment. Instead, recycle your mercury-filled thermometers through EH&S and we'll deliver a free alcohol-filled thermometer in exchange. Our alcohol thermometers are semi-submersible and measure from -20 to 110ºC to within 1º. They perform most routine laboratory functions that mercury thermometers are used for, such as measuring the temperature of water baths or ambient air. And best of all, when you drop one, all you have to do is wipe up the liquid with a paper towel and throw it away, and place the broken glass in your lab glass bin.
What else can I help you with?
Would it be better to cool a soda faster in the freezer or fridge?
The Freezer.
Is a frost free freezer better than a normal freezer?
Frost-free freezers will keep down the moisture produced by your refrigerator. They also enable a larger amount of space in the freezer compartment by preventing moisture to encompass the areas around your freezer.
Would glass or plastic shelving be better in a freezer and can you explain your choice?
Plastic shelving would be better in a freezer than glass because the extreme cold would make the glass more brittle and thus more likely to break.
Where would the doctor place the clinical thermometer to take your body temperature?
use a thermometer (ear, digital, rectall or pacifier) and put the digital underneath your tongue and wait till it beeps. the same with the rest but the ear thermometer in the ear and rectall thermometer in the rectall. Hope you get better soon xox <3
Which is more better to use a glass thermometer or a plastic thermometer?
There is no difference in the effectiveness of glass or plastic. Glass is more fragile for breaking but easier to keep clean, plastic is safer for not breaking, and harder to keep clean longer. It is a personal choice.
What does cimecels mean?
Cimecels has something to do with Mercury being better then Alcohol on a thermometer.
Are alcohol thermometers better than mercury thermometers?
Both alcohol and mercury thermometers are effective for measuring temperature, but alcohol thermometers are generally safer to use due to the toxicity of mercury. However, mercury thermometers provide more accurate readings at higher temperatures compared to alcohol thermometers.
Would ethanol be better than mercury for an outdoor thermometer in the arctic?
Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.
Which is better mercury or alcohol thermometers for low temperature measurements?
Alcohol thermometers are generally better for low temperature measurements as they have a wider temperature range, reaching lower temperatures than mercury thermometers. Additionally, alcohol is less toxic than mercury, making it safer to use in certain applications.
Compare the expansion of mercury with alcohol?
Mercury expands more evenly than alcohol. This is why thermometers that contain mercury are more accurate than those that contain alcohol. However, alcohol freezes at a temperature much lower than mercury, so it is better used in thermometers in extreme cold conditions.
Which liquid would be better in the thermometer. why?
Mercury is commonly used in thermometers due to its high thermal conductivity and visibility in the narrow tube, allowing for accurate temperature readings. Alcohol thermometers, on the other hand, are safer and less toxic compared to mercury thermometers. The choice of liquid depends on the specific use and safety considerations.
Why is digital thermometer is better than mercury thermometer?
Digital thermometers are preferred over mercury thermometers because they are more accurate, faster, and safer to use. Digital thermometers provide a digital reading, eliminating the risk of parallax error associated with reading a mercury level. Additionally, digital thermometers do not contain mercury, making them safer for the environment and in case of accidental breakage.
Does mercury in a thermometer go bad?
No. But glassware is not a crystalline rigid material, and has some memory of recent thermal movement. Thermometers that have been calibrated at manufacture, will have a couple of tiny scratch marks along the scale, and the graduations in between are interpolated. If you wish to calibrate a thermometer, then do so at the triple point (close to 0 deg C), and at boiling point - 100 degree C. Since much of the stem of the thermometer has been at 100 degree C, straightaway after removing from the steam, the glass tube will shrink, and the reading will change due to this, as well as the mercury column cooling. For a thermometer to be a precision measuring device, the bore has to be accurately true, and this is not always the case. Ordinary mercury thermometers are seldom to be relied upon for better than 1 degree C resolution.
Mercury or ethanol thermometer in arctic?
An ethanol thermometer would be better suited for use in the arctic compared to a mercury thermometer. This is because ethanol has a lower freezing point (-114°C) compared to mercury (-39°C), making it more reliable in extremely cold temperatures. Additionally, ethanol is safer to use as it is non-toxic in case of breakage.
Can frozen alcohol catch on fire?
I'm not sure but freezing it is the problem you better have a freezer that can go 200 degrees below 0.
What dangerous liquid used in thermometers?
Mercury would be the dangerous liquid used in thermometers. Many modern thermometers are made without mercury for safety reasons, but if a thermometer breaks and you're not sure, it's better to be careful with the cleanup.
Why clinical thermometer is jerked before using it again?
If you have an old thermometer that has mercury, then the shaking makes all of the mercury flow to the bottom of the thermometer. Then, you can get a better reading. The current digital ones work differently. Thermometers used for taking people temperatures are a special kind that go up with heat but don't go down with cold. So you have to shake a thermometer before taking your temperature to make the reading go down below your own temperature. Then the thermometer can go up again to read your temperature.
