Mercury is no longer used much in thermometers due to the poisonous compounds that it forms.

When I grew up, in Chemistry at school and at the doctors there were mercury thermometers and alcohol thermometers.

The difference between a clinical and mercury thermometer?

All righto, ya gotta 'no wat da clinic n' da mercury thermometer is da... Foistly, clinic thermometer is da thermometer used to measure body temperature. Often the liquid inside it is mercury, but sometimes it is alcohol. It is very accurate because it has a narrow place where the liquid rises very fast. Den da mercury thermometer consists of mercury. Basically, it has..... yea blah blah blah, just look it up in ya dictionary. Anyways, da thing is there must be a problem with da questieon. Mercury thermometer has a almost accurate point but clinical thermometers have a very accurate things becausse it has a narrow place where the liquid rises very fast.


Who invented laboratory thermometers?

There is debate on who invented the first laboratory thermometer especially since there different kinds invented at different times. However, many think the credit should go to Italian professor, doctor, and physiologist Sanctorius for the air thermometer in 1612.


What is the coloured substance used in thermometer?

The colored substance commonly used in a thermometer is typically either dyed alcohol or a non-toxic organic liquid like mercury. These substances expand and contract with changes in temperature, allowing the thermometer to measure temperature variations.


What are the two substances used in a liquid column thermometer?

The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.


What is difference between a clinical and a laboratory thermometer?

A lab thermometer normally is very long and has a wide range of measurement with uniform degrees spread out over the distance and has a mark showing how far into the measured substance it go to get accurate measurements.A clinical thermometer has a larger bore at the bottom where the contents can expand without measurement occuring then a tiny bore where the degrees are spread out at the body temperature. Thus at room temp, all the liquid is down in the big area and only as it gets up to 95 degree or so is the liquid expanded in the reading area. This allows the thermometer to be physically short and easy to handle while having wide degrees to be easy to read. There is also a trap so that the column separates leaving liquid in the tiny bore to read instead of dropping quickly on removal. The liquid has to shaken out of the tiny bore back into the big one.

Which metal is used in clinical thermometer?

Mercury is used in clinical thermometers.


What is the mercury called on a clinical thermometer?

The liquid in a clinical thermometer is called mercury. It is used to measure body temperature by expanding and rising within the thermometer.


What is the difference between clinical thermometer and laboratory thermometer?

Laboratory thermometers can measure wide variety of temperature, whereas a clinical thermometer has a range between 95 to 105 Fahrenheit. Clinical thermometers are made to be used in a hospital to accurately determinebody temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park". Clinical thermometer may have mercury but lab thermometers usually have alcohol .

Difference between laboratory and clinical thermometer?

A laboratory thermometer is used to measure temperature with high precision in controlled environments, such as in research labs. Clinical thermometers are designed to measure body temperature for medical purposes, typically with less precision but greater convenience for home use.

Difference between clinical and a laboratory thermometer?

A clinical thermometer can only measure human body temperatures since it can measure no less than 35 degrees celcius and no more than 42 degrees celcius. An ordinary thermometer can measure and object or substance at any temperature.

Why care must be taken when disposing of a mercury-in-glass thermometer?

Well i'm not that old but i know a few:1)The thermometer will be of two types; a) Clinical Thermometer b) Laboratory Thermometer;a) The Clinical Thermometer: used to measure the temperature of the human body, at home, clinics and hospitals.b) The Laboratory Thermometer: used to measure the temperature in school and other laboratories for scientific research.Precautions:Wash the thermometer before and after use with an antiseptic solution, and handle it with care.See that the mercury levels are below the kink and don't hold the thermometer near its bulb.While noting down the reading in the thermometer, place the mercury level along the eye sight.Do not place the Clinical thermometer in a hot flame or in the hot sun.Note:The Clinical Thermometer should go above 108*F (42*C) and below 94*F (35*C) otherwise it might blow off the top and leak. Therefore, a Clinical Thermometer is used to measure the body temperature.


Is alcohol used for clinical thermometers or laboratory thermometers?
