No, you do not need to empty the boric acid from a urine sample bottle before use. The boric acid acts as a preservative to keep the sample stable until it can be tested.

Microbiologists use autoclaves to sterilize equipment, laminar flow hoods to create a clean work area, incubators to provide optimal growth conditions, and pipettes to transfer samples without introducing contaminants. They also use culture media that has been sterilized before use.
the thermometer is shaken before it is used because it is
A suspension is a mixture of two or more substances, where one is finely divided and distributed in another. The particles are usually larger than those in a solution and may settle over time due to gravity. Examples of suspensions include muddy water and certain medicines that need to be shaken before use.
Suspensions, emulsions, and certain oral solutions that contain particles or components that settle should have a "shake well" label. This label indicates that the product needs to be mixed thoroughly before each use to ensure proper dosing.

The liquid form should be refrigerated and shaken well before use. All other forms can be kept in a tightly sealed container at room temperature and protected from heat or light.
Well, it depends on what it is. Is it a prescription medication? If it is something like amoxicillin (Amoxil), azithromycin (Zithromax), cefdinir (Omnicef), etc. then yes. Those are suspensions so you always want to shake those well before each use. There is no need to shake a gel because it doesn't settle. Generally, colloids shouldn't need to be shaken. Milk is an example of a colloid. Solutions can be shaken every once in a while but it won't hurt if you don't shake them. -Syrich Nationally Certified Pharmacy Technician
Well, a clinical thermometer is shook after use so that the mercury comes back to its initial point i.e. where it had been before the temperature was taken.

If the clinical thermometer is a mercury based thermometer, it needs to be shaken down prior to each use. This is because there is a pinch point between the mercury reservoir bulb and the capillary tube, to ensure that the mercury does not shrink back into the bulb after the temperature has been taken. The mercury has therefore to be shaken back into the bulb before another measurement can be made. One should note that in many countries use of mercury based clinical thermometers is now discouraged (because mercury is toxic) and electronic thermometers are used in stead - these do not need shaking.
no its not ...its a separation and ther for has to be shaken before use then it becomes a temparary colloid ...source >>ive studyed it
