Measuring mass with an electronic balance:

-

The electronic balance has many advantages over other types of balance. The most obvious is the ease with which a measurement is obtained. All that is needed is to place an object on the balance pan and the measurement can be read on the display to hundredths of a gram. an electronic balance A second advantage, using the Zero button on the front of the balance, is less recognized by beginning science students. Because one must never place a chemical directly on the balance pan, some container must be used. Place the container on the balance and the mass of the container will be displayed. By pressing the Zero button at this point, the balance will reset to zero and ignore the mass of the container. You may now place the substance to be weighed into the container and the balance will show only the mass of the substance. This saves calculation time and effort. However, when the container is removed from the balance, the display will go into negative numbers until the Zero button is pressed again.

Our electronic balances also have a Unit button on the front. Pressing this button will change the units being measured. Since we have very few times when we need something other than metric units, you should not have to change the mode on the balance. Because of the Unit and Zero buttons, there are two things you must always do before placing objects onto an electric balance to be measured:

1. See that the display is reading 0.00
2. See that the unit sign in the upper right of the display shows g

When finished with the electronic balance, press the On/Off button and hold it down until the display shows OFF.

0.1 M TEA: TEA = Triethanolamine You will dilute TEA 1:10 in Millipore water: Pour 50 mL TEA into a 50 mL conical tube (TEA is very viscuous, so best to measure it in something that is disposable). Pour TEA from conical tube into 450 mL Millipore water with stirring. pH to 8.0

It is a known fact for anyone working in a laboratory be it the students, the researchers, scientists or lab assistants, it is necessary to follow safety rules and guidelines for their own safety. All laboratories have their lab safety symbols and lab safety equipments like goggles, mask, dress etc. At the same time, it is also very essential that a laboratory is well-maintained and taken care of so as to prevent any kind of dangers involved while working in a lab. As per rule, there should be routine maintenance and safety checks in a laboratory. Infact, it should be the duty of every person working in a laboratory to do a quick safety check after the completion of each experiment and before the starting of a new one. Or a responsible personnel should be assigned the duty to clean the laboratory and perform simple maintenance for lab care and safety . Laboratory Maintenance Presenting below few points which should be considered for laboratory maintenance: Bench:
