Setting glassware

 heavier equipment on the bottom and the lighter in the higher

 tool size is higher in the back and a low or short in front

 tool length lying position / lie down

 tools that do not have a backrest (round-bottom flask) are stored in

(20)

Setting glassware

•

All equipment is inventoried in the

book inventory records

•

Each device is placed in

accordance with the kind of tools

and size

•

Use of the tool should be

recorded in the log book out tools

•

All the tools were kept back

(21)

Settings tool instrument

 In a special room with specific requirements

For example: GC, UV-VIS and FTIR have AC

 Placed electrodes

immersed in the solution

 The use by people who are experts, appropriate manual tool

M aintenance of Balance

f not reached equilibrium there are 2 ways:

Small-scale shear load at the front to the right until it reaches equilibrium and mark shows what number of small loads that have shifted it. When used for weighing, then the value / number is later as a deduction. The mass of the load that weighed less number / scale of small loads that have shifted it.

Remove the mounting plate portion hanging weights, and go to the bottom using a screwdriver and

complete or subtract expenses (such as buckshot, nails, small metal / powder).

Balance is often

damaged due to these factors:

a. Failure to use b. storage

c. The process of
