Usually, the ____________ which is designed for lab glassware is used. You can ____________ the glassware with the proper ____________, then finish up with a couple of rinses with distilled water, followed by final rinses with deionised water. Remove ____________ and stopcocks when they are not in use. Otherwise they may ‘freeze’ in place. Wear ___________ and avoid breathing the ____________. If the glassware requires scrubbing, scrub with a ___________ using hot soapy water, rinse thoroughly with ____________, followed by rinses with deionised water. In some cases, you may need to __________ the glassware overnight in soapy water. It is inadvisable to dry glassware with a ___________ or forced air since this can introduce fibres or __________ that can contaminate the solution. Normally you can allow glassware to air dry on the shelf. Otherwise, if you are adding water to the glassware, it is fine to leave it wet (unless it will affect the concentration of the final __________). If the solvent will be ether, you can rinse the glassware with ethanol or acetone to remove the water, and then rinse with the final solution to remove the alcohol or acetone. If ____________ is to be used immediately after washing and must be dry, rinse it 2-3 times with acetone. This will remove any water and will ____________ quickly.
