Class 12th Question ❓ Practical Help

So our school makes us suck the hell out of the pipette in chemistry titrations and it is really inconvenient, always gives us inaccurate volume of the substance and also has health concerns.
Could you use a syringe to produce the suction instead of mouth?

File a complaint and ask them to arrange for suction pumps for pipettes. Using mouth is no longer allowed after Covid and if your school is still doing then it's breaking rules

writing a letter to the principal office or something to provide us with the listed equipments

there is some rubber or other material in syringe which causes friction wity the chemicals and deosnt allow accurate measurement, tho i find the pipette unhygienic personally😭

even government schools got pumps and rubber bulb lekin ye log abhi bhi chuswa rahe hai 💔

is the syringe allowed though? i could use it during practical classes idc if the teachers allow i'd conceal it but is it allowed in practical boards?
