Do you need graduated cylinder at medical school?

Your tuition should cover lab ware.  I do not think you will need to buy lab ware such as graduated cylinders, flasks, beakers, funnels, volumetric pipettes, etc.

Besides, most schools get their lab ware from a specific supplier, like Fisher Scientific or VWR Scientific, and because they order a lot of the supplies, they get them at a cheaper price, therefore it is better for them to buy them and not each student buy them on their own.

Also of course you have your Class A and Class B type lab ware, but even besides that, some schools prefer that all students use the same brand (even though all Class A are supposed to meet the same standards) some people feel that Pyrex brand is better than VWR brand or Fisherbrand, etc.)

It would be very unlikely that you would need your own graduated cylinder or any other equipment like that to start medical school. Labs will have equipment you need and things like drugs are either pre-prepared or measured using sterile syringes.
If you have your heart set on one or have the oppurtunity to steal one I say go for it though!!

Most likely Lab will be equipped. So no need to buy or carry cylinder, pipette, beaker etc.
You can ask your school if they want you to buy it. Unless you might just spent some money unnecessarily.
