Premium Lab Glass Cylinder Set of 4-5ml 10ml 50ml 100ml Laboratory Glassware with Cleaning Cloth and Brush Set

One of the glass cylinders in the first set i received had arrived broken, in half, and another was chipped. The supplier replaced it quickly and the second set is perfect. The quality of the glass is comparable to what i use in a research lab

Fantastic durability and exact measurement markings. The box the units are shipped in has a foam inside and is perfect for storage while these are not in use.

Seem alright. Measured up against other graduated cylinders i have and seem to be accurate to me. First order came with 2 of the cylinders chipped on the base. Contacted seller about repacibg tye 1, they said theyd just send a whole new kit, and they did. But unfortunatly the same large cylinder also had a chip on its base. Doesnt realy effect the item, just carefull on cutting your fingers.

Les deux petits cylindres de 5 et 10 ml ont l'arrête de leur base tranchante et un peu ébréchée et on doit jouer du papier sablé pour les rendre plus lisses. Les deux grands sont OK.

Not very accurate. If you need something that is accurate, this isn't the product!!
