This beaker is made with Borosilicate glass (Boro3.3) which is a type of glass that contains boron trioxide which allows for a very low coefficient of thermal expansion. This means it will not crack under extreme temperature changes like regular glass. It is highly resistant to concentrated acids and acid mixtures, and to chorine, bromine, iodine and organic substances.

We have below size variants.
​​​​​​​size : 50ml = 60.9mm (height) x 51.9mm (width)
size : 100ml = 74.4mm (height) x 63.7mm (width)
size : 150ml = 86.3mm (height) x 72mm (width)
size : 250ml = 98.2mm (height) x 84.1mm (width)
size : 500ml = 125.9mm (height) x 102.9mm (width)

主要材料 Materials: Borosilicate glass Boro3.3

用法 Instruction: Follow the lowest point at the surface of the liquid to the wall of the graduated cylinder. Read the volumetric scale at this point. If you have trouble seeing the meniscus, try holding a black card against the opposite side of the graduated cylinder at the same height as the liquid.

注意事項 Contraindications: 在加熱液體前,應確保燒杯外壁是乾燥的,以防燒杯受熱不均勻。在加熱液體時,液體的體積不能超過燒杯容積的三分之一,以防液體沸騰而濺出。用明火進行加熱時,應該隔著石棉網加熱,使得燒杯底受熱均勻。
