Glass Beaker 玻璃量杯 (5ml, 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml)

Designed with excellent mechanical strength, an extra large marking spot, a convenient pour spout, and high-quality borosilicate glass, these beakers can be heated directly in an open flame.

Unlike plastic beakers, these more heavy-duty glass beakers can be used for mixing and gentle heating, and has thermal shock resistance - meaning it will withstand typical laboratory thermal variations common to chemistry processes (like heating and cooling). 

Material: Glass

Volumes: 5ml, 10ml, 25ml, 50ml, 100ml, 250ml, 500ml, 1000ml

這些燒杯的設計具有出色的機械強度、超大的標記點、方便的倒水口和高質量的硼矽玻璃，可以直接在明火中加熱。

與塑料燒杯不同，這些更重的玻璃燒杯可用於混合和溫和加熱，並具有抗熱震性--意味著它能承受化學過程中常見的典型實驗室熱變化（如加熱和冷卻）。
