5pcs High Temperature Corrosion-Resistant Glass Stirring Rod, Glass Rod, Drainage Rod, Guide Rod, Diameter 5-8mm, Length 15-40cm for Laboratory Supplies and consumables. (D7mm,L15cm)

High borosilicate glass stirring rod Product use: For chemical experiments, it is a glass rod shaped simple stirrer, also known as a glass rod, used to accelerate stirring and solute dissolution, promote mutual solubility, drain water during filtration, dip in liquid, stir in an evaporating dish to prevent splashing caused by uneven heating, and can also be used to evaporate and crystallize a small amount of solution. Especially in middle school experiments, it is the most commonly used and essential experimental equipment. Product features: Lead free environmentally friendly glass, with a softening temperature of up to 820 ℃, inherits the appearance quality of lead containing crystal glass without containing lead. Can withstand drastic temperature changes of 200 ℃. Fine craftsmanship, high transparency, and smoothness. The material is stable and highly corrosion-resistant. Glass is formed by melting silicon dioxide and other chemical substances together, and its properties are stable and corrosion-resistant.
