Glass Beaker 25ml - 1000ml Borosilicate Glass Measuring Cup Low-Type Beaker with Graduation Spout Chemistry Lab Glassware(Size:25ml 4pcs)

Material: BorosilicateCapaicty: 25 ml - 1000 mlPackage: 25ml and 50ml package as 4/PK, 100ml - 400ml package as 2/PK, 500ml - 1000 ml package as 1 /PK.Low-type beaker is used as a reaction vessel for preparing solution dissolved substances and larger quantities under normal temperature or heating conditions.This beaker is made of high borosilicate glass. The borosilicate hydrochloric acid glass has a high coefficient of thermal expansion, high temperature resistance, and resistance to sudden changes in temperature of 200.Model Number : 25ml - 1000mlClassification : BeakerMaterial : BorosilicateCapacity : 25 - 1000 mlPackage : 10/PK, 8/PK, 6/PK

• 1. Common specifications are 50mL, 100mL, 250mL, etc., but no beaker is required to measure liquid.
• 2. When heating the beaker, it should be covered with asbestos net to make it evenly heated.
• 3. When used for dissolution, the amount of liquid should not exceed 1/3 of the volume of the beaker.And use a glass rod to keep stirring gently, do not touch the bottom or wall of the cup when the glass rod is used for stirring during the dissolution or dilution process.
• 4. When heating the liquid, do not exceed 2/3 of the volume of the beaker, generally 1/2 of the volume of the beaker is appropriate.
• 5. During the dissolution or dilution process, do not touch the bottom or wall of the cup when stirring with a glass rod.
