Glass Beaker 25ml - 1000ml Borosilicate Glass Measuring Cup Low-Type Beaker with Graduation & Spout Chemistry Lab Glassware(1000ml 1pcs)

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.How to use the beaker and matters needing attention: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. Do not heat the beaker directly with flame.Because the bottom surface of the beaker is large, it can only be burned to a local area if it is heated directly by flame, which will cause the glass to be heated unevenly and cause explosion. The outer wall of the beaker must be wiped dry during heating.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.6. When heating corrosive drugs, a watch glass can be placed on the mouth of the beaker to prevent the liquid from spilling.7. Do not use a beaker to measure liquid.==========Model Number : 25ml - 1000mlOrigin : Mainland ChinaClassification : BeakerMaterial : BorosilicateCapacity : 25 - 1000 mlPacka
