Clean beakers, volumetric bottles, conical bottles, etc with different ways
labware beaker,heat resistant beaker,laboratory glass beaker,2000 ml beaker
General glass instruments, such as beakers, flutes, cone-shaped bottles, test tubes and measuring cylinders, are washed with a brush from the outside to the inside with water, so that water soluble substances can be washed off, part of the insoluble substances and dust;labware beaker,heat resistant beaker,laboratory glass beaker,2000 ml beaker If there is oil pollution and other organic matter, with detergent powder, soap powder or detergent for washing. labware beaker,heat resistant beaker,laboratory glass beaker,2000 ml beaker Scrub with a brush dipped in detergent or detergent, and then rinse clean with runn ing water, and then rinse the inner wall with distilled water or deionized water 2 to 3 times. labware beaker,heat resistant beaker,laboratory glass beaker,2000 ml beaker The inner wall of the cleaned glass instrument should be able to be evenly wet by water without water stripes, and do not hang water droplets. In organic experiments, often use grinding glass instruments, cleaning should pay attention to the protection of grinding mouth, not the use of detergent, instead of detergent.
For not easy to brush with brush or brush with brush not clean glass instruments, such as burette, volumetric bottle, pipette, usually pour detergent or suction into the container after soaking for a period of time, the container of detergent into the storage bottle for reserve, and then rinse with running water and deionized water.
Sand core glass filter immediately after use must be clean, according to the residual filter cores of different sediment, using the appropriate surface precipitation of the solid detergent to dissolve cores, then by decompression smoke wash a method to use detergent to repeatedly sediment cores in the residual all smoke wash, then rinse clean with distilled water, in the 110 ℃ drying, stored in the cabinet of the dust.
