1、Round (flat) bottom Boiling flask
●Specification: Capacity (mL) 5-2000, can be matched Rubber stopper
●Main use: heating and distilling liquid, flat-bottomed flask can be equipped Washing liquid
● Note: Generally avoid direct heating on the fire, should be stone Cotton net or various heating sleeves, heating bath heating, etc.,
●The contents are not More than 2/3 of the volume
●Specifications: Capacity (mL) 10-1000
●Main use: heat treatment sample and capacity analysis titration
●Notes
1) It should be placed on the asbestos net when heated to make it evenly heated.
Do not dry, do not exceed the total volume of the solution when heated 2/3 of the product
2) Open the stopper when grinding the triangular flask, non-standard grinding Mouth bottle to keep the original plug
3、Washing bottle
●Specifications: capacity (mL) 250, 500,
●Main use: packed with pure water
● Note: mostly plastic products, can not be loaded with hot solution
4、Separating funnel
●Specifications: Capacity (mL) 30-5000
●Main use: Separate two mutually incompatible liquids for extraction Separation and enrichment;
● Note: the grinding cock must be the original, the leaking funnel is not Can be used, not heated, apply Vaseline on the piston, make it turn Flexible, tight and tight; when not in use for a long time, a strip of paper is required at the grinding point
5、Condenser
●Specifications: straight, spherical, serpentine, air condensing tube
●Main use: used to cool distilled liquid, suitable for serpentine tube For condensing low-boiling liquid vapor, air condensing tube for cold Liquid vapor with a boiling point above 150 °C
● Note: Do not quench and heat up, pay attention to the cold water Cold water out of the mouth; slowly open the cooling water, the water flow should not be too large
