Rules for taking liquid reagents in reagent bottles
Chemical reagents are divided into solid, liquid, powder, granule and other different types according to the difference in form. Different reagents need to choose reagent bottles that meet their characteristics, so the reagents will be different when they are used.[ 1000ml Glass Reagent Bottle,Wide Mouth Reagent Bottles,Chemical Reagent Glass Bottles,Chemical Reagent Bottle,Wide Mouth Transparent Reagent Bottle ]
In order to prevent the reagents from spilling out and avoid the reagents from volatilizing, liquid reagents are mainly stored in narrow-necked bottles with smaller mouths, and the following rules should be followed when taking them:[ 1000ml Glass Reagent Bottle,Wide Mouth Reagent Bottles,Chemical Reagent Glass Bottles,Chemical Reagent Bottle,Wide Mouth Transparent Reagent Bottle ]
1. When using a small amount of liquid reagents, usually use a glue-tip dropper to draw, and use the pouring method when the amount is large.
2. When pouring the liquid from the narrow-necked bottle into the container, hold the label side of the reagent bottle in the palm of your hand, hold the container obliquely with the other hand, and make the mouth of the bottle contact with the mouth of the container, gradually tilt the reagent bottle, and pour Out the reagents.
3. The reagent should flow into the container along the container wall, or guide the liquid reagent into the narrow-mouthed or flat-bottomed container along the clean glass rod.
4. After taking out the required amount, gradually erect the reagent bottle and bump the remaining droplets from the bottle mouth into the container to prevent the droplets from flowing down the outer wall of the reagent bottle.
5. If there is no prescribed dose in the experiment, generally take 1 to 2 mL. For quantitative use, you can choose a meter, a burette or a pipette according to your requirements.
6. If you take too much reagent, you can’t pour it back into the original reagent bottle, let alone discard it at will. You can pour it into a designated container for others to use. Especially when taking toxic reagents, it should be taken in strict accordance with the rules.
Chemical reagents are often dangerous, such as flammable, explosive, volatile, highly toxic, perishable, easy to oxidize, etc. You need to pay special attention when taking reagents. Knowing the characteristics of various reagents and the rules of use can ensure the experiment Safety to avoid dangerous accidents.[ 1000ml Glass Reagent Bottle,Wide Mouth Reagent Bottles,Chemical Reagent Glass Bottles,Chemical Reagent Bottle,Wide Mouth Transparent Reagent Bottle ]
