Two major classifications of packaging

There are two main types of plastic packaging, namely stretch wrapped plastic packaging and various bags. Stretch wrapped plastic packaging is composed of plastic film that has not yet formed a plastic packaging shape. It is simply wrapped around one or more products to be plastic packaged and fixed in place in some form. Plastic bags are made into a certain shape before or at the same time as the product is loaded. A common method is to heat seal the plastic edge to form this shape.

Requirements for the use of reagent bottles in chemical reagents

HF solution cannot be stored in glass bottles due to corrosion of glass. Plastic bottles or lead containers can be used instead. Other reagents are generally stored in glass bottles. General solid reagents are stored in wide mouth bottles, while general liquid reagents are stored in fine mouth bottles. Reagent bottles containing alkaline substances (such as NaOH, Na2CO3, Na2S, etc.) or water glass must be stoppered with rubber or cork. Because alkaline substances or water glass can react with silica in the glass, resulting in the adhesion between the bottle and the stopper. It is advisable to use glass stoppers without special instructions. Reagents that are easy to decompose when exposed to light should be stored in brown wide mouth bottles or thin mouth bottles. For example, AgNO3, chlorine water, hydrogen peroxide, bromine water, and unstable organic compounds are generally stored in colorless reagent bottles. Drip bottles cannot store liquid reagents that are prone to evaporation, volatilization, and have a corrosive effect on the adhesive head. Dropping bottles are generally not used as long-term storage reagents. Reagents that are easily decomposed by light should be stored in brown bottles.

Precautions for using droppers

When adding, the dropper should be kept perpendicular to the top of the container, avoiding tilting, never upside down, and should not extend into the interior of the container or touch the container wall. Except for absorbing the solution, the tip of the tube should not come into contact with other objects to avoid contamination by impurities. It cannot be used in two ways. The ordinary dropper needs to be cleaned after use, while the specialized dropper cannot be cleaned. It needs to be used exclusively and can be replaced with the original reagent bottle after use.
