The Selection of Plastic Laboratory Bottles

The Selection of Plastic Laboratory Bottles

Jul 7,2022

People who work in the laboratory know that there are many large and small bottles used to hold a variety of solvent liquids, granular powders, etc. And these solvents, liquids, granular powders will be more or less corrosive or special chemical properties, in contact with certain materials will occur when the chemical reaction. So these solvent liquids, granular powders are extraordinarily strict requirements. The most basic of these requirements is from the bottle!

Plastic laboratory bottles in a wide range of shapes and sizes, also plays a important role in wash, sampling, or storage different chemical in various types of laboratories.  Let's see what is a plastic lab bottle used for in a lab as below.

1.  Reagent Bottles

Plastic reagent bottle is a kind of packaging container commonly used for various chemical reagents, which has the characteristics of good resistance, non-toxic, light quality and unbreakable. Its production raw materials are mainly polypropylene.

According to the size of bottle mouth, it is divided into  wide mouth bottle  and narrow mouth bottle.  Wide mouth reagent bottle is used for holding solid reagents and narrow mouth reagent bottles is usedfor holding liquid reagents. 

The interior of the bottle mouth is frosted to keep the seal and prevent the reagents from leaking out. There are also transparent and brown bottles, and brown bottles are used to hold reagents that need to be kept away from light.

Compare with glass reagent bottles, plastic reagent bottles are not easy to be broken during the transportation and use.

2.Wash Bottles

In the chemical, chemical, biological, pharmaceutical, food, geological, metallurgical, environmental and other industries, institutions, enterprises, scientific research institutions, laboratories, are used to rinse the experimental vessels and solution preparation and filling distilled water wash bottles.

The wash bottles are often composed of a plastic bottle with a thin mouth and a water pipe at the mouth of the bottle, some of which are integrated with the lid, and some of which are extended through the lid into the bottle.

Different types of wash bottles: Economic wash bottle (commonly used 500ml economic wash bottle), safety wash bottle (distilled water wash bottle, toluene wash bottle, ethanol wash bottle, methanol wash bottle, acetone wash bottle, isopropyl alcohol wash bottle, sodium hypochlorite wash bottle), solvent resistant wash bottle, plastic wash bottle (red) (i.e. red mouth wash bottle).

2.Dropper Bottles
dropper bottles

Dropper bottle with controlled dispensing tip for repeatable and accurate dispensing of reagents. The dropper bottle is an excellent alternative to pipetting devices, one drop at a time, with each drop based on water data; viscosity affects droplet size. 

Made of LDPE material make the dropper bottle has excellent chemical resistance and is suitable for most biotech, diagnostic and pharmaceutical applications.
