Reagent bottles can be used for the storage and transportation of special chemicals, diagnostic reagents, biological products, reagents, adhesives and veterinary drugs. At present, reagent bottles are mostly made of glass and plastic, but glass is fragile and cleaning is cumbersome. Therefore, plastic reagent bottles with strong mechanical properties and resistance to acid and alkali corrosion have gradually become a common choice in the market. High-density polyethylene (HDPE) and polypropylene (PP) are two commonly used plastic materials. So how should you choose reagent bottles made of these two materials?
1. Look at the tolerance temperature
HDPE material is resistant to low temperature but not high temperature. Therefore, when low temperature storage is required, reagent bottles made of HDPE are more often chosen. PP material is resistant to high temperature but not low temperature. When high temperature and high pressure sterilization is required, reagent bottles made of PP material are chosen.
2. Look at chemical resistance
Both HDPE material and PP material are acid and alkali resistant, but HDPE material is better than PP material in terms of oxidation resistance. Therefore, when storing oxidizing reagents, such as benzene rings, n-hexane, chlorinated hydrocarbons and other organic solvents, HDPE materials should be selected.
3. Look at the sterilization method
In terms of sterilization methods, the difference between HDPE material and PP material is that PP can be sterilized under high temperature and high pressure, but HDPE cannot. Both HDPE material and PP material can be sterilized by EO, radiation sterilization (irradiation-resistant PP is required, otherwise it will turn yellow) and disinfectant sterilization.
4. Look at the color and transparency
The color of reagent bottles is generally natural (translucent) or brown. Brown bottles have excellent light-shielding effect and can be used to store chemical reagents that are easily decomposed by light, such as nitric acid, silver nitrate, silver hydroxide, chlorine, etc. Natural bottles are used to store general chemical reagents. Due to the influence of molecular structure, PP material is more transparent than HDPE material, making it easier to observe the status of the materials stored in the bottle.
Whether it is a reagent bottle made of PP or HDPE, there are types of chemical reagents suitable for holding according to its material characteristics. Therefore, the characteristics of the chemical reagent should be taken into consideration when selecting a reagent bottle.
Aijin biological reagent bottle
1. Product material
High-quality high-density polyethylene (HDPE) and imported medical-grade polypropylene (PP) are available, which are resistant to moisture and pressure.
2. Product color
Available in natural color (translucent) and brown. The brown reagent bottle has excellent light-shielding effect and can be used to store light-sensitive substances; the natural color reagent bottle facilitates observation of the internal liquid state.
3. Bottle mouth design
Wide mouth/narrow mouth design, can store solid and liquid. The wide mouth of the wide-mouth bottle can be used to store solid reagents; the narrow-mouth bottle is mainly used to store liquid reagents, effectively reducing reagent volatilization.
4. Leak-proof design
Unlined lid allows for better sealing and enhanced leak protection.
5. Complete specifications
There are 8/15/30/60/125/250/500/1000 mL reagent bottles to choose from, which can meet the holding needs of most reagents.
