Plastic bottles

Introduction to Plastic bottles

Laboratory plastic bottles are specialized containment vessels used for storing, preserving, and transporting chemicals, solvents, and liquid or solid samples. This product line helps laboratories minimize the risk of breakage during handling while ensuring operator safety when working with corrosive solutions.

When choosing plastic bottles, users should consider the chemical compatibility of materials such as PE, PP, PFA, or PET. The PFA bottle line is suitable for trace analysis solvents and strong oxidizing agents; PP bottles withstand autoclaving at 121 °C (2 bar) according to DIN EN 285; while amber PE bottles are specialized for protecting light-sensitive substances. Depending on sample characteristics, laboratories can choose narrow-mouth, wide-mouth, or VITgrip designs with capacities of 50ml, 125ml, 250ml, and 500ml from brands such as Aptaca (Italy) and Vitlab (Germany).

When should PFA plastic bottles be used instead of PE or PP?

PFA bottles are made from fluorinated polymers and are particularly suitable for the long-term storage of high-purity oxidizers, acids, bases, hydrocarbons, and solvents in trace analysis. For general chemicals or routine sample storage applications, PE or PP plastic bottles are more cost-effective alternatives.

Can laboratory plastic bottles be autoclaved?

Only plastic bottles made from polypropylene (PP) are autoclavable at 121 °C and 2 bar pressure in accordance with DIN EN 285 standards. When autoclaving, operators must loosen the bottle cap to prevent deformation caused by pressure differentials.

Which brands of plastic bottles does Hoa Viet supply?

Hoa Viet currently supplies laboratory plastic bottle lines from two manufacturers: Aptaca (Italy) and Vitlab (Germany). Customers can contact Hoa Viet for detailed technical advice and to request a quote.

Should I choose wide-mouth or narrow-mouth plastic bottles?

Narrow-mouth plastic bottles are suitable for storing and pouring liquids, helping to minimize the risk of spills or evaporation. Conversely, wide-mouth plastic bottles are more convenient for loading and retrieving powdered, granular, or viscous samples, or for cleaning the inside of the bottle.
