Polypropylene Reagent Bottle

What is the Polypropylene Reagent Bottle?

A polypropylene reagent bottle stores aqueous and many solvent reagents with a leak-resistant screw cap. It is light, unbreakable and resistant to acids and bases, with a leak-resistant screw cap and PTFE-faced liner.

Overview

The bottle is moulded in polypropylene with a screw cap, usually with a polypropylene or PTFE-faced liner, and is available in 30 mL to 5000 mL sizes. It resists most acids, bases and alcohols, tolerates autoclaving and is suitable for shipping because it does not break. The cap forms a strong seal but is not a barrier to solvent vapour over long periods, so volatile solvents may be lost and odour emitted; glass with a PTFE-lined cap is better for long-term solvent storage. Polypropylene can adsorb hydrophobic compounds, so it is avoided for trace organic standards but is preferred for inorganic solutions and for alkalis that attack glass. Graduations are approximate, and the translucent material limits meniscus reading.

How does it work?

Plasticware works because polymers can be moulded into precise, low-cost shapes and selected for specific properties. Polypropylene resists most acids, bases and solvents, tolerates autoclaving and is translucent but not optically clear, so it is used for beakers, bottles and carboys. Polycarbonate is clear and tough, so it is used for centrifuge bottles where the contents must be seen and the vessel must resist high g forces. Polystyrene is optically clear and rigid, which suits cell culture flasks and dishes, and is supplied sterile and sometimes treated for cell attachment. Polyethylene is flexible and used for wash bottles and tubing. Unlike glass, plastics can adsorb analytes, leach additives such as plasticisers, and scratch, so they are chosen for applications where inertness requirements are lower or where disposability reduces contamination risk.

What are the key features?

• Moulded polypropylene with screw cap
• Capacities 30–5000 mL
• Resists acids, bases and alcohols
• Unbreakable for shipping
• Autoclavable at 121 °C
• PP or PTFE-faced liner

What are the technical specifications?

A typical polypropylene reagent bottle configuration offers material of Polypropylene, capacity range of 30–5000 mL, closure of Screw cap, liner of PP or PTFE-faced, max temperature of 121 °C autoclave and chemical resistance of Acids, bases, alcohols. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Polypropylene Reagent Bottle is used in alkali storage, inorganic reagent storage, sample shipping and general bench storage. Across the wider Plasticware class, laboratories also deploy it for reagent and buffer storage, cell culture and microbiology and centrifugation.

Which standards and certifications apply?

Relevant standards and methods include USP <661> (plastic components and systems), USP <88> (biological reactivity tests), ISO 10993 (biological evaluation of medical devices), ISO 13485 (medical device quality management), EN ISO 11607 (packaging for terminally sterilized devices) and ISO 11737 (sterilization of health care products). Certification candidates for this model are CE and ISO 9001 manufacturing; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Confirm the maximum temperature and autoclave compatibility of each polymer before use, since polypropylene tolerates about 121 °C and polystyrene does not. Avoid strong oxidising acids and solvents that cause environmental stress cracking, and test new polymer and chemical combinations before routine use. Use sterile techniques with culture ware and keep packaging intact until use, and do not reuse items intended for single use. Inspect bottles for crazing, cloudiness or odour, which can indicate chemical attack or leaching. Store plastics away from direct sunlight and heat, and keep certificates of analysis and sterility for regulated work. Where adsorption matters, run recovery checks with the analytes and the intended plastic before committing to a method.

How do I select the right Polypropylene Reagent Bottle?

Choose PP bottles for alkalis, inorganic solutions and shipping, and glass for long-term solvent storage. Confirm cap liner. RFQ: capacities, contents, cap liner, temperature and shipping needs. Provide the contents, volumes, temperature, shipping needs and cap type.

How does it compare with other Plasticware variants?

Choose the polymer from the chemistry, the temperature and the visibility needed. Polypropylene is the general-purpose choice for acids, bases and most solvents, and it can be autoclaved. Use polycarbonate where clarity and impact strength matter, but avoid it with strong alkalis and some solvents that cause stress cracking. Use polystyrene only for aqueous and culture work, since it is attacked by many solvents. Choose sterile, pyrogen-free and cell-culture-treated grades where cells, media or clinical samples are involved, and confirm the certification. Match the volume, closure and centrifuge rating to the application, and check that the resin does not adsorb the analytes of interest. For trace work, ask for leachables and extractables data, and prefer low-binding surfaces for proteins and peptides.
