Frequently Asked Questions Reagent Bottles (Narrow Mouth) - LDPE

The main advantage of LDPE (Low Density Polyethylene) is its flexibility. LDPE bottles can be gently squeezed to dispense contents, making them ideal for use as wash bottles or for drop-wise reagent addition. HDPE is more rigid and offers higher impact strength but cannot be easily squeezed. Both materials offer excellent chemical resistance, but LDPE provides the added benefit of flexible dispensing.

No, these LDPE reagent bottles are specifically labeled as not autoclavable. LDPE has a lower melting point (approximately 105-115°C) compared to other materials like PP, and will deform or melt under standard autoclaving conditions (121°C). They are designed for ambient temperature storage of non-sterile reagents.

The seal ring inside the PP cap creates a totally leak proof closure even when the bottle is squeezed during use. This ensures that liquid only exits through the intended opening when pressure is applied, and no leakage occurs from the cap area. The seal remains effective through repeated opening, closing, and squeezing cycles.

LDPE offers excellent chemical resistance to aqueous solutions, dilute acids, dilute bases, alcohols, and many laboratory buffers. However, it may not be suitable for strong oxidizing agents, some organic solvents like toluene, xylene, or chloroform, and certain hydrocarbons. LDPE can also be permeable to some gases and volatile organic compounds over time. Always consult chemical compatibility charts for specific reagents.

Yes, these LDPE bottles are excellent for use as wash bottles for many common laboratory solvents like acetone, ethanol, methanol, and isopropanol. The flexibility allows for easy squeezing, and the chemical resistance ensures compatibility. However, always verify compatibility with specific solvents, as some aggressive solvents may cause swelling or degradation of LDPE over time.

This packaging strategy reflects typical laboratory usage. Smaller volumes (8 ml to 60 ml) are often used for multiple aliquots, sample storage, or preparing multiple reagent batches, requiring higher quantities. Larger volumes (125 ml to 1000 ml) are typically used for bulk storage of frequently used solutions where fewer bottles are needed. This approach provides the best value and reduces unnecessary packaging waste.

These bottles are designed for reusable applications. To clean, simply disassemble the cap and rinse thoroughly with distilled water or a suitable solvent compatible with LDPE. For stubborn residues, mild laboratory detergents can be used. Allow all components to air dry completely before refilling to prevent dilution or contamination of new reagents. Avoid using abrasive cleaners that could scratch the interior surface.

These LDPE narrow mouth bottles are available in eight sizes: 8 ml, 15 ml, 30 ml, 60 ml, 125 ml, 250 ml, 500 ml, and 1000 ml. The smaller sizes (8 ml to 60 ml) come in packs of 100 pieces, medium sizes (125 ml to 500 ml) in packs of 12 pieces, and the 1000 ml size in packs of 6 pieces.
