NALGENE

Nalgene bottles are supplied in HDPE, LDPE, PPCO, polypropylene, polycarbonate, PMP, and fluoropolymer resins. Selection depends on chemical compatibility, temperature, and optical requirements. HDPE is used for general aqueous and many solvent applications. PPCO and polypropylene are autoclavable and translucent. LDPE is flexible for squeeze dispensing and is often chosen when trace-metal contamination is a concern. Polycarbonate provides clarity and impact resistance for visual inspection. PMP offers high-temperature resistance and high transparency. Confirm the specific resin against the chemical being stored, and check whether the closure material matches the bottle resin for the intended temperature and sterilization cycle.

Yes. Nalgene bottle top filters in the 3G Electric catalog include PES membrane units with 0.2 µm pore size in 75 mm diameter with 500 mL upper capacity, and 90 mm diameter with 1 L upper capacity. These are vacuum-assisted devices intended for filtration of aqueous solutions such as laboratory media, buffers, and reagents. The membrane material is PES, and the units are supplied without a stopper. For other pore sizes or membrane materials, match the Nalgene MPN to the required specification. Pore size and diameter determine flow rate and throughput, so select based on the volume to be filtered and the particle size to be retained.

Nalgene nylon membrane filters are non-sterile discs used for laboratory filtration of aqueous and organic solvents. The catalog includes 47 mm diameter discs in 0.2 µm and 0.45 µm pore sizes, with MPNs DS0215-4020 and DS0215-4045 respectively. Typical applications include particle analysis, solvent clarification, and general filtration where nylon compatibility is acceptable. Nylon is chosen for its mechanical strength and broad solvent resistance, but it is not suitable for all analytes; check compatibility for the specific solvent and sample matrix. These filters are supplied non-sterile and are typically used with a vacuum or pressure filtration apparatus sized for 47 mm discs.

Nalgene rectangular lab trays in polypropylene are constructed with heavy walls intended to withstand rugged use and repeated autoclaving. A representative unit has a 20 L capacity and measures 21 3/8 in by 17 1/8 in. The trays are tapered for nesting to save space when not in use. Autoclave cycles should follow the resin's temperature limits and the facility's standard cycle parameters. Repeated autoclaving can affect any polymer over time, so inspect trays for cracking, warping, or stress whitening and replace as needed. These trays are used for drying and sterilizing instruments and labware in laboratory settings.

Nalgene polycarbonate rectangular bottles are available with and without closures depending on the item. For example, the 30 mL graduated bottle includes an attached 20 mm screw closure to prevent cap loss, while the 500 mL and 1 L graduated bottles are supplied without a closure. All three are clear, colorless, graduated, and square in shape. When ordering, confirm the closure inclusion field for the specific MPN. If a closure is not included, select a compatible screw closure in the correct diameter and material for the application. Polycarbonate provides clarity for visual inspection but has limited resistance to some solvents and should not be autoclaved repeatedly.

3G Electric lists 616 Nalgene SKUs across bottles, wash bottles, trays, filters, and related labware, including HDPE, PPCO, and LDPE options. Orders are quoted by part number, and logistics support is provided for delivery to laboratory, plant, and field locations. Buyers can specify material, capacity, closure type, pore size, and membrane diameter, and 3G Electric matches these to Nalgene MPNs. For recurring consumables such as membrane filters and bottles, provide the MPN and required quantity for a quote. 3G Electric ships globally and does not restrict orders to a single country or region.
