Dropper Bottles

Thermo Scientific Nalgene LDPE dropper bottles with tethered caps are our most popular lab reagent drop dispensing bottles. Available in sizes ranging from 15mL to 250mL, and made from high quality lab grade LDPE plastic resin materials, these droppers are useful for containing and dispensing a wide range of lab reagents including most acids, bases and alcohols.

For faster dispensing by the drop or in a stream, and to access harder-to-reach places with your reagent, try the Nalgene dropper bottle with our bulb-transfer pipet style cap assembly.

Need a dropper bottle you can sterilize? The Nalgene polypropylene copolymer (PPCO) dropper bottle is autoclavable. It's also compatible with a wide range of lab chemicals. This bottle dispenses in a fine, steady stream rather than drop-wise.

For more aggressive chemicals or high purity reagent dispensing, choose the Nalgene fluoropolymer FEP dropper. Made from high purity FEP resin material, these droppers are compatible with virtually any chemical and are usable over an incredibly wide temperature range of -105°C to +150°C. Dispenses only one drop at a time. Captive spout cap stays in place when the bottle is squeezed preventing accidental dispensing.

All of our Nalgene dropper bottles are manufactured in our ISO 13485:2003 registered manufacturing facilities. Most of our plastic resin materials are DMF registered and meet a number of regulatory specifications including: USP Class VI, EP monographs, EU food-contact directives, CONEG, RoHS, CA Prop 65, SARA Title III Sec. 313, and 21 CFR pt 177. For regulatory claims and certifications applicable to specific Nalgene dropper bottles, contact  Nalgene Regulatory Support.

Footnote:
1. HDPE and LDPE are acceptable for: nonacid, aqueous products; may contain salt, sugar or both (pH above 5.0). Dairy products and modifications; oil-in-water emulsions, high or low fat. Moist bakery products with surface containing no free fat or oil. Dry solids with the surfaces containing no free fat or oil (no end-test required) and under all conditions as described in Table 2 of FDA Regulation 177.1520 except condition A - high temperature sterilization (e.g. over 100° C / 212° F)

*Dispensing tip drop volumes are based on water; viscosity affects drop size.
**The term “leakproof” applies to Thermo Scientific Nalgene products that meet the following criteria: a) Bottle/flask/funnel closure systems with closures smaller than 100mm, after they are filled with water, inverted, withstand air pressure of 2psig for 2 minutes, and no water escapes;. b) Bottle/funnel/flask closure systems of larger than 100mm after they are filled with water, inverted for 15 minutes, and no water escapes. Note: these tests, using other liquids, may not yield the same results. To ensure safe usage, customers are advised to test Thermo Scientific Nalgene bottles and closures under conditions of their planned applications. Thermo Scientific Nalgene products are leakproof at ambient temperature and pressure when used with their Nalgene closures.
