Carboy 4-8L

Small but mighty, Nalgene 4L (1ga) carboys and 8L (2ga) lowboys safely contain and dispense valuable lab reagents. Their rugged construction can hold up to years of use under typical lab conditions. Made only from the highest-quality laboratory, pharmaceutical and food-grade plastic materials; no unnecessary additives to contaminate your valuable reagents.  

  • Low density polyethylene (LDPE), polypropylene copolymer (PPCO) and high density polyethylene (HDPE) carboys are chemically compatible with a wide range of lab reagents including most acids, bases, alcohols, aldehydes, esters, and aliphatic hydrocarbons.  
  • Polypropylene copolymer lowboys are autoclavable.

For chemical compatibility ratings by specific chemical and application temperature, consult the  Nalgene Chemical Resistance Guide, or request a copy of the printed wall chart. Nalgene carboys are made only from high-quality laboratory-grade resin materials that comply with 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 food contact. For regulatory claims  and certifications applicable to specific Nalgene carboys, please contact  Nalgene Regulatory Support.

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)

*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.
