Thermo Scientific Carboys for Buffers, Media, and DI/RO Water

Thermo Fisher (Nalgene) carboys give you reliable, large-volume containers for buffers, media, and DI/RO water across research, QA/QC, and bioprocess settings. This collection page helps you shortlist by application, material, capacity, and accessories—then finish with compliant documentation. As a distributor, Iright can source the full Thermo Fisher portfolio and coordinate bulk or mixed-material buys.

Choose by Application: Buffers, Cell-Culture Media, and DI/RO Water

When you match the container to its use case, you minimize cleaning time and handling risks. Start with your liquid type, sterility needs, and whether you’ll dispense daily. Use the quick selector below to jump into the right subset of products and accessories.

• Buffer preparation & general reagents → PP/PPCO (autoclavable, rugged) or HDPE (economical, chemical-resistant) carboys; add vented caps for smoother pours.
  
• Cell-culture media in cleanrooms → Sterile Biotainer™ PC carboys (ready-to-use, validated docs) or PETG single-use bottles/carboys to reduce cleaning and revalidation.
  
• DI/RO water storage & everyday dispensing → HDPE or fluorinated HDPE with spigot for drip-free distribution to benches. 

One-click filters to configure on page: Autoclavable (Yes), Sterile (Yes), With Spigot (Yes), Capacity (10–20 L / 20–50 L), Material (HDPE/PP/PC/PETG).

Material & Sterilization Guide: HDPE, PP/PPCO, PC/Clearboy™, Sterile PETG

Material choice governs sterilization, clarity, and extractables. Use the matrix to weigh transparency versus ruggedness and whether you want reusable (autoclavable) or cleanroom-ready single-use packaging.

Tip: For aseptic transfers, pair carboys with ported/vented closures and tubing sets designed for Biotainer™ bottles/carboys (1–20 L).

Capacities & Form Factors: 5–75 L, Wide/Narrow-Mouth, With/Without Spigot

Capacity affects handling and cycle time: smaller vessels simplify lifting and autoclaving; larger ones minimize refills. Mouth style determines how easily you add powders or insert tubing. Spigots speed routine dispensing but require periodic inspection and cleaning.

• Capacity bands: 5–10 L (benchtop prep), 10–20 L (daily distribution), 20–50 L (room storage), 50–75 L (central reagent bank).
• Mouth type: Wide-mouth for powder additions and cleaning; narrow-mouth for splash control.
• Spigot option: “With spigot” for routine DI/RO water or buffer dispense; “without” for transport or when you’ll use top-mounted transfer sets.

Form-factor matrix (example guidance):

• 10–20 L, daily dispense, reusable → PP/PC with spigot.
  
• 20 L solvents → Fluorinated HDPE with spigot.
  
• 20 L cleanroom single-use media → Sterile PC Biotainer™ carboy.

Featured Nalgene Lines: Reusable PP/PC and Single-Use PETG Carboys

Within Thermo Fisher’s lineup you’ll find long-standing Nalgene families covering both reusable and single-use workflows. The examples below show typical options you’ll encounter while filtering this collection.

• Nalgene HDPE Rectangular Carboy with Spigot — robust, economical DI/RO water storage and general dispensing. (Cat. 2320-0050, 20 L) 

• Nalgene Polypropylene Carboy with Spigot — autoclavable reusable storage for buffers and media. (Cat. 2319-0020, 10 L; 2319-0130, 50 L) 

• Nalgene PP Rectangular Carboy with Spigot — space-efficient “banking” of reagents. (Cat. 2321-0020, 9 L; 2321-0050, 20 L) 

• Nalgene Polycarbonate Clearboy™ Carboy with Spigot — clear, autoclavable; ideal when visual inspection matters. (Cat. 2322-0020, 9 L; 2322-0050, 20 L)

• Nalgene Polycarbonate Biotainer™ Carboy (Sterile) — square, ready-to-use for cleanrooms. (Cat. 3423-42, 20 L)

• Nalgene Fluorinated HDPE Carboy with Spigot — improved solvent resistance for certain organics. (Cat. DS2327-0050, 20 L)

Caps, Vents & Accessories: Vented Caps, Spigots, Tubing Adapters

Accessories complete the system and can be the difference between neat dispensing and air-glugging or contamination risk. Choose parts designed for your bottle/carboy family and mouth size to preserve leakproof performance and validation.

• Vented closures for smoother flow and reduced vacuum formation during pours.

• Spare spigots with gaskets sized to your carboy line; inspect routinely and replace on schedule.

• Ported/aseptic transfer caps for Biotainer™ bottles and carboys (fit 1–20 L, PC/PETG) to support sterile fluid paths.

• Tubing adapters that match your ID/OD and closure thread; set up quick-connects for repeatable transfers.

Compatibility tip: Keep an internal cheat-sheet mapping each carboy’s closure size (e.g., 48 mm on many Biotainers) to the correct ported cap and tubing set to avoid ad-hoc fittings.

Compliance & Cleanroom Notes: Autoclave, Sterility, and Documentation

Regulated environments demand predictable materials, sterilization, and paperwork. Build your shortlist with products that align to your validation strategy and storage conditions.

• Reusable & autoclavable: PP/PPCO and PC carboys tolerate autoclave cycles—verify cycle limits and cooling steps in your SOPs. 

• Sterile single-use: Biotainer™ PC (and PETG bottles/carboys) are gamma-irradiated, supplied sterile (SAL 10⁻⁶) with ready documentation, reducing cleaning and revalidation costs.

• Solvent handling: Use fluorinated HDPE variants for certain solvent storage and dispensing.

• Traceability: Download Certificates of Compliance and sterility statements from the product pages and maintain batch records alongside your media prep logs.

FAQ: Autoclavable Models, Chemical Compatibility, Mouth Types & Leaks

Q1. Which carboys are autoclavable?
PP/PPCO and PC/Clearboy™ carboys are designed for autoclaving; HDPE is generally not, and PETG Biotainer™ units are supplied sterile for single-use (not autoclavable). Always follow Thermo Fisher guidance and your SOPs.

Q2. What should I pick for cleanroom media storage?
Choose sterile PC Biotainer™ carboys or PETG sterile bottles/carboys to minimize cleaning, with compatible ported closures for aseptic transfers.

Q3. Wide-mouth or narrow-mouth?
Pick wide-mouth for powder additions and easier cleaning; choose narrow-mouth when splash control and smaller closure hardware matter. (Select the “Mouth” facet to filter quickly.)

Q4. How do I prevent drips and leaks from spigots?
Use the manufacturer’s spigot for your family and mouth size, replace gaskets on schedule, and avoid overtightening. For sterile lines, use ported caps and tubing instead of open-air spigots. 

Q5. Are there solvent-compatible options?
Yes—fluorinated HDPE carboys are designed for dispensing a variety of solvents; always check chemical compatibility tables for your specific solvent mix.
