Thermo Fisher Bottles for Labs — GL45 Media, PETG Sterile & Nalgene Carboys

Thermo Fisher bottles cover day-to-day lab storage, media prep, sterile transfer, washing, centrifugation, and bulk liquid handling. This Collection brings the range together so you can choose by material, neck standard, sterility level, and capacity—then jump straight to the right sub-series. As your distributor partner, Iright supplies a wide selection of Thermo Fisher (Thermo Scientific/Nalgene) bottles and can provide quotes, source documents, and ship to your lab.

What This Collection Covers — Thermo Fisher Lab Bottles at Iright

You’ll find practical groupings that mirror how you buy and use bottles, not just how they’re named. Start with material and neck/cap fit, confirm sterility needs, then choose the sub-range that matches your workflow. Each section includes quick specs, use notes, and representative SKUs you can verify before purchase.

• Day-to-day bottles: GL45 media (glass/plastic), PETG sterile media bottles, wash bottles

• Process bottles: Oak Ridge/PPCO centrifuge bottles, Clearboy™ and PP carboys

• Accessories: GL45/83B closures, vented/PTFE-lined caps, bottle-top filters

Material Guide: Glass vs PP/PPCO vs PETG vs HDPE

Choosing material is mostly about chemical compatibility, heat/sterilization, and reusability. Glass excels for solvents and heat; PP/PPCO delivers rugged, autoclavable plastic; PETG shines for sterile, single-use workflows; HDPE/LDPE are great for general storage and dispensing. Use the table to narrow fast, then confirm on the product page.

Neck & Caps: GL45 vs Wide-Neck, Vented Caps & PTFE-Lined Caps

Neck standards drive compatibility with closures, tubing caps, and bottle-top devices. GL45 is the lab workhorse for media bottles and filtration units; wide-neck (e.g., 83B) is common on carboys for fast filling and hose connections. Pair the neck with the right cap—solid, vented, PTFE-lined, or multi-port—for leak-free, sterile workflows.

• GL45 ecosystem. Works with bottle-top filters and multi-port process closures, e.g., Nalgene™ Top Works™ GL45, 3-port closure (2132-1003) for rapid-flow or transfer setups.

• 83B wide-neck for carboys. Spacious opening for bulk media and tubing; common on Nalgene™ PP carboys. 

• PTFE-lined caps. For aggressive solvents or odor control, choose caps with inert liners on compatible bottles (see individual product pages for liner details and compatibility).

Sterility & Cleanliness: Gamma-Irradiated vs Autoclavable Options

Decide first if you need single-use sterile (ready out of the bag) or reusable autoclavable (sterilized by you between runs). PETG sterile bottles are supplied gamma-irradiated and nonpyrogenic; reusable glass/PP/PPCO lines are engineered to tolerate autoclaving when used as directed on the datasheet.

• Single-use PETG sterile: Supplied sterile, shrink-wrapped; ideal for aseptic media storage/transfer; examples in the next section.

• Reusable/autoclavable: Borosilicate glass media bottles, PP/PPCO centrifuge bottles, and carboys indicate autoclave suitability on their pages. Follow venting guidance to avoid deformation and leaks.

Sub-Ranges at a Glance: GL45 Media, Sterile PETG, Wash, Centrifuge & Carboys

Below is a quick tour so you can jump straight to what you need. Each bullet highlights typical use and one representative SKU (verify specs and certificates on the product page before ordering).

• GL45 glass media/solvent bottles — Resistant to heat and many solvents; compatible with bottle-top filters. Representative SKUs: 045900 (1 L GL45 coated glass) and 045901 (2 L GL45 coated glass) used on Thermo Scientific™ Dionex™ systems.

• PETG sterile media bottles (square) — Clear, gamma-irradiated, low extractables; ideal for sterile media or buffer. Representative SKU: 342020-1000 (1 L, 38-430 closure) in the Nalgene™ Square PETG series.

• LDPE wash bottles — Squeeze bottles for DI water and common lab fluids; through-the-top closure and molded stem. Representative SKU: 2407-0500 (500 mL, 53 mm).

• PPCO centrifuge bottles (Oak Ridge/process) — Rugged, reusable centrifuge bottles for high-g or tri-clamp transfer variants. Representative SKU: 3120-0500 (500 mL PPCO centrifuge bottle).

• Carboys (PP/Clearboy™ PC) — Bulk storage and media prep with wide-neck closures; reusable, and many models are autoclavable. Representative SKUs: 2250-0050 (20 L PP carboy, 83B cap) and 2251-0020 (10 L Clearboy™ PC carboy).

Care & Sterilization Notes for Thermo Fisher Bottles

Proper care keeps bottles reliable and reduces contamination risks. The points below cover the most common pitfalls and how to avoid them. If you’re building a validated process, request product certificates and follow the datasheet explicitly.

• Vent for autoclave. For PP/PC carboys and PPCO bottles, rest the cap loosely to prevent pressure buildup and deformation; tighten after cool-down.

• Match the cap to the chemistry. Pair solvent storage with compatible liners (e.g., PTFE-lined caps) and avoid soft liners for aggressive organics.

• Separate sterile workflows. Use gamma-sterile PETG for single-use aseptic handling; do not steam-autoclave PETG bottles.

• Use the right neck. GL45 is ideal for filtration and multi-port closures; 83B wide-neck eases bulk filling and tubing connections on carboys.

Thermo Fisher Bottles: Frequently Asked Questions

This FAQ focuses on practical purchase and use decisions—sterility, fit, and compatibility—so your team can move forward without guesswork.

Q1. Can PETG sterile bottles be steam-autoclaved?
No. PETG bottles are supplied gamma-irradiated and are not intended for steam autoclave cycles; choose glass or PP/PPCO if you need reusable sterilization.

Q2. What’s the difference between GL45 and 83B?
GL45 is a threaded neck standard common on media bottles and filtration accessories. 83B is a wide-neck carboy closure standard favored for bulk filling and hose connections.

Q3. I need a 500 mL squeeze bottle for DI water—what should I pick?
Choose an LDPE wash bottle (e.g., 2407-0500, 500 mL), which has a molded stem and through-the-top closure for smooth dispensing.

Q4. Which bottle type fits bottle-top filters?
Glass media bottles with GL45 necks pair well with bottle-top filters and reusable filter tops such as Nalgene™ Reusable Bottle Top Filters (DS0320 series).

Q5. Do you have a rugged 20 L option for autoclaved media?
Yes—Nalgene™ 2250-0050 (PP carboy, 20 L, 83B cap) is designed for bulk media/chemical storage and indicates autoclavability on its page. Vent caps during cycles per guidance.
