Globe Scientific Bottle Top Dispenser Thread Adaptor - GBTD-ADP Series | For Diamond SureFlow

Your reagent bottle has a 40 mm neck and your dispenser shipped with a 38 mm adapter — now what? Instead of returning the entire dispenser or jerry-rigging a seal with parafilm, the Globe Scientific Bottle Top Dispenser Adaptor lets you match any Diamond SureFlow dispenser to bottles with 28 mm, 38 mm, 40 mm, or 45 mm thread sizes. These precision-molded adapters create an airtight seal between the dispenser and the bottle neck, preventing reagent leaks, vapor escape, and contamination. Each adapter is sold individually, making it easy to stock the specific sizes your lab needs without buying a full accessory kit. Whether you are retrofitting a SureFlow dispenser to a Schott Duran bottle with a GL45 thread or adapting it to a narrow-neck Winchester with a 28 mm opening, these adapters ensure a secure, leak-free connection every time. Compatible with both standard (GBTD) and recirculation (GBTD-R) Diamond SureFlow models across all volume ranges.

Features and Benefits

• Expand Bottle Compatibility: Each adapter converts your Diamond SureFlow dispenser to fit a different bottle thread size (28 mm, 38 mm, 40 mm, or 45 mm), extending compatibility beyond the four adapters included with every new dispenser.

• Airtight Seal: Precision-molded threads create a tight, vapor-resistant connection between the dispenser and the bottle neck, preventing reagent evaporation and atmospheric contamination of sensitive chemicals.

• Universal SureFlow Compatibility: Works with every Diamond SureFlow dispenser — both the standard GBTD series and the recirculating GBTD-R series — across all eight volume ranges from 0.25 mL to 100 mL.

• Sold Individually: Purchase only the thread sizes your lab actually needs. No forced bundles, no wasted inventory — order one adapter or stock multiples for shared dispenser stations.

• Durable Construction: Engineered to withstand repeated installation and removal cycles without thread degradation, maintaining a reliable seal over the life of your dispenser.

Laboratory Applications

• Fitting a Diamond SureFlow dispenser to GL45-threaded Schott Duran or Corning glass media bottles commonly used in cell culture and microbiology labs for autoclaved media storage

• Adapting dispensers to narrow-neck 28 mm Winchester bottles and solvent containers used in analytical chemistry for HPLC mobile phase preparation

• Equipping shared dispensing stations in teaching laboratories where multiple bottle formats from different reagent suppliers require quick adapter swaps between classes

Frequently Asked Questions

Does the Diamond SureFlow dispenser already come with thread adapters?
Yes. Every new SureFlow dispenser (both standard and recirculation models) ships with four adapters: 28 mm, 33 mm, 36 mm, and 38 mm. These individually sold adapters (GBTD-ADP series) provide the 40 mm and 45 mm sizes not included in the box, plus replacement 28 mm and 38 mm units if your originals are lost or damaged.

Which adapter do I need for a GL45 bottle?
The 45 mm adapter (GBTD-ADP-45) fits GL45-threaded bottles, which is the most common thread standard for laboratory glass media bottles manufactured by Schott Duran, Corning, and similar brands.

Are these adapters autoclavable?
The adapters are designed to withstand the operating conditions of the Diamond SureFlow dispenser system. For specific autoclave compatibility, consult the Globe Scientific product documentation or contact their technical support team to confirm the adapter material can handle your sterilization protocol.
