Bottletop Adapter Selector & Container Compatibility
Find the right adapter for your container—quickly and accurately.
The Dispensette® S bottlep-top dispenser, Seripettor® bottle-top dispenser, Titrette® bottletop burette and QuikSip™ bottletop aspirator all connect to a wide range of bottles, canisters, and bulk containers using interchangeable adapters.
Use this page to identify the correct adapter and configuration for your setup.
Dispenser Adapter Selector
To find your adapter - select your container opening size and see:
- Required adapter(s)
- Part numbers
- Step-by-step configurations (if multiple adapters are needed)
Not sure what size you have? Measure the outer diameter of the container opening.
Container Compatibility Overview
Adapters allow compatibility with many container types.
Standard Laboratory Bottles
- GL-thread bottles (GL 22–GL 45)
- Compatible with most reagent bottles
Non-Standard Bottles & Glassware
- S-thread bottles (e.g., S 40)
- Ground glass joints (NS sizes)
- Specialty lab containers
Large Containers & Canisters
- Plastic containers with larger thread diameters
- Requires adapter combinations for proper fit
Drums & Bulk Systems
- Industrial drum bungs and threaded openings
- May require multi-step adapter configurations
- Compatible with remote dispensing setups for improved ergonomics
How to Determine Your Thread Size
To select the correct adapter:
- Measure the outer diameter of the container opening
- Identify the thread type (GL, S, or other)
- Use the tool above to match your configuration
Thread size is defined by diameter and pitch, and adapters bridge the connection to the GL 45 dispenser standard
Adapter Configuration Basics
Some containers require a single adapter, while others require a step-up configuration:
- Smaller threads, adapt up to GL 32, then to GL 45
- Industrial connections may require multiple adapters
- Material selection matters:
PP: general use
ETFE / PTFE: aggressive chemicals or solvents
The adapter finder tool automatically shows the correct configuration.
Bulk Containers and Drums
For high-volume applications, the Dispensette® S can be used with:
- Floor-standing containers
- Cabinet-stored drums
- Remote dispensing systems
In these setups:
- The dispenser can be mounted separately
- Fluid is transferred via chemical-resistant tubing
- Containers remain safely positioned off the benchtop
