Achieving rapid, repeatable reagent delivery is a fundamental requirement for high-throughput laboratory environments. Professional laboratory bottletop dispensers provide the chemical compatibility and volume precision needed to dispense aggressive acids, bases, and solvents directly from storage vessels. As a core component of our liquid handling ecosystem, these instruments support the essential dosing workflows found in our dispensing range, ensuring safety and accuracy for every technician.
Why Choose Professional Bottletop Dispensers?
Our curated collection of analog dispensers and specialized accessories is designed for durability and ease of use:
- Precision Analog Dispensing: We stock the BRAND Dispensette S Analog series, featuring volume ranges from 0.5 mL to 50 mL with integrated recirculation valves to minimize reagent waste during priming.
- Flexible Reagent Delivery: Utilize the BRAND Flexible Discharge tube with a recirculation valve to easily dispense fluids into vessels that cannot be placed directly under the dispenser.
- Inert Fluid Paths: Explore Hamilton PTFE Tubing (M6), non-tapered and designed for the most demanding chemical applications where standard tubing may fail.
- Optimized Safety Features: Select models without recirculation valves for specific protocols, all featuring the robust construction required for handling hazardous laboratory chemicals.
LabFriend supplies bottletop dispensers from the world-leading manufacturers listed in our specialized range:
- BRAND: The primary provider of the Dispensette S series, recognized globally for setting the standard in safe and accurate bottletop dispensing.
- Hamilton: Specialist in high-precision PTFE tubing and fluidic components for aggressive chemical environments.

Frequently Asked Questions
1. What is the benefit of a recirculation valve on a BRAND Dispensette S?
A recirculation valve allows you to prime the dispenser by redirecting reagent back into the bottle, eliminating air bubbles without wasting expensive or hazardous chemicals.
2. Can I dispense highly concentrated acids with these units?
Yes, the Dispensette S series is designed with high-quality materials like ceramic, PTFE, and sapphire to withstand aggressive acids, though you should always check the specific chemical compatibility chart for your reagent.
3. When should I use the flexible discharge tube accessory?
The flexible discharge tube is ideal for dispensing into tall graduated cylinders, oddly shaped flasks, or multiple vessels in a rack without moving the reagent bottle itself.
4. Are these dispensers autoclavable?
Professional bottletop dispensers like the BRAND Dispensette S are generally designed to be fully autoclavable at 121°C to ensure sterility for sensitive applications.
