Automatic Liquid Dispensers for Laboratories

July 4th Sale 2025

Lab bottle-top dispensers are designed to fit on top of standard laboratory reagent bottles. They are ideal for reducing the risk of spills within the lab and increasing accuracy and reliability during lab applications. Lab dispenser bottles are also excellent for minimizing contamination as they eliminate the requirement for pipetting and remove any possible cross-contamination between samples and reagents. Lab dispenser bottles are available in multiple-volume capacities, so you can dispense both small and large volumes as needed.

Bottle top dispensers are designed for convenience and comfort, can save you time, and increase productivity across the lab environment. Convenience features include easy calibration and maintenance to allow clear and precise results. Models also include interchangeable nozzles, which makes them changeable and adaptable for a range of different applications. Safety features include built-in valves to prevent spillages, leakage, or over-dispensing to enhance laboratory safety, protect the user, and keep the workspace clean.

We also provide lab filtration and lab bottles at Thomas Scientific that you may also require.
