BrandTech 4600140 Dispensette S Bottletop Dispenser, Analog, 1 - 10 mL Adjustable

NEW! Replacement for BrandTech Dispensette III Model Number 4701140 (Dispensette III Model)

The Dispensette S bottletop dispensers build on the 50 year history of BrandTech dispensing expertise. Continual upgrades makes this the safest and most convenient ever, while retaining the features making the Dispensette the world’s favorite bottletop dispenser. The “floating piston” design of the Dispensette S forms a zero-wear sealing system with outstanding sliding properties. Optimized flow channels make dispensing and priming even easier – particularly in instruments with large volumes.

New Features:

• Simple to mount discharge tube available with or without integrated recirculation valve
• Designed without additional sealing rings for ease of cleaning and maintenance
• Replaceable discharge valve with safety valve
• Olive-shaped filling valve for firmer attachment of filling tubes
• Improved flow technology results in faster priming
• Scalloped track for secure volume setting on analog dispensers

Mounts on Most Common Reagent Bottles

Most 1 liter and 1 quart bottles in the United States have a 33mm thread. Most 4 liter or 1 gallon bottles in the US have a 38mm thread, as do many scintillation fluid bottles. All sizes of the Dispensette S fit 45mm bottles, and come with adapters to fit 33mm and 38mm threads. Smaller Dispensette S dispensers come with additional adapters for smaller bottles. Customers using a Dispensette S with a CareFusion saline bottle as part of a Vitek system should use a 35mm adapter - catalog number 704431.

Difference Between Dispensette& Dispensette S Organic

The Dispensette S Organic has much in common with a Dispensette S, however there are two major differences. The Dispensette S Organic has a glass piston, rather than a PFA-coated piston. This optimizes it for use with concentrated acids and organic solvents that can interact with the PFA, but makes it less useful for bases. In addition, the valve spring in the Dispensette S Organic is tantalum (vs. platinum-iridium alloy) allowing it to be used with peroxides, again, at the expense of compatibility with bases. Because of the different construction and chemical compatibility, parts from a Dispensette S should not be used with a Dispensette S Organic, and vice versa.



The Brand Tech Dispensette S is a cost effective, safe, efficient, and durable bottletop dispenser that can be used to aspirate and dispense reagents directly from a reagent bottle. The Dispensette S improves safety with a recirculation valve that helps to prevent the splashing of reagents. Along with safety, it also improves overall performance and efficiency by providing a better method of measuring and transferring liquids. All Dispensette S models come with a 1-year warranty, and can last up to 10-15 years with regular care and cleaning.
