The Labmax™ bottle top dispenser has been developed through extensive testing and input from end users. The result is an easy to use system with a variety of important features.

Spill Prevention Feature

The unique closed circuit air purging system allows air and bubbles to be eliminated from the dispenser without loss of valuable reagent. The reagent "guard valve" prevents accidental discharge of reagent when the dispenser is not in use. A simple turn of the operations mode selector activates this safety feature. Eliminating the need for discharge tube caps. The exclusive Integrated Swivel Neck allows the discharge tube to be turned 360° for convenient dispensing without affecting the connection to the bottle.

Locking Rocker Switch

The Dispensers are fully autoclavable to 121°C for sterilization. The Labmax™ can be disassembled quickly and easily for thorough cleaning. Quick and accurate volume adjustment is easy with the locking rocker switch. The zero point is manufactured into the Labmax™; calibration is not necessary, even after disassembly and cleaning. ISO 9001 Certification has been achieved in the design, development and manufacturing stages of the Labmax™. All Labmax™ dispensers feature a dated mark for compliance with ISO 9001 procedures.

Dispensette S Trace Analysis Bottle Top Dispensers

• 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

The Dispensette^® S Trace Analysis is the next generation bottletop dispenser for precise volume dispensing of high-purity media for trace analysis. It is especially suited for dispensing acids, bases and hydrogen peroxide in the volume range from 1 to 10 mL. The components of the fluid path have been selected to only contain the highest purity materials, such as fluoroplastics and sapphire. The result is a trace metal content of dispensed liquid generally in the low ppb range, or even in the low ppt range, depending on the application. Both platinum-iridium and tantalum valve springs are available for application compatibility.

Dispensette S Analog Bottle Top Dispensers

• The GL45mm standard thread, plus included adapters, fit most common lab bottles
• The valve block rotates 360° so the bottle label always faces the user for safety
• Telescoping filling tube adjusts to different bottle sizes
• Easy to disassemble for cleaning
• 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
• Scalloped track for secure volume setting on analog dispensers

Dispensette® S bottletop dispensers build on the 50 year history of BRAND® 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.

The Dispensette^® S bottletop dispenser is supplied with: discharge tube, valve mounting/calibration tool, polypropylene adapters, telescoping filling tube, recirculation tube (optional), performance certificate, operating manual, and one year warranty.

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.
