Easy and reliable dispensing from almost any size reagent bottle
Available in a variety sizes, ranging from 0.1 mL to 50 mL in volume, Metrohm Brinkmann Bottletop Dispensers make it easy to dispense reagents fast. These dispensers come in fixed-volume and adjustable-volume models, and they’re perfect for dispensing aliquots of liquid from large supply bottles. Extracting dispensing volumes is easy and simple to reproduce, with absolutely no reagent waste.
The telescoping filling tube easily adjusts to fit the reagent bottle without cutting, and is simple to readjust with a rapid volume setting and precise graduation scale. Dispensers rotate a total of 360° for easy access to volume adjustment and to get the most convenient position. All models are designed for simple cleaning and easy maintenance in the lab, and include a certificate of calibration.
These dispensers will save you time in cleanup, as they eliminate all reagent waste. The PTFE resin "wiping" piston seal wipes the reagent out of the cylinder with each stroke, leaving behind no trace of residue. This eliminates problems associated with piston-swelling and freezing, as well as reagent crystallization. The grooved "slide-n-lock" volume adjustment allows you to set the volume quickly and easily, but prevents accidental changes while in use.
In addition to the great features listed above, the ChemSaver™ Bottletop Dispenser contains a recirculating safety valve that channels the reagent back into the bottle, eliminating reagent waste that would normally occur during unit priming. This valve can also be closed to prevent accidental dispensing. Versatile and convenient, the ChemSaver can be calibrated for finer volume adjustments necessary during work with viscous or high-density reagents.
Bottletop dispensers provide the highest quality of protection, especially during work with solvents or other caustic liquids. For safety that can’t be beat, they feature superior chemical resistance and are fully autoclavable (20 min, 121°C).
Dispensers 2.5 mL - 10 mL fit onto 32mm bottles and include adapters for 28mm, 40mm, and 45mm bottles. Dispensers 25mL to 50 mL fit onto 45 mm bottles and include adapters for 32 mm, 38mm, and 40 mm bottles. Each dispenser includes three adapters.
