A wide range of adapters and accessories to expand your applications

Botletop accessories
Every dispenser is supplied with three adapters:
  • Smaller dispensers—with volume settings from 2.5 mlto 10 ml—connect directly to 32 mm threaded bottles and are supplied with adapters for 28 mm, 40 mm and 45 mm bottles
  • Larger dispensers—with volume settings from 25 ml to 100 ml—connect directly to 45 mm bottles and are supplied with adapters to fit 32 mm, 38 mm and 40 mm bottles
Drying tube connects directly to the back of the dispenser and protects sensitive reagents from moisture or CO2.
Extended 80 cm discharge tube is perfect for convenient repetitive dispensing into racked tubes or vials.

ChemSaver models offer you even more

Brinkmann Chemsaver Bottletop Dispenser
The ChemSaver’s recirculating safety valve channels reagent back into the bottle during priming—eliminating the waste that typically results from preparing the dispenser for use. ChemSaver models also feature finer volume adjustments for working with viscous and/or high-density solutions.

Additional product features of ChemSaver dispensers:
  • Recirculating safety valve channels reagent waste back into the bottle during priming
  • Fine adjustments make ChemSaver ideal for dispensing viscous or high-density liquids
