Bottle top dispensers

High quality BRAND® Dispensette®S and seripettor® bottle-top dispensers bring efficiencies to all dispensing applications, using solvents, acids, alkalis and saline solutions. There is a choice of analogue and digital models, together with models for specific applications including: organic and trace analysis dispensing. The volume ranges are 0.1-1.0ml to 10-100ml, all factory calibrated and certified in accordance with ISO 8655:2022 for regulatory compliance.
All models are easy to prime, clean, service and calibrate without the need for special tools or training, with easy-to-follow instructions included.
Bottle-top dispensers are a safer alternative to glass graduated pipettes, and deliver efficiencies for multiple dispensing with optimal accuracy and precision. Dispensettes® are available with a recirculation valve for efficient liquid priming with minimal wastage. Threaded adaptors are included for all popular bottle sizes.
Useful, time-saving accessories are available including: extended flexible PTFE dispense tubing for filling racks of tubes and vials, to minimise the risk of splashes or spills.

Bottle top burettes

High quality BRAND® Titrette® bottle-top digital burettes meet Class A standards (DIN ISO EN 385) for glass burettes and ISO 8655:2022 standards for bottle-top burettes. Potential safety risks to users of traditional laboratory glassware are minimised.
The liquid pathway is highly chemically inert, making the Titrette® ideal for efficiently dispensing a wide range of liquids – excluding HF. 3 sizes are available: 10ml, 25ml and 50ml, with sensitive drop-by-drop titration down to 20ul.
All models are easy to prime, clean, service and calibrate without the need for special tools or training, with easy-to-follow instructions included. Threaded adaptors are included for all popular bottle sizes.
For GLP regulated laboratories, the optional PC interface is available, to eliminate transcription errors. With each data transfer, the burette sends the titrated volume, the serial number of the instrument, the nominal volume and the adjustment value, as well as the next scheduled calibration date. Thus, all raw data is collected and displayed together with actual date/time stamp from the PC.
