Accurate dispensing from a range of bottle sizes
Labquest Bottle Top Dispensers by Borosil
Borosil Bottle Top Dispensers offer accurate dispensing with enhanced safety and DIY calibration. The Pinnacle model offers Borosils patented recirculation valve, allowing for efficient liquid handling solutions. They are also Fully Autoclavable, easy to recalibrate and offer convenient QR code based compatability for all users.
Calibrated for Accuracy: Calibrated in accordance with ISO 8655 standards, ensuring precise dispensing performance for laboratory applications. Each unit includes a Certificate of Conformity, verifying compliance with quality and accuracy standards.
What is the difference between Research & Pinnacle with RCV valve?
The recirculation valve allows you to prime the Labquest Dispenser without wasting any of your chemical, in Pinnacle Models. In Research Models, operating without a recirculation valve the initial priming dispenses would be discarded out.
What can I dispense with the Labquest Dispensers?
Labquest Dispensers facilitate dispensing various reagents, solvents & acids with safety & precision.
Labquest dispensers wetted parts constructed from Borosilicate Glass, PTFE Piston, PFA Valve & FEP tubes can dispense nearly any laboratory chemical/reagent having density up to 2.2gm/cc, vapour pressure 600 m bar.
Limitations of using dispensers include:
• Liquids that attack FEP, PFA and PTFE (e.g. dissolved Sodium Azide)
• Liquids that attack borosilicate glass (e.g. Hydrofluoric acid)
• Hydrochloric acid > 40% and Nitric acid >70%
Additional Pinnacle model feature: recirculation valve that prevents reagent loss while priming.
Autoclavable: Fully
