Calibrex organo 525 and Calibrex solutae 530

New bottle-top dispenser generation for safe and reliable dispensing up to 25, 50 and 100mL. The Calibrex^TM organo 525 model includes a ground glass plunger, best suited for organics, and non-crystallising solutions. The Calibrex^TM solutae 530 model has a PFA coated plunger preventing plunger and barrel from seizing together. This enables trouble free distribution of salt solutions, weak and strong acids, as well as bases. The choice between these two distinct models bring performance and flexibility in the laboratory. Parts in contact with liquid flow are chemically inert, providing for stability and long instrument life. A QR code printed on the instrument gives instant access to an up-to-date chemical resistance chart. Among other features, instant volume setting with a spring loaded sliding cursor that softly moves up and down scale and precisely stops at desired graduation. An alternative, classical screw button is supplied with each dispenser for easy exchange. The instrument rotates 360° for adequate positioning on the bottle. In-lab calibration by means of the integrated key, located under plunger cap. Access to calibration system is protected by a seal sticker. Disassembling for cleaning and maintenance without any tool. Autoclavable at 121°C / 250°F fully assembled. Supplied with 45mm base thread, 120mm delivery jet and stopper, 350mm feed tube, alternative screw-type volume setting button, three adapters for bottle necks 32, 38 and 40mm, each dispenser bears its own serial number and passes a stringent quality control attested by an individual certificate. Two-year warranty.
