The Swiss manufacturer Socorex has announced the release of a new bottle-top dispenser generation intended for the safe and reproducible liquid distribution of volumes up to 25, 50 and 100 mL.
The CalibrexTM organo 525 model includes a ground glass plunger, best suited for organics, and non-crystallizing solutions. The CalibrexTM 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 the two colour-coded organo 525 and solutae 530 models with dedicated chemical resistance increases dispensing flexibility in the laboratory. Parts in contact with liquid flow are chemically inert, providing 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.
In-lab calibration is by means of the integrated key, located under the plunger cap. The access to the calibration system is protected by a seal sticker. The units are autoclavable at 121°C / 250°F fully assembled.
