Ensuring safe and reproducible liquid distribution is essential for consistent results. Two new bottle-top dispensers from Socorex are designed for volumes up to 25, 50 and 100 mL. The Calibrex organo 525 includes a ground glass plunger, and is suitable for organics and non-crystallizing solutions. The Calibrex solutae 530 has a PFA-coated plunger preventing plunger and barrel from seizing together, making it suitable for salt solutions, weak and strong acids, as well as bases. In-lab calibration is done by means of the integrated key under the plunger cap, and the devices easily disassemble for cleaning. Socorex Isba S.A.
