Description
pH buffer solution pH 4,00 ± 0,01 is supplied in a 500 ml Twin-Neck dosing bottle designed for clean, controlled dispensing during electrode calibration. The separate compartment layout removes the need for a second vessel in the calibration step and helps preserve the purity of the remaining buffer. The coloured formulation aids visual identification and lowers the chance of selecting the wrong standard in multi-buffer sequences. A pH-versus-temperature table on the label supports accurate use across typical laboratory temperatures. Traceable SRM certificates according to NIST are available, consistent with metrological practice for reference buffers. This LABKEM preparation from manufacturer Labbox is suited to routine acidic-range calibration, instrument verification and quality-control work. After opening, the solution should be used within 12 to 15 months. Net weight is 0,600 kg for the 500 ml fill. The dosing-bottle format is practical for busy benches where contamination control and ease of handling matter.
This article is part of Peristaltic & dosing pumps, in Pumps, vacuum & evaporation.

Questions about pH Buffer solution with measuring chamber, pH 4,00 ± 0,01, 500 ml
What is this article?
pH Buffer solution with measuring chamber, pH 4,00 ± 0,01, 500 ml is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Peristaltic & dosing pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A peristaltic pump moves liquid by rollers squeezing a tube, so the liquid never touches the mechanism. Flow depends on the tube bore and the speed. A dosing pump aims at a set volume. The tube is the consumable, and the chemical has to be one that tube survives.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
