Buffer solution with dosing cap pH 7,00 (25 °C) green is a technical pH buffer prepared according to DIN 19267 and traceable to standard reference materials from PTB and NIST. At 25 °C it provides a defined neutral value of pH 7,00, widely used for calibration and intermediate checks of pH electrodes and meters in analytical, research and quality-control laboratories. The green colour coding enables quick visual distinction from acidic or alkaline standards and reduces the risk of incorrect buffer selection during routine work. This 250 ml pack comes in a natural HDPE dosing bottle with a 28 mm guarantee closure. The dosing cap supports convenient delivery of 20 ml and 25 ml volumes, facilitating consistent aliquots for electrode calibration. From manufacturer IDL GmbH, the solution is intended for technical laboratory applications requiring reference-traceable buffer values. The compact 250 ml format suits benches with moderate throughput, while the HDPE bottle and guarantee closure offer practical handling and integrity until first opening. A dependable green pH 7,00 buffer whenever a ready-to-use neutral standard with integrated dosing is required.

Questions about Buffer solution in handy dispensing bottle pH 7,00 (25°C) green, 250 ml
What is this article?
Buffer solution in handy dispensing bottle pH 7,00 (25°C) green, 250 ml is the article on this page. Luminix Health distributes IDL GmbH for laboratory use. It sits in Peristaltic & dosing pumps, inside Pumps, vacuum & evaporation, in Instrumenten.
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.
