Beschrijving
TRIS, CELLPURE®, min. 99.9 %, is een hoogzuiver bufferreagens dat veel wordt gebruikt in celkweek en biochemische bereiding. Het draagt CAS-nummer 77-86-1 en EG-nummer 201-064-4, met de empirische formule C₄H₁₁NO₃ en een molaire massa van 121.14 g/mol. Fysische gegevens omvatten een dichtheid van 1.32 g/cm³ en een kookpunt van 288 °C. De CELLPURE®-kwaliteit bij minimaal 99.9 % zuiverheid past bij toepassingen die een strak gecontroleerde buffersamenstelling vereisen voor media, wasoplossingen en pH-stabiele werkreagentia in celkweekworkflows. Consistente identiteits- en zuiverheidsinformatie ondersteunt de reproduceerbare formulering van stock- en werkoplossingen. Deze TRIS-kwaliteit is bedoeld voor onderzoeks- en routinematig laboratoriumgebruik waar een goed gespecificeerde aminoalcoholbuffercomponent vereist is voor de bereiding van celkweekmedia, monsterhantering en gerelateerde biochemische protocollen.
Dit artikel maakt deel uit van Biologische buffers (Tris, HEPES, MOPS), in Buffers & pH-oplossingen.

Questions about TRIS, CELLPURE®, min. 99.9 %, 100 g, kunststof
What is this article?
TRIS, CELLPURE®, min. 99.9 %, 100 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Biologische buffers (Tris, HEPES, MOPS), inside Buffers & pH-oplossingen, in Chemicaliën.
Tris, HEPES, MOPS and their relatives hold pH in a range that cells and proteins tolerate, with a pKa near the working pH. The useful range is roughly one unit either side of the pKa. A phosphate buffer and Tris are not interchangeable in a method that names one of them, because the ion itself has effects.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
