Product Overview
Cesium hydroxide, 99.9% purity on a trace metal basis, is a highly reactive alkaline solution supplied as a 50 wt% aqueous formulation. This product is engineered for applications demanding ultra-low metal contamination, ensuring reliable results in sensitive analytical procedures. The solution’s standardized concentration eliminates variability, while the cesium base provides superior solubility compared to potassium or sodium analogs. Its high purity grade is achieved through rigorous purification processes, including multi-stage distillation and trace metal analysis via ICP-MS. The product is packaged in HDPE bottles with tamper-evident seals to prevent atmospheric contamination, with each batch accompanied by a certificate of analysis detailing impurity profiles. The 50% concentration offers an optimal balance between reactivity and ease of handling, reducing the need for dilution in most protocols. Compatibility with glass and PTFE labware makes it versatile for various experimental setups. Storage stability is enhanced through the addition of proprietary stabilizers that inhibit carbonate formation without introducing detectable impurities.
FAQs
1. What is the shelf life of this cesium hydroxide solution when stored unopened?
The unopened solution maintains its specified purity for 24 months from the date of manufacture when stored at 15-25°C in its original container. The HDPE bottle’s oxygen barrier properties significantly reduce degradation from atmospheric exposure.
2. Can this product be used with standard borosilicate glassware?
While compatible with borosilicate glass for short-term use, prolonged contact may cause slight etching due to the high pH. For long-term storage or repeated use, PTFE or PFA containers are recommended to prevent silicon leaching from the glass.
3. What is the typical carbonate content in this solution?
Batch-specific certificates of analysis report carbonate levels below 0.5% by weight, achieved through controlled atmosphere packaging and the inclusion of carbonate scavengers in the formulation.
4. How does the 50% concentration compare to preparing a similar solution from cesium hydroxide pellets?
The pre-dissolved 50% solution eliminates the exothermic heat generation and potential splattering hazards associated with dissolving solid cesium hydroxide. It also ensures consistent concentration without the variability introduced by manual dissolution processes.
5. What precautions should be taken when handling this solution?
Due to its extreme corrosivity, full PPE including nitrile gloves, safety goggles, and lab coat should be worn. All operations should be conducted in a properly ventilated fume hood, with neutralizers like dilute acetic acid readily available for spill containment.
