What purities is rubidium available in?
We offer rubidium in graded purities aligned with the differing requirements of research and development. Rubidium metal is available at a purity of 99.5+%, making it suitable for demanding applications where a high elemental content is critical. For rubidium salts, we cover a broad purity spectrum:
- Rubidium chloride, for example, is available in 98+%, 99% and 99.9%,
- Rubidium bromide also in 98+% and 99+%.
- Rubidium acetate is available at a purity of 99.9%,
- Rubidium carbonate in 99% and 99.9%.
Depending on your requirements—whether for synthesis purposes, analytical reference samples or specialised materials development—we can recommend the appropriate purity grade. We will be pleased to advise you on selecting the optimal quality for your specific application.
What forms of rubidium does ChemPUR offer?
Our rubidium range includes both the pure metal and a wide selection of compounds in various packaging formats. We supply rubidium metal in sealed ampoules as well as in so-called break-seal ampoules, which enable particularly simple and safe handling in the laboratory. In addition, we stock a wide range of inorganic rubidium salts in powder form, including:
- Chlorides,
- Bromides,
- Carbonates,
- Acetates,
- Nitrates,
- Sulfates,
- Molybdates
- and tungstates.
In addition, the range includes rubidium evaporation materials (Evaporation Materials) as well as ingots, which are primarily used in thin-film technology and materials science. The products are offered in practical pack sizes—from small research quantities through to larger containers for development needs. Please contact us if you require a specific form or packaging format.
Why is ChemPUR the right contact for rubidium?
As a fine chemicals distributor with many years of experience in specialty metals and inorganic compounds, we have the necessary know-how to supply reliably even when dealing with reactive and safety-critical elements such as rubidium. Our range includes the metal itself as well as an extensive selection of rubidium compounds in various purity grades and pack sizes—tailored to the needs of research institutions, development departments and technical buyers.
We place particular emphasis on careful quality control and transparent product labelling, so you always know which purity and molecular weight the ordered product is based on. In practice, this means: shorter procurement routes, reliable availability and competent advice from a single source. We will be pleased to assist you personally with enquiries regarding quantities, purities or special terms.
What applications is rubidium used for?
Rubidium is an alkali metal in period 5 with a range of interesting physical and chemical properties that make it attractive for various scientific and technical applications. In basic research, for example, rubidium is used in atomic physics, including in the development of atomic clocks and in laser-cooling experiments. Rubidium compounds are used in the glass industry as well as in the production of specialty glasses and ceramics.
In the electronics industry, rubidium salts are used as starting materials for functional layers and coating processes. Rubidium is also being investigated in research on photovoltaic systems and in medical imaging. For your application, the relevant factors are the respective chemical form—whether metal, halide or oxosalt—as well as the required purity. We will be pleased to support you in selecting the right product for your research project.
Which rubidium compounds are available?
Our range of rubidium compounds is broad and covers the key substance classes in demand for research and development. In the area of halides, we stock rubidium chloride and rubidium bromide in several purity grades. In addition, rubidium carbonate and rubidium acetate are available, which are used as starting compounds for syntheses as well as doping agents.
In addition, our product catalogue includes rubidium nitrates, rubidium sulfates, rubidium molybdates and rubidium tungstates—substances that are relevant, among other things, in materials research, catalysis and coating technology. We also offer rubidium as an evaporation material for PVD processes. Various pack sizes are available depending on requirements. For products where the price is stated as price on request (POR), we will be pleased to provide you with an individual quotation—simply contact us.
How is rubidium delivered and stored safely?
Due to its pronounced reactivity, rubidium metal is one of the particularly safety-critical materials: it ignites in air and reacts explosively with water, which is why it must be handled and stored under a protective atmosphere. We therefore supply the metal exclusively in sealed ampoules or break-seal ampoules, which ensure safe handling until actual use.
As dangerous goods, transport is subject to special regulations—an additional dangerous goods freight surcharge applies for these products, the amount of which we will inform you of on request. For rubidium compounds in salt form, less stringent requirements generally apply; however, we also recommend dry, well-ventilated storage in accordance with the respective safety data sheets. Please contact us before ordering so that we can clarify the appropriate shipping option for your situation together.
Does ChemPUR also support product selection?
Selecting the right rubidium compound depends on several factors—including the desired chemical form, the required purity, compatibility with the respective process, and quantity considerations. We will be pleased to help you identify the right product from our range. For products that do not have a fixed list price but are offered on a price-on-request (POR) basis, we will readily provide you with an individual quotation.
In addition, we can advise on questions regarding the safe handling of rubidium metal, suitable solvents for specific compounds, or alternative compound classes. Furthermore, if required, we can point out extended product categories or special quantities that are not listed in the standard range. Contact our specialist team—we will work with you to find the optimal solution for your research or development needs.
