法规信息
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
Who do I contact about larger solvent volume needs?
Email us at labessentials@sial.com or visit Sigma-Aldrich Fine Chemicals for development and manufacturing-scale inquiries: safcglobal@sial.com
How do I know what packaging options are available for a solvent?
The Solvent Center gives you the ability to review all the specifications associated with our solvent packaging. This includes physical dimensions, closure types, dispensing methods, UN/DOT Rating as well as solvent compatibility. Visit the Solvent Center.
Who do I contact if I need a solvent blend, which you do not carry?
Email us at labessentials@sial.com. For a complete listing of all our Solvent blends, Visit the Solvent Center
The dispensing of solvents provides some challenges due to the number of container options available. What dispensing options are available for each container?
The Sigma-Aldrich Solvent Center provides numerous dispensing options for each container type. For a complete listing of all our dispensing options, Visit the Solvent Center.
Which solvent grade should I be using for my application?
Sigma-Aldrich Solvent Applications Table gives a guideline to common applications and the appropriate solvent grades. Visit: Solvents
What are the options for drying solvents?
Sigma-Aldrich offers a full range of high-purity solvents with extremely low water levels specifically manufactured for moisture sensitive Organic and Biotech applications. Sigma-Aldrich also carries various drying agents such as molecular sieves, which are typically compatible with organic solvents.
What apparatus do you recommend for HPLC solvent filtration?
The Sigma-Aldrich Vacuum Filtration Assembly gives you all the components you need including: funnel top, fritted glass funnel support, filtration flask, aluminum clamp, and silicone stopper. The Acrodisc Syringe Filters offer high quality filtration for analytical samples, certified for HPLC to ensure low extractable and available in a broad range of membranes to meet sample compatibility requirements.
Can you recommend a Solvent Extractor for organics from aqueous solution?
Solvent extractors are often used for the quantitative extraction of organics from aqueous solutions and separations in immunoassays. The MIXXOR system has been applied successfully in many laboratory solvent extraction operations and is ideal for the rapid screening of alternative solvents for specific extraction problems.
Why do peroxides form in certain solvents and how do I test for it?
A significant number of laboratory solvents can undergo autoxidation under normal storage conditions to form unstable and potentially dangerous peroxide by-products. Molecular structure is the primary factor relating to a material’s potential for hazardous peroxide formation. It is important to understand the stability of materials in use and if unclear, consult Sigma-Aldrich Technical Support, techserv@sial.com
What are some of the preservatives used in the most common ethers and chlorinated solvents and why are they added?
Certain solvents will degrade over time requiring special handling and storage considerations. In addition, the products of certain degradation processes pose a potential safety risk if present at sufficiently high levels. For these types of materials, small amounts of stabilizing chemicals are added to slow down or stop material degradation.
