Description
CAS number: 71-36-3
Chemical Formula: CH₃(CH₂)₃OH
Molar Mass: 74.12 g/mol
Synonyms: Butan-1-ol, n-Butyl alcohol, BuOH
With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in “gradient grade” as well as “isocratic grade”. This enables to minimize the gradient effect of the solvent involved. Filtered by 0.2 µm filter

1X and 10X TBE buffer (Tris-Borate-EDTA), Biobasic
Login to see pricesBrand:
Bio Basic
Description
This product is currently not available. Please contact us for more information.
TBE buffer (Tris-Borate-EDTA, Biobasic) is commonly used in all DNA electrophoresis applications (both for acrylamide and for agarose gels). In general, TBE buffer offers better resolution of 0.1 to 3 kb fragments; whereas, TAE (Tris-Acetate-EDTA) buffer provides better resolution of fragments greater than 4 kb. Furthermore, TBE is better suited for high-voltage (>150V) electrophoresis because of its higher buffering capacity and lower conductivity than TAE. BIO BASIC INC. offers TBE in a number of different formats. 10X TBE liquid concentrate can be used to easily prepare a 1X TBE working solution by diluting with distilled, deionized water. 10X TBE Powder allows for the stable storage of the pre-mixed powder form that can be dissolved in distilled, deionized water to yield 1 liter each of 10X TBE buffer solution.
How to prepare a 10X TBE Buffer?
10X TBE buffer preparation is easy. Simply mix 10X TBE powder (SKU: A00269-500ml/A0026-4L) with an appropriate volume of distilled/deionized water. The 10X TBE buffer is ready to use now.
