Product Description :
A beaker is a generally cylindrical container with a flat bottom to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one millilitre up to several litres.
FEP beaker, also known as perfluoroethylene propylene beaker: it has excellent chemical resistance, and can withstand almost all chemical solvents. Suitable for preservation of chemicals and samples, or general high-temperature and high-pressure sterilization. With flanging design, it can be easily clamped and moved. It can dissipate heat and increase mechanical strength. There is a mouth at the edge, which is convenient for pouring liquid. Product characteristics: 1. High and low temperature resistance: service temperature can reach - 200~+205 â?? 2. It can be used with ICP-MS/OES/AAS and other instruments, and is one of the necessary products for ultra purification laboratory 3. Extraordinary chemical resistance, can withstand almost all chemical solvents (aqua regia, hydrofluoric acid, etc.) 4. Extremely low dissolution and precipitation, it is an excellent vessel for storing reference materials, highly corrosive, expensive and high-purity reagents.

Tris saturated phenol: 1. Take out the re steamed phenol from the refrigerator and place it in a 68 water bath at room temperature to dissolve it. Do not put it in a 68 â?? water bath immediately to prevent the glass from cracking; 2. Add 8-hydroxyquinoline to 0.1% and �² - mercaptoethanol to 0.2% (stock solution 14.4mol/ml), mix well, the solution turns yellow, and pour into the separating funnel (it can also be carried out in a beaker); 3. Add 1mol / ml tris (ph8.0) of the same solvent, mix it repeatedly, and let it stand still until it is layered; release the Yellow phenol solution in the lower layer and discard the upper layer; 4. Add solid Tris about 1g / 100ml phenol, shake well and remove the aqueous phase; 5. Add 0.1mol/mltris (ph8.0) to balance several times until pH is 8.0; 6. Add 0.1mol/mltris (ph8.0) and store in brown bottle for 4 degrees; 7. If yellow disappears or pink, it cannot be used. Tris saturated phenol is toxic and has a strong irritant effect on skin and human body, so it needs to be operated in the fume hood. Avoid harm, safety first.
