Sodium Hydroxide Of the cleaning agents, sodium hydroxide (NaOH), otherwise known as caustic soda, is widely used in breweries worldwide. 0000005472 00000 n When sodium hydroxide used for sanitization of chromatography media, the ability to withstand stringent sanitizing conditions depends on the following factors. This eventually turns the body into a liquid with coffee-like appearance and the only solid that remains are bone hulls, which could be crushed between one's fingertips. 0000002540 00000 n 0000010746 00000 n Even without the heating, high concentrations of sodium hydroxide require facility and equipment evaluation and use of safety equipment to protect workers. �K��R����Br�@�g���=��:b;&���b>���#��OG�3��'�Q�W�����FLj���c�ܼ#��-�HѐF�����=]��K'Y���ˤ��w�pi����O/�ř���Kp:a.m]�C9�dQ���g����*s.L;X�����Xׇ�l4{��8��݄�(f�X;��u�>���e. with petroleum distillates and cresols Sodium hydroxide, mixt.

Remember Me 0000007132 00000 n As with any sanitizing agent, certain precautions should be taken and compatibility with both It can also be dangerous for staff and animals if it is improperly handled or not adequately rinsed after use. Once evaluating a new cleaning agent for a resin, make sure it is compatible with system components as well. with sodium borohydride Sodium hydroxide, mixt. 0000014915 00000 n Do not spill solids on the balance. 0000012770 00000 n �"pt�ux�~��+��+�z�E�p?�T�+���+����2��.t�3�e�&Ԗ�=�B���� +�����u��G��{���&�h����� Before handling, correctly calculate the amount needed (~16 g). It is also a common ingredient in oven cleaners. It is common practice in industrial manufacturing to save time by adding a salt, such as sodium chloride, to the sodium hydroxide solution to combine cleaning with sanitization. Endotoxins are effectively removed by using sodium hydroxide sanitizing agent. 1. 0000009629 00000 n I agree to the 0000024907 00000 n 0.1 M sodium hydroxide was sufficient to inactivate the murine leukemia virus, a commonly used model enveloped virus (6). 3. For resins, the foremost cleaning agent is sodium hydroxide. Sodium hydroxide may not completely eliminate bacterial spores alone in further good manufacturing process required to complete the process. Caustic soda, Lye [Sodium hydroxide], Soda lye, Sodium hydrate Colorless to white, odorless solid (flakes, beads, granular form). 2. As a cleaning agent, sodium hydroxide saponifies fats and dissolves proteins. Consequences of chromatography column contamination include, Sodium hydroxide has been used extensively to get rid of proteins from ion exchange, hydrophobic interaction, and gel filtration media. 0000005679 00000 n 0000007154 00000 n The advantages of sodium hydroxide as a cleaning and sanitation agent are, Sodium hydroxide has been shown to be effective in removing proteins and nucleic acids. It is a powerful detergent and is used to suspend protein and to convert fats to soap, and it is cheap. with ammonia Sodium hydroxide, mixt. 0000011742 00000 n 0000009650 00000 n 0000004474 00000 n 0000011763 00000 n Since it is a bacteriostat it is recommended for the removal of bacteria from chromatography equipment sodium hydroxide should be added along with ethanol. It is also a common ingredient in oven cleaners. 0000005708 00000 n 0000001775 00000 n Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called "caustic". 0000014837 00000 n Chromatography columns can become contaminated by a variety of protein and nonprotein species during a purification process. 1 M sodium hydroxide and 3 M sodium chloride, with a total contact time of one hour, effectively removes radiolabelled calf thymus DNA from a weak anion exchanger. A higher concentration of sodium hydroxide may be required if lipids are bound to a protein. During restrictive inspections, producers of biopharmaceuticals and biological products usually give attention to cleaning and cleaning validation of chromatography resins and multiuse purification systems. 0000001277 00000 n 0000013773 00000 n 3. terms and conditions. Surfactants can be added to the sodium hydroxide solution in order to stabilize dissolved substances and thus prevent redeposition. Sodium hydroxide is widely accepted for cleaning, sanitizing and storing chromatography media and systems. A sodium hydroxide soak solution is used as a powerful degreaser on stainless steel and glass bakeware. 0000024829 00000 n What Is Sodium Hydroxide? 0000014631 00000 n Sodium hydroxide is a kind of strong base, and used to make electrolyte. �h���2�,���[5��4��¾\ ��6�}�Y��N�Y�K;�����gn��V^���$b�i��`����'`��j�Xj@;|�}K�T�6��\ ����@4ܼ��T?� ]�>A�li��}\(�2�]��{�o�'�Ei{��4��\n���ǥ\n\(����) /FontFile3 85 0 R >> endobj 56 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 181 /Widths [ 278 333 556 556 556 1000 944 278 333 333 556 556 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 556 556 556 444 800 721 611 722 778 611 557 778 834 332 389 722 611 1000 833 833 556 833 722 500 666 722 723 1000 778 722 722 333 278 333 556 500 278 500 556 444 556 444 333 500 556 278 278 556 278 832 556 556 556 556 389 389 333 556 500 778 556 500 444 333 222 333 556 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 278 0 0 0 500 0 0 990 0 0 0 0 0 0 278 0 556 556 0 0 0 0 0 800 0 0 0 333 0 0 400 556 0 0 0 556 ] /Encoding /WinAnsiEncoding /BaseFont /EDJANA+Sabon-Roman /FontDescriptor 55 0 R >> endobj 57 0 obj /DeviceRGB endobj 58 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 181 /Widths [ 278 222 333 556 556 889 667 222 333 333 500 600 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 600 600 600 389 800 611 667 611 667 556 556 667 722 278 444 611 500 833 722 667 611 667 667 556 556 722 556 833 556 556 556 333 278 333 600 500 222 500 556 500 556 500 278 500 556 222 222 500 222 833 556 500 556 556 333 444 278 556 444 667 444 444 444 333 222 333 600 500 500 500 0 0 0 0 0 0 0 0 0 0 0 500 500 500 500 0 0 0 0 500 0 0 0 0 0 0 0 500 500 0 278 0 556 556 0 0 0 0 0 800 0 0 0 333 0 0 0 600 0 0 0 556 ] /Encoding /WinAnsiEncoding /BaseFont /TradeGothic-Light /FontDescriptor 61 0 R >> endobj 59 0 obj << /Type /FontDescriptor /Ascent 722 /CapHeight 722 /Descent -192 /Flags 262176 /FontBBox [ -167 -228 1000 971 ] /FontName /TradeGothic-Bold /ItalicAngle 0 /StemV 126 /XHeight 544 >> endobj 60 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 181 /Widths [ 278 278 333 556 556 889 667 222 333 333 500 600 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 600 600 600 444 800 556 556 556 556 500 444 556 611 278 333 556 444 778 611 556 556 556 556 556 500 611 556 833 556 556 500 333 278 333 600 500 278 500 500 500 500 500 278 500 500 278 278 500 278 722 500 500 500 500 333 444 278 500 444 667 444 444 444 333 222 333 600 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 278 556 556 278 278 278 278 278 800 278 278 278 278 278 278 278 600 278 278 278 500 ] /Encoding /WinAnsiEncoding /BaseFont /TradeGothic-Bold /FontDescriptor 59 0 R >> endobj 61 0 obj << /Type /FontDescriptor /Ascent 722 /CapHeight 722 /Descent -184 /Flags 32 /FontBBox [ -167 -212 1000 949 ] /FontName /TradeGothic-Light /ItalicAngle 0 /StemV 60 /XHeight 520 >> endobj 62 0 obj /DeviceGray endobj 63 0 obj [ /Separation /All /DeviceCMYK 86 0 R ] endobj 64 0 obj /DeviceCMYK endobj 65 0 obj [ /ICCBased 87 0 R ] endobj 66 0 obj 1198 endobj 67 0 obj << /Filter /FlateDecode /Length 66 0 R >> stream
