盐水溶液是指盐溶液,您可以使用现成的材料自行准备。该溶液可用作消毒剂,无菌冲洗液或用于实验室工作。该配方是正常的盐溶液,这意味着它与体液的浓度相同或等渗。盐溶液中的盐阻止细菌生长,同时冲洗掉污染物。由于盐的成分与人体的盐成分相似,因此与纯水相比,造成的组织损伤更少。从技术上讲,只要您将任何盐与水混合,就会产生盐溶液。然而,最简单的盐水溶液由氯化钠(食盐)在水中组成。出于某些目的,使用新鲜混合的溶液是很好的。在其他情况下,您需要对解决方案进行消毒。混合解决方案时,请牢记这一目标。例如,如果您只是用盐溶液冲洗口腔作为牙齿冲洗液,您可以将任意量的食盐与温水混合并称之为好。但是,如果您正在清洁伤口或想要将盐溶液用于眼睛,那么使用纯净成分并保持无菌条件非常重要。您可以将无菌溶液分配到无菌容器中。通过煮沸或通过消毒溶液(例如出售用于家庭酿造或酿造葡萄酒的类型)对容器进行消毒来对容器进行消毒。最好用日期标记容器,如果在几天内没有使用该解决方案,则丢弃它。该解决方案可用于治疗新的穿孔或用于伤口护理。避免污染液体非常重要,因此理想情况下,一次制作尽可能多的溶液,让其冷却,并丢弃剩余的液体。无菌溶液在密封容器中保持适合实验室使用数天,但一旦打开,您应该会受到一定程度的污染。盐:您可以使用杂货店的盐。最好使用不加碘的非碘盐。避免使用岩盐或海盐,因为添加的化学物质可能会出于某些目的而出现问题。水:在普通自来水上使用蒸馏水或反渗透净化水。你想要每升水9克盐或每杯(8液量盎司)水1茶匙盐。虽然它是适当的盐度,但这种解决方案不适合隐形眼镜。商用隐形眼镜溶液含有有助于保护眼睛的缓冲液,此外,该溶液还含有可帮助保持液体无菌的药剂。虽然自制的无菌生理盐水可以用来冲洗镜片,但除非您熟悉无菌技术并使用实验室级化学品,否则它不是一个可行的选择。作为漱口水,您可以简单地将盐溶解在非常温暖的水中。你甚至可以加一茶匙小苏打(碳酸氢钠)。对于无菌溶液,将盐溶解在沸水中。通过在容器上盖上盖子使溶液保持无菌,以便在溶液冷却时没有微生物进入液体或空气空间。

新西兰梅西大学化学Assignment代写:如何制作盐溶液

Saline solution refers to a salt solution, which you can prepare yourself using readily available materials. The solution can be used as a disinfectant, sterile rinse, or for lab work. This recipe is a salt solution that is normal, which means it is the same concentration or isotonic to body fluids. The salt in saline solution discourages bacterial growth while rinsing away contaminants. Because the salt composition is similar to that of the body, it causes less tissue damage than you would get from pure water. Technically, a saline solution results whenever you mix any salt with water. However, the easiest saline solution consists of sodium chloride (table salt) in water. For some purposes, it’s fine to use freshly mixed solution. In other cases, you’ll want to sterilize the solution. Keep the purpose in mind when you mix the solution. If for example, you are simply rinsing your mouth with saline solution as a dental rinse, you can mix any amount of table salt with warm water and call it good. If, however, you are cleaning a wound or want to use the saline solution for your eyes, it’s important to use pure ingredients and maintain sterile conditions. You can dispense the sterile solution into sterile containers. Sterilize containers either by boiling them or by treating them with a disinfecting solution, such as the type sold for home brewing or making wine. It’s a good idea to label the container with the date and to discard it if the solution is not used within a few days. This solution could be used for treating new piercings or for wound care. It’s important to avoid contaminating the liquid, so ideally make just as much solution as you need at a time, allow it to cool, and discard leftover liquid. The sterile solution will remain suitable for lab use for several days in its sealed container, but you should expect some degree of contamination once it is opened. Salt: You can use salt from the grocery store. It’s best to use non-iodized salt, which does not have iodine added to it. Avoid using rock salt or sea salt, since the added chemicals may cause problems for some purposes. Water: Use distilled water or reverse osmosis purified water over ordinary tap water. You want 9 grams of salt per liter of water or 1 teaspoon of salt per cup (8 fluid ounces) of water. Although it is the proper salinity, this solution is not suitable for contact lenses. Commercial contact lens solution contains buffers that help protect your eyes, plus the solution includes agents to help keep the liquid sterile. Although homemade sterile saline could work to rinse lenses in a pinch, it is not a viable option unless you are familiar with aseptic techniques and use lab-grade chemicals. As a mouth rinse, you can simply dissolve the salt into very warm water. You may even wish to add a teaspoon of baking soda (sodium bicarbonate). For a sterile solution, dissolve the salt in boiling water. Keep the solution sterile by placing a lid on the container so that no microorganisms get into the liquid or airspace as the solution cools.
