By WWII, scientists had already begun looking at alternative gelling substances for routine use in bacteriology, but concluded that agar was still better as it is both firmer and easier to handle. Today, some specialized microbiology applications use the colloid carrageenan (extracted from red seaweed Chondrus crispus, or “Irish Moss”), a more transparent and less auto-fluorescent alternative to agar (agar emits its own background fluorescence when excited by light). However, for routine bacteriological use, carrageenan is more difficult to dissolve, requires higher concentrations, can degrade at high temperatures, and forms weaker gels, which may result in puncturing its surface during the plating of cells.
在这个对价格极度敏感的区间里，不犯错就是最大的美德。

While the Arctis Nova 3 have great compatibility with all of your modern major gaming consoles, including PC and Switch 2, there are two versions, so you'll want to make sure you grab the right one for you. The Nova 3X supports all systems, including Xbox and PlayStation consoles, while the 3P lacks Xbox support. Unless you've committed to never buying Sony for some reason, I'd recommend going for the 3X, which are currently marked down to $90 in white. If you're a dedicated PlayStation gamer or want a splash of color, the Aqua Nova 3P are also available for a slightly higher $97 in Aqua or $100 in Lavender.
