It’s also worth noting that even if alternatives superior to agar were found, scientists are reluctant to abandon established protocols (even when microbiologists do use other jellies, they often still add agar to the mix, for example, to increase the gel strength of the solid media). As agar has been the standard gelling agent in microbiology for around 150 years, an enormous infrastructure of standardized methods, reference values, and quality control procedures has emerged around its specific properties. Switching to a different medium (even a superior one) means results may not be directly comparable to decades of published literature or to other laboratories’ findings.
Fujifilm’s $116.99 Instax Mini 41 is the long-awaited follow-up to the Mini 40. The updated model retains the retro design found on the prior model but introduces parallax correction, a feature borrowed from the Instax Mini 12 to help users avoid off-center shots when taking close-ups. It didn’t take long testing the Mini 41 for me to realize it’s simply the Mini 12 for adults. With its black-and-silver body and flatter, squarer edges, the Mini 41 looks sleeker and more stylish.
