Witeg Cryo cube box (PP) 81 places for 4.5 ML cryo vials, CryoBox Vial Rack (Pack of 1) || Cyrobox ||

They were only utilized at 4 degrees Celsius, but they will soon be used in the freezer. These are the best boxes I've tried thus far. Unlike other boxes that open up when using 2ml cryo-tubes, this one closes firmly!When I eventually need to expand my Lab ,I plan to purchase more of these. The quality of the box is excellent.

I have been constantly happy with Witeg's products, and this is my fifth purchase from them.The vial racks were wrapped in plastic bags and came clean. The trays were easy to open, and the polycarbonate substance is quite good. They have worked flawlessly for sorting ink samples, however I haven't yet tried them in a cryostorage environment. It's important to note that these racks are substantially less expensive than Other Brands, which would cost almost four times as much.
