Non-sterile, gridded membrane filters can be used for colony counting, particle testing and microscopy. Before usage, the filters first need to be sterilized (e.g. by autoclaving at 121°C). The membrane filters are available in different pore sizes and three different material types. Cellulose nitrate filters (mixed cellulose ester) contain a mixture of cellulose nitrate and cellulose acetate, which assures effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal stability with very low adsorption characteristics. The various filter colors allow the best possible contrast to the colonies or particles for easy and reliable quantification and identification.

Super portable sunscreen
Size: 0.49 Ounce (Pack of 1)
These are awesome for keeping in a backpack, a kids sports bag, or just dropped in your pocket while traveling. I probably would want to use this as my primary sunscreen on the regular just due to size but it's amazing for reapplying during the day.

Great sunscreen!
Style: SPF 50 Stick, Size: 0.49 Ounce (Pack of 1)
Great sunscreen for babies/toddlers. It works well and it was a breeze to apply. It did take some effort to rub in. The product itself is very small, so it’s convenient to carry in your pocket or throw in a bag. But I’ve also misplaced it a few times.
