A&D BM-252 - 250g x 0.00001g Semi-Micro Balance
A&D BM-252 confidently handles even trace quantities of valuable or degradable substances. Critical to precision weighing is static control, which is why the direct current fanless ionizer is standard on all models.
Sample weighing is at the centre of many laboratory processes, and the A&D Ion Series provides the performance, and features, standard accessories to bring real convenience and efficiency to your lab. Automatic response adjustment function uses environmental data from built-in sensors, to compensate for the balance’s characteristics to deliver fast and stable results.
Calibration is also automated and always available with a single keypress. A range of accessories adds extra convenience.
BM-252 semi-micro balance has the performance and standard accessories to simplify microgram measurements. The Ion Series now makes microgram ( µg ) measurements accessible to all researchers and offers a real choice in microbalances.

Suits turned yellow
Purchased for a 2 week sun vacation. I have used this product before and have been very happy with it.
However, this item turned our shirts and suits yellow!
It smells great and prevented sunburn - but everything is now yellow. :(

Worked great
Style: SPF 30, Size: 3 Ounce (Pack of 1)
My skin is very sensitive to the sun. My skin does not tan I sun burn quickly! I love this sunblock because according to the ingredients it's reef & sea animal friendly. I found this product didn't leave a very noticeable white cast on my skin. I was able to blend it with very little noticeable white cast. I didn't find it sticky or really rubbing off on my clothes or bathing suite. In respect to all the things I mention it was all at a very minimal notice. For me it didn't have a smell of any kind. I used this product on vacation in Mexico. I tried & stayed out of the sun as much as I could. I went on a Mayan ruin tour following a snorkeling excursion & did not get a sunburn! Usually for that long period of time in the sun I would have received a light sunburn using other sunblocks but instead I actually got a light tan! I did apply this product on my body & face. I have to say this is my 1st time using this brand & it worked super well for me. :) *Just FYI when I applied this product I didn't need to apply to much if you do its going to obviously leave a white cast. I only applied as needed through out the day. Also make sure you give it time to sit to soak into your skin before putting on your clothes. After all you do have to wait a few min after applying before going out in the sun. That's any sunblock directions.

Finally! A sunscreen that works and does not burn my eyes.
Style: SPF 30, Size: 3 Ounce (Pack of 1)
I am unable to use chemical or hybrid sunscreens on my face because they "melt" and destroy my eyes. Living in the south means daily sunscreen year-around is a must - having found this product is a godsend. Unscented, no chemicals to discolor my clothes, no titanium dioxide so no purple-white ghostly cast, easily rubs in. Simply perfect!!!
