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.

DON’T WASTE YOUR MONEY-it is CRAP!!!
Color: Blue Green Orange
What a Piece of Garbage! If I could I’d have given this ZERO STARS!!! My Dogs WON’T GET NEAR IT! Obviously it smells wrong or they sense that it is TRASH!! If I were a canine, I wouldn’t give it my consideration Either! It looks large online but when you receive it, it is a Small RAG! THIS Attempt at a SNUFFLE MAT IS INSULTING!!! DON’T WASTE YOUR MONEY on this GARBAGE‼️During the time period I had to return it, I was in the Hospital after having a Heart Attack!!I am still trying to Recover & I CANNOT DO MUCH!! Otherwise I would have returned it!!! It’s sitting in a corner in my bedroom. I had to unwrap the CHEAP PLASTIC WRAP COVER so I could even tell WHATit was. As It was diagonally Rolled UP, I had to unwrap & look at it & show it to my Dogs-The DOGS WOULDN’t get near it & now I’m STUCK WITH THIS PIECE OF GARBAGE THAT I CANNOT GET MY MONEY BACK ON‼️Yes, I am upset ! This ugly Thing hasn’t even been TOUCHED by my 3 Dogs & now I’m STUCK WITH SOMETHING USELESS THAT MY DOGS WOULDN’t even get near & I CAN’T GET A REFUND FOR!!! THIS IS THE TYPE OF TRANSACTION THAT I FIND HIGHLY OFFENSIVE ABOUT AMAZON & the Fly By Night companies they represent!!!!!

Nice but…
Color: Blue Green Orange
Nice but not very sturdy and it comes rolled up so it’s difficult to get it to lay down for your dog.

Both my dogs LOVE find the treat game time!
Color: Orange Red Blue, Color: Orange Red Blue
Both my dogs have loved this for years. Both senior dogs - great fun activity for them and they really hunt for all the treats we hide! My little one usually wins and takes over the game board then uses it as a lounger after :-) It’s very interactive with different ways to hide treats and challenge the dogs.
We’ve had it awhile and it has stood up to many uses and washes. Very easy to store and simply roll out when it’s game time. Highly recommend!

Perfect for snuffle dogs
Color: Blue Green Orange
If your pup/dog snuffles EVERYTHING or has a demanding intellectual stimulation food regime they set themselves this is for you! I have to roll out the mat above the floor to situation treats, but once it hits the floor my puppy is preoccupied for hours. She has so much fun sniffing through every element to find her treats. While the mat is easy to use I recommend rolling it back up immediately once most treats have been found to avoid chewing on the actual mat pieces (this could present a durability issue as the fabric is chewable). I use different flavored and textured treats throughout the mat as well as her normal dog food to keep her interested. Definitely worth the money if you have a snufflopogus puppy like I do.
