The unique and replaceable polyethylene (PE) Safe-Cone Filters act as a final barrier to prevent any fluids and liquid vapours from reaching the internal components of the pipette.
Standard Safe-Cone Filters are for general applications. They can be used for the same type of work as the Plus Filter is recommended for, but need to be changed more frequently.
Self-sealing Plus Safe-Cone Filters are meant for applications such as radioactive work, cell culture, bacterial and virological work and molecular biology.
The interval of changing the filter depends on the application and the sample. However, according to studies, the filter should be changed daily (or after 50 to 250 pipettings) and immediately in case of over-aspiration. To ensure safety of the user, forceps should be used to change the filter. The mLINE® pipettes also feature a built-in filter ejector. In addition, clean the tip cone with ethanol (70%) prior to assembling a new filter.
Protects the pipette and the sample from contamination
Prolongs the pipette’s lifetime
Reduces maintenance intervals
Is cost-effective

Excellent choice
I will skeptical when buying these because I have a pitbull bulldog that likes to chew holes in every toy. This is her favorite she choose on the ball, but she doesn’t actually ruin it because she can’t. It holds up one of the squeakers broke, but that’s expected I guess my wife actually ordered more. I’m not sure if it was from the same seller or not but those ones they don’t favor as much for some reason I seen the same different colors. My dog even sleeps with it sometimes. The picture shows for sleeping with it. I’m definitely happy. I got these. They are tough. I like the fact that they have those little recessed holes so they can grab a hold of it and not get it all slimy like the other balls we have.

Durable and a must have for aggressive chewers
Color: Blue+Red
These are without a doubt the best toys that I have ever purchased for my dog. He's an aggressive chewer and quickly destroys almost every toy I buy. This one hasn't been destroyed yet and the squeaker is still working at about 5 months.

GSD Winner
Color: Blue+Red
10/10 recommend for big dogs with a tough chew. Our GSD absolutely loves these squeaky balls. They have perfect texture for his teeth and for our grip. They are the size of a baseball and are so durable and fun. Yes the squeaky is LOUD but he loves them so much that it's cute

Great buy
Color: Blue+Red
My dogs kill every toy. They arrived very agressive chewers. These have lasted way longer than most balls have. Great value

If your dog loves tennis balls, you NEED these
Color: Azure+Orange, Color: Azure+Orange
Raising any puppy is tough. Raising a German Shepherd puppy has often left me questioning my life choices. So I was ecstatic the day that my 60-lb puppy decided that he loves tennis balls and occupied himself for 2 hours without needing constant intervention. Naturally, my immediate response was to make sure we had a constant supply of large tennis balls for dogs available. Now my puppy loves mischief, but he’s not an aggressive chewer. And I was irritated to discover that every brand and size of tennis ball broke within an hour max of play. By simply playing fetch and batting the ball around with his paws, every single tennis ball split into 2 halves. We needed something better! These squeaky balls are exactly that! They come in a 2-pack. I gave my pup the 1st one a week ago and it’s still going strong! We play fetch in the backyard, he brings it into the doggy pool with him, it rolls around in the dirt and can be rinsed off easily. It’s by far his favorite toy, and he takes it everywhere with him. Finally a squeaky ball that can keep up with my dog! These are the perfect size, texture, bounce, squeak, everything. These are the ONLY squeaky balls I will buy from now on. Five stars for sure!
