1000 µL, Long Tip, Graduated, "ECO PACK" Refill Stack, Sterilized "123R-757CS" - (96 tips x 5 plates x 5 stacks)

These are great replacements for my plastic squeeze pipettes. I use pipettes for my brix refractometer. These are perfect for adding liquid for measuring or for adding flavorings to test samples. These do require a dial pump. since they are reusable, and you get sooo many. This box should last for several years.

Another home run from this company. Excellent deal for the quality and sheer magnificence in manufacturing standards. The apex of laboratory essentials. I cannot recommend more.

Love how compact this package is, and how you can easily take out a tray of tips to a work station, or hand out trays to multiple workers or students. seals nice to my pipette, and hydrophobic qualities are also great! Love the long ones for getting down into deeper centrifuge tubes and test tubes.

How I Use It:So I’ve been using these Watson pipette tips for two months mainly for my small business.Features that stood out to me:The tips work great, and I also really liked the autoclavable feature because it simplifies my day a lot. The amount of them in the box was pretty good too, I tend to get more work done.My Personal Experience:If I compare this one against the others I’ve used, this one is just plain better. I wasn’t expecting to like the fitment onto my pipette and accuracy as much as I did.Pros and Cons:What was good: very convenient.What was not: perhaps a bit pricey for what they are.Durability:After two months, it still does its job the first time every time with no fuss. I can’t really ask for more.Final Thoughts:Overall this is best for DIY tinkerer types. It’s been good for me and my needs and I’d buy it again.

I’ve been using these pipette tips regularly in my lab work, and they deliver consistent performance every time. The tips fit securely on my pipettes without any wobbling or leaking, which helps maintain accuracy during experiments. I appreciate that the natural color makes it easy to see liquids clearly, reducing the chance of errors.The packaging is practical, with the refill plate keeping the tips organized and easy to access. Being autoclavable is a huge plus, allowing me to sterilize them without worry and maintain a clean work environment. The tips also fit a variety of standard pipettes I use, which adds to their versatility.So far, I haven’t experienced any clogging or breakage during use, and they feel durable enough for repeated handling throughout busy lab sessions. Overall, these tips help keep my pipetting tasks precise and hassle-free.

These are pretty much as promised. They came well packed and neatly stacked in their box. They fit properly and pop off with no issue when they're supposed to. Overall, a nice pickup if you already have a rack and just need lots of refills.

While I got these for use with a pipette from the same manufacturer, they seem like standard generic pipette tips. They attached well and came off easily. I didn't have any problem with leaks or anything. It seemed like there was a tiny amount of plastic flash from the manufacturing, but it didn't seem to cause any problem; I was able to get every drop out of them without issue.
