Biotix xTIP4 Pipette Tips for Rainin LTS Pipettes by Biotix

"These are great when compared to higher priced competition, work well with all of our laboratory applications."

"I like them! Fit easily into my Rainin LTS models, easy to dispense and hold volume well. No issue with packaging (easy to stack, environmentally conscious). I know it is no easy change but possibly include biohazard bag to ship dirty tips back to Biotix for recycling. It also brings up contamination issues but plastics are number one source of waste for labs. I know this won't change overnight but just throwing out ideas to companies that use plastic the most. thanks for the free sample ! Vincent Moschea did a great job shipping me my free sample. Although we just shut down our lab a few months ago, I will keep an eye out for any way to incorporate Biotix pipette tips in the future"

"High quality tips and great price for the money. Sturdy design, not flimsy at all."

"These tips are a good replacement for the Ranin LTE tips. The only problem I have with them is that the 250 uL tips don't sit flat in their rack, so picking them up with a multi-channel pipet is pretty annoying."

"The tips filtered tips are just as easy to use as the rainin tips. The only thing the Rainin tips win at, is the ease one can unpack and open the tip boxes (unwrapping the plastic on them) other than that, they are equally as good."

"Tips are good quality, sharp tip. The rack holder is a little light, not stable enough. With the refill stack, the tips sometimes don't fit well."

"Biotix tips are amazing. They are way better than the cheap VWR tips, which I find leak constantly, especially at lower volumes. The filtered, low retention tips are amazing for any type on small volume pipetting. It also works really well for PCR processes, which needs very accurate pipetting. The tip box is also really useful for storage of tips, and misc. lab items."

"Pipet tips are accurate, results are reproducible. Excellent packaging, easy to use."

"The tips work great. They don't need to be pushed strongly into the pipette to get a good seal and eject easily. They have low liquid retention which makes them great for pipetting highly viscous compounds."

"They are great pipette tips. Consistent and never had any issues. Box is a bit flimsy but that's all."

"I got Biotix filtered pipette tips about a week ago and I am testing their quality. The pipette tips are easy to use and work good with TLS Rainin pipettes. I had a great experience with the vendor, I requested a sample and I got them three days later."

"The tips work very well form day to day use. They do not require a lot of force to apply to the pipet nor to eject. The tips are all-around a good deal."

"Good quality product. The tips are easy to use. Easy ejection. The results are reproducible. One piece of advice would be is if you push down to hard on to the pipet box, you will bring it back up with you when you try to take out the pipet. The box is also fairly easy to tip over. Ordering has been an issue as well."

"High Quality results and very easy to use!! I love the stacks that make it easy to refill the racks."

"Good quality and fit the Pipette well. It has sharp tip which makes the accuracy of it."

"Easy to use. Residual liquid is not left in tip. Accurate pipetting."

"The pipet tips are nice because they are flexible and fit comfortably on the Rainin pipets."

"These tips seem to perform the same as the OEMs tips. I haven't had any issues with them so far."

"Tips were easy to use and fit our Ranin pipettes well. Tip box felt a bit flimsy."

"The tips works really well and come at a great price. The reload is great but I would like to have a better cover than the small one that barely covers the box. Makes the storage of started trays difficult. Talking about covers, the one for the single boxes needs to be more steady. We lost some boxes because of the slipping covers. As for the bottom part, it's great but maybe it's too light because sometimes the bottom come with a tips and tumble (particularly with the green boxes). I've also had struggle with the 20 ul tips with a rainin multichanel. Seems like the sealing isn't sufficient, I have variations in volumes between the channel. I need to push each tip manually, which is a big waste of time."

"We tried this series when we performed protein samples. We used this line to extract protein which uses lysis buffer containing detergent. Once this lysis buffer is mixed with protein samples, it makes a viscous solution. Usually, I saw some sample left on the inside of the tip but I did not see any sample left when I used this Biotix low retention tip series. I used unfiltered tip since I did not see the necessity of using filtered tip for my protein work. This unfiltered low retention tip series is quite cost effective since it has a similar quality with resin treated expensive tips."

"This product is very affordable and easy to handle. Very low to no retention. It comes in sterile packs so you are good to go with your work when you need it."

"We evaluated the xTip for Rainin (10uL and 250uL). They are easier to put on the pipet, eject more smoothly, and retain less liquid than Rainin brand tips. Great, but a bit pricey!"

"Pipette tips aren't usually something to get excited about...that is until I used the new Biotix X-Tip. After a cross-comparison between other tips--I found Biotix to be highly effective, precise, and accurate. Amazingly low retention compared to other leading tips. Fearing sounding like an infomercial--I should just say that these tips are pretty awesome and leave it at that."
