Making the Difference — Supporting Science

Your work inspires us. We're thrilled to be designing and building pipettes and tips that have been integral to many important discoveries.

And since we know funding can sometimes be a challenge, we've started a new program to select one researcher each month to receive a free Rainin instrument for their research.


It's simple: Register below, and let us know which of our instruments you need — and above all, why.

At the end of the month we'll review submissions and pick a winner. We will announce it on this page and publish your winning entry. And we'll ship you the instrument you asked for.

What are you waiting for? Apply for a free Rainin instrument today.

Below is the collection of winners, whose research we decided to support. Feel free to read up on their research and get inspired to tell us about what you're working on.

We want to hear your stories and help you make an impact with your research.

Extracting and amplifying specialist species DNA

It's humid and dry at the same time. My legs are bleeding from walking steadfastedly through bramble, my dog obliviously nipping at my heels as I fight my way through thorns. Squishy ground that threatens to suck my shoes away from me but eventually I plug my way to a beautiful, quiet stream, where I finally see an abundance of smelly white flowers whose leaves are full to the brim with larvae. I bend down, ID the plant, and plop a confused larva into a tube of 100% ethanol.

I went to great lengths (literally and figuratively) to collect several thousand larval samples whose genetic information will tell me about the the evolution of host adaptation. I crossed up and down the length of California, fighting physical injury, exhaustion, and nosy (and for some reason unreasonably angry) bystanders. Now the only bottleneck is the speed at which I can genotype them. Lab work takes time. Each sample has to have its DNA extracted, and amplified, and run out on a gel. Nothing is more frustrating to me than the slow grind of pipetting 4 uL of DNA, adding it the loading dye. Adjust the pipette to 5 uL. Load the gel. Adjust to 4 uL. Next. Repeat 4,519 times, not including PCRs that, for reasons only known to the lab goblins, need to be re-run.

I want to know already. Why has a specialist species suddenly adapted to a totally new host plant? What is the species and host distribution of these mustard-feeding insects? When can I get out of the lab and back to the field? A Rainin multi-channel electronic pipette would help me process my thousands of samples more quickly and get me back into the field, doing what I love to finish my PhD.

A pipette to accommodate new spacing on BeadChip

In 2009, our team in Laboratory of Department of Animal Genetics started to work with new and fresh method of genotyping. We met the genomic microarrays. The beginnings were sometimes dificult. How to load 12- 14 microliters of DNA sample onto BeadChip section in short time if the number of these samples is 96 or more. But we learned more and more. So when we started to use the 8-channel pipettes the life has become easier and more pleasant. But in 2017 year the spacing of the BeadChips has change and we had to return to use a single channel pipette. But we found the information about the another kind of precision pipette eg. adjustable spacer multi-channel one. We would like so much to work with Rainin LA8-50XLS pipette (5-50ul).

Prepping culture media for lactic acid producers

I have been pursuing a PhD at the ICT Institute in Prague. My area of study is using waste materials such as straw hydrolysates or feathers to prepare beneficial and financially low-maintenance culture media for lactic acid bacteria to produce lactic acid, a substance used in a very wide industry. Of course, pipetting is essential during this research. The volumes are often small, where precision is imperative, and since all our students are in our lab (bachelors, diplomats, etc.), most of our pipettes are really in poor condition. Frequent repetitions are needed because the pipetted volume was not consistent with the requirement, etc. I think a new pipette from Rainin could greatly facilitate my research and move me a step closer to results that would be important not only for my final work, but also for future benefit to the chemical industry. That's why I think your Pipet-Lite LTS Pipette L-1000XLS + would be the right partner for me in my research.
