Precise nanoliter-volume injections with intuitive SMARTouch™ controller
NANOLITER2020 is the complete system. 300704 is the NANOLITER2020 Injector Head only, and the controller and the accessories are not included.
- Perform nanoliter volume injections using glass micropipettes
- Nanoliter Injector works on the principle of Positive Displacement. An internal micrometer step motor precisely moves the metal plunger which pushes the oil inside the micropipette, and the oil-layer pushes nanoliter volumes of aqueous sample out of the pipette tip.
- Fine control of plunger displacement along with proper sealing among gasket, glass micropipette, and oil ensures precision and accuracy
- NANOLITER2020 System includes the 300704 NANOLITER Injector, the MICRO2T SMARTouch™ Controller and many necessary accessories (See Details)
Make Your Microinjection with Nanoliter Precision
Simple-to-Use Touchscreen Controller
NANOLITER2020 is the updated version of WPI’s popular NANOLITER2010 Injector that is capable of performing precision injections in the nanoliter range using a variety of glass micropipette sizes. The new model connects directly to the WPI MICRO2T SMARTouch™ controller, which can also be used with WPI’s UMP3 pump, allowing the pumps to be controlled individually or synchronously. The new injector head has a LED indicator which shows proper communication between the pump and controller. NANOLITER2020 offers improved precision by in-depth plunger displacement validation. The system is easier to use and has a chic silver injector head.
Benefits
- Minimizes loss of costly or scarce samples because injections are performed with mineral oil, back-filled, glass micropipettes, and the sample is front filled.
- Control up to two pumps simultaneously
- Mounts easily on a micromanipulator or a stereotaxic frame
- Precise control over injection volumes and rates (nL to mL range)
- Simple to use touchscreen interface and graphical representation of volume status on MICRO2T controller
- LED indicator offers a visual indication of connectivity
- Perform injections with a foot switch(optional)
- Injector is compatible with different OD glass micropipettes (in the range of 1.1-1.5 mm)
- Costs 15% less than the previous model (NL2010MC2T)!
Applications
The NANOLITER2020 Injector is perfect for making nanoliter to microliter range injections into frogs (Xenopus oocytes), rats, mice, mosquitoes, shrimps, insects (e.g., Brown Planthopper), flies (e.g., Drosophila) and fish (Zebrafish) embryo using glass micropipettes.

Surprisingly good pregnancy story with amazing narration
Format: Kindle
This book was cute, funny, and unexpectedly heartfelt. Pregnancy plots aren’t usually my go-to, but this one felt fresh and fun, with a unique take that totally worked for me. The story leaned fully into the romcom vibes while still delivering a surprising amount of emotional depth.
I absolutely loved the cast—both human and animal. Every character felt charming and well-rounded, and the family dynamics, especially between the brothers, were a standout. Their relationships added so much heart and humor, and I’m already excited to read their stories next.
The audiobook deserves a special shoutout —the narrators were fantastic and brought the humor, emotion, and banter to life perfectly. Overall, this was a cozy, feel-good romcom that made me laugh, swoon, and smile way more than I expected.

Eh
Format: Paperback
I came for the baby contract, stayed for the banter, and left with mixed feelings.
Okay, listen. I wanted to love this book. It had all the ingredients for a delicious, spicy small-town romcom:
✔️ A broody, bearded mountain man who wants a baby but not a relationship (sir, okay...)
✔️ A scrappy, sunshine-y heroine with big dreams and zero time for BS
✔️ Forced proximity, a fake-ish relationship, and... a literal baby contract? SIGN ME UP.
BUT.
While this had moments, the overall execution didn’t quite deliver that knockout punch for me. It was cute, it was quirky, it had potential—but it also felt a little surface-level when I wanted more emotional depth.
🪵 Wyatt is peak grump. Like, grump of the year award. He’s emotionally walled-off and makes a very logical, slightly cold decision to have a baby with no strings attached.
🐾 Trista is feisty, fun, and came to this mountain town to start an animal rescue—but ends up signing up to carry Wyatt’s baby instead. Girl, blink twice if you need help.
Their chemistry? It was there, but it felt more tepid tea than slow-burn wildfire. Some of the banter made me smile, but a few moments dipped into cheesy instead of charming. I wanted more genuine connection before we jumped into big emotional decisions.
Quote that kinda sums it up:
“I don’t want forever. I just want a baby.”
Trista: blinks in rom-com disbelief
Also, Wyatt's whole “no love, just baby” rule was giving ✨robot with a sperm bank✨ vibes for too long. I wanted him to soften sooner so I could fall for him the way I know I was supposed to.
That said, it’s a fun, quick read with some sweet moments and the promise of more drama in future books. If you’re looking for a quirky romcom with a non-traditional setup and can roll with a little emotional whiplash, you’ll still have a good time.

Nine Month Contract
Format: Audiobook, Format: Audiobook
Nine Month Contract by Amy Daws
Mountain Men Matchmaker series #1. Contemporary romance. Small town. Can be read as a stand-alone but for completeness, this is a spin-off of Last on the List from the Wait With Me series. Additional troupes include grumpy-sunshine, 10-year-age-gap, and curvy-FMC.
At thirty-eight, Wyatt Fletcher knows what he wants from life. And that’s family. And a baby. Wyatt misses his father’s wisdom and guidance. He’s envious of his older brother Max’s family. It’s time. Sure, his brother putting an advertisement in Craig’s list for a surrogate was supposed to be a joke, but it was actually fortuitous. But twelve interviews later, Wyatt isn’t having much luck in finding the right woman.
Everly Wyatt, Wyatt’s 18 year-old niece literally runs into a woman at the fertility clinic and after talking, decides Trista Matthews is the perfect woman for Uncle Wyatt. She sets them up on a date at the Mercantile.
Trista Matthews needs to move and wants to open a wildlife rescue facility. Earning the money as a surrogate, and being able to live temporarily on the mountain is perfect for her plans. She’ll live in the renovated barn and have a place for any rescues she saves. Once she has the baby, she can walk away without any qualms. That’s what her parents did. And her sister. It’s normal in her experience to be able to walk away.
So Wyatt and Trista sign a contract and take the next steps, separately, to get her pregnant.
And then they tentatively become friends and maybe a little lust is involved.
🎧 I alternated between an ecopy and an audiobook version of this story. Two awesome dual narrators, Erin Mallon and Teddy Hamilton, bring the book to life, making it impossible to put down. Engaging, titillating, and more than a few laugh out loud moments, made this romance utterly delightful. And steamy.
I did listen to this above a speed of 1.5 to more closely match my reading speed and local conversion.
Even before this story fully ended, I downloaded a dozen more of the author’s back catalog.
Can’t wait for the next in this series in June.
The irreverence of the advertising is ridiculous yet sets the tone for the mountain man that wants his mountain retreat but also wants his family close. Perfect setup.

Heartfelt, Funny, and Deeply Moving Romance.
Format: Paperback, Format: Paperback
Amy Daws delivers a thoughtful and emotionally rich standalone with Nine Month Contract, a story that balances humour, sensitivity, and heartfelt character growth.
Wyatt Fletcher is a reclusive mountain man in his 40s who lives on his own mountain near Boulder, Colorado. Beneath his rugged exterior is a man with a deeply personal dream of becoming a father. Trista enters his life through a carefully structured surrogacy agreement, and what follows is a slow-building connection grounded in trust, mutual respect, and emotional vulnerability.
The author handles the topic of surrogacy with care and compassion, creating a narrative that feels intentional and respectful throughout. Rather than relying on shock value, the story focuses on the emotional journey of two people navigating a life-changing commitment together.
One of the strongest aspects of the book is the Fletcher family. Wyatt’s close bond with his siblings, sister-in-law, and niece adds warmth and humour, with plenty of light-hearted moments and supportive interactions. Their dynamic highlights the importance of found family and creates a welcoming contrast to Trista’s more difficult upbringing.
Trista’s passion for rescuing animals adds charm and levity to the story, while also revealing her generous heart. Her dream of running a wild animal rescue gives her character purpose and depth. The farm setting, complete with an ever-growing cast of animals, provides many memorable and amusing moments without overshadowing the emotional core of the book.
Wyatt expresses care through consistent actions rather than grand gestures, offering steady support and reliability. While their emotional pacing differs, the character development feels realistic and earned. The story addresses challenges around differing expectations of parenthood in a way that feels genuine and meaningful.
The story concludes with a satisfying resolution and a bonus epilogue that offers a glimpse into the future of the characters. Readers who enjoy emotionally grounded romance with humour, strong family dynamics, and thoughtful storytelling will likely find this book rewarding.

A Delightful and Unputdownable Read!
Format: Paperback
"Nine Month Contract" was an absolute pleasure to read. I was immediately drawn into Trista and Wyatt's story and found it to be a genuinely light and refreshing book. Seriously, I couldn't put this down!
What truly made this book shine for me was the beautiful development of the relationship between Trista and Wyatt. K.S. Wright crafts a believable and engaging connection that keeps you rooting for them from beginning to end.
However, the element I loved most was the author’s dedication to Trista’s personal growth. It was refreshing to see her character arc handled with such care. Wright allows Trista to be wonderfully vulnerable without ever compromising her strength or losing her essential self. She remains true to who she is, even as she navigates challenging circumstances, which made her a deeply admirable and relatable heroine.
✨ Tropes You'll Find in This Book:
- Forced Proximity
- Slow Burn
- Grumpy/Sunshine
- Contract/Arranged Situation
- Found Family
If you are looking for a fantastic contemporary romance with great chemistry and a compelling journey of self-discovery, look no further. Highly recommend!
