Plunger-free pipetting

1

Hi folks,

I’ve been salivating over the Veya and Lynx recently because of their plunger-free liquid moving capabilities recently. If I think about it critically, there’s not a ton of need to have unlimited blowout volumes, but it just sounds so… liberating. After that long, high-volume mix, the thought of watching those trapped slivers of liquid slide all the way down from the top third of the tips gives me shivers.

Anyway. I probably won’t get one because there are so many Fluents and Starlets being auctioned off for less than $10k these days, and we don’t even need to do that kind of heavy pipet mixing at my current job. I’m just wondering if anybody has had experience with both traditional and plunger-free systems, and could talk a little bit about their impressions.

I didn’t know the Lynx was plunger-free! How does it work?

Festo has an air pressure based dispensing module but it’s not integrated in any off-the-shelf robots

Are those from the Covid lab systems?

Eesh.

They use vacuum and positive pressure, and claim to be able to measure the volume moved via the pressure differential between two points in the line, liquid class free. I don’t really get the underlying mechanics, but whoa mama (fanning face convulsively)

There is quite a bit of noise about the piezo effect pipetting lately, for example, Hamilton’s ultra-low volume dispensing, M2 Automation GmbH and Dispendix. These are piston free, but all all nl to ul, as I gather.
