PipettorPlus is the World’s first and only differential Pipettor. We developed it to be the World’s best pipettor – and we think it is. The BROCHURE shows the mechanism, features, and specifications.
You can see the 2 husky pistons facing each other even as you use it, with ambient air stabilizing the internal temperature, so you don’t need to worry about heat from your hand. You can also see the large, compliant O-ring seal and appreciate how reliable the sealing is.
Those 2 pistons you see differ very slightly in diameter. It is that very difference that gives the precise resolution by Differential Displacement – without any skinny piston and the sealing difficulties that go with that. Even our models that go down to 0.2 µL have those sturdy pistons and rugged seals that don’t leak. Failed aspiration low outliers from occasional seal leaks that you may be accustomed to do not occur here.
Once aspirated, you can dispense exactly as you do now – by touchoff-and-drag or immersion. But if you want, the PipettorPlus will let you dispense by blowoff, contact-free and with no possibility of contamination. Just point where you want your aspirated sample to go and push, and the sample will go there. No contact with the receiving site in environments that are sterile or where contamination is a disaster.
A few movies below amplify what the brochure shows.
Shown with an adjustable 1 µL – 20 µL Queen Bee unit surrounded by
5 devoted fixed volume worker drones for 0.6 µL, 1 µL, 2 µL, 5 µL and 10 µL.
Fastest, easiest and most accurate low volume pipetting on the planet!
PipettorPlus Fast Small Volume Array
Fixed-volume Differential Pipettors are used to provide a very fast array of 3 drops each of 10 µL, 5 µL, 2µL, 1 µL and 0.75 µL. The pipetting transfers are all contact-free and clean.
PipettorPlus 1 µL Rapid Pipetting
5 1 µL drops are rapidly pipetted by a fixed volume Differential Pipettor with regular tips and then with filter tips to show there is no difference.
NEPTUNE96 Overview
As described in the BROCHURE, NEPTUNE96 is a semi-automated, 96-channel desktop Differential Pipettor that can pipette and dispense with clean, contact-free delivery down to 200 nanoliters with untouchable precision and accuracy. Rapidly accesses 384 well plates with quadrant-locater.
Pleasing to use and elegant, NEPTUNE96 exemplifies the best and most sensible sharing of the operating interface between human and machine. Run by a PC with our powerful and customized DRD Visual Basic control software, the electronics and logic move the pistons for superb aspiration precision. It gives just the right dispensing velocity for contact-free delivery as you want it – ranging from fast “blastoff” to gentle “plopoff” delivery that harms neither babies nor genetic fragments. But for moving the pipetting head module up-and-down, or the 3-position carriage fore-and-aft, it defers to your swift and decisive human hand on the comfortable knob handle, knowing that you can’t stab yourself and don’t need a clumsy protective shield or bubble.
NEPTUNE96 with Inserter Head Tips with 1 µL
96 tips with 1 µL of liquid are shown here in this Inserter model. The Deska Magenta mandrel/tip combination delivers down to 500 and even 250 nanoliters contact-free with high precision and accuracy.
NEPTUNE96 1.2 Minute Overview Movie
This starts the 10 minute BASIC STORY movie at 7:01 minutes for the NEPTUNE96 section. The NEPTUNE96 section ends at 8:10, but the movie will keep running unless you stop it or move out of it.
7:01 – 8:10 section on NEPTUNE96
The movie shows a brief cross-sectional graphic, a 384 well transfer in a tall multi-stage high throughput robot, and ends with a closeup of the long aspiration through the 97th Cyclops Eye.
NEPTUNE96 Animated Cross Section Graphic
This is a pleasing and silent cross-sectional graphic that shows what is going on inside – as Superman could see it. You can see how the pairs of seals sweep down over the two pistons, and then how only 1 piston closes the gap to give the clean blowout. Your non-Vulcan mind will find this very helpful in understanding this extraordinary mechanism, so elegant in its simplicity that it can be difficult to grasp on that very basis.
NEPTUNE96 Long Excursion Stroke Movie
This is a dual-screen movie closeup during sub-microliter aspiration. It shows the fabulous long excursion stroke that our unique differential mechanism provides that ensures the great aspiration precision and accuracy. Unlike the restful silent presentation of the animated cross-section graphic above, this movie is robustly narrated.
NEPTUNE96 Extensive Movie
This is a long (5 minute) and labored panoply of NEPTUNE 96’s extraordinary capabilities, suitable only for those who are seriously interested.
