MANTIS® Liquid Dispenser

MANTIS® Liquid Dispenser

Small, Versatile, Precise

More Than a Reagent Dispenser

While traditional handheld pipettes or larger automated liquid dispensers greatly deteriorate in accuracy and precision below 2 µL volumes, the MANTIS® automated liquid dispenser excels at low-volume dispensing in a wide variety of scientific workflows.

Enhance Laboratory Efficiency

Efficient research means that reagent dead volumes, tip consumption, and reaction volumes are minimized.  

The MANTIS liquid dispenser dispenses volumes from 100 nL to 100s of mL allowing researchers to commonly run 2-5 µL reaction volumes in genomics and screening workflows.

To minimize dead volume, reagents plug directly into the microfluidic chip. Dead volumes are further reduced to just 6 μL by using pipette tips as reagent reservoirs, making the MANTIS ideal for dispensing even the most precious reagents.

Normalize Your Assay Plate, Quickly and Easily

  • The MANTIS software automatically calculates the normalization values for you
  • The Continuous Flow (CF) chip bulk dispenses at >600 µL/sec, therefore, quickly normalizing each sample tube, well, and plate
"Using MANTIS, I recently performed a high-throughput qPCR-based drug screen in stem cell derived retinal cells and acquired reliable data with homogeneity, precision, and faster dispensing. The instrument is user-friendly and has easily paid for itself in the savings associated with both expensive reagents and tip consumption in our lab. The MANTIS is an essential tool for any lab that wishes to perform the most efficient and reproducible genetic analysis.”

Dispense Beads and Cells with Ease

Magnetic beads are an efficient means for extracting and purifying nucleic acids. Conventional pipetting may result in the non-uniform dispensing of mag beads, leading to a lack of reproducibility. The ability of the MANTIS to precisely dispense high viscosity liquids allows uniform dosing of beads reducing operating costs and plastic waste.

Cells can be extremely sensitive, requiring additional care during handling, making the scalability of assays very challenging. The dispensing action of the MANTIS liquid dispenser is gentle enough to dispense even the most delicate cells, such as primary neurons, while maintaining cell viability.

Use of Microfluidic Technology in MANTIS

At the core of our dispensers is patented microdiaphragm pump that meters and dispenses discrete volumes of liquid. This valve cluster can fill and dispense as fast as 10 times per second (exact speed depends on specific product). This proven technology is both incredibly precise and viscosity independent.

"FORMULATRIX is providing products that are state of the art in terms of fluidic and nanofluidic liquid handling. The technological excellence of these liquid handlers allows us to develop tailored scientific solutions that are extremely relevant for our collaborators' applications and workflows."

Highly Reproducible Data

Since liquid handling imprecision impacts experimental reproducibility, researchers consider CVs to be a vital factor when considering the automation of their research. 

At the core of the MANTIS' microfluidic dispensing chip is a valve cluster that measures and dispenses discrete volumes of liquid. This valve cluster has two micro-diaphragms (select either 100 nL and 500 nL or 1 μL and 5 μL) that can fill and dispense as rapidly as 10 times per second.

"...[The Mantis liquid dispenser] helps us minimizes variation in sample prep.  It is the most economical way to for us to reliably dispense sub-microliter volumes to each of our wells and help minimize our volumes..."
