Rapid and accurate preparation of complex crystallization gradients and optimization screens

dragonfly crystal focuses specifically on protein crystal optimization, enabling rapid and accurate preparation of complex crystallization gradients or optimization screen, even with viscous liquids, while eliminating cross-contamination. dragonfly partners seamlessly with mosquito in the protein crystallization screening workflow, streamlining the cycle between initial ‘hit’ identification and high resolution diffracting crystals.

With low dead volumes, dragonfly crystal ® allows laboratories to minimize stock consumption and do more, with less. With dragonfly, researchers can combine a wide range of stocks, of any viscosity, into complex gradients and generate higher quality crystals.

Robust day-to-day operation
Robust day-to-day operation

The dragonfly crystal has a track record of robust performance with no blocking or clogging, maximizing uptime and safeguarding critical research outcomes.

We’re revolutionizing liquid handling

dragonfly enables accurate and repeatable nanolitre to milliliter dispensing, every time, irrespective of liquid viscosity or environmental conditions.

High performance technology

Our liquid handling instruments harness innovative technology to streamline workflows and accelerate research.

Robust, reliable, and easy to use, our products overcome tough technical challenges and enable researchers to focus on the best science.

True positive displacement pipetting

Our true positive displacement syringes are controlled by independent dispense heads located inside the instrument.

Key features:

  • 200 nL – 4 mL dispense range​
  • liquid class agnostic, with no calibration requirement​
  • non-contact dispensing, for minimal syringe consumption​
  • no cleaning or maintenance requirement​
  • zero chance of blocking or clogging
Combines usability and functionality
  • Highly visual, easy to use UI​
  • Flexible sequencing of liquid additions​
  • Automation of time point experiments, allowing for maximum walk-away time​
  • Saving and loading of full experiment setup data, for full reproducibility​

 

The dragonfly designer software is a complementary software package designed to specifically meet the needs of scientists:

  • Intuitive definition of multiple concentration gradients, both linear and high dynamic range n-fold
  • Database of common stocks and reagents used in protein crystallization
  • Calculation of all well dispense volumes, as well as overall reagent requirements​
  • Open source .CSV file output that loads directly into the dragonfly software package​
Integration to enhance protein crystallization screening workflows

SPT Labtech’s complementary MX one mixer enhances protein crystallization screening by allowing researchers to mix any liquid in small wells with no risk of spillage.

The centrifugal forces generated in conventional plate shakers mean that the mixing speed must be limited to avoid liquid spilling from wells. The MX one keeps the plate stationary, allowing for extremely fast mixing of even the most viscous solutions using high-speed oscillation of a disposable pin array.

What our customers say about dragonfly crystal

The Dragonfly has rapidly become an ESSENTIAL tool that significantly streamlines structure determination! Screens that used to take hours to prepare can now be made in under 10 minutes using the user-friendly software and intuitive design of the instrument. Amazingly, the 10-heads are more than sufficient to create screens ranging in complexity from simple x,y gradients to multi-zone optimization. With virtually no dead volume and the fact that you are aliquoting directly into the crystallization tray, the Dragonfly can conserve on those expensive chemicals and rapidly produces a crystallization tray ready for the crystallization robot. The Dragonfly makes optimization of lead conditions a breeze and alleviates the crystallization bottleneck, allowing you to focus more on the science of the target than on the pursuit of crystals.
