axiVENd - Model Precise Drop™ II -Micro-Dispensing System
Traditional hand pipettes and liquid handlers have very poor accuracy and precision below 2 microliters. Yet, in order to maximize the results one can obtain from limited protein availability, miniaturizing assay volumes is critical. The Precise Drop II was created to address this need for sub microliter accurate and precise volume reagent dispensing into microtiter plates.
The Precise Drop nanoliter dispenser represent the latest in engineering design and technology, developed by experts in robotic control and laboratory automation at LGR. It was inspired by the classic BioRaptr, modernizing electronics and software, and packaging the new technology into a much smaller design.
Our and LGR’s teams combined have decades of experience in life science robotics, engineering custom projects and science to meet customer needs.
Precise Drop II system packages this expertise into a line of flexible dispensers for both benchtop and full automation users. These dispensers are designed and engineered to be compact, low cost and fully customizable.
Major applications include:
- ELISA assays
- Assay Development & Design-of-Experiments (DoE)
- Library prep for Next Generation Sequencing (NGS)
- Cell-based and biochemical assays
Flexible Software for Precise Dispense Control
Precise Drop delivers unparalleled flexibility, with a self-contained browser-based control system and software that scales right along with the system. Pick the configuration you need now; the software remains the same regardless of system as you grow. Add channels, change your substrate, and integrate into a larger system. The control system and software remains the same.
Each dispense channel has its own dedicated microcontroller, providing independent control and easy scalability. Channels can be coordinated, individually timed, or timed based upon some external event. This is critical for both multi-well dispenses and for multi-line dispense on membrane.
Each channel can dispense different volumes using identical or different size valves. Proper current drive control to each valve ensures that the valves last longer, deliver consistent results, and avoid overheating. Axis speed is fast while allowing settling between positions.
The software interface is browser-based, allowing operators to set up protocols and recipes using a smartphone, iPad, netbook, laptop, computer or any other web-based device. In addition, Precise Drop can interface to SiLA and TCP/IP socket.
Operators use the advanced software interface to:
- Develop protocols/methods for dispensing
- Create simple and advanced recipes from CSV input
- Control valves and calibrations, with each channel fully adjustable
- Define XYZ location
- Move dispense head to wash, prime and clean station
- Track users and system error logs
- Define access and permissions
- Access online system help
