INTEGRA Bulk Reagent Dispenser
A cornerstone of the WELLJET's design is the innovative EasySnap™ dispensing cassettes, which utilize molded silicone tubing at the pump interface. This unique construction eliminates the need for time-consuming and often inconsistent recalibration, guaranteeing channel-to-channel precision and significantly reducing operational costs and maintenance complexity. Furthermore, the system is fully compatible with all standard ANSI/SLAS classified plate formats, spanning from 6-well up to 1536-well plates, ensuring unmatched versatility for any laboratory workflow.
User experience is enhanced by a large, high-resolution touchscreen interface that facilitates intuitive and effortless programming. This simplifies the creation and execution of complex dispensing protocols, drastically lowering the learning curve for new operators. When combined with the optional WELLJET Dispenser Stacker, the system achieves full walk-away automation, processing plates quickly and reliably with its integrated and robust lid-handling function, maximizing throughput for demanding applications.
Dispensing accuracy is often compromised by the intrinsic material variation in traditional extruded tubings, leading to inconsistent results across different plate channels. The use of molded silicone in EasySnap cassettes standardizes tubing dimensions, directly solving channel-to-channel precision variations without requiring tedious in-field recalibration.
Laboratories typically face high operational costs associated with frequent replacement and complex maintenance of dispensing systems. The WELLJET design, featuring economical EasySnap cassettes, offers reduced running costs and superior reliability, protecting the valuable lab budget over the instrument's lifetime.
The transition between different plate densities (e.g., 96-well to 384-well) can be cumbersome and limit the instrument's utility. The WELLJET system handles a comprehensive range of ANSI/SLAS plate formats, from 6-well up to 1536-well, providing flexibility for various low and high-throughput screening applications.
Manual or semi-automated dispensing of bulk reagents is a significant bottleneck, consuming excessive personnel time and introducing human error. The WELLJET delivers rapid plate processing times, drastically increasing laboratory throughput and freeing up staff for more critical scientific tasks.
Contamination risk is a constant concern during high-volume transfers, particularly for sensitive biological assays. The system employs non-contact dispensing, ensuring that the dispensing cassette tip does not touch the liquid in the well, thereby preserving sample integrity.
Programming and operating sophisticated laboratory equipment can involve a steep learning curve, leading to errors and delays. The large, high-resolution touchscreen interface offers intuitive, self-explanatory controls, minimizing training time and maximizing immediate operational efficiency.
Continuous high-volume aliquoting requires continuous manual input, preventing true automation for full workflows. When paired with the optional stacker, the system provides walk-away capability, reliably managing plate loading, dispensing, and stacking for extended, unattended runs.
Achieving accurate low-volume dispensing, especially below 5 µl, is challenging for many bulk dispensers based on peristaltic technology. The WELLJET utilizes specialized pump engineering to achieve reliable and accurate dispensing across an exceptionally wide range, starting as low as 0.5 µl.
