Abstract: This document is Velocity11 VPrep 384 Channel 10 µL Tip Accuracy and Precision Technical Note. It introduces the features and characteristics of the product, including applicable range, accuracy, etc.
This document serves as a technical note for the Velocity11 VPrep liquid handling platform, specifically evaluating the performance of its 384 Channel ST Disposable Tip Head with 10 µL tips. The text highlights the platform's ability to automate routine laboratory processes, increasing throughput and reducing errors compared to manual pipetting. Key features include eight deck positions for various microplate formats and the capability to use interchangeable 8-, 16-, 96-, or 384-channel fixed or disposable tip heads.
| Deck positions | eight |
|---|---|
| Compatible tip heads | 8-, 16-, 96-, or 384-channel |
| Accuracy at 0.3 µL | +4.2% |
| Accuracy at 0.5 µL | +2.6% |
| Accuracy at 2.0 µL | +1.2% |
| General CV performance | 5% |
| General Accuracy performance | +10% |
The performance was tested at the lower end of the practical volume range from 0.3 to 2 µL.
Measurements were determined by dispensing a tartrazine/DMSO solution into dry microplates, filling them with water, and measuring tartrazine absorbance.
Yes, the VPrep is capable of standalone usage in addition to being a component of a robotic laboratory automation system.
