Most sterile fluid dispensing is done with familiar hand-operated pipette aids. While adequate for low-volume applications, hand-operated pipetting is tedious for large-scale cell culture due to the multiple aspirate, move and dispense steps. In addition, processes such as pipetting into angled T-flasks or removing/inserting caps can be cumbersome, often requiring both hands and desiring a third.
The Pipeline dispenser eliminates the tedious nature of these tasks. To operate, the user simply snaps in a sterile Peripette (Peristaltic Pipette), lifts the pump head mechanism, inserts the source bottle and lowers the assembly. After setting the desired volume, the user places the destination container under the output spout and initiates the dispenser. Pipeline then performs the fluid transfer in a one-step operation. This saves time and reduces the stirring, repetitive motions (aspirate, move and dispense) as required for hand pipetting.
Additionally, the dispenser is ready to repeat the process, as many times as is needed, until the source bottle is empty. With increased efficiency and high throughput capabilities, Pipeline facilitates repetitive laboratory tasks.
For example, Pipeline provides a fast and accurate means for preparing multiple aliquots of a common reagent. Pipeline is also compatible with dispensing cells and suitable for use in cell culture. In multi-step procedures, one can use an aspirator along with the Pipeline to exchange cell culture media, solutions and reagents without the need to change multiple pipettes.
Overall, the Pipeline dispenser enhances laboratory protocols by promoting consistent technique. The Pipeline is capable of dispensing in two different modes. The first mode dispenses a user-defined volume of fluid per switch activation, and the second mode dispenses continuously during switch activation. In addition, three different dispense speeds are possible, which allow for the device to be tailored to the most demanding cell culture applications.
The user also has the ability to save and recall up to 8 pre-programmed settings, and the unit can be activated via front panel switch or foot switch. The accuracy and precision of the dispensed volumes are similar to serological pipettes (see specifications). The Pipeline also provides an RS-232 interface if automation or remote operation is required.
