Improve Safety, Reliability,
and Function with New Fluidics Innovations
Pulsation-free pump technology boosts precision and safety in fluid handling
From jean manufacturers handling dye synthesis to alcohol distillers making aged bourbon, and electric vehicle battery manufacturers, pumps can be found
in very diverse settings. Finding a pump that works for a variety of different processes with minimal setup and maintenance while adhering to reproducibility levels required for compliance can be like finding a needle in a haystack. However, new pump designs can fulfill many of these needs simultaneously, making them a solution for the wide range of research and development needs facing today's scientists. As Jim Feltman, the Vice President of Tacmina USA Corporation, said, "The pump should be the least of anyone's worries … It should be a physical device that is easy to program and implement in a safe way."
ACCURACY AND REPRODUCIBILITY
These two elements constitute major pillars of good science. However, when running experiments with pumps, researchers can be faced with a lack of control and precision. Flow rate inconsistencies can compromise research integrity, especially in dosing or synthesis experiments. Implementing precise control mechanisms and feedback systems improves reproducibility and accuracy, strengthening the robustness of results.
A shift from batch production underscores the critical requirement for dependable and flexible pump setups in experiments. Labs that embrace improved flow rate control and stable long-term performance will ensure the reliabili- ty of their experiments.
With a consistent flow rate and simple operation, new pump designs contribute to improved accuracy and reliability.
PULSATION IN THE LAB
Diaphragm pumps use a flexible barrier that moves back and forth to create suction and discharge fluid. However, this reciprocating movement leads to a pulsing flow of fluid, which is impractical for experiments requiring continuous and smooth fluid flow. Inlet and outlet valves can exacerbate this pulsation issue, adding to the uneven movement of fluid.
To mitigate pulsation, lab staff often use air chambers or dampeners. However, these solutions can introduce new challenges including loss of control and additional main- tenance. Alternative pump technologies have emerged to address these problems without the drawbacks of cham- bers and dampeners. These new designs offer improved reliability and affordability. The nature of technology and equipment is one of continual improvement, with different needs adding potential expenditures such as revalidation or recertification.
PRODUCTIVITY AND EFFICIENCY
Labs are under tremendous pressure to continually increase throughput while reducing costs and maintaining high standards. The added labor and materials costs associated with pump maintenance, training, and service calls are a drain on already-stretched resources, and slow overall lab productivity. Because of these demands, labs need a pump that is designed with ease of use and training in mind. Learned skills needed to run and maintain lab equipment can cost the lab considerably, especially when there is also a need for cross-training for adequate cover- age, onboarding, and refresher training.
New pump models feature low-maintenance technology that emphasizes quick checks and easy repairs. In contrast to traditional pumps' time intensive maintenance tasks such as managing oil changes, disassembling pumps to replace membranes, and conducting other routine maintenance, the tasks are less labor and time intensive in new pump models, and can be completed quickly by non-experts. This is because these models are simple to maintain, with infrequent maintenance needs, straightforward routines, and reliable operation mechanisms. They incorporate modular components that can be quickly detached or replaced without the need to extensively disassemble the entire unit, as each part of the pump is a distinct section. Tool-free access and quick-release connections also enable easy access without requiring specialized tools or expertise. These design features enhance lab productivity and efficiency while conserving resources.
Some pump models require no special tools to change the pump head or remove it for easy cleaning and maintenance.
HAZARDOUS SUBSTANCES REQUIRE ADDITIONAL MEASURES
For labs working with volatile or hazardous chemicals or sensitive samples, safety is of utmost importance. Contamination, leaks, exposure to air/moisture, and incompatible materials coming into contact during experimentation can increase the risk of an accident resulting in injuries or lab or sample damage. Equipment with enhanced safety measures like sealed systems and automated pressure ad- justments and release valves is even more important when handling hazardous samples.
Smoothflow pumps have embedded measures to protect users, the equipment, and the sample while working with any type of substance, including:
- Remote control from an intelligent device
- Overpressure protection integrated into pumps to prevent overpressure situations can also alert the user if pressure has exceeded the safety limits, and can also have an added feature of excess pressure release
- Options for specific materials that are compatible with experimental substances, reducing the risk of chemical reactions or degradation that could compromise safety
BENEFITS IN PRACTICE: THE Q-SERIES SMOOTHFLOW PUMP
The Q-Series Smoothflow pumps offer scalable flow rates ranging from 1 microliter to 100 milliliters per minute, ensuring versatility and providing pulsation-free continuous flow. These pumps feature a precision motor, offering exceptional control for advanced safety measures and smooth daily operations.
Repeatability is within plus/minus one tenth of a percent of flow rate, configurable to 1 microliter per minute. The pumps are designed with a simple inner setup to reduce wear and maintain accuracy, resulting in a long service life and low operating costs. They can be constructed using specific materials to meet a variety of lab needs, such as Hastelloy for pharmaceutical applications.
Setting up and calibrating the Q-Series pumps is straightforward, and their pump heads, available in dif- ferent materials, can be quickly swapped to accommodate changing liquid requirements.
Designed for durability and simplicity in use, the pumps require maintenance checks only every 4,000 hours of run time, with a simple maintenance routine that takes just 5-10 minutes. Training on these pumps can be completed in 10 minutes and conducted on-site or using custom training videos that can be stored for future reference.
Safety features of the Q-Series pumps include internal protection to prevent overpressure, and they are not dam- aged by running dry, eliminating risks of galling, seizing, and excessive wear. In the case of a blockage, the pump pauses until fixed, then resumes from the same point, avoiding costly experimental repeats. A two-second power switch delay mitigates accidental power loss, preventing pressure loss and experiment failure.
Thith a commitment to efficiency and noise reduction, the distinctively pink Q-Series Smoothflow pumps are used in a diverse range of labs, including electric vehi- cle battery, specialty chemical, pesticide and herbicide, flow cytometry, and cellular biology labs. The Q-Series Smoothflow pumps represent an evolution towards
smarter, more efficient laboratory equipment, empowering researchers with innovative solutions.
