The Daisy Peri T is a versatile and efficient peristaltic pump designed to be a reliable workhorse for a wide range of laboratory and process applications. The pump head can be opened and closed with a single hand. A plain tubing is held in place by adjustable grabbers on either side of the head, obviating the need for any anchors or other specialized hardware on the tubing itself. With the option to choose between 3 or 6 rollers, the pump provides reliable and consistent fluid transfer for low to moderate flow rates (up to several hundred ml/min).

This module is ideal for every day operations in the lab. Use it to fill media containers, transfer reagents, or run cell perfusion experiments. It can be used as a dosing pump with a quick calibration, or as a recirculation pump in a continuous closed process.

New tubing installation is straightforward. Simply turn the knob on the upper pump head block counterclockwise 180 degrees to open it (1), and place the new plain tubing over the rollers and through the end grippers on either side of the pump head block (2). Finally, turn the knob clockwise 180 degrees to close the upper block fully. That is it! There is no need for tube stoppers or other hardware.

Below is a table summarizing the nominal flow rates expected from the Daisy Peri T pump with the different tubing sizes available from Scalables.

Note that these flow rates correspond to negligible back pressures on the system. Whenever there is a non-negligible flow restriction or pressure drop along the pump’s flow path, the user is advised to run their own calibration.

The Daisy Peri T Pump is designed for long-lasting performance, minimizing the need for frequent maintenance or replacements.

Peristaltic Pump Tubing: Essential Selection and Maintenance Tips

Peristaltic pumps offer versatile fluid transfer solutions, but their efficiency and longevity heavily rely on proper tubing selection and maintenance. Let’s delve into key considerations and actionable tips to ensure optimal performance and durability of peristaltic pump tubing.

Understanding Wear and Tear

Over time, peristaltic pump tubing can degrade, primarily due to damage from the pump head’s rotor. This damage often stems from incorrect tubing length, causing repetitive friction with the rotor edge during operation. This friction accelerates wear and tear, leading to potential bursting after extended use. Prompt replacement and preventive measures are crucial to mitigate such issues.

Selecting the Right Tubing Material

Choosing the correct tubing material is paramount. Conduct a chemical compatibility test to ensure it withstands the pumped substance and operating conditions. Temperature, system pressure, and bore size are critical factors influencing tubing selection. Optimal dimensions and material quality enhance tubing lifespan and prevent premature failures.

Installation and Maintenance Best Practices

Proper installation is fundamental. Ensure tubing is straightened and securely clamped to prevent displacement. Regular inspection for wear signs like thinning or abrasions is recommended. Prompt replacement upon damage minimizes downtime and maintains fluid transfer efficiency.

Essential Maintenance Tips

Regularly monitor tubing life expectancy, considering factors like transparency, gas permeability, and regulatory compliance. Additionally, recalibrate systems as needed to address flow rate drop-off over time. Conduct extractable and leachable studies for applications requiring stringent quality control.

If pump tubing breaks, creating a leak over the peristaltic pump, promptly wipe the pump head and body dry. Depending on the type of fluid leaked, spraying and wiping with 70% isopropyl alcohol might be needed. Make sure the pump head and rollers are clean, free of any residue or particulates before installing a new tubing.

Good quality pharma BPT tubing can last up to 1000 hours of operation with water. If there is considerable back pressure, increased temperature or chemical interactions between the fluid and the tubing material, this lifetime will be reduced. Silicone tubing can last up to 200 or more hours of operation.

Connecting Peristaltic Pump Tubing

Pay attention to suction and delivery pipe bores, ensuring compatibility with tubing size. Use larger bore tubing for viscous fluids and maintain flexible tubing lengths to minimize impulse losses. Optimize pump speed based on application requirements to maximize tube life, flow rate, or accuracy.

Investing in Quality

Choosing high-quality tubing from reputable suppliers minimizes risks of failure and ensures consistent performance. While cost-effectiveness is essential, prioritize durability and compatibility with application requirements to optimize long-term reliability. We provide only the highest quality tubing selections on our site.

Conclusion

Peristaltic pump tubing plays a crucial role in fluid transfer operations, and proper selection and maintenance are vital for sustained performance. By adhering to best practices, monitoring wear, and investing in quality materials, users can enhance pump efficiency, minimize downtime, and prolong tubing lifespan, ensuring reliable operations across diverse applications.
