PharMed BPT Tubing Set (Peri P)

PharMed BPT Tubing

PharMed BPT tubing is specifically formulated for use in the pharmaceutical and biotechnology industries. Its biocompatible fluid surface and exceptional flex life make it ideal for transferring sensitive bioprocessing fluids. This tubing is designed to excel in various applications, including cell harvesting, media processing, vaccine manufacturing, aseptic filling, and diagnostic testing.

One of the standout features of PharMed BPT tubing is its durability. It can withstand repeated clean-in-place (CIP) and steam-in-place (SIP) cleaning and sterilization processes. Additionally, it can be autoclaved up to five times or subjected to gamma irradiation without compromising its overall service life. This tubing’s exceptional flex life and wear properties ensure it outlasts silicone tubing in peristaltic pumps, minimizing downtime due to tubing failures.

PharMed BPT tubing offers excellent gas barrier properties with very low permeability, protecting sensitive fluids from gas ingress. The opaque nature of the tubing also safeguards light-sensitive fluids from visible and UV light exposure. Its thermoplastic elastomer (TPE) composition provides good chemical resistance, although some degradation may occur with long-term exposure to organic solvents, oils, and fuels.

This tubing is USP Class VI and USP compliant, making it suitable for a wide range of applications, from general-purpose to laboratory and single-use scenarios. PharMed BPT tubing is available in various sizes to provide flexibility in covering optimal flow rates with the Daisy Peri P pump. For the nominal flow rates with these tubes, see the “More Information” section of the Daisy Peri P pump.

Although PharMed BPT tubing is more expensive than silicone tubing, it lasts up to 30 times longer in peristaltic pumps and sheds far fewer particles during pumping.

Installation on Daisy Peri P Pump

Attaching these tubings to the Peri P pump is straightforward. It is possible to use micro-tubings other than the ones provided by Scalables, provided that:

1. The spacing between stoppers is 72 mm.
2. The wall thickness is below 1.5 mm.

The opening at either end of the Peri P cartridges is approximately 3 mm wide, designed to hold the stopper in place. If the tubing wall thickness exceeds 1.5 mm, the tubing may pinch, causing excessive resistance, breakage, leaks, and overworking the pump. The PharMed BPT tubing provided has a wall thickness of 0.86 mm, ensuring proper operation. Maximum recommended outer diameter (OD) is ~4.5 mm.

These tubings can be connected to other PharMed BPT or silicone tubings to design a flow system. PTFE tubing may also be used where stiff tubing downstream of the pump is required.
