1、aseptic pipe machine

BioWelder® Aseptic Piper - Fully Automatic Hose Assembler

BioWelder® can be used to interconnect thermoplastic hoses on disposable bag systems, and the two hoses are individually inserted into the tube holders, which are cut by the blades and fused together. The blade remains sterile and pyrogen free throughout the operation. In this way, sterile connections can be easily achieved in a non-sterile environment. The tube holders are available in a variety of sizes from 1/4" to 3/4". The unit uses integrated circuit chips to identify tube holders of each size, ensuring high quality hose connections.minimize the risk of operational errors.

BioWelder® Total Containment Sterile Pipe Receiver

———The large size filled liquid pipeline automatic aseptic welding device

BioWelder® TC can be used to interconnect thermoplastic hoses on disposable bag systems, and both in clean and non-clean areas, the BioWelder® TC provides an aseptic connection to empty lines or filled with liquid lines. Place the tube holder, hose, and blade into the BioWelder® TC, the touchpad is activated, and the tubing connections are automatically completed. The infrared sensor controls the temperature of the blade throughout the connection process. The blade heats up to the heat source, then cools to the soldering temperature, cuts the hose and connects. Tube holders are available in a variety of sizes from 3/8" ID x 5/8" OD to 3/4" ID x 1" OD. BioWelder® TC automatically recognizes specifications and ensures high quality tubing connections. The risk of mistakes is minimized.

2、 aseptic sealing machine

BioSealer® Sterile Tube Sealer - for permanent and reliable thermoplastic hose seals

BioSealer® is primarily used to safely separate the thermoplastic hose from the disposable bag system from the system. BioSealer®'s two ceramic heating elements compress and heat the tubing placed in it, and the high temperature and pressure fuse the tubing into a homogeneous section, which can be cut with sharp scissors. The unit can be used for the sealing of thermoplastic hoses with 1/4"- 3/4" OD and is ideal for use with single-use sterile reservoir technology. BioSealer® has a choice of mobile sealing heads. The sealing head can be used up to 3 meters away from the mainframe, making it easy to adapt to various space requirements.

• Housing: stainless steel

• Extrusion head: aluminum (anod plating)

• Maximum tube outer diameter: 3/4", minimum tube outer diameter: 1/4"

• Sealing cycle: 1-4 minutes, depending on hose size and material

• Hose type: thermoplastic hoses (eg C-Flex®, Advantaflex®, SaniPure® 60, FluiSoft® and Pharmed® BPT)
