FREQUENTLY ASKED QUESTIONS

GD-L_LargeGasDispursionTube_web_3216v1.jpgGas Dispersion Tube, Large

Our large gas dispersion tube is perfect for providing aeration in beakers and other solution reservoirs. The GD-L tube provides a fine bubble size to optimize gas exchange. It can be cleaned using 0.1-1 M hydrochloric acid to ensure long life and optimize performance. Be sure to rinse and bubble through with distilled water after acid-washing the GD-L.

Features: Includes 2′ of 1/4″ ID Tygon Tubing

Specifications
Porosity25-50 micron
Length135 mm
Diameter7 mm

GD_MiniGasDispersionTube_web_8731v1.jpgGas Dispersion Tube, Miniature

Our miniature gas dispersion tube is designed specifically for providing aeration in the vessel bath of our CH series vessel chambers. It is also very useful in applications requiring gas dispersion with a minimally invasive dispersion tube. The GD tube displaces very little fluid, occupies minimal space, and provides very fine bubbles (porosity of the glass frit is 4 to 8 µm). A high-quality flow valve is supplied for controlling the gas flow rate. The GD tube can be chemically cleaned (e.g., 1 N HCl) to ensure long life and optimized performance.

Gas Dispersion Tube, Miniature – Straight

Our miniature gas dispersion tube is designed specifically for providing aeration in the vessel bath of our CH series vessel chambers. It is also very useful in applications requiring gas dispersion with a minimally invasive dispersion tube. The GD-MS features a straight tube that displaces very little fluid, occupies minimal space, and provides very fine bubbles (porosity of the glass frit is 4 to 8 µm). A high-quality flow valve is supplied for controlling the gas flow rate. The GD-MS tube can be chemically cleaned (e.g., 1 N HCl) to ensure long life and optimized performance.

OX_MiniatureGasExchangeOxygenator_web_9080v1.jpgGas Exchange Oxygenator, Miniature

Our miniature oxygenators are designed to provide gas exchange in the perfusate delivered to cannulated vessels in our vessel chambers. They feature luer ports on the inflow and outflow sides, and are ideal for gas exchange in-line with blood vessel perfusion, or perfusion of many other isolated vessels, organs, or tissues. OX oxygenators utilize a fixed gas exchange cartridge, which can be reused with appropriate care.

Features

  • Allows gas exchange into perfusate
  • Eliminates foaming when oxygenating protein-containing buffers
  • Handles perfusion rates in the µl/min range to several ml/min
  • Large gas exchange surface area
  • Minimal perfusate pressure loss
  • Superior performance to bubble and flat sheet membrane oxygenators
  • Polypropylene hollow micro fiber array
  • Hollow microporous fibers: 240 µm ID, 28 µm wall thickness
