- 20 μm porosity polyethylene bed supports are fixed in the column outlet
- Luer lock inlets and outlets on the columns, along with a wide variety of adapters, valves and fittings, provide simple and versatile tubing connections
- Inside diameter is 1.5 cm and length is 100 cm
- Maximum pressure is 1.0 bar (14.7 psi, 1.0 atm, 0.1 MPa)
- Temperature range is 0 to 50 °C
- Sterilize with 2N NaOH or 100% ethanol; autoclaving is not recommended
- All columns are fitted with translucent polypropylene reservoir tops and with bed supports that are permanently mounted in the polypropylene column outlet
- Cap, reservoir and column outlet are made of polypropylene
- Bed support is manufactured from High Density Polyethylene (HDPE) with 20 micron nominal bed support porosity
- Tubing connections are male Luer locks
