The simplified design of our EZ chromatography columns combines reliable column performance with easier use for fast protein liquid chromatography (FPLC) and low-pressure liquid chromatography (LPLC) applications.
The redesigned columns provide improved ergonomics for simpler height adjustment, anti-roll features, improved endpieces for easier assembly, and superior frit placement for even distribution of sample flow. Made from high-quality materials, the system provides optimal chromatography performance through precision borosilicate glass columns for visual clarity, PTFE endpieces and plungers for a secure seal, PEEK threaded ends that won’t chip or break, and dual O-rings to ensure a secure seal.
Our standard EZ columns are designed to suit the majority of standard laboratory chromatography applications, while the EZ SolventPlus columns are designed for maximum chemical compatibility in applications using organic solvents, such as reverse phase chromatography. Both EZ column styles are available in a variety of sizes and multiple fixed or adjustable endpiece configurations.
Microbore columns are designed for applications requiring the smallest bed volumes with resistance to aqueous solutions and most solvents used in liquid chromatography. With fixed, nonadjustable endpieces, microbore columns are ideal for low-pressure or gravity feed systems and are available in a variety of lengths.
Open solvent bottles can allow harmful solvent vapor to escape and chemicals to be spilled. Omnifit bottle and waste caps provide security, accuracy, and dependability to solvent delivery and waste disposal systems. Our caps can be used to support closed systems, making them ideal for mobile phase handling, culture preparation, and anyone aiming to improve solvent supply and waste handling.
The Omnifit Q-Series is a versatile range of solvent caps with the security of threaded fitting nuts to ensure a leak-free, vapor-tight seal for applications that require repeated connection and disconnection.
The anti-twist design ensures no more twisted tubes when the cap is fitted or removed and eliminates the need to disconnect fluid lines before unscrewing the cap. The autoclavable caps utilize a PTFE inner body for superior chemical inertness and reliable seal without the need for additional O-rings.
The Omnifit T-Series is a simplified and versatile range of solvent caps that require no additional fittings for tubing connections. Your tubing is pushed directly through the cap’s luer ports to create a liquid- and vapor-tight seal, while the anti-twist design allows you to keep fluid lines connected before unscrewing the cap. The T-series is ideal for use in vacuum applications.
The Omnifit T-Series waste caps suit a variety of common laboratory waste vessels while utilizing the same anti-twist and fitting-free design found in the T-Series solvent caps. Since waste systems require positive pressure to pump waste, the T-Series waste caps include an additional vent port to allow for pressure equalization. In order to control vapor released from vent ports, additional precautions are required during use, such as placing the system in a fume hood, installing lur plugs into unused ports, and connecting the OmniFit Vapor Trap.
Traps and filters are needed to ensure the safety of both your instrumentation and operating environment. A variety of bubble traps, vapor traps, and filters are easily integrated into your system to protect you and your equipment.
Omnifit bubble traps enable effective, in-line removal of bubbles from aqueous solutions with or without vacuum assistance. Despite using degassing solvents, dissolved gases can form damaging bubbles in pumps and detectors. Located between the reservoir and the pump, the Omnifit bubble traps force bubbles through a microporous hydrophobic membrane to avoid damaging sensitive fluid components. The Omnifit traps and is available in standard or high-flow designs.
Vapor traps enable you to isolate any solvent vapor escaping from your system during pressure venting without the need to place the system into a fume hood. The activated carbon within the component confines vapors to prevent egress into the laboratory. An indicator strip on the component provides a simple color-changing indicator to indicate when the vapor trap is saturated. When the strip turns red, it’s time to replace your vapor trap.
Media filtration is needed to ensure solvents are free from particulate matter. A variety of filtration options are available, including both reservoir and in-line systems.
Reservoir filters and bubblers are simple and effective solvent filtration solutions. The Omnifit reservoir filters are ideal for applications using harsh chemicals. These bottom-of-bottle filters are constructed entirely from PTFE with slots designed in the body to minimize waste by removing virtually all liquid from the bottle.
In-line filters protect sensitive instrumentation, such as solenoid valves, from damage. These highly inert, microporous filters are ideal for applications involving aggressive and high-purity fluids. A distribution pattern machined onto both sides of the filter housing ensures that liquid is spread across the entire filter to ensure maximum usage of the filter area. With easy in-line installation and simple replacement, these filters are available with both 20 µm and 50 µm porosity.
