Filtration Separation Purification

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.

· Internal diameter of 3 mm

· Column length range between 25-150 mm

· PCTFE endpieces accept 1/4”-28 UNF threaded fittings to connect column in-line

· PCTFE and stainless steel frits provide superior bed support

· FKM/FMP O-rings provide secondary backup seal

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.

· Threaded ports accept standard male 1/4”-28 UNF fittings

· Compatible with GL32, GL38-430, and GL45 bottles

· Available with two, three, or four connection ports

· Optional on/off valves, check valves, and filters to enable closed-system pressure equalization, prevent particulate contamination, and reduce chemical evaporation

· Operating pressures of -10 psi (vacuum sealed) and 20 psi (+ve pressure)

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.

· Compatible with 1/8” OD semirigid tubing such as PTFE, ETFE, and FEP

· Operating pressures of -10 psi (vacuum sealed) and 20 psi (+ve pressure)

· Compatible with GL32, GL38-430, and GL45 bottles

· Available with two, three, or four luer connection ports

· Optional fluorocarbon check valves, on/off valves, and 10-micrometer (µm) PTFE filters

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.

· Compatible with 1/8” OD semirigid tubing such as PTFE, ETFE, and FEP

· Available with three, four, or eight luer connection ports

· Vent port accepts thread 1/4”-28 UNF connections

· Compatible with GL38-430, GL45, GL53B, and GL83B bottles

· Autoclavable materials including a glass-filled, polypropylene outer cap, PTFE inner sealing face, and an EPDM O-ring seals

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.

· Available with PEEK or PVC body construction

· Available to use as stand-alone or with vacuum pump

· Flow rates up to 60 milliliters (mL) per minute

· System-side differential operating pressure of 30 psi

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.

· Simplified saturation status through integrated color indicator

· Compatible with Omnifit T-Series Waste Caps

· Connection to threaded male 1/4”-28 UNF ports

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.

Choose from a variety of filtration options:

· Reservoir Filters: 10 µm porosity filters ensure even the smallest particulates are removed in harsh chemical systems.

· Filter Bubblers: PTFE or stainless steel construction are suitable for sparging and filtration applications.

· In-Line Filters: Optimal filtration for aggressive and high-purity fluids protects sensitive instrumentation.
