Product Information
02.09 Laboratory items
Connectors and Adaptors 02.10.2008

All PTFE body
Autoclavable
For use with tube outside diameters of 1 – 11 mm

The Omnifit range of connectors is a versatile system for connecting different types of tubing instantly, including stainless steel, PTFE, glass and silicone. Tubing sizes between 1 and 11 mm can be connected using either Viton ‘O’-rings or PTFE cones. Configurations include 2, 3, 4, 6 and 8-way options.

Fitting Systems 02.10.2008

A chemically inert flangeless fitting with permanently attached PTFE ferrule ideal for repeat connect/disconnect

Pressure rated up to 1000psi (69 bar)
For 1/16”, 1/8” or 3/16” OD semi-rigid tubing e.g. PTFE, ETFE, FEP
For flat-bottom 1/4”-28 UNF, M6 or 5/16”-24 UNF ports

02.09.01 Laboratory items made of glass
Chromatography Columns 02.10.2008

Pressure ratings to 1200 psi (80 bar)
Solvent resistant
Fixed or adjustable height
Robust and easy to use

Omnifit’s empty glass columns are the perfect solution for most low and mid-pressure liquid chromatography applications. Available with an adjustable endpiece designed for quick and easy height adjustment, they offer the chromatographer a multipurpose column that can be used again and again for a variety of different applications.

02.09.02 Laboratory items made of plastic
Bottle Caps and Reservoirs 02.10.2008

Positive containment of laboratory chemicals and vapors
Chemically inert wetted parts
Robust and easy to use
Anti-twist design
GL45, GL32 and 38-430 sizes
2, 3 and 4 port caps

Safe, simple and economic liquid containment. Open solvent bottles can allow harmful solvent vapor to escape and chemicals to be spilled. Omnifit bottle caps and accessories help prevent these problems and give you the security of a safe and dependable solvent delivery system.

02.14 Pumps and valves for laboratories
Electric Rotary Valves 02.10.2008

Exceptional chemical resistance
Pressure rating to 500 psi (33 bar)
Optoelectronic encoder
Microprocessor control
RS-232 interface
Custom designs available

Omnifit’s small electrical rotary valves are designed for use with aggressive chemicals or biologically sensitive materials and have an inert, Teflon® body and Kel-F® rotor. Pressure rated to 500 psi (33 bar). Minimal dead volume, bulkhead mountable. 12VDC, 4 watts. Includes control board with control signals for clockwise drive, counter clockwise drive, ‘HOME’ flag and ‘MOTOR ACTIVE’ flag. Bore size is 1.5mm, step time is 200 milliseconds.

Gradient and Flow Selection Valves 02.10.2008

Precise flow characteristics
Compact, robust construction
Minimal dead volume
Fast response time
All PTFE wetted parts; other materials available

Compact valve / manifold configurations
The Bio-Chem Valve flow selection valves are available with three valve sizes, using 0.38 inch, 0.75 inch and 1.00 inch solenoid shell diameters. These sizes correspond to orifice diameters spanning from 0.032 inches to 0.125 inches, covering a broad range of application requirements. For ease of installation, all inlet ports are positioned on the same side of the manifold. The common outlet port is centered between the inlet ports. (Note: in diverting applications, the inlet and outlet ports are reversed.) The compact manifold construction ensures minimal internal volumes.

Inert Relief Valves 02.10.2008

2 Versions
- 075RV – stand-alone, spring loaded
- 075RS – spring loaded with solenoid control (open when energized)
6 Pressure Relief Settings from 20 to 150 psi
Fully Chemically Inert
Chemraz® and PPS Wetted Fluid Path
Minimal Internal Volume
High Cycle Life

The Omnifit 075RV / 075RS relief valve series is ideally suited for use with aggressive and high-purity fluids. Wetted parts consist of the PPS (Ryton) valve body and the Chemraz® diaphragm. Custom body and diaphragm configurations are available from a broad menu of engineered plastics and elastomers, including Teflon®. The unique Bio-Chem Valve diaphragm retention design ensures the most reliable performance and longest life available.

The solenoid operated, normally closed 075RS relief valve provides dual functionality as a solenoid valve with pressure relief function. This provides flow control and the capability to periodically purge the system.

Isolation Valves 02.10.2008

The fluid path in an Isolation Valve is completely isolated from the valve’s solenoid actuation mechanism. The only wetted parts are the valve diaphragm and the valve body – hence the name Isolation Valve.

Inert
For high purity applications and aggressive media handling the fluid path can be made entirely of extremely inert materials such as PTFE – something that can not be done with pinch valves as PTFE tubing would be too hard to pinch.

Our all-PTFE valves are the most chemically inert solution available. We also offer a choice of PEEK and PPS valve bodies as well as a range of diaphragm materials to suit a large variety of mechanical and chemical requirements.

Pinch Valves 02.10.2008

Bio-Chem Valve Pinch Valves feature:

Inertness similar to an isolation valve
Straight, no-clog flow path
A wide range of medical grade, class VI tubing with sizes ranging from 1/32″ I.D. to 1/4″ I.D.
On/Off control
A selector or diverter flow control in 3 way configurations
Dual 2-way and dual 3-way configurations are available in 100P series products

Self-Priming Micro Pumps 02.10.2008

High accuracy dispense settings from 8µl to 250µl
Low power consumption / minimal heat generation
Low internal volume
Positive shut off
High cycle life – up to 20 million dispense cycles
Choice of inert wetted materials
Broad range of dispense settings and flow rates
The diaphragm pumps are factory set for discrete outputs ranging from 8?l to 250?l. The pumps can be cycled at up to 2.0 Hz for the smallest version and 1.6 Hz for the largest version. Flow rates reach up to 25 ml / minute. Depending on the dispense setting, very high accuracy can be achieved with deviations from set-point of less than 1%. For optimal accuracy, the pumps should be used for the transfer of fluids between un-pressurized containers.
