Variable Volume Pumps

Variable Volume Pumps

A new brochure detailing the range of miniature dispense pumps has now been published. The pumps are available in three types, high and standard performance LPV models, along with LPL solenoid pumps, in a range of full stroke volumes from 50 µL to 3000 µL.

These pumps, which are an ideal alternative to conventional syringe or peristaltic pumps, combine a compact, lightweight design, with low power consumption so they can be located wherever fluidic requirements dictate, regardless of maintenance accessibility.

They are designed for consistent, repeatable performance, with a CV as low as 0.04% at full stroke, volume resolution as small as 0.04 µL. Thanks to the use of chemically inert construction materials, Lee pumps are maintenance-free, providing users with the assurance of a reliable operating life of 5,000,000 cycles minimum.

The range provides engineers with optimum flexibility as the high performance LPV models combine speed, size and accuracy with small dispense volumes from 0.04 up to 1.0 µL and pressures to 95 psi, the standard LPV models offer the same reliable, repeatable performance on a smaller scale, with dispense volumes from 0.01 up to 1.5 µL and pressures to 15 psi, while the LPL solenoid models enable consistent, fixed volume dispensing from 50 up to 130 µL (depending on configuration).

Lee pumps are ideal for a wide range of automated liquid handling applications such as systems for in-vitro diagnostics, scientific instrumentation, drug discovery, or wherever high precision, reliable fluids transfer is needed, on a miniature scale.

Series 300 Micro Inert Valve

Series 300 Micro Inert Valve 

The new Series 300 Micro Inert Valve is a 2 way, normally closed solenoid valve that facilitates higher packing density, enabling more valves to be positioned in the same area, resulting in smaller manifolds and therefore a smaller footprint. The LFN centre-to-centre spacing is 0.3" (compared to 0.5" for the previous LFV valve). These valves can also contribute to savings on material, for example, if engineered plastics such as PEEK, are used for the manifold. Other benefits include less transport volume thanks to closer spacing which results in reduced length of the connection passages in the manifold. This can reduce the amount of reagent needed, whilst also reducing the transport time of a sample. The LFN valve has a low internal volume of just 13 microlitres and so reduces the amount of fluid needed which contributes to lower eagent volume and faster throughput. The LFN valve also features a faster response time (20mS) and a lower power consumption (900W) than the LFV micro inert valve.

Lee HI-BAR Plug

Lee HI-BAR Plug

The Lee HI-BAR Plug is a reliable, leak-tight, threaded plug which has been designed to seal large passageways in hydraulic and fuel system manifolds. Rated for system pressures up to 5000 psi and temperatures from - 65 F to 275 F, Lee HI-BAR Plugs offer many advantages over existing threaded plug designs.

Significant savings are realised in reduced machining, assembly and inspection costs. A drilled and tapped hole is all that is required along with a simple installation tool. Installation is quick and easy and HI-BAR Plugs can be reused several times. The special features of the HI-BAR Plug are; simple installation hole, self-locking feature which eliminates lockwire, elimination of O rings due to the use of the Lee Multi Seal and aluminium and polyamide-imide materials for low weight.

A.F.O. Plug (Axial Force Only)

A.F.O. Plug (Axial Force Only)

The A.F.O. Plug provides a leak-tight, metal to metal seal in high pressure, high temperature manifold applications. Designed to be both removable and reusable, the plugs feature a floating seal that self-aligns to allow for threaded holes that are not concentric with the through hole. As a result of the plugs' two-piece construction, the seal does not rotate during installation, thus preventing galling of the seat. Also, since all the force is contained in the axial direction, the boss diameter can be smaller compared to other designs of plug.

Standard A.F.O. plugs are manufactured from corrosion resistant 303 and 15-5PH stainless steel and do not require O-rings or sealants. They are designed to withstand pressures up to 56,000 psi and temperatures to 600F, when fitted into hard materials and can be used in softer materials as well, such as aluminium or plastic.

The plugs are available in sizes from .190" to .750" with UNF threads, however, depending on specific application requirements, special versions can be supplied. A.F.O. plugs have recently been supplied in Monel in sizes up to 1,325" UNF threads to withstand 15,000 psi working pressure and 22,500 psi proof pressure.

A.F.O. Plugs are typically used in the offshore oil industry where applications include subsea wellhead trees, tubing hangers, completion tools, slick joints and down hole tools.

A range of NACE compliant A.F.O. Plugs made from MP35N is also available. These plugs conform to the requirements of NACE MRO175 / ISO 15156 and offer exceptional resistance to corrosion and sealing performance in high pressure, high temperature applications .
