  Miniature Inert Solenoid Valve Protects Sensitive Fluids

Rapid and precise dispensing of aggressive and sensitive fluids is a critical requirement in many OEM applications and miniature component specialists LEE PRODUCTS have an outstanding reputation for developing solenoid valves which excel in these situations.

Lee-LFY2 ValveTheir LFY2 Chemically Inert Solenoid Valve is a good example of this as a recent addition to their field-proven Y-Valve range. This 3-way inert, zero-dead volume solenoid valve features an innovative ‘Y’ internal flow design that reduces the internal volume to a total of just 12 micro-litres.  This design also provides a clean, flushable flow path which reduces, or eliminates carry over between fluids and helps to protect fragile samples.  In addition...

 

  Robust, Lightweight PEEK Safety Screens

Protecting sensitive components in critical fluids handling applications such as those occurring in the medical, scientific and aerospace industries is essential for safety and optimum performance. 

Lee PEEK HiBar ScreensWhile critical components are often relatively immune to low levels of small size contaminants, a single large particle can cause blockages, resulting in system failure and down-time.  Miniature component specialists LEE PRODUCTS offers a complete range of flange mount, HI-BAR® Safety Screens which now includes options made entirely from PEEK (Poly-EtherEtherKetone). This high performance engineering thermoplastic provides excellent...

 

  Miniature, Chemically Inert Stepper Dispense Pump

A miniature, chemically inert Stepper Dispense Pump which is designed to deliver variable micro-litre volumes in the 50µL to 250µL range with a consistent performance yet in the most compact package, has been introduced by LEE PRODUCTS.

lee LDP pumpsThe LPD Series pump has been developed to offer greater design flexibility and significant cost-savings to the medical and scientific industries as a result of its maintenance-free design. It can be located wherever fluidic requirements dictate, regardless of maintenance accessibility. The pump is offered in both standard and high performance models, with the latter incorporating a home sensor, encoder and backlash compensation for more demanding applications and provides a CV of ≤ 0.01% at...

 

  Miniature VHS Solenoid Play Significant Role in the Viability of 3D Bio-Printing of Human Cells

The rapid development of viable inkjet technology for highly specialised applications, such as printing human cells, continues to generate significant interest.

LeeCellPrinterIf successful, the realisation of this technology for specialised biological applications, generally known as ‘biofabrication’, has the potential to replace the long established (and often controversial) process of using animals for testing new drugs. However, there are many challenges to overcome to enable the successful production of a valve-based cell printer for the formation of human embryonic stem cell spheroid aggregates. For example, printing techniques need to be...

 

  Plug-In, 2 Port HDI Solenoid Valve is Lighter and Smaller

A new ultra-miniature, high density interface (HDI) solenoid valve for OEM, laboratory, scientific and medical device applications is the latest example of excellence in miniature engineering from LEE PRODUCTS. 

Lee 2port HDI manifold plug in

This new ‘plug-in’ style valve features a 2-port normally closed design and offers similar performance characteristics to Lee’s traditional 3-port HDI design, but in a smaller, lighter package. The constant demands placed upon designers and machine builders to produce reliable and innovative products which are smaller and lighter are being met, thanks in part, to the Lee Companies’ ability to continue to redefine miniature fluidics....

  Hard Seat Micro-Dispense Valve Handles Aggressive Fluids

A new Hard Seat VHS Micro-Dispense Valve which offers precise, repeatable, non-contact dispensing of fluids in the nanolitre to microlitre range, is a recent addition to LEE PRODUCTS established range of VHS solenoid valves

Hard Seat VHSThis option features a precision Zirconia ball and seat instead of a traditional elastomeric seal which ensures resistance to aggressive fluids such as DMSO (Dimethyl Sulfoxide). These, and other ‘aggressive fluids’, would normally attack the ‘standard’ elastomer type materials used in other types of less durable micro-dispense valves. The Hard Seat VHS valve’s small size and weight (45.2mm max length, 5.6mm diameter and 10 grams) means it can be fitted directly over 96 well plates. The valve is designed for 2-way, normally closed operation and the wetted materials comprise stainless steel, PEEK and Zirconia...
