53 Pumps, Valves & Liquid Handling Next Generation Miniature Solenoid Valve Combines High Flow, Low Power and Long Life
A new generation of versatile and innovative 3-port solenoid valves which offer the combination of high flow rates, low leakage and low power consumption in a miniature 10mm package have been introduced by miniature component specialists The Lee Company. The novel genvi™ solenoid valve has been designed and manufactured using innovative techniques and represents a range of valves which provide outstanding application versatility and unmatched reliability at an economical price point.
One of the key objectives in developing the genvi solenoid valve was to challenge the limitations of current fluidic technologies by allowing designers to use a miniature, low power solenoid valve, without compromising system-level flow rate requirements.
As a result the valve is capable of achieving minimum flow rates of 30 to 40 SLPM at 15 psid and its spike and hold profile results in ultra-low power consumption (318mW) during continuous duty operation on air and compatible gas applications. Crucially, this reduces system-level heating and improves battery life making it ideal for applications with challenging power budgets.
In addition to high flow, low power consumption, minimal leakage and extended life of at least 25 million cycles, genvi valves are designed to provide response times of less than 10 ms in applications with an operating temperature range from 40ºF to 120ºF.
Typical applications for the valves include molecular diagnostics, oxygen delivery, environmental monitors, compression therapy, breath analysers or wherever high flow and low power cannot be sacrificed for size and reliability.

New Easy-to-Operate Peristaltic Pump
Handheld Electronic Pipette Reduces 96 or 384 Well Plate Preparation Time by 80%
Anima Biotech, based in Tel Aviv, Israel, is using Integra’s VIAFLO 96/384 handheld electronic pipette to study protein translation in the drive to tackle undruggable targets in diseases such as fibrosis, respiratory syncytial virus, oncology and Huntington’s disease. The VIAFLO 96/384’s ability to simultaneously transfer liquids into every well of a multi-well plate has increased the speed of pipetting, improved throughput and enhanced the accuracy of the process.
Principal PSM Technology Scientist Dr Wissam Mansour explained: “We’ve had the VIAFLO 96/384 for about two and a half years now, and find it fast, robust and easy to operate. It’s very user friendly and a big help for our work. During the early stages of assay development, and later on in the hit validation and the hit-to-lead phases, we work with small numbers of microplates. In the past, this was done manually using an 8 or 12 channel pipette, a tedious and time consuming process that required multiple transfers.
The purpose of a peristaltic pump is to pump fluids from A to B. This type of pump has been used for many years in a wide range of analytical devices to pump samples or reagents into the device.
Increasing automation in the laboratory has led to a demand for easy-to-operate pumping systems that do not require pressure to be set individually. In the new EasyClick pump from Spetec the tube is placed in a compact unit that can simply be clicked into place. A spring mechanism automatically adjusts the pressure applied as the tube wears.
By means of the tube, peristaltic pumps are suitable for continuous operation of liquids. Hence, the fluid does not come into contact with moving parts.
Depending on the size of the pump head a peristaltic pump can be fitted with one to five channels. For low-pulsation and continuous pumping a high number of rollers is required. Quantities ranging from µL/min to L/min can be pumped in line with the size of the pump head and the tube diameter.
Spetec’s in-house design department adapts the pump to match customer needs.

The VIAFLO 96/384 allows us to transfer samples and reagents into a 384 well plate in one step, reducing the preparation time per plate by 80% and increasing the throughput considerably. The ability to process an entire plate in one go has also significantly improved the accuracy and reproducibility of pipetting; there is no human hand that can manually pipette into a 384 well plate with the same accuracy as the VIAFLO 96/384.”
