The LFN series valves are compact 7 mm chemically inert diaphragm-style valves with zero dead volume. These normally closed two-way valves accommodate bidirectional flow and utilize contoured internal flow paths designed to achieve complete flushing functionality. These valves feature an extremely low internal volume of 9 µL, a flow capacity of up to 2500 ohms, and low power consumption of 900 mW, providing consistent and reliable switching performance with the smallest possible footprint.

• Analytical Equipment and Devices

The IMH832 series check valve achieves the lowest pressure loss among valves of the same size.

The IEP Series is an inline high-speed dispense valve that exhibits stable performance under 2-way, normal close, high temperature/high pressure conditions. The welded port made of stainless steel is sized to fit standard 1/16 inch inner diameter ferrule compression fittings. This robust Φ6.4mm axial flow valve can achieve rapid response times and generate droplets with a drive frequency of up to 500Hz. The high-speed operation of this valve allows for accurate flow measurement and serves as an alternative to some pressure regulators. Its ability to operate at high temperatures enables precise dispensing and sterilization of viscous fluids. Common applications include the application of electrolytes and waxes, electron microscopy, mass spectrometry, electric propulsion systems for satellites, and ultra-low temperature surgical devices, all of which are used in harsh environments and high pressures. Features: ■ Operating pressure: up to 5.52MpaG ■ Operating temperature: up to 135°C ■ Response time: as fast as 500μs ■ Lightweight: 4.7 grams ■ Low internal volume: 62μL ■ Inert seal materials: EPDM, FFKM

The LHL series valve is a compact 7 mm magnetic latch-controlled solenoid valve characterized by ultra-low power consumption (approximately 5.5 mJ per switch) and low heat dissipation. These valves are ideal for battery-operated applications that flow air or gas, requiring only a momentary pulse of current (10 to 30 milliseconds) to switch and maintain each flow state. Even when maintaining a specific flow state for an extended period, these valves do not consume power, generate heat, or produce electrical noise. Furthermore, the LHL series valves provide reliable bistable switching performance with the smallest possible installation footprint. They are latch-type miniature solenoid valves capable of switching 1.7 million cycles on a single AA battery. Custom-made products are also available based on customer requests.

This is an electromagnetic valve with a minimized pumping volume. * Durability: over 5 million cycles * High chemical resistance options available: FCR and PFE * Zero dead volume structure * Low internal capacity * Good responsiveness with low power consumption

• Analytical Equipment and Devices

The "VHS Series" is a 2-way normal close inline valve designed for high-precision dispensing applications in the range of nanoliters, microliters, and milliliters. With ultra-fast response times, it is ideal for precise fluid adjustments and reproducible droplet dispensing. Due to its small size, the valve can be installed in tight spaces, even directly above well plate arrays. It is provided with integrated precision orifices, nozzles, screens, or MINSTAC connectors for connecting tubes. Each valve is 100% function tested and designed using materials that ensure consistent performance over the long term. Features: ■ High-speed response: minimum 250 μs, maximum 1,200 Hz operation ■ Compact size with a diameter of less than 6 mm ■ Versatile dispensing: from a minimum of 10 nL to a maximum of milliliters ■ Operating pressure: up to 828 kPaG ■ Low internal volume: 30 μL ■ Lifespan of over 250 million cycles ■ Compatibility with common reagents, bodily fluids, and solvents
