Maestro pump capable of 10 million cycles with up to 99.5 percent accuracy
Boonton, NJ (June 15, 2016) – The new Maestro piston pump from Bio-Chem Fluidics delivers the longest life and best accuracy of any other pump in its category. The pump is capable of 10 million cycles with clean fluids, and 5 million cycles with aggressive or precipitating fluids.
Piston pumps, used in fluidics systems when the dispense accuracy of a diaphragm pump or peristaltic pump is insufficient, are prone to high failure rates. Typically found in IVD and similar low pressure applications, piston pumps generally depend upon a flushed seal chamber to maintain the piston in a wetted environment. Pump failure happens when the seal fails, which historically occurs between 3 to 5 million cycles when working with clean fluids, even less with aggressive fluids.
The cost-effective Maestro piston pump uses an improved design with high tolerance components to deliver an extended lifetime. Rigorous testing has validated the pump’s performance at twice that of similar pumps.
Maestro is capable of moving between 500nL to 5000µL of liquids with up to 99.5 percent accuracy. The pump integrates easily with existing instruments, featuring drop-in replacement with no custom software required to drive Maestro stepper motors.
Maestro also offers a variety of features, such as PEEK piston construction, and can be customized to meet specific application needs.

Highly efficient solenoid valve ensures minimal heat generation
Boonton, NJ (April 27, 2012) – Bio-Chem Fluidics’ new range of 038T Isolation Mini-Valves provides a completely inert, non-metallic path for highly aggressive and/ or high purity fluids. The valves are designed for use in analytical chemistry and clinical diagnostic applications involving extremely low flow rates.
The 038T2B and 038T2S Isolation Mini-Valves from Bio-Chem Fluidics.
The new range of Mini-Valves includes the 038T2B (bottom-ported) and 038T2S (side-ported) normally-closed valves with ¼- 28 UNF threaded ports. 038T Mini-Valves use a custom designed, high efficiency solenoid that consumes only two watts at 12 or 24 VDC for minimal heat generation.
Fluid contact is restricted to the valve body and the flexible diaphragm, both constructed from highly inert polymers, allowing non-contact parts to be sourced economically from standard components. The valves offer bi-directional flow, and are also available in a manifold mount configuration.

Bio-Chem Fluidics’ valves offer lower pressure drop than conventional mixing valves
Boonton, NJ (July 11, 2011) – Delivering unobstructed, inert fluid paths with high flow rates and low dead volumes, Bio-Chem Fluidics offers the RV-Series of Electric Rotary Valves. The series features three different models for easy integration into OEM systems.
Bio-Chem Fluidics’ electric rotary valves for OEM systems.
Designed for applications such as sample collection, loop injection or flow path selection, the series of valves provides a lower pressure drop than conventional solenoid mixing valves. Each model’s ¼”- 28 UNF fluid port connections and flow configurations were designed to match the industry standard most commonly found in existing systems. All valves use a unique PTFE fluid path for maximum compatibility with aggressive solvents.
The RV-Series includes three different models to match customers’ needs. The most basic model, the RV-E, includes only the valve head assembly for use with a system’s preexisting stepper motors. The RV-SN includes its own two-phase, hybrid stepper motor, and the RV-SC features the same stepper motor with an intelligent motor controller and driver.

Reliable valves reduce clogging risk and cost of maintenance
Boonton, NJ (December 20, 2010) – Bio-Chem Fluidics helps original equipment manufacturers (OEMs) address clogging waste lines in clinical diagnostic systems with its solenoid operated pinch valves.
Bio-Chem Fluidics pinch valves improve clinical diagnostic systems.
Many OEMs use the same rocker isolation valves from the core of the diagnostic instrument to control the system’s waste line. While these valves are efficient at handling test sample and reagent flow, the higher flow rates and thicker consistencies of waste fluid often result in clogs. The diagnostic system must then be shut down, requiring expensive maintenance and part replacement to resume operation.
When pinch valves are used in waste lines, both the occurrence and severity of this problem are reduced. Bio-Chem Fluidics’ pinch valves offer less flow restriction, simpler fluid paths, and larger minimum gaps than rocker valves to reduce the likelihood of clogging. Pinch tubing wears in a predictable manner for easy preventive maintenance scheduling, and can easily be replaced by the user without the need for a service technician.
Bio-Chem Fluidics pinch valves have few moving parts for reliable operation. Only the tubing comes in contact with the fluid path, and exterior surfaces can withstand common cleaning agents. There is no need for a complicated manifold block, allowing the valves to be incorporated into existing systems or new designs.

Bio-Chem Fluidics’ compact 150L-Series easily integrates into OEM systems
Boonton, NJ (November 3, 2010) – Bio-Chem Fluidics has expanded its line of Bio-Chem Valve™ solenoid-operated isolation valves to include the high-flow, chemically inert 150L-Series. The new valves are unique in that they provide a chemically inert fluid path through a large orifice, for a higher flow rate than other chemically inert valves.
The new 150-L Series Isolation Valve from Bio-Chem Fluidics.
The 150L-Series of valves is ideal for use in analytical instrumentation, clinical diagnostics and environmental analysis. All wetted parts are constructed from PTFE for maximum compatibility with aggressive solvents. The 150L-Series features a compact design for ease of integration in OEM systems.
All of Bio-Chem Fluidics’ isolation valves use a solenoid actuation mechanism, which is isolated from the fluid path with a flexible diaphragm. This eliminates the need for the solenoid to be made from highly inert materials, reducing the final cost to the customer. The actuation mechanism is rated up to 20 million cycles to ensure a long service life.

Customizable valves suitable for a wide range of applications
Boonton, NJ (May 24, 2010) – Providing low cost, versatile handling of small flows of aggressive or high purity fluids, Bio-Chem Fluidics (BCF) offers its line of Bio-Chem Valve™ Solenoid Operated Isolation Valves.
Bio-Chem Fluidics Isolation Valves provide low cost handling of high purity liquids.
All wetted parts in BCF’s Isolation Valves are constructed from non-metallic, inert materials to eliminate contamination of the fluid stream through the valve. The valves’ solenoid actuation mechanism is “isolated” from the fluid with a flexible diaphragm. This eliminates the need for the solenoid and casing to be made from high-priced, exotic materials, reducing the final cost to the customer.
Valves can be configured for 2-way normally closed, 2-way normally open and 3-way operation, with orifice sizes ranging from 0.032” to 0.156”. Additionally, BCF provides a selection of construction materials (PTFE, PEEK, PPS) and connection types (threaded ports or manifold mountable), allowing customization for many different applications. BCF Isolation Valves’ actuation mechanism is rated up to 20 million cycles to ensure a long service life.
