Approaches to reduce flow pulsation on peristaltic pumps and working principles

Peristaltic pumps inherit with flow pulsation as a natural result of the way in which the pump operates by compressing the tubing.   There are several approaches that can be used to reduce flow pulsation in peristaltic pumps.  The principles behind these approaches to reducing flow pulsation in peristaltic pumps involve minimizing the amount of disruption to the flow of the fluid and allowing the fluid to pass through the pump smoothly and evenly.  A few commonly used methods are discussed herein. 

Vacuum Pump Selection Guide, Use Tips and their Applications

A vacuum pump is a mechanical device that is used to create a vacuum by removing gas molecules from a sealed volume in order to create vacuum. There are several types of vacuum pumps available, each with its own set of features and capabilities. Some common types of vacuum pumps include: rotary vane pumps, diaphragm pumps, piston pumps, scroll umps and diffusion pumps. 

Ultrasonic Cell Homogenizer Working Principle and Their Applications

Ultrasonic cell homogenizers use high frequency sound waves to disrupt and homogenize cells and tissue samples. They work by generating sound waves in the ultrasonic range (typically 20 kHz to 1 MHz) and directing them through a probe or horn that is placed in contact with the sample. The sound waves cause the cells or tissue to vibrate rapidly, which breaks them down into smaller pieces. This process is known as cavitation.  

NIR spectroscopy principle and selection guidelines

NIR (near-infrared) spectroscopy is a type of spectroscopic technique that uses light in the near-infrared region of the electromagnetic spectrum (wavelengths from approximately 750 nm to 2500 nm) to identify and analyze chemical compounds. NIR spectroscopy is based on the absorption of light by molecules. When a molecule absorbs a photon of light, the energy of the photon is transferred to the molecule, causing it to vibrate or rotate. The specific vibrations or rotations that a molecule undergoes depend on the chemical bonds and functional groups present in the molecule. By measuring the absorption of light at specific wavelengths, it is possible to determine the functional groups and chemical bonds present in a sample, and thus identify the chemical compounds that are present.

Peristaltic pump selection guide and tips, applications

A peristaltic pump is a type of mechanical pump that uses rotating rollers to compress and move a flexible tube or hose, which creates suction and propels the liquid or fluid contained in the hose. This type of pump is commonly used in a variety of industries due to its ability to handle delicate and viscous fluids, as well as its ability to operate in a variety of conditions and environments.  

Selection Guide of Electric Rotary Valve in Precision Fluidics

A multi-channel electric rotary valve is a type of valve that is used to control the flow of fluids in precision fluidic systems. It is typically used in applications where precise control of fluid flow is required, such as in the manufacturing of semiconductors or the analysis of biological samples.  The basic principle of a rotary valve is that it uses a rotor with multiple channels or openings to control the flow of fluid through a system. The rotor is mounted on a shaft and can be rotated to align the channels with inlet and outlet ports in the valve body. When the channels are aligned with the inlet and outlet ports, fluid can flow through the valve. When the channels are not aligned with the inlet and outlet ports, the flow of fluid is blocked.

Glove Box Selection Guidelines

A glove box is a sealed container that is designed to allow operators to perform tasks in a controlled environment without direct contact with the materials inside. Glove boxes are commonly used in a variety of applications, including handling hazardous materials, conducting experiments in a sterile environment, and working with sensitive equipment.   When selecting a glove box, there are several factors to consider. These include the size and shape of the box, the materials used in its construction, the type of gloves and other protective equipment included with the box, and the specific features and accessories that are available.   

Application of FLUORINATED oil FLUO-OIL 135 Used in Droplet-Based Microfluidics

Fluorinated oils have received increasing interest over the last few years, as applications in the field of microfluidics have largely expanded. Especially, droplet-based microfluidic platforms have successfully been developed for a wide range of applications such as macromolecular engineering, drug screening, digital PCR or cell encapsulation and sorting, to name a few. Droplets are also widely used as microreactors for chemical or biological reactions as they allow running thousands of experiments in parallel while minimizing costs and volumes in a time-effective manner. 

For all these applications, the compartmentalization into droplets requires a fluid that is immiscible with water and a surfactant to prevent droplets from merging. By far, the preferred fluids for such applications are fluorocarbon oils. They are inodorous, transparent, and they exhibit great retention of reagents in droplets since most organic compounds are insoluble in fluorinated oils. 

Electric Rotary or Selector Valve Application Examples

Electric rotary or selector valve is a stepper motor driven fluid handling valve designed for automated fluidics applications.   The precise rotary valve provides automated routing of fluidic volumes for aggressive fluids.  We offer a cost-effective solution to build your fluid handling module in the instrument design or laboratory experiments.  6-way, 8-way, 10-way, 12-way and 16-way electric rotary valves are available for order.  With small dead volumes and accurate positioning systems, they are widely used in analytical instruments. A variety of typical applications are included but not limited to.
