The Institute for Molecular Systems Engineering and Advanced Materials at Heidelberg University has incorporated DK INFUSETEK's high-performance intelligent syringe pump as an important component into the microfluidic station.ISPLab01 in Microfluidic Station Equipment List at IMSEAMIn 2022, the Institute for Molecular Systems Engineering and Advanced Materials (IMSEAM) was established at Heidelberg University, the oldest university in Germany, founded in 1386.  The mission of the IMSEAM is to create new materials, methods and technologies from synthetic and natural building blocks at the molecular level, considering complete systems from molecule to function. Four research groups and two junior research groups are currently working at IMSEAM on basic principles and applications for materials development, organic electronics, environmental technology and medicine. IMSEAM also offers core facilities in the field of device fabrication and characterization (IMSEAM core Facility), soft (bio) materials characterization and microfluidics for other universities.Core Facility for Microfluidics ResearchMain Equipment in Microfluidic StationMicrofluidics is an emerging field and is finding use in various disciplines. Starting from understanding flow mechanisms, to the generation of synthetic cells with droplet-based microfluidics, continuous flow microfluidics to complex organ-on-a-chip models. The Microfluidic station aims to provide valuable tools to every interested research group at the University. Among the microfluidic related instruments, syringe pump is a fundamental but critical one, it’s one of the most common methods used to transfer medium into the microfluidic chip, and capable of operating with very accurate and precise volumetric flow rates, ranging from milliliters to picoliters.Researcher setting up a microfluidics systemWith a 4.8" touchscreen and user-friendly control system, the pump is incredibly easy to use, and the working status can be monitored intuitively, which enables the researchers to use the pump instantly and save their valuable time. The pump is designed and has been proven to be a super durable and reliable device, which could greatly reduce the time researchers spend on equipment maintenance.ISPLab01 used for transferring polystyrene beadsDuring the research about establishing a novel method to modify microfluidic chips with thermoresponsive hydrogels using two-photon polymerized direct laser writing, which is conducted by Selhuber-Unkel Group, ISPLab01 had been widely used to transfer deionized water, polystyrene beads and cell solution, which again proved how important the syringe pump plays a role in laboratory.References 1.

Suspension, a heterogeneous fluid containing solid particles large enough to settle, with particle size usually between 0.1 μm and 1mm, is a kind of commonly used liquid in various fields like biology, pharmacy, chemistry, and agriculture. Typical applications include: Electrolytes, Electrodes, Pharmaceuticals, Injecting cells, Pesticides, etc. Some applications require precise infusion or spraying of suspensions over a long period of time, or solid particles that are large and prone to precipitation, so the medium needs to be thoroughly stirred in the syringe to maintain uniform distribution of particles in the liquid. For these applications, DK Infusetek has specially launched the MIX60  stirring syringe pump. The MIX60 stirring syringe pump has injection performance similar to ISPLab01, but with the addition of a stirring mechanism and a 10mL glass syringe with a stirrer inside. By the rotation and linear motion of the stirring mechanism, it ensures that the suspension maintains a good mixing state during the infusion process.This syringe pump has several features:1. Stirring can be done at a fixed position or reciprocate along the syringe2. As the amount of liquid in the syringe decreases, it can automatically change the reciprocating distance and provide limit protection3. Up to 20 working steps can be set to achieve step-by-step infusion4. The syringe control system and stirring mechanism can be controlled separately or synchronously, and the stirring speed can be adjusted        to meet different application needs5. Adopting a sturdy and textured aluminum alloy housing, which is elegant and durable If any comments or suggestions about this model, or if you would like to customize a model that can be adapted to other sizes of syringes, please feel free to contact us by sending email to sale@infusetek.com

Due to the diverse needs of our customers for liquids, especially for some industrial users who need to transport liquids containing particles such as graphene and carbon powder, the ordinary PTFE valves will suffer severe wear, resulting in decreased valve performance or even damage. Therefore, DK INFUSETEK has specially developed a new accessory series of Ceramic Alumina Valve.The series of valves includes two types and five models. One is non-distribution valve, and the other is distribution valve; Non-distribution valve have one model of 3-way valve, while distribution valves have four models: 3-way, 4-way, 6-way and 9-way.Ceramic alumina valves mainly features as following:1. The working temperature range is wider, from 0-100℃, especially suitable for high-temperature applications.2. The material is sturdy and has a very long service life. Under normal use, it will hardly be damaged. The valves are available on SP30/60-1A and ASD60 Series, and the 3-Port Non-Distribution Ceramic Valve is even available on CFSP-I, which is a great news for the customers who are interested in using our constant flow pump in coating industry.

For years, there are requirements for high-precision continuous material dosing in the fields of precision spraying, cell culture, drug delivery, chemical synthesis, food additives adding, etc. Numerous pump products are existed in the market, however, each of them has its own problems in the above-mentioned application fields: For the piston pump, every piston movement creates a pulsation; Peristaltic pumps have the same problem, and when the pipes are worn, the flow rate will decrease and won’t be able to keep constant for a long time; Early traditional laboratory syringe pumps were unable to continuously deliver precise and accurate fluids for a long time due to limitations in syringe size; Later, in response to this problem, a bidirectional push-pull injection pump emerged, which solved the problem of unable to continuously transport fluid, but still unable to maintain flow stability for a long time, causing interruptions, especially in certain laboratory application fields, which couldn’t meet the needs of use. In order to meet such market demand and solve user pain points, Constinfuse® Constant Flow Syringe Pump, which is also called CFSP-I pump has been developed by the R&D Team of DK Infusetek. It truly allows the liquid to be delivered stably, accurately and continuously, with a flow rate range for water quality fluids from 0.06 μL/min to 70mL/min, the accuracy is less than ±0.05%, and the maximum pressure can reach 2 Mpa. CFSP-I Constant Flow Syringe Pump helps you achieve for more in your experiments or producing process. Welcome inquiry, and look forward to your feedback so that we could have the opportunity to continuously meet your needs.
