Product Features
Unique Rotating Collector Platform
Many rotating collectors for electrospinning systems are designed with a single motor on one end of the cylinder that drives rotation. In most applications, this configuration is sufficient, but for small-diameter rotating collectors under 5 mm mandrels and wires, it can lead to problematic torsional forces and wobbling during rotation, that affect the quality and homogeneity of the electrospun sample. The LE-100 BioTubing’s rotating collector platform provides dual-ended drive and applies tension to the mandrel to prevent bowing during rotation. This collector platform allows samples up to 1 cm in diameter and 40 cm in length. It has two drill chuck based adapters, allowing the users to use their own mandrels, providing maximum flexibility for sample development. The platform also has a quick-release mounting system. This allows for efficient mandrel exchange and minimizes handling of finished electrospun products, minimizing setup time, allowing the user to maximize production efficiency
Enhanced Sample Deposition and Uniformity
Consistent electrospinning processes require stable electric fields. The LE-100 BioTubing system has an additional electrode that is specifically designed to be used with the unique rotating collector platform when coating thin-diameter mandrels (<5 mm). This additional high-voltage power supply helps control the electric field and direct the fibers or particles toward the collector. This also helps prevent unwanted alignment effects that often occur when electrospinning onto a thin-diameter mandrel.
Exclusive Environmental Control Unit (ECU)
The Fluidnatek Environmental Control Unit (ECU) regulates temperature, humidity, and air flow within the processing chamber. This ensures consistency and reproducibility of electrospinning experiments, especially when working with difficult solutions, sensitive materials, or in varying ambient conditions. The BioTubing system’s ECU allows users to increase or decrease temperature within the range of 18 – 45 °C and relative humidity between 10% and 80%. Once the air is conditioned, it is passed through HEPA filters to ensure ISO-7/Class 10,000 cleanliness and pumped into the processing chamber at controllable flow rates between 90 and 180 m3/h.
Advanced Recipe Option
The programmable sequential multi-step recipe function enables automation of processing parameters (e.g. voltage, needle-to-collector distance, flow rate, drum speed, among many others) as a function of time. Users can conveniently pre-program dozens of experimental steps and load the recipe to initiate a new process all from the touch-screen interface on the instrument. It supports two access levels and allows up to 99 users with individual logins and permissions, ideal for validated processes like ISO or GMP compliance. The recipe function also allows offline recipe programming, enabling users to create and upload recipes remotely from a computer, enhancing flexibility and simplifying process automation.
Automated Emitter Motion
Unlike many electrospinning systems, the LE-100 BioTubing system’s syringe pumps are mounted on the same apparatus as the emitter (needle or spinning head). This allows the needle to traverse across the processing chamber without affecting the solution flow. There are several benefits to this configuration. First, it reduces or eliminates tubing for solution flow, minimizing dead volume and preserving expensive additives like biological samples or active pharmaceutical ingredients. Additionally, by translating the needle, the collector can remain in place, which is especially beneficial when using the rotating drum as the increased stability supports higher rotational speeds. It can also be used in combination with the programmable recipe function to automate the process of fabricating a homogeneous, uniform layer of nanofibers or nanoparticles, targeting a specific area of the collector for precision application of coatings. Lastly, when using the Taylor cone camera, the needle will be in focus at all times during needle translation, allowing you to confirm the process is stable at all times.
Regulatory Compliance and Process Validation
The LE-100 BioTubing can be provided with qualification documentation to support validation compliance, including Factory Acceptance Testing (FAT), Site Acceptance Testing (SAT), Installation Qualification (IQ), and Operational Qualification (OQ). These documents facilitate process validation and comply with standards such as Good Manufacturing Processes (GMP), Good Laboratory Practices (GLP), and Good Automated Manufacturing Practices (GAMP), meeting Food and Drug Administration (FDA) and International Organization for Standardization (ISO) requirements.
Batch-to-Batch Reproducibility
Consistency must be maintained when fabricating medical and pharmaceutical products to ensure standards and specifications are met. The optional High-definition Process Data Hub enables monitoring of all processing parameters and stages throughout the electrospinning process, along with internal signals of the machine. Some valuable datapoints that are captured continuously include temperature, humidity, voltage, flow rate and rotational speed, and needle translation. The system also senses and documents when the door has been opened or any alarm set by the user that has been triggered. This enables the advanced sensors to monitor parameters and for the user to evaluate how a batch has varied if the samples fluctuate post-development.
Versatile Emitter and Collector Options
The LE-100 BioTubing offers versatility through a wide range of compatible materials, solvents, and electrospinning configurations. Researchers have the flexibility to experiment with various materials (polymers, ceramics, metals, additives or their blends), emitters (single-phase, coaxial, triaxial, multi-needle, needle-less, among others), spinning orientations (vertical, angled, horizontal), and collectors (flat plate, drum, mandrel, and dummy collector) to fabricate nanofibers and particles with different properties for numerous applications all in a single integrated electrospinning unit.

High Voltage Options
The LE-100 BioTubing is equipped with four bipolar high voltage supplies, allowing users to operate at voltages from -30 to +30 kV. Two bipolar voltages can be used for two separate needle setups, and the remaining two can be used for the collectors (main collector and dummy collector). These configurations enhance process flexibility for complex material deposition, including proper sample adhesion when coating different samples or substrates. They also allow for the reorganization of functional groups in the material at the molecular level, enabling the processibility of solutions that exhibit longer jets.
