This blog discusses the measurement of viscoelasticity and compares ElastoSens™ Bio with traditional rheometers. It aims to demonstrate why ElastoSens™ Bio represents a new era in this scientific field.
Understanding Rheometers: The Traditional Path in
Viscoelasticity Measurement
Before we discuss the new ElastoSens™ Bio, let’s first understand the old instruments used in this field: rheometers. Rheometers have been the cornerstone in measuring the rheological properties of materials, especially in the fields of material science, engineering, and manufacturing. Rheometers function by exerting controlled stress or strain on a material. They then measure how the material reacts, allowing for the assessment of its viscosity and elasticity.
Fundamentals of Rheometer Operation
Rheometers operate on the principle of applying shear forces to a sample. Typically, this involves using rotating plates or cones that make direct contact with the sample. The resistance the material offers to this motion gives insights into its viscoelastic properties. However, this method has its drawbacks, especially when dealing with fragile biomaterials or hydrogels. Direct contact can lead to sample deformation or even destruction, making repeated or long-term studies challenging.
Limitations in Flexibility and Application of Rheometers
Rheometers are extremely useful for many materials, but their use in life sciences and biomedical research has limitations. These traditional instruments often find it difficult to test the viscoelastic properties of soft materials and medical devices. This is mainly because they can be destructive and it’s complex to ensure perfect contact with samples while avoiding issues like wall slip. Moreover, these instruments require a high level of expertise to operate and interpret results, often necessitating advanced training.
The ElastoSens™ Bio: Redefining Rheological Testing
Moving away from traditional rotational rheometers, the ElastoSens™ Bio stands out as a breakthrough in viscoelasticity testing. This laboratory instrument, specifically designed to overcome the limitations of traditional rheometers, excels with soft materials and hydrogels.
Contactless Testing: A Leap Forward
One of the standout features of the ElastoSens™ Bio is its contactless technology. Unlike rheometers that apply direct shear forces, the ElastoSens™ Bio induces sample free vibration through a vibrating sample holder. This approach not only preserves the integrity of fragile samples but also enhances the sensitivity and repeatability of measurements. For researchers and scientists, this means being able to conduct non-destructive tests on soft materials and hydrogels, which was a significant challenge with traditional rheometers.
Facilitating Long-term Studies and Repeated Tests
The ElastoSens™ Bio‘s removable sample holders are a valuable feature, especially for long-term studies. Traditional rheometers usually make samples unusable after removal. However, the ElastoSens™ Bio lets you store samples in controlled conditions and reuse them for more tests. This feature is particularly beneficial for studies involving the slow degradation of biomaterials, tissue engineering, or hemostatic agents.
User-Friendly Design and Operation
ElastoSens™ Bio has been crafted keeping in mind the ease of use. It requires minimal training, making it accessible to a broader range of users, including biologists and chemists with little to no background in rheology. This contrasts sharply with traditional rheometers that demand a high level of user expertise and significant training.
Advancements in Photostimulation and Real-Time Analysis
The ElastoSens™ Bio brings forth advanced capabilities in photostimulation, a feature that is only available in some high-end rheometers. This feature allows researchers to observe the effects of UV/visible light on biomaterials in real time, which is crucial for applications like 3D bioprinting and photocrosslinking. The ElastoSens™ Bio offers adjustable light intensity and the ability to combine different wavelengths, providing unparalleled flexibility in experimental design.

Discover the Applications of the ElastoSens™ Bio
Gelatin is a widely used biopolymer for biomaterials because it is processable in water, biocompatible, and can form soft, hydrated networks. However, physical gelatin gels can weaken or melt near physiological temperatures, so covalent crosslinking is commonly used to improve thermal stability and mechanical integrity. X-Pure Gelatin® is a high-quality, pharmaceutical-grade gelatin characterized by stringent purity standards and consistent performance.
Extracellular matrix (ECM) hydrogels are biomaterials derived from native tissues after removal of cellular components through decellularization. The remaining matrix preserves key structural proteins (such as collagens, elastin, fibronectin, and laminin), proteoglycans, and glycosaminoglycans that define the biochemical and architectural identity of the source tissue. ECM is naturally produced by cells in all tissues and provides both mechanical support and biochemical signaling cues.
Superabsorbent polymer (SAP) hydrogels are three-dimensional, crosslinked polymer networks capable of absorbing and retaining extremely large amounts of water—often hundreds to thousands of times their own weight—while remaining insoluble. Their structure is based on hydrophilic polymer chains containing functional groups such as carboxylate, hydroxyl, or amide moieties, which generate strong osmotic driving forces for water uptake.
Polyacrylamide (PAM) hydrogels are synthetic, water-swollen polymer networks formed from acrylamide monomers chemically or physically crosslinked into a three-dimensional structure. Polyacrylamide itself is an organic polymer composed of repeating acrylamide subunits, and when crosslinked in aqueous environments, it forms soft, highly hydrated gels with tissue-like mechanical behavior. PAM hydrogels are entirely synthetic and industrially produced, offering high batch-to-batch reproducibility and tunable properties.
Polymethyl methacrylate (PMMA) is a synthetic, thermoplastic polymer belonging to the acrylic resin family. It is formed by the free-radical polymerization of methyl methacrylate (MMA) monomers, resulting in a linear, amorphous polymer with high optical clarity and structural rigidity. PMMA is entirely industrially produced, with MMA synthesized from petrochemical feedstocks and polymerized using controlled thermal, chemical, or photochemical initiation.
Poly(lactic-co-glycolic acid) (PLGA) is a synthetic, biodegradable aliphatic polyester obtained by the copolymerization of lactic acid and glycolic acid. It is an industrially produced polymer derived from renewable monomers that are metabolized through natural biochemical pathways. PLGA is synthesized primarily via ring-opening polymerization of lactide and glycolide, allowing precise control over molecular weight, copolymer ratio, and end-group chemistry.
