Researcher, University of Bristol

Our lab was interested in purchasing a syringe pump from WPI. The company's support was helpful in identifying the required model and even informed us of model-specific limitations (which were of no concern for our intended use). The overall processing and delivery was exceedingly fast – less tha...

UniVert - Eclipse Ultra-Low Force Sensors

Eclipse Ultra-Low Force Sensor for milliNewtons measurement. Compatible with the UniVert S and UniVert 1kN the Eclipse detects forces as small as 40 µN.

The Eclipse Ultra-Low Force Sensor is a UniVert accessory designed for low-force mechanical testing where signal quality and overload protection matter as much as resolution. Eclipse detects forces as small as 40 µN and supports interchangeable full-scale capacities across the 20 mN to 500mN range, enabling ultra-low force protocols on a benchtop uniaxial platform.

Force detection to 40 µN for low-force mechanical testing
Five different full-scale ranges: 20, 50, 100, 200, 500 mN
10,000% safe overload protection for setup and alignment
Designed for tension and compression workflows with dedicated ultra-low force fixtures
Fully integrated with the CellScale UniVert platform for controlled uniaxial testing
Compatible with: UniVert S, UniVert 1kN

The Eclipse is used for low-force mechanical testing on the UniVert when you need reliable force measurement in the tens of milliNewtons up through tenths of Newtons, including viscoelastic characterization and cyclic mechanical testing at low loads. In many labs, the Eclipse also serves as a stress relaxation testing device when low-load stability and clean force decay curves are required. Use the Eclipse when your target forces are at or above 0.02 N capacity and you want to keep the UniVert workflow. If your protocol requires forces below 0.02 N, the MicroTester is the recommended platform.

What the Eclipse Ultra-Low Force Sensor is For

Many biomaterials and soft constructs fail, slip, or exhibit nonlinear behaviour before a conventional load cell reaches an informative portion of its measurement range. The Eclipse Ultra-Low Force Sensor extends the UniVert into ultra-low force regimes so you can quantify early-stage stiffness, toe-region behaviour, and time-dependent responses without saturating noise or risking overload during sample handling.

Common reasons researchers add Eclipse to the UniVert:

Improve force resolution for delicate specimens where differences are real but small
Reduce measurement artifacts when running viscoelastic characterization at low loads
Enable low-force cyclic mechanical testing without sacrificing control or durability

To order select the required Eclips Ultra Low Force Sensor and the UV-ELFS-K which includes the ultra low force tension grips and ultra low force compression platens.
