An economical and versatile solution for when flexible quantitative sensory testing (QST) is needed: built around our Static Weight Bearing test and its state-of-the-art colour, touchscreen console, the Algokit can include up to 3 additional sensors among our Electronic Von Frey, Rodent Pincher and Small Animal Algometer (SMALGO). With a common control unit and software, it offers a convenient, compact benchtop footprint.

A perfect solution for all your research on analgesia, nociception, inflammation, neuro-pathologies and post-operative pain.

In order to offer an answer to all your requests regarding different situations of pain measurement, Bioseb is proud to present an innovative, complete solution built around our Static Weight Bearing Test and combining up to 3 sensors amoung our Electronic Von Frey, Rodent Pincher and Small animal Algometer, all connected to one unique Control Unit.

Operating principles

Each of our pain threshold measurement instruments is based on a dedicated configuration which is originally stored in the associated console unit. We upgraded our system to save the configuration directly in the sensor devices, which now allows us to use several instruments with one single interface: the Static Weight Bearing Test and its touchscreen, colour console. The "Plug and Play" principle lets you simply switch off the console unit, change the sensor and resume your work.

This AlgoKit solution can be combined with our BIO-CIS software to improve the repeatability of reflex nociceptive tests. Stimulated pain resistance tests are well known to be highly operator-dependent. BIO-CIS, by displaying in real time the force vs time, greatly helps the operator to improve their skills with the instrument and generate an impactful graphic representation of the data.


• Flexible instrument when a quantitative sensory testing (QST) is needed
• Compatible with our BIO-CIS software to improve repeatability in nociceptive testing
• Control unit features a large backlit display
• Statistical functions: mean and standard deviation values for each animal
• Internal memory with up to 100 values
• Runs on battery for more flexibility
Static Weight Bearing Test by Bioseb
Static Weight Bearing Test

The Core of the AlgoKit: our Static Weight Bearing Test

An easy and non pain-inducing solution for assessing the level of discomfort (incapacitance) in the injured paw of a small animal like a rat or a mouse by measuring the Postural Equilibrium – independently of the operator. The static weight bearing instrument is ideal for your research on analagesia and nociception involving rodents: osteo arthrisis, cartilage degeneration, inflammation models, nerve injury models, and much more... Discover the SWB-Touch: now with a brand new touch-screen console!

By continuously measuring the weight borne by each paw, Bioseb's Static Weight Bearing Incapacitance Test allows the objective measurement of spontaneous pain by assessing the postural equilibrium, thus opening research fields not available when using traditional methods (like the Randall & Selitto test), which can only measure nociceptive thresholds and pain sensitivity using experimental nociceptive stimuli.

Available sensors

Electronic Von Frey
A quick solution to determine the mechanical sensitivity threshold in rodents (mice and rats). This precise and easy-to-use electronic instrument is a must-have reference for your research in analgesia, nociception, neuro-pathologies and post-operative pain.

Stimulation is usually applied on the rodent's hind paws. The paw's withdrawal following the mechanical stimulation is recorded as a response to the stimulus.

A fast and accurate algometer based on an instrumented pincher, allowing accurate nociceptive tests to measure mechanical pain threshold on rat or mouse limbs with minimal constraint.

The pressure is applied in the "inter-digital" region, but can also be applied to the tail for rats. The instrument displays the force at which the animal reacts and reports the nociception threshold.

Dedicated to small animals, like mice and rats, Smalgo is a pressure-based analgesimeter designed for easy assessment of sensitivity threshold. It is a must for osteo-arthritis and pain studies.

The operator adjusts the algometer to the thumb and applies a progressive pressure to the relevant location on the animal (usually joints or back), as if he was applying the pressure directly with his own finger.

Dedicated BIO-CIS Software

Dedicated BIO-CIS Software to increase nociceptive tests repeatability
Dedicated BIO-CIS Software
The multi-instrument BIO-CIS Software, by Bioseb, is compatible with all our mechanical allodynia / nociception measurement instruments and allows you to reduce inter-operator variability, which is an issue for these kinds of tests.

BIO-CIS can be used in two different ways with the Electronic Von Frey, Rodent Pincher and Smalgo:

Direct measurement: When a sensor is connected to the BIO-CIS software during stimulation, the software displays the real-time graph of applied force vs time in real-time. Additional features allows the definition of a theoretical ramp (force/time) with upper-lower limits to be followed and displayed during the measurement and curves of a group of measures can be reloaded and displayed simultaneously for a graphical overview. These options greatly help the operator to improve their skills with the instrument and reduce operator-introduced variability and is useful for generating impactful figures.

• Indirect measurement: The control unit embeds an internal memory allowing you to store up to 100 values measured during your experiments. You will then be able to connect the instrument to the BIO-CIS software and transfer all your results to an Excel spreadsheet.
