MEASUREMENT SOLUTIONS FOR BIO SCIENCES

LoliTrack 5 is a fast and intuitive Windows software for 2D and 3D video tracking and behavior analysis of multiple and focal animals based on contrast or background subtraction, i.e., no markers are needed. This major upgraded version features many improvements and additions as well as a much faster performance on regular PCs.

LoliTrack 5 works with most cameras and video file formats and can track organisms of any shape or size in one or multiple arenas. The program includes a video recording and editing tool, graphs, heat maps, and can export video or image files with data overlay or Excel data files with user-defined output.

A unique feature is that LoliTrack 5 can track numerous animals inside a single arena – even if the objects have the same (or different) shape, color and size. It can handle occlusions (e.g. collisions or crossing paths), and applications where animals can hide or move out of view. Any tracking errors are easily identified and corrected, if required. The user can pick out individual animals for tracking and analysis rather than having to track all of them. User-defined time intervals can be omitted or included for tracking.

With two cameras (or files), this software offers 3D video tracking and behavior analysis in focal animals, and export 3D models of trajectories for further visualizing and analyzing in other software.

Other applications include tracking organisms in 24-, 48- or 96-well microtiter plates for fast screening of activity levels or locomotion (e.g. for toxicological or biomedical assays). User-defined treatments can be added to aid statistical analysis.

LoliTrack 5 can identify specific body points (tail, head, midline center, center of gravity) and track these for studying kinematics (tail beat frequency, body oscillations, etc.) or specific behaviors (direction of orientation or movement, turning rate etc.).

A free demo software allows you to test if LoliTrack 5 will work for your application. Alternatively, we offer free analysis and advice if you send us a video clip as we want to make sure that software works for your application too!

Calculated parameters:

• X,Y coordinates for front, back, center of midline, and center of gravity
• Distance moved
• Speed and Velocity
• Acceleration
• Direction of movement
• Direction of orientation
• Bend (e.g. for body oscillations, tail beat frequency etc.)
• Turning rate of movement or orientation
• Active/Inactive time and %
• Inter-Individual Distance (IID)

All the parameters can be calculated for individual animals, for groups of animals (treatments) or for each user-defined zone (e.g. time spend in zone or number of visits to zone).

Easily programmable 3D mini-shaker with orbital 3D rotation, reciprocal 3D motion as well as soft vibrating rocking of the platform. These three motion types can be performed separately, pairwise and in cycles, periodically repeating the sequence of three motion types. Non–slip, temperature resistant, silicone mat located on the shaker platform provides stable position for vessels during shaking.

The shaker can be used in cold rooms or incubators, operating at ambient temperature range +4 °C to +40 °C.

We recommend this shaker for agitating the medium inside the microplate glass plate wells. Use orbital 3D rotation type for maximum effect.

This miniature impeller pump is highly efficient despite the compact and lightweight design allowing for installation into the smallest places. With acetal impeller and inner parts, viton seals, stainless fittings and a solid construction it is made for continous use in hostile environments like marine labs.

Pump flow rate can be adjusted by varying input voltages between 6 VDC and 12 VDC. Further fine tuning can be made by restricting the outlet using flexible tubing and an adjustable clamp or by simply changing tube inner dimensions and thus friction against flow. The pump is quite happy to run even with the outlet completely blocked. Pressure inside the pump will increase; yet load on the drive motor will reduce as flow is reduced.

The pump mounts onto any planar surface with stainless screws and o-rings (both included). We can supply an optional fitting flange with barb hose fittings for 3.2 mm tubing.

The pump is NOT for submerged use.
