Liquid Handling Arm (LiHa)

The Liquid Handling arm is the standard pipetting option for Freedom EVO liquid handling workstations, with up to eight channels to offer precise and reliable parallel pipetting. Various fixed and disposable tip options are available to ensure that this flexible liquid arm is suited to a wide range of applications.

The Freedom EVO liquid handling workstations can be fitted with many different combinations of up to three independent robotic arms chosen from the high precision Liquid Handling (LiHa) arm, the Robotic Manipulator (RoMa) arm, the Pick and Place (PnP) arm and the MCA96 or MCA384 multi-channel arms, bringing true parallel processing to your application. For example, using both an independent RoMa arm and the LiHa arm means the pipetting channels of the LiHa can pipette while the RoMa arm simultaneously moves the next piece of labware, ready for subsequent pipetting processes.

The LiHa arm has two, four or eight pipetting tips per arm, each of which can be raised and lowered independently to detect and pipette different liquid levels in parallel maximizing the flexibility of the option. For a higher throughput two LiHa’s can be installed on a Freedom EVO workstation used with up to 16-channels, each arm with 8-channels. The distance between pipetting tips can be adjusted to offer equidistant tip separation of between 9 mm and 38 mm (0.31 in. and 1.15 in.) to suit a variety of labware formats.

Each channel includes automatic liquid level detection using Tecan’s conductive- or pressure-based detection technologies to ensure safe and correct liquid volume transfer over a spectrum of different liquid types.

The LiHa arm can be used with different fixed or disposable tips to allow a broad range of pipetting tasks. Standard fixed tips are precision manufactured in stainless steel with a number of interior and exterior coatings to offer accurate and reliable pipetting with minimal costs. In addition, the LiHa arm is compatible with several series of Tecan’s disposable tips, avoiding any cross contaminations. Specialized fixed and disposable tips are available for various low sample volumes, as well as high density microplate applications (e.g. 1536-well microplates), ensuring to offer the right solution for your laboratory.
