    acumen® Cellista
    "The Acumen Cellista is a flexible platform that enables a wide range of fluorescence assays, from common cell/bead counting and total fluorescence measurements to specialized whole organism imaging and 3D cell culture applications. Cellista offers the highly qualitative data of a ~4X imager with the speed of a typical multimode plate reader. Laser excitation and a large depth of field reliably capture even low expression fluorophores without the need to focus on each well. Cellista is less suited for subcellular resolution imaging nor trying to segment confluent cells, though. The images can also be taken as TIFFs and analyzed in other software suites.

    Ease of use: My facility functions as a staff assisted HTS/equipment core, and I find that I am able to train most users to operate the instrument independently within 1-3 hours. The Cellista software package is very powerful yet approachable to end users.

    After Sales Care: TTPLabtech has excellent after-sales care. The customer-vendor relationship continues well beyond the purchase, and the support is fast and efficient. Difficult questions are automatically advanced to the appropriate engineer and answers are quick to follow. TTPLabtech being a UK-based company, I was initially concerned that support is 6 hours ahead, but the US team is excellent and I am now convinced that some of the UK folks are either nocturnal or simply don’t sleep.

    Value for Money: This is a tricky question. The Acumen is immensely valuable in an HTS environment and traffic and demand on the instrument are high and only continue to grow in my facility. It does come with a nontrivial price tag, and there are cheaper (slower) high content scopes on the market. Still, I would definitely recommend the Acumen Cellista for applications benefiting from speed, sensitivity and ease of use."

    PlateLoc Thermal Microplate Sealer
    "This heat sealer is very easy to operate and maintain. The heat sealing allows for a very consistent bond that is durable at our -20C storage temperature. Some considerations are that this instrument requires an external compressor and the heat seal can degrade the well chimney over time. As a result, a stack of ~40 plates that have been sealed 10-20 times may one or two mm shorter than 40 new plates. This can create issues for top stacking robots such as the Twister or Orbitor."
