  • Temperature controlled (5-95˚C) sample dock.
  • Up to 24 unique reagents or rinses.
  • Windows laptop computer control for fast, easy protocol creation, modification, and storage.
  • Example protocols included.
  • Flat, low deck enables convenient in-hood installation or ventilated enclosure also available.
  • Expandable for future applications.


The Prepmaster 5100 offers a wide range of applications for TEM, SEM and LM including, but not limited to, tissue/biopsies (1mm dia. @ 1-3mm thickness), cells-seeded-on-coverslips and resin-embedded histology samples.

Example Protocols

The Prepmaster 5100 computer controller comes pre-loaded with example protocols for standard tissue preparation (e.g., kidney) that can be run or easily modified. For example, protocols for kidney tissue prep with and without en-bloc UA staining can be easily created and stored.


The Prepmaster 5100 is a smart robot with all the advantages of internet connectivity. Remote access technical support is available.

Computer Controller

The Prepmaster 5100 computer controller comes pre-loaded with example protocols for standard tissue processing (e.g., kidney) that can be run out of the box or easily modified to add/remove steps or extend incubation times for tissues that require longer incubations.  An unlimited number of protocols can be saved. For example, protocols for kidney tissue processing with and without en-bloc UA.  A pre-installation interview will provide our Applications Scientist a list of tissues or cells to be prepared on the Prepmaster and then a protocol will be ready at installation to ensure a smooth transition.

Being a smart system, remote monitoring and control allows for real-time online assistance for methods development and troubleshooting.

Protocol design/validation and protocol execution are distinct user interfaces enabling 100% confidence in validated protocol use compliance. The Protocol Developer is responsible for methods performance, robustness, and validity. The Robot Operator is limited to selecting the method and starting the run.

Future software upgrades will include seamless connectivity to the EMPIAR database with the ability to download and run verified protocols that have been entered into the Sample Preparation Widget along with images generated using said protocol.dable for future applications.

Heated Agitation Station™

For accelerated, enhanced tissue preparation.

Because penetration of osmium tetroxide or other post-fixatives into biological specimens can be slow and may result in uneven fixation, gentle agitation enables uniform post-staining. The Prepmaster's heated (RT-60°C)

Agitation Station ensures that the osmium tetroxide/fixative saturates the specimen evenly, allowing for more uniform and reliable fixation. Agitation increases contact between the fixative and the tissue which enhances the fixation process and reduces the overall fixation time. Heating the specimen often creates conditions optimal to the post-staining process by improving penetration of fixatives and stains leading to more uniform results with enhanced contrast in imaging and reduced elapsed time.

Thermally-Controlled Reagent Reservoir

For temperature regulation of samples and reagents.

With a Hot (RT-60°C) 12-position reagent reservoir and a Cold (5°C-RT) 12-position reagent reservoir, the Prepmaster 5100 enables researchers to optimize staining protocols by controlling the temperature of up to 12 reagents each. Thermal control helps maintain the integrity of the specimens leading to pristine ultrastructure. Often protocols require specimens to be incubated at low temperatures to enhance dehydration, and also require high temperatures in other steps to create conditions critical to the post-staining process. Heating a sample can enhance penetration of fixatives and stains, leading to more uniform results, enhanced contrast in imaging, and reduced elapsed time. Cooling a specimen can minimize swelling or shrinking. The Prepmaster provides temperature regulation over both samples and reagents for complete control and optimization.
