How Guava easyCyte Systems Work

Single, dual, or triple excitation laser configurations provide up to 14 simultaneous detection parameters, including 12 fluorescent colors plus forward and side scatter for size and granularity determination. For applications requiring exceptional sensitivity, a high-power blue laser (HPL) is offered in both single-loader and high-throughput (HT) formats.

Guava easyCyte Instrument Features

easyCyte flow cytometers use novel microcapillary technology in a compact, user-friendly format, which is powerful enough to run your most complex assays. In addition, these simple fluidics enable a self-aligning flow cell that can be removed for cleaning by the user. New, more robust lasers available in virtually any combination mean that you choose the excitation and emission channels that are most relevant to your lab’s experiments. Each of the versatile optical configurations can be equipped with an affordable single-sample loader, or an integrated multi-well sample tray option, enabling worry-free walkaway acquisition of up to 96 samples.


No sheath fluid—direct sampling using the easyCyte patented microcapillary system

All easyCyte Systems use a unique, microcapillary flow cell for easy operation and minimal maintenance.

  • Microcapillary technology allows for direct sampling by aspiration, eliminating the need for sheath fluid (see figure). As a result, the instrument is very compact in size and simple to operate.
  • The flow cell is self-analyzing, and can be easily removed for cleaning—say goodbye to delays during acquisition due to clogged flow cells. This feature makes the easyCyte Systems beneficial for measuring a wide variety of cells and particles.
Guava easyCyte Sheath Fluid

Direct absolute counts without reference beads

Absolute cell counts are a distinct advantage of direct sampling, and automatic cell enumeration is obtained from every sample acquired on an easyCyte cytometer. A positive-displacement syringe pump enables not only direct sampling, but can adjust the flow rate as well to ensure clear data from a range of sample titers.

Sample handling formats for both tubes and 96-well plates

Guava easyCyte HT 4th Generation

Automated sampling for 96-well plates

The easyCyte HT series enables walkaway sample handling and acquisition for higher-throughput assays using a built-in, automated 96-well plate loader tray, which can hold a 96-well plate as well as 10 sample tubes. To ensure that cells stay in suspension during sampling, a rotating, variable-speed mixing paddle with auto-cleaning is used between each well, so there is no need for manual resuspension after loading the plate. This virtually eliminates carryover between samples, and mixes more efficiently than shaking plate holder formats.

Single sample loading for tubes

For manual sample handling in a cost-effective format, we offer the easyCyte Instrument with its rotating sample tube loader. The manual loader holds two separate tubes, allowing the user to progress quickly from one sample to another, or to wash between samples following an acquisition.

Guava easyCyte SL 4th Generation

Compatible with many common fluorochromes and fluorescent reagents

Thoughtful laser and detector selection ensures that easyCyte Instruments are compatible with familiar and trusted fluorophores, as well as many of the newer dyes that offer advantages, such as increased brightness and photostability.

Pre-calibrated instruments that need no adjustment

The performance of every easyCyte instrument has been calibrated and optimized to ensure instrument-to-instrument reproducibility. This means that there is no user-adjustment necessary.

Quality control of daily performance

The Guava® easyCheck™ Kit is used to verify system performance and maintain daily quality control before running any assays, and is superior to instrument calibration for this purpose. The kit consists of easyCheck standardized fluorescent beads and diluent, facilitating the assessment of accurate counting and fluorescence detection. The easyCheck Kit is included with all instruments to enable daily routine signal optimization and quality control.

Guava easyCyte Instrument Performance

The easyCyte format is compact and offers many innovations in optical performance and software.

Precise and accurate absolute cell counting

Guava easyCyte Systems combine microcapillary flow with a precision pump to provide accurate and precise absolute counts—without the use of reference beads. Absolute counts can be done using cellular or bead samples.

Using the ViaCount™ Reagent and module allows for the determination of live, apoptotic, and dead cells. Linear and accurate results can be seen across the multiple concentrations and on a variety of cell and sample types.

Guava easyCyte Precise and Accurate Absolute Cell Counting

8-peak rainbow beads

Spherotech® 8-color beads analyzed on the Guava easyCyte Systems demonstrate the instrument’s proficiency for resolving adjacent fluorophores in multiple detection channels.

8-Peak Rainbow Beads: Green Fluorescence - 488 nm laser
8-Peak Rainbow Beads: Yellow Fluorescence - 488 nm laser
8-Peak Rainbow Beads: Red Fluorescence - 488 nm laser
8-Peak Rainbow Beads: NIR Fluorescence - 488 nm laser
8-Peak Rainbow Beads: Red Fluorescence - 642 nm laser
8-Peak Rainbow Beads: Blue Fluorescence - 405 nm laser

Superior small particle bead detection

The easyCyte Systems have been shown to detect particles as small as 0.2 µm—a significant improvement over typical flow cytometers. This increased resolution and sensitivity allows for better separation, making gating and identification of dim populations easier. These capabilities may prove particularly useful for researchers analyzing particulates, beads, bacteria, and algae. Acquisition of a mixture of beads of known sizes demonstrates the ability of easyCyte Instruments to detect and discriminate particles as small as 0.2 µm.

Superior small particle bead detection

Consistent sample results across an entire plate with sample mixing

To ensure that cells stay in suspension during sampling, a rotating, variable-speed mixing paddle with auto-cleaning is used between each well, eliminating the need for manual resuspension after loading the plate.

Evaluation of well-to-well consistency with sample mixing for a 96-well plate. Sample concentrations were within the acceptable range for all samples within the plate.

Guava easyCheck beads were diluted at 1.0 x 106 cells/mL and placed into all wells of a 96-well plate. The plate was then spun at 150 x g for 5 minutes to mimic settling. Each well was acquired and concentrations were determined. Results show the concentrations for each well (solid line) as well as +/- 10% values (dotted lines).

The mixing feature virtually eliminates carryover between samples and mixes more efficiently than shaking plate holder formats. Data shown below confirms that carryover is minimized with this format.

  Plate 1 Plate 2 Plate 3 Plate 4 Plate 5

Guava InCyte Software heat map and IC50/EC50

Guava InCyte Software HeLa Cells heat map

HeLa cells in microtiter plates were treated with multiple cytotoxic compounds for 24 hours. Cells were stained using Guava MitoDamage, MitoCaspase, or MitoStress kits. Cells were analyzed on the Guava® platform, and percent population data was compared in a heat map format using Guava InCyte Software. InCyte Software allowed for the quick identification of hit compounds, as well as the comparison of all 5 parameters simultaneously as shown in the pie charts above. The figure shows the data for the 80 compounds on both cell lines.

IC50 determination using the Cytochrome c Kit and analyzed with the built-in IC50/EC50 curve-fitting feature of Guava InCyte. Cells were analyzed on the Guava® easyCyte™ 8HT. Plot A shows the drag-and-drop gating strategy used for the IC50 determination. Plot B shows the IC50 curve results for gambogic acid, and Plot C shows the EC50 for etoposide. The once complex task of finding the IC50 or EC50 for a compound is now performed with just a few clicks of your mouse.
