Short Protocol (Steps 1-8):
1. Protect your eyes with a pair of laboratory safety glasses.
2. Remove microarray substrate from wash station.
3. Blot off excess wash buffer.
4. Insert the wet substrate into the substrate holder completely.
5. Close the lid and spin for 10 seconds.
6. Remove the dry substrate from the centrifuge and scan or image.
7. Wipe down the inside of the centrifuge dome after use.
8. (Optional)  The centrifuge will also accommodate microfuge tubes.

Complete Protocol (Steps 1-8):
1. Protect your eyes with a pair of laboratory safety glasses. All users must wear eye protection at all times while using the ArrayIt® Brand Microarray High-Speed Centrifuge.  Laboratory goggles that cover the eyes completely are essential. The High-Speed Centrifuge spins at 6,000 rpm and therefore presents a potential safety hazard.  Users may be injured with flying glass or plastic debris if substrates or microarray tubes become dislodged from the rotors during use.  Never move or invert the Centrifuge during use. This electrical devise should never be submerged in liquid of any kind and poses an electric shock hazard if used improperly. Please read the section on “Safety Information” below before using this product!!

2. Remove microarray substrate from wash station (Fig. 2). The ArrayIt® Brand High-Throughput Wash Station and Microarray Wash Station are fully compatible with the High-Speed Centrifuge, as are wash stations made by many other vendors.  Remove the substrate carefully to avoid scratching the surface, and make sure to wear protective gloves (e.g. nitrile) to protect the microarray from hand oils and fingerprints.

3. Blot off excess wash buffer.  Tap the wet microarray substrate on an absorbent laboratory wipe (e.g. cleanroom wipe) to remove excess wash buffer before inserting the substrate into the ArrayIt®  Brand Microarray High-Speed Centrifuge (Fig. 3).  Failure to remove excess wash buffer may impair the operation of the centrifuge or inhibit the drying procedure.

Figure 3. Removing Excess Buffer from Substrate. Prior to inserting the substrate into the ArrayIt® Brand Microarray High-Speed Centrifuge, make sure to remove excess wash buffer by blotting the substrate on an cleanroom wipe.

4. Insert the wet substrate into the substrate holder completely. Open the clear protective dome of the ArrayIt®  Brand Microarray High-Speed Centrifuge and insert the wet substrate into the open end of the substrate holder. The substrate holder has an open end and a closed end. The substrate should slide into place easily if inserted into the open end of the substrate holder (Fig. 4). Make sure the substrate is inserted completely into the substrate holder. A fully inserted substrate will drop down into place, such that the top surface of the substrate is below the top edge of the safety rail (Fig. 5).

Figure 5.
Fully Inserted Microarray Slide Substrate. The ArrayIt® Brand Microarray High-Speed Centrifuge has a safety rail (white arrow) that holds the substrate in place during centrifugation.  A properly inserted glass slide substrate should look like this.

5. Close the lid and spin for 10 seconds. Closing the lid will trigger the ArrayIt® Brand Microarray High-Speed Centrifuge to begin centrifugation automatically. The Centrifuge will reach a terminal speed of ~6,000 rpm in less than 10 seconds. Spin the substrate for 10 seconds to allow complete drying. After ten seconds, press down on the safety latch to terminate centrifugation. Do not open the clear protective dome until the centrifuge has come to a complete stop. Failure to abide by this safety instruction (see “Safety Information” below) may damage the centrifuge, the substrate or result in serious injury to the user. Please follow all safety precautions when using this device!

6. Remove the dry substrate from the centrifuge and scan or image. Substrates can be removed from the Substrate Holder by applying light upward pressure on the underside of the substrate (Fig. 6). Remove the substrate from the Substrate Holder by sliding it out gently.

Figure 6.
Removing Substrate from Substrate Holder.  Use gentle upward pressure to remove the glass substrate from the Substrate Holder of the ArrayIt® Brand Microarray High-Speed Centrifuge. Once upward pressure is applied, the substrate will slide out easily as shown.

7. Wipe down the inside of the centrifuge dome after use. Use a cleanroom wipe to remove residual wash buffer that accumulates during the centrifugation step from the inside surface of the clear protective dome of the ArrayIt® Brand Microarray High-Speed Centrifuge (Fig. 7). Failure to remove residual wash buffer will result in the accumulation of salts, detergents and other wash buffer components that may contaminate substrates in subsequent centrifugation steps.

Wipe Down Centrifuge Dome.  After each use of the ArrayIt®  Brand Microarray High-Speed Centrifuge, make sure to wipe down the inside surface of the clear dome with a lint-free cloth to remove residual wash buffer.

8. (Optional)  The centrifuge will also accommodate microfuge tubes. The ArrayIt®  Brand Microarray High-Speed Centrifuge can also be used to spin microfuge tubes. Remove the Substrate Holder by grabbing the Centrifuge firmly with both hands and pulling the Substrate Holder straight off the spindle (Fig. 8). Make sure to pull the Holder straight back (Fig. 8, white arrow) to prevent bending the spindle or damaging the Substrate Holder.  The Microfuge Tube Rotor can be installed by pressing downward firmly on the Rotor once it is seated on the spindle (Fig. 9). Make sure to grip the Centrifuge firmly with both hands and press the Rotor into place in a straight manner (Fig. 9, white arrow).  Twisting the Rotor may damage the spindle or the Rotor. Microfuge tubes and spin columns such as those provided with the Fluorescent Probe Purification Kit fit easily into the Rotor (Fig. 10). Tube centrifugation is initiated by closing the clear protective dome.  The centrifuge will initiate centrifugation automatically, reaching a speed of 6,000 rpm (2,000 x g) in less than 10 seconds (Fig. 11). Centrifugation is terminated with the black plastic safety latch.  Press downward to stop the Rotor and wait until the Rotor has come to a complete stop before opening the clear protective dome.

Troubleshooting Tips
1. Substrate did not dry completely.

  • Spin longer
  • Make sure to blot dry before spinning

2. Rotor does not spin.

  • Make sure substrate is inserted fully into Substrate Holder
  • Close lid completely
