Products - Microarray Tools - Microarray Wash Stations - High-Throughput Wash Stations to Speed and Simplify Blocking, Wash and Rinse Buffer Steps for DNA and Protein Microarrays
ArrayIt® has developed a highly innovative microarray wash station that facilitates microarray processing and washing at an affordable price. Our High-Throughput Wash Stations accommodate up to 25 microarrays in a durable slide rack and 500 ml buffer reservoir equipped with a magnetic stir bar. Compatible with all 25 x 76 mm glass substrate slide microarrays, these wash stations can be used with any magnetic stir plate and are essential equipment for all microarray laboratories. Multiple wash stations containing different buffers simplify and speed microarray processing and washing.

1. Fill the Wash Station with 400 ml buffer. For best results use ArrayIt Microarray Wash Buffers and Blocking Buffers.
2. Place the Wash Station on a magnetic stir plate.
3. Turn on the magnetic stir plate to initiate buffer mixing.
4. Place 1-25 glass microarrays in the black substrate rack.
5. Insert the rack into the Wash Station.
6. Cover the Wash Station with the tight-fitting lid.
7. Mix for 5 min with a wash buffer of choice.
8. Remove lid and substrate rack and empty buffer by inverting the Wash Station.
9. Add a new wash buffer and repeat steps 2-8 as the protocol requires.
10. When wash steps are complete, for best results dry using a microarray centrifuge.
1. Fill the Wash Station with 400 ml buffer. This volume will fill the Wash Station approximately 2/3 full. The Wash Station is designed to be used in aqueous (water-based) buffers, but the acrylic box is resistant to mild solvents such as ethanol and isopropanol. The use of strong solvents such as acetone will discolor the unit and should NOT be used under ANY CIRCUMSTANCES. For best results use ArrayIt Microarray Wash Buffers and Blocking Buffers.Microarray Buffers
2. Place the Wash Station on a magnetic stir plate. The unit should be placed in the center of the unit to avoid a “dancing” stir bar during the mixing process.
3. Turn on the magnetic stir plate to initiate buffer mixing. Choose a mixing speed that provides vigorous agitation without spilling the wash buffer over the top of the Wash Station. The Wash Station is designed for room temperature (20-25°C) washes, but can accommodate buffers pre-cooled to as low as 4°C or pre-heated to warm as 50°C. The Wash Station should NOT be used in freezers, on "hot plates" or in microwave ovens UNDER ANY CIRCUMSTANCES.
4. Place 1-25 glass microarrays in the black substrate rack. The black rack holds any “microscope slide” type substrate (25 mm x 76 mm).
5. Insert the rack into the Wash Station. Make sure the rack is in the center of the Wash Station for best mixing.
6. Cover the Wash Station with the tight-fitting lid. The lid prevents buffer evaporation during mixing and also keeps particulate from falling into the Wash Station during use.
7. Mix for 5 min with a wash buffer of choice. Buffers could include various dilutions of SSC, SSPE, SDS, TritonX-100, NP-40, ethanol, sodium borohydride or any other aqueous buffer that is used in conjunction with DNA or protein microarrays. The acrylic Wash Station is not stable to strong acids or bases or solvents such as acetone. DO NOT use improper buffers in this unit UNDER ANY CIRCUMSTANCES.
8. Remove lid and substrate rack and empty buffer by inverting the Wash Station. The retention screen will prevent the stir bar from falling out of the unit. Aqueous buffers can be discarded into a standard laboratory sink fitted with a proper drain.
9. Add a new wash buffer and repeat steps 2-8 as the protocol requires. This allows new buffers to be used for protocols that contain multiple wash steps. Several Wash Stations can be set up in tandem for increased throughput.
10. When wash steps are complete, for best results dry using a microarray centrifuge.
1. No buffer mixing
- Check the stir plate power cord
- Make sure the mixing switch is turned on
2. Poor buffer mixing
- Make sure the Wash Station is in the center of the stir plate
- Check that the buffer volume is 400 ml
3. Uneven microarray signals
- Increase wash time
- Increase rate of buffer mixing
4. Buffer evaporation
