Sticky mats on an orbital shaker: 3 best practices for safe agitation

Orbital shaker sticky mats: stay within limits

Orbital shaker sticky mats work best when speed and load stay within specification. Therefore, do not use the mat above 250 RPM. Moreover, the maximum is a 4 L flask with 2 L of liquid at 250 RPM. This keeps vessels stable during continuous agitation. Use multiple vessels only if each one is fully adhered. Use the mat between 0 °C and 40 °C. Higher temperatures reduce adhesion and can cause drift. For broader configurations, see Shaking and Mixing.

Orbital shaker sticky mats: clean weekly for adhesion

Weekly cleaning is the most important factor for reliable sticking. Clean the mat and platform at least once per week, or before reattaching. First use a general glass cleaner to remove oils and fingerprints. Then rinse with 70% ethanol or 70% isopropanol to remove residues. Afterwards, ensure both surfaces are completely dry, because wet surfaces are slippery. Dust, dirt, oil, and fingerprints can block adhesion and risk spills. For continuity, align procedures with service and maintenance.

Attach vessels correctly with press and twist

Correct attachment is essential for safe agitation. Press each vessel firmly onto the mat first. Then ensure the entire bottom surface is sealed and flat. Next apply a gentle clockwise twist to lock the vessel in place. This reduces micro-slippage during acceleration changes. However, do not remove vessels by pulling straight up. Tip the vessel slightly, then pull to the same side.

Flexible layouts with cut-to-size mats

Sticky mats support mixed vessel shapes and sizes on one platform. The 23 cm square mats can be cut to fit your platform. They can also sit next to standard clamps for hybrid layouts. This is useful when one vessel needs extra mechanical retention. Therefore, plan layouts per run and verify contact surfaces. For application guidance, visit Shakers and mixers for laboratories. Finally, schedule checks through preventive maintenance.
