Cleaning:

The best and easiest way to clean MiTeGen’s tools is to soak them in a bath of a detergent-containing solution. When mounted in MiTeGen base holders, large quantities of mounts can be cleaned at one time.

To remove protein residues, we recommend an enzyme-containing detergent such as Alconox’s Tergazyme or Decon’s Contrex EZ; otherwise, a standard laboratory glassware/plasticware cleaner like Alconox is adequate. We recommend an initial 10 to 15 minute soak, followed by a quick rinse in a bath of water to remove the detergent. The optimal length of the soak needed will be determined by what residual materials are left on the mount or tool (protein, etc.) and how long it has been sinced they were last used. The sooner you clean them after use the easier it will be.

MiTeGen’s Base Holder makes cleaning easy:

•Load your loop-containing bases into the holder.
•Then place the holder into a plastic or glass tub or dish.
•Mix your detergent-containing solution according to the instructions on the detergent box.
•Then pour the detergent into the tub until the level rises to the Fill Line on the base holder.This will ensure that the loop tips are soaked, while keeping the stainless steel part of the bases out of the solution and preventing corrosion.
In the rare case when soaking doesn’t remove deposits, you can use a Medium (M) or Fine (F) paper wick. For easiest handling, cut back from the widest end using a razor blade so that the diameter fits into a 0.7 mm mechanical pencil. Then dip the other end in water, a detergent solution or in isopropanol, and gently stroke the polymer from base to tip.

Handling Do’s and Don’ts:

The microfabricated tips of MiTeGen’s MicroMounts™, MicroLoops™ and other tools are made from the most durable unoriented polymer available, for ultra-low background X-ray scatter. Compared with an oriented fiber like nylon, unoriented polymers can be more easily torn or cut if used improperly. Follow the instructions below to get the maximum life out of our products.

1. Never touch the tips with your hands. Always use our heavy duty tweezers along the pin shaft, not the tip.

 2. Never push the beveled steel pin into the tip against a hard surface.


3. DO: Clean the tips by soaking in detergent while held in a MiTeGen Base Holder.

DO NOT: sonicate for extended times. Sonication for a few minute or so is ok, but sonication for long periods can damage some tips. Using an enzyme-containing detergent, sonication should be unnecessary.


4. DO:Remove stubborn residues using a MiTeGen paper wick

DO NOT: use cotton or foam-tipped swabs. Swabs can catch and tear the polymer.


5. To dry the tips after cleaning, let them air dry. You can briefly dip in isopropanol for faster drying. Avoid blow drying. If the nozzle is placed too close to the tip, the resulting turbulent drag force can damage the tip. Keep the nozzle at least 20 cm away from the tip.
