Micropipetting jig for 6-well plate

Using a micropipette takes a lot of hand-eye coordination. A jig or guide was developed for a 6-well plate to place the micropipette tip in the right location at the center of a well plate and limit the depth of the tip to prevent touching the bottom of the well plate. Two holes for the micropipette tip were created for each well – one for dispensing liquid directly vertical and another one at an angle for withdrawing liquid. The jig is dogeared at one corner to aid persons that are BVI with orientation.

Coverslip holder for culture wellplates

This holder was developed to place and dip a typical size glass coverslip into a 6-well culture plate. The coverslip is used to plate culture cells so they can be removed from the well plate for simpler microscopical observation. The standard procedure is to use forceps to hold the edge of the coverslip when placing and removing from the well plate. This procedure is difficult for both sighted and BVI users.

Flask lid

This device can be fitted onto any standard 250 mL (ID: 28 mm, OD: 35 mm) sized Erlenmeyer flask. It will avoid spillage while also maintaining a constant steady flow when pouring. The lid causes the liquid to flow about 1.8 times slower than a flask without the lid. When 3-D printing, a 109% increase in size is recommended for the lid to fit perfectly on the flask.

Beaker top

This lid will fit on any standard sized 250 mL (ID: 65 mm, OD: 70 mm) beaker. It can be used to avoid spillage while also maintaining a constant steady flow when pouring. The small slit in the lid is for a rubber band. This rubber band can be used as traction to keep the lid from falling off. A flat rubber band with an approximate 76 mm diameter works best.
