Enteral Syringes

Cut the end of the syringe. Take care to leave a small flange to prevent the plunger is pushed to the end. This can be done using a hacksaw and a round file. The end of the syringe will probably be flat with a cone nozzle needle is offset to one side.

Cut most of the cones and file the edges until the remaining flange is about 1 mm wide all around. This is not a critical dimension. The syringe is now functional. A useful accessory is a small elastic tether that can be slipped over the wrist to prevent accidental loss.

Collection of small and delicate marine organisms can be facilitated by using a vacuum manifold from a large syringe and a disposable bottle self-closing plastic collection as described in this article.

Buying a large disposable plastic syringe from a pharmacy. The 60ml size is appropriate for many organizations and is readily available.

Buy a plastic jar with screw top of appropriate size to store bodies until they could be decanted.

Use the tip of the syringe and a fine felt tip marker to mark the position of the hole in the lid of the jar. Be careful to put the hole close enough to the coast, but clear of the wire. The reason for this is to leave space for the flap closure spring.

Cut the hole using the tools that you work best. A punch Bell is fast, but may not be available in the ideal size, but the hole can be made to correct the size and shape. If all else fails, a carpet knife will work, cut strawberries and the file is too small to fit reasonably close to the syringe, which should enter the hole easily, but with little clearance all around.

Pierce a pair of small holes near the loading hole for the elastic spring that closes the door. These can be drilled or pierced with a heated wire. These holes should be just beyond the edge of the hole to allow the loading of the syringe to force the valve open when it is inserted into the loading hole.

Pierce some holes in the other side of the cover to let water escape during the transfer of bodies from the syringe into the pot. These holes should be large enough for organisms to escape from them. 1 mm to 2 mm in diameter is usually appropriate. as you find convenient use. A large number of holes allows the transfer to occur more quickly.

Cut a small piece of flat plastic sheet for the flap. It must be rigid enough to remain stable. Drill two holes to correspond with the holes in the elastic spring in the lid. The flap should be straight wall adjacent to the holes and parallel to the line of demarcation between their centers. and should be totally on the hole transfer, but clearly over the edge of the lid.

Thread a short length of thin elastic cord (2 mm) (sling) in the holes in the lid and flap. Attach the ends to hold the flap in place on the underside of the lid. Ensure that the flap allows clearance for the pot screw on the lid.

Testing the function of the flap edge in the steel lid on the pot and inserting the Syring through hole transfer. The component is expected to open in the pot and close automatically when the syringe is removed.
