BASi is a drug development firm providing contract research services and unique products for the pharmaceutical, biotechnology and medical device industries.

DL probes have been designed for both in vivo studies (subcutaneous tissue, peritoneal cavity) in experimental animals and in vitro studies in aqueous solutions (tissue homogenates, cell suspensions, plasma, biological fluids). Although the profile of a DL probe is thicker than other BASi linear probes, it is a stronger probe with more reinforcement at the joint. The DL is a good choice for many in vitro applications, teaching, and first-time users.
Linear microdialysis probes offer a small profile (320 µm OD) and are entirely flexible. Flexible plastic tubing brackets the membrane window. An internal fiber strengthens the probe and extends beyond the probe tubing to aid implantation in a variety of tissues including dermis, muscle, adipose tissue, liver and other organs. As shown in the figure above, the DL probe may be used in a linear approach (A), or folded in half to form a dialysis loop (B). A small slice of plastic tubing can be used to secure the loop (C) with the glue joints staggered to minimize the thickness of the looped probe.
