Mini Capsules for Laboratory Mice, Rats & Guinea Pigs

Ideal for materials that are insoluble, form poor suspensions, are affected by excipients or are odorous and distasteful, e.g., sustained release beadlets, paint flakes, chromic oxide marker

For lower GI drug delivery size 9 has been used in rats >200gm & Guinea Pigs; size M has been used in mice >30gm. Capsule holders are available for dip coating in enteric solutions.

Size 9 can be used for intra-colonic delivery via rectal insertion in rats >200-250gm.

Save time and money by eliminating validation of suspension / solution homogeneity.

Eliminate excipients absorption affects.

Automated Blood Sampler

Instech's ABS2™ automates the collection of blood samples from laboratory animals. By eliminating labor-intensive manual withdrawals it can streamline drug metabolism and pharmacokinetics research. It can also reduce the stress on animals caused by handling.  The sampler withdraws blood from a tethered freely-moving animal according to your programmed schedule, stores the samples in an integrated refrigerated fraction collector, and replaces the withdrawn volumes with IV fluid. You control and monitor sampling schedules, volumes and withdrawal rates for up to twelve animals from a single computer. Unique advantages of the Instech blood sampling system include:  Undiluted samples, verified by in-line sensors.  A short collection path, to minimize mixing and collection times  Less than 5 µL of blood wasted per sample, to minimize hemodilution.
