==Mini-Pumps==
From McQuade et al. 2004 PMID: 15582915
:Two treatment groups of six rats received either, lithium 3 mmol/kg/day or saline vehicle. Drug treatments were administered for 28 days as a constant infusion via subcutaneously placed osmotic pumps (Alzet model 2ML4, DURECT Corporation, Cupertino, CA, USA) implanted under halothane anaesthesia. During drug treatment, in addition to tap water, all rats were given access to 0.9% saline to minimize any ionic chemical imbalances resulting from the diuretic properties of lithium. All rats weighed 160–180 g at the time of implantation. The dose of 0.75 meq/day was based on a predicted average weight of 250 g over the course of the 28-day treatment period
From Smith and Amdisen 1981PMID: 6121860
:We attached a minipump (Alzet Model 2001) filled with a solution of LCl (500 mmol litre-1) bilaterally in the cerebroventicles using the procedure of Biswas and Carlsson (1977)...In vitro studies showed the miniumps to release the LiCl solution at a constant rate (1.08 ul h-1) at 37 ° C.
From Bernstein and Goehler 1983
:Osmotic minipumps (Model 2001, Alzet, Alza, Palo Alto, CA) were implanted in the peritoneal cavity of animals under halothane anesthesia. For half of the animals in each diet group ... the minipumps contained 200 ul of a saturated aqueous solution of LiCl (63 g/100 ml). The pumps delivered a relatively constant ip infusion of solution 1 ul per hour) for approximately 9 days.
