It's a drill press with a rotational tool on the end.
Analysis of amphetamine-induced rotation was performed in automated rotational bowls (AccuScan Instruments) as described previously (Ungerstedt and Arbuthnott, 1970).
The rheological properties of Au-PVA NFs of varied compositions in water were measured using a rotational rheometer (TA instruments, model: AR-1000) of parallel plate geometry, with an upper plate of diameter 40 mm.
Rheological tests were carried out by a stress-controlled rotational rheometer (AR2000EX, TA instruments, USA) with parallel plates (25 mm in diameter) and at the room temperature 25°C.
The flow curve measurements were carried out on whole slurry samples using a rotational rheometer (Kinexus, Malvern Instruments, Malvern, United Kingdom) set at 45°C.
Other, less significant factors include operator experience, rotational speed, and specific instrument sequence.
The animals were placed in a rotometer (San Diego Instruments) and the rotational behavior in response to D-amphetamine (5 mg/kg) was recorded quantitatively for 18 consecutive 5-min periods (90 min total).
Working efficiency has been improved by automating dead-weight actuation and rotational position changes of force measuring instruments.
The basic aspects of two types of rotational viscometers, i.e., shear rate instruments, also known as controlled rate devices, and controlled stress instruments are also discussed.
