Rail-mounted Rat Stereotaxic Instruments by RWD

Y-axis slide design, longer moving range: ± 100mm. Replace the U-frame, enlarge the operating space, more economical and reliable.

Harvard Apparatus Pump Controller (HAPC)

The Harvard Apparatus Pump Controller (HAPC) is a centralized 7" touchscreen controller for managing 1–4 channels of PHD Ultra™ or Pump 11 Elite™ syringe pumps. Designed for complex multi-pump infusion and withdrawal protocols, the HAPC simplifies coordination of parallel drug delivery, push-pull microdialysis, and automated in vivo infusion studies from a single interface.

Harvard Apparatus PHD Ultra™ Syringe Pump (Infuse/Withdraw)

The Harvard Apparatus PHD Ultra™ (Infuse/Withdraw) is a fully programmable syringe pump delivering flow rates from picoliters per minute to 216 ml/min with a graphical touchscreen and built-in programming wizards. Supporting syringes from 0.5 µl to 140 ml, it is a trusted platform for microfluidics, microdialysis, cell culture perfusion, and in vivo drug delivery research.

Harvard Apparatus Pump 11 Elite™ Syringe Pump (Infuse/Withdraw)

The Harvard Apparatus Pump 11 Elite™ is a compact, high-accuracy syringe pump with a 4.3" color touchscreen delivering flow rates from 1.28 pl/min to 88.28 ml/min at ±0.5% accuracy. Its on-pump method programming, wide syringe range (0.5 µl–60 ml), and RS-485 daisy-chaining capability make it the workhorse infusion pump for mass spectrometry, microfluidics, and in vivo animal research.

Harvard Apparatus Pump 33 DDS™ Dual Drive System Syringe Pump

The Harvard Apparatus Pump 33 DDS™ is a dual-drive syringe pump with two fully independent stepper motors enabling simultaneous bidirectional operation from 1.02 pl/min to 106 ml/min per channel. Purpose-built for push-pull microdialysis and dual-reagent experiments, it eliminates the need for two separate pumps while offering full independent programmability per channel.

Standard Stereotaxic Instruments

The RWD Standard Stereotaxic Instruments deliver 0.1 mm resolution positioning in all three axes, enabling precise brain targeting for rats, mice, and a broad range of small animals. A rigid "U"-shaped frame, dual-lead screws, and interchangeable species adaptors make this the go-to platform for stereotaxic surgery in neuroscience labs worldwide.

Digital Stereotaxic Instruments for mice and rats by RWD

This is an upgraded version of the standard type with a digital display for higher accuracy (10μm).

Harvard Apparatus PHD ULTRA™ CP 4400 Syringe Pump

The Harvard Apparatus PHD ULTRA™ CP 4400 is the first syringe pump to combine constant pressure and constant flow modes in a single unit. Connecting to any 0–10 VDC pressure transducer, it maintains user-set pressure within ±2% — making it uniquely suited for organ perfusion, ocular injections, and pressure-critical microfluidic experiments that demand automatic pressure compensation throughout the run.

Portable Stereotaxic Instrument for Rat by RWD

Instead of a U-frame design, it adopts adaptors to enlarge operating space, and conveniently enable research work on the rat brain.

Harvard Apparatus PHD ULTRA™ Satellite Syringe Pump

The Harvard Apparatus PHD ULTRA™ Satellite expands a standalone PHD ULTRA™ into a fully synchronized multi-channel gradient system — powered and controlled directly via RS-485, with no additional power supply required. Available in standard, push/pull, and high-force configurations, it delivers the same ±0.25% accuracy and 3.06 pl/min to 215.8 ml/min flow range as the host pump, purpose-built for gradient infusion, multi-reagent microfluidics, and push-pull perfusion circuits.

Large Animal Stereotaxic Instruments

RWD Large Animal Stereotaxic Instruments are purpose-built for neuroscience research in cats, dogs, monkeys, and pigs, with an extended ±100 mm Y-axis range and support for up to six manipulator arms. Available in standard (100 μm) and digital (10 μm) resolution variants, these instruments provide the structural rigidity and precision required for complex large-animal surgical workflows.

MRI Stereotaxic Instruments

RWD MRI Stereotaxic Instruments are constructed entirely from non-metallic, MRI-compatible materials, enabling precise stereotaxic head fixation and brain targeting in dogs, monkeys, and pigs directly inside MRI scanners. With ±100 mm Y-axis travel, support for up to six manipulator arms, and a jaw plate fixation system, this platform seamlessly integrates into fMRI and MRI-guided neurosurgery workflows.
