Microdrill – The high speed drill for stereotaxic use

The high speed drill is designed for opening the skull in stereotaxic surgery, to implant electrode, cannula, and microdialysis probes, etc. This drill is easy to handle and operate.

ThermoStar Homeothermic Monitoring System

The ThermoStar Homeothermic Monitoring System is a dual-channel closed-loop temperature controller that maintains stable core body temperature in small laboratory animals during surgery and anesthesia. Using rectal probe feedback to drive a silica gel heating pad, it keeps animals at a precise set temperature between 20–45°C — preventing hypothermia and the physiological variability it causes. Two fully independent channels allow two animals to be monitored and heated simultaneously.

Portable Stereotaxic Instrument for 2 Mice by RWD

Specially designed for experiments with two mice at the same time. Replace the U-frame, enlarge the operating space, more economical and reliable.

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.
