Calibration is automatic. Accuracy is ±0.7%; reproducibility is ±.1%. Fully autoclavable to 121°C. Closed circuit air purging system eliminates air and bubbles from Dispenser without loss of reagent. A turn of the operations selector activates a guard valve to prevent dripping and accidental discharge when dispenser is not in use—no need for discharge tube caps. Integrated swivel neck allows discharge tube to turn a full 360°. Patented direct displacement PTFE resin piston fully displaces reagent with each stroke. For added safety, the dispensing cylinder has a transparent plastic coating. A locking rocker switch and sprocket guide make volume adjustments quick, accurate and easy. Excellent compatibility—suitable for most reagents (except HF). Choose from three sizes.
