Manual Fully Half Autoclavable Micro Fixed Pipettor provided by STE-Mart has a digital display function for more accurate volume setting. The control button and tip ejector cover are made of PA material; the main body of the micro pipette is made of high-quality PP material, which is resistant to high temperatures. The pen tip core can be disassembled at 121 degrees and highpressure extinguished. Lightweight handle design, combined with low plunger, tip connection and ejection force, helps reduce the risk of repetitive stress injury (RSI). Easily rotate the piston button to select dispense volume. Every variable pipette is tested to ensure precision and accuracy.
