About this item
This adjustable dispenser features a digital readout, and a positive displacement piston ensures complete recovery of the sample.
- Accurate dual-calibration system
- Easy to set and easy to use
- Positive displacement pipetting of any fluid
- Adjustable
- Precision-molded plastic or glass capillary bores
A unique dual-calibration system provides an accuracy and reproducibility of better than ±1%.
Capillary bores are made of glass except for the 100 to 1000 µl volume and 1000 µl volume models, which are made of precision-molded plastic. Users can set whole or fractional microliter volumes.
A cutout in the barrel of the unit permits a visual check for proper insertion of the capillary bore. A calibration mark on each bore allows for a visual check for complete delivery, and a color-coded mark on the bore lines up with the stainless steel plunger when the dispenser is set at full capacity.
Ordering information: The 10 µl unit comes with replacement bores and an Allen wrench. The larger dispensers are supplied with an accessory kit that includes replacement bores, an Allen wrench, replacement fluoropolymer resin plunger tips, a tip-replacement block, tip resizing tools, and a plunger replacement gauge.
