We used a Digiflex TP automatic pipettor
to aspirate 0.25 mL serum that was dispensed with 4.75 mL Tris-HCL buffer (0.05 mol/L, pH 7.5, 0.25% vol/vol Triton X-100) into clean, 8-mL screwcap vials, then mixed it on a hematology mixer.
Two new pipettors
were delivered, free of charge, in a few days.
Pathlength/volume calibration curves were prepared using single-channel pipettors
to dispense defined volumes of reagent into microplate wells.
Workbench with hood and UV radiator (see Sections 1.1.4 and 3.2.2) and positive-displacement pipettors
or regular pipettors
in conjunction with aerosol-proof disposable pipette tips.
combine researcher-requested features with the latest ergonomic principles to provide enhanced performance.
The Vision electronic pipettors
line has full-color screens and unique touch wheel interfaces.
* MLine pipettors
feature a comfortable ergonomic design: Extremely low plunger forces; easy tip ejection; smooth and secure volume setting mechanism; small volume increments and full autoclavability.
The system features new software wizards with pre-set, validated methods and allows the use of one or two pipettors
.16 draw liquid into the tip of these pipettors
, a partial vacuum is created when the pipette plunger moves tip and down the pipette piston.
, which are hand-held liquid handlers, are included in this need for easy-to-use laboratory equipment.
At the present time, Martrix offers the PlateMate automated pipetting systems and Speedmation single- and multi-channel manual and electronic pipettors
. Robbins Scientific offers the Hydra automated dispensing machines and hybridization incubators.
Because DMSO has distinct physical properties, it behaves differently from water when handled by air-displacement pipettors
and acoustic droplet ejectors.
