Edwards' in-house manufacturing division has available the low-cost QikSpin personal microcentrifuge made in Australia. The centrifuge's maximum speed is 6000 rpm producing 2000 rcf. Two interchangeable rotors are supplied with each unit to accommodate 16 x 0.2 mL and 8 x 0.5/1.5 mL microcentrifuge tubes.
Edwards has expanded its range of in-house moulded laboratory products with the addition of a polypropylene 100 place freezer storage box with hinged lid for tubes up to 2 mL. The hinged lid allows for easier handling and security and can be used in a range of freezers down to -80°C.
The HI221 and HI223 pH meters compare the characteristics of the pH electrode from one calibration to the next. The Calibration Check feature alerts the user if parameters are not suitable for an accurate calibration.
