OHAUS is the broadest single brand Australian Scientific carries, at more than 280 products ranging from a $35 accessory to a $17,393 dual-range analytical balance. It is worth knowing the range is not only weighing: alongside the balances sit Frontier centrifuges, hotplate stirrers, overhead stirrers, dry block heaters, incubating shakers and vortex mixers.
The OHAUS range
Analytical and precision balances
The Explorer Series includes dual-range models such as the EX225D at 120 g × 0.01 mg and 220 g × 0.1 mg, precision models up to 12,000 g × 0.1 g, and an Explorer Semi-Micro Series. The Pioneer Series runs from analytical models reading to 0.01 mg, such as the PX225D at 82 g × 0.01 mg and 220 g × 0.1 mg, up to precision balances such as the PX6201/E at 6,200 g × 0.1 g, and the Adventurer Series runs from analytical models at 120 g, 220 g and 320 g × 0.1 mg to precision models such as the AX8201/E at 8,200 g × 0.01 g.
Portable and compact balances
The Compass CX Series and Compass CR Series run from 220 g × 0.1 g to 5,200 g × 1 g, and the Navigator Series, described for laboratory, industrial and education settings, reads from 220 g × 0.01 g to 2,200 g × 0.1 g. See all portable OHAUS balances.
Centrifuges
The Frontier range runs from a $590 mini centrifuge to high-speed micro models: the FC2516 reaches 16,500 rpm (19,080 × g) and the FC5515 reaches 15,200 rpm (21,953 × g), while multi centrifuges such as the FC2706 and FC5707 run at 6,000 to 6,800 rpm. Browse centrifuges, or the more than 40 rotors for the Frontier 5000 Series and Frontier 2000 Series, plus tube adapters.
Hotplates and stirrers
Hotplates and hotplate stirrers cover 15 L to 22 L capacities at maximum temperatures from 360 °C to 550 °C, with stirring to 1,600 or 1,800 rpm, available as units or as kits with a temperature probe. Overhead stirrers and their accessories are listed at capacities of 25 L, 40 L and 100 L.
Heating, shaking and mixing
Dry block heaters are available as 1, 2, 4 and 6 block models in analogue and digital versions, alongside incubating shakers, including a thermal shaker that cools to 17 °C below ambient, and vortex mixers in fixed-speed, analogue and digital models.
Frequently asked questions
How do the OHAUS balance series compare?
Explorer includes dual-range analytical models reading to 0.01 mg and precision models from 0.001 g to 0.1 g, up to 12,000 g. Pioneer runs from analytical models reading to 0.01 mg up to precision models of 6,200 g × 0.1 g. Adventurer runs from analytical models at 0.1 mg (120 g to 320 g) to precision models of 0.001 g to 0.1 g, up to 8,200 g. Compass reads 0.1 g and 1 g from 220 g to 5,200 g, and Navigator reads 0.01 g and 0.1 g from 220 g to 2,200 g.
Do OHAUS centrifuges come with a rotor?
The FC2516, FC5513 and FC5515 micro centrifuges include a rotor; the FC2516’s is a 24 × 1.5 ml or 2 ml rotor. More than 40 rotors are listed for the Frontier 5000 and 2000 Series, along with tube adapters. Check the individual product listing for what is included before ordering a rotor separately.
What speed and g-force do the Frontier centrifuges reach?
It depends on the class. High-speed micro centrifuges reach 16,500 rpm and 19,080 × g (FC2516) or 15,200 rpm and 21,953 × g (FC5515). Multi centrifuges such as the FC2706 and FC5707 run at 6,000 to 6,800 rpm and 3,660 to 4,445 × g, the Multi-Pro FC5714 reaches 14,000 rpm and 18,624 × g, and the mini centrifuge reaches 6,000 rpm at 2,000 × g.
What is the difference between a hotplate and a hotplate stirrer?
OHAUS lists hotplates, which heat, and hotplate stirrers, which also stir at up to 1,600 or 1,800 rpm. Capacities run from 15 L to 22 L and maximum temperatures from 360 °C to 550 °C. Some are sold as kits with a temperature probe and holder.
What readability do OHAUS analytical balances offer?
Analytical models read to 0.01 mg (the dual-range Explorer and Pioneer models and the PX85) or 0.1 mg (the 120 g to 320 g Explorer, Pioneer and Adventurer models). Precision models read from 0.001 g to 0.1 g, such as the PX223 at 220 g × 0.001 g. On dual-range models the finer readability applies up to the lower capacity, for example 120 g × 0.01 mg and 220 g × 0.1 mg on the EX225D.
Is OHAUS only a balance brand?
No. Of the more than 280 OHAUS products listed here, about a quarter are in the balance and scale categories. The rest include centrifuges and more than 40 rotors, hotplates and stirrers, overhead stirrers, dry block heaters, shakers, vortex mixers and accessories.
