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.
Thermoline has a digital centrifuge available. The model THC-16D has a maximum speed of 4000 rpm and a capacity of 16 x 10 mL tubes. A micro haematocrit centrifuge model THHC-24, which has a maximum speed of 12,000 rpm with a 24 tube rotor, is also available.
Hanna microprocessor-based portable turbidity meters provide laboratory-grade accuracy for field or laboratory use. HI93703-11 measures turbidity from 0 to 1000 FTU (NTU). For best accuracy, HI93703-11 measures from 0.00 to 50.00 FTU in steps of 1/100th of FTU. The meter meets ISO 7027 requirements. HI93703-11 is equipped with an infrared LED light source. The infrared LED has a long life and maintains constant emission for the life of the instrument. The wavelength peaks at 890 nm, which provides the required intensity of diffused light even in samples with low turbidity values, and also reduces the interference from colours.
Vented closures are now available for all Nalgene sterile disposable flasks. The vented closures, made of HDPE, feature a 0.2 µm hydrophobic PTFE membrane that provides sterile gas exchange for shaker and suspension cell culture.
Bacto Laboratories is the exclusive Australian agent for Dairei's range of refrigerators and low temperature freezers.
