rom storage to shipping, it is important to monitor the temperature of your products to ensure they are being stored in optimal conditions. Quick to set up, simple to use, the HI148 Thermologgers are ideal for monitoring temperature in applications such as food processing, transportation, museums and horticulture. Made for dynamic environments An included wall cradle allows for easy installation in almost any setting. The included AAA batteries provide up to two years of use and the IP67 casing protects against dust and water intrusion from any direction. A large clear LCD displays your real-time measurement, so you are always in the know. Sensors where you need them Four models of the HI148 Thermologgers
are available to meet your individual testing needs. Models are available with one or two channels, featuring an internal and/or external sensor. Stress-free measurements Programmable high and low alarm LEDs flash if temperatures exceed the user-selectable setpoint, warning you if something needs adjusting. The LED is easily visible from a distance. Detailed temperature profile The HI148 Series Waterproof Thermologgers automatically log your results with programmable logging intervals from one second to 24 hours for one-channel models, and from two seconds to 24 hours for twochannel model. The thermologgers feature extensive memory capacity: 16 000 samples for one-channel models and 8 000 samples/ channel for two-channel models. Storing temperature at logging interval, or min or max temperature between logging intervals.
Versatility when you need it

or scientists and professionals who require precision in the field or on the production floor, the HI98199 is a versatile meter that can monitor pH, EC and DO when paired with the respective probe. It is the measurement-specific option you want with the rugged construction you need to give you years of flawless field data. Increased traceability Ensure that your data can be trusted with GLP data. Accessible through the menu, this data includes date, time, buffers/standards used for calibration, and slope characteristics of the last calibration. Versatile data logging The HI98199 allows you to store up to 45 000
Eppendorf conical tubes 25ml

he new conical tube format of 25ml, developed by the inventor of the ‘Eppi’ tube, will advance the world of conical tubes. Working with sample volumes between 15ml and 25ml - often used in bacterial/microorganism culture as well as during purification of plasmid DNA/ biomolecules - in cell culture or during assay preparation, leaves no option to researchers but to work with a traditional high-volume tube like the 50ml conical tube. In recognition of this fact, Eppendorf has developed the Eppendorf Conical Cube 25ml - available with either
Easy data handling The HI92148 application software (required) supports communication between the logger and a PC running Windows OS through a USB-C cable. Using the programme, data acquisition parameters are user selectable and logged data can be downloaded and stored via USB cable.

the new, patented SnapTec cap or with screw cap. These conical tubes have the same diameter as conventional 50ml conical tubes but a ~20% lower height. This allows space-saving storage, for example in freezers. Additionally, the consumption of valuable raw material is reduced by 26% for the screw cap 25ml conical tube and by 20% for the SnapTec cap 25ml conical tube, compared to a conventional 50ml tube. Proportionally, laboratory waste of conical tubes will therefore also be reduced. The wide opening, combined with the lower height, offers easy sample access. When working with low-volume pipettes and tips, the risk of cross-contamination
continuous or log-on-demand samples with logging intervals from one second to three hours. Dedicated ‘help’ key Clear tutorial messages and directions are available on-screen to quickly and easily guide you through setup and calibration. Superior field usability An IP67-rated, waterproof meter means that bad weather, splashes and dust won’t stop you from taking important measurements. The HI98199 is built to withstand immersion in water of 1m for up to 30 minutes. A large display and backlight feature ensure that all of your important information is easily visible, no matter the amount of light. Universal port The ultra-versatile USB-C port integrates seamless transfer of data. There is no need for software - simply connect a USB-C and send your data as a .csv to a memory stick,

Premium raw materials, without the use of plasticisers and biocides during manufacturing, ensure highest sample integrity and optimal sample and pellet visibility. The most innovative feature is the patented SnapTec cap, which is unique within the conical tubes market. This cap is firmly connected to the tube. No need to put the cap on the bench, running the risk
computer or android device. Quick Connect digital probe autosensor recognition The Quick Connect fitting is designed for quick and easy installation of the probes. A watertight connection without threads make attaching and removing the probe simple. The probe and meter automatically recognise the sensors, making it easy to change electrodes. Each probe transmits readings digitally to the meter, where data points can be displayed and logged. Hanna’s pH probe is included with the HI98199 and the EC and DO probes can be ordered separately.

that caps from different tubes may become mixed up or contaminated. The SnapTec cap allows single-handed opening and closing for quick liquid extraction or addition of sample. This is particularly advantageous in multistep lab protocols. Of course, the Eppendorf conical tubes 25ml are directly deployable. Straightforward integration into the existing laboratory environment is ensured. Concurrently, Eppendorf provides a full system of components. Adapters for both tube variants to be used in centrifugation rotors for 50ml conical tubes are available, as well as adapters for Eppendorf ThermoMixer C and Thermostat C, tube holder for Eppendorf MixMate, storage box, tube rack and single tube stand. www.eppendorf.com/25mL
