Profinia Instrument Cooling Accessory
These cooling units allow you to work with temperature-sensitive proteins for sample loading and collection without having to work in a coldroom or use a refrigeration unit. Just fill the accessory with water, and freeze it until it's ready to use. The accessory can maintain precooled samples and fractions at 2–8°C for 5–6 hours at 20°C ambient temperature, with the instrument powered up and operating.
Profinia pH Monitor Kit
This inline pH monitor enables real-time monitoring of pH conditions during a sample run. The monitor is connected via a standard pH probe connector (BCN). The pH monitor kit includes the pH probe, flow cell, and all tubing and accessories required to connect to the Profinia system. pH monitoring is fully supported by the Profinia system and optional Profinia software.
Key features include:
- High-precision calomel electrodes, which ensure full compatibility with buffers such as Tris that are incompatible with Ag/AgCl electrodes
- Reference and pH electrodes that are sealed in a single body, which minimizes drying out of the reference electrode and eliminates the need to add electrolyte solution
- A biocompatible PEEK flow cell with a swept volume of approximately 80 µl, for high precision and accuracy
- pH range of 1–14
Profinia Desalting Sample Loops
Desalting methods are designed for rapid desalting or buffer exchange applications and require that a desalting loop accessory be used in conjunction with a desalting cartridge. A syringe and three-way stopcock combination is used to fill the desalting loop, which is available in 2 and 10 ml sizes. Luer fittings allow easy installation onto the Profinia instrument.
Profinia Sipper Tube Replacement Kit
The sipper tube replacement kit includes ten pieces of precut, 13.5 cm (5.3") long, chemically compatible polypropylene tubing. The sipper tubes are used in the buffer and sample inlet compartments.
Profinia Instrument Accessory Kit
Included with every Profinia instrument, the instrument accessory kit has the necessary plasticware to operate and complete purification runs. The kit includes buffer bottles (125 and 250 ml) with lids, waste and diluent bottles, a cleaning tray, an inline filter pack, and 15 and 50 ml sample tube lids.
Profinia Instrument Inline Filter Pack
The inline filter pack consists of 12 filters and is a necessary part of the Profinia system’s general maintenance regimen. The filters help reduce line clogging and minimize high backpressure. The instrument inline filter should be replaced at regular intervals to keep the system running at its optimal level.
