MicroRT Tubing Kits

Room temperature screening is especially important in protein crystallography. Roughly 98% of low-temperature data sets collected on structural biology beam lines do not yield diffraction data of sufficient quality to determine a structure. Room temperature measurements are essential to determine whether the cause of poor diffraction is poor as-grown crystal quality, sample damage caused by ligand and/or cryoprotectant soaks, and/or sample damage caused by the flash cooling process itself. Far too much effort is wasted searching for cryoprotection conditions for crystals that are poorly ordered to start with. Far too much synchrotron beam time is wasted on crystals that should have been rejected in home source screening.

The MicroRT™ system provides an extremely cost effective tool for increasing the efficiency of your diffraction pipeline.

Length: Available in 17mm, 21mm, 23mm, and 38mm lengths
Diameter: 0.080" +/- 0.004" (2 +/- 0.1 mm)
Wall Thickness: 0.001" (25 μm)
Material: poly(ethylene terephthalate)
Porosity: Water evaporation rate through wall at 22 °C: roughly 80 micrograms/hour.
Notes: Heat sealed at one end. Optically clear. Some small optical distortion due to small wall thickness variations around the circumference.

• Allows rapid screening of crystals at room temperature, to help maximize the efficiency of your crystallography pipeline.
• Easy sample mounting with little risk of crystal loss or damage.
• Easy collection of both room and low-temperature data from the same sample.
• Easy sample visualization and alignment, especially for small crystals.
• Capillary tubing is easily cut and sealed , and gives significantly less background X-ray scatter than glass capillaries.
• One size capillary fits all , and capillaries are reusable, lowering your cost per measurement.
