BASi Bee Stinger Gastight Syringes
BASi Bee Syringe Drives require gastight syringes with a 60 mm calibration length. Sizes ranging from 10 µL to 2.5 mL are recommended. BASi Bee Stingers are syringes specifically designed for the BASi Bee. They are available in 500 µL, 1.0 mL and 2.5 mL sizes.
The accuracy of delivery over a given time period depends heavily on the syringe size. Always use the smallest possible syringe. This choice must be balanced against the total time planned for the experiment and the desired flow rate. A 500 µL syringe provides better accuracy than a 2.5 mL syringe at any given flow rate. At a rate of 2 µL/min, the 500 µL syringe will limit the duration of the experiment to 4 hours. At a rate of 0.1 µL/min, the interval between syringe refills could stretch to a maximum of 83 hours. Try to keep a variety of syringes on hand and use the smallest size possible. Using the BASi UniSwitch can extend the duration of a perfusion indefinitely. See the BASi UniSwitch for details.
