BASi HoneyComb Fraction Collector
Use the BASi HoneyComb to refrigerate up to 48 sample vials
during the collection of microdialysates or other fluids. Cooling is accomplished by an efficient internal electronic device which
requires no coolants or external accessories and reaches the preset temperature (4 degrees C) within 20 minutes after powerup. The
standard borosilicate glass autosampler vials used for collection of samples may be capped, open, or arranged in a combination of
sealed or open vials according to the user's preference. The use of 6 x 32 mm autosampler vials facilitates transfer to the Sample
Sentinel Autosampler for LC analysis. Plastic vials may also be utilized in this fashion, but an optional carousel for these taller
vials (6 x 35 mm) is required.
The BASi HoneyComb can collect samples from one or two different sources. One sampling needle assembly is provided with the unit. A second needle can be purchased separately. Vials can be advanced two at a time, when each needle is collected to a separate microdialysis probe. Vials can also be advanced one at a time, when only one probe is being sampled, or when one needle is used to collect and the second needle is used to dispense a reagent prior to, or after collection of the sample.
Simple fraction collection protocols are set via the front panel LCD display and keypad--computers are not required. Protocols may include a preset delay time, collection interval, number of samples, and cooling on/off. The fraction collector may also be controlled via rear panel input when more complex protocols are required. It is also possible to split a dialysis sample stream between collection into a vial in the HoneyComb, and injection directly into an LC system by using the HoneyComb in tandem with the Pollen-8 Online Injector.
