System Overview
Biotage

Selekt is an automated flash purification system
with a built-in QR reader for Biotage Sfär columns, RFID reader
for Selekt racks, UV detector, pump, fraction collector, and
touch screen.
Columns
The system has two column channels. Columns can be placed
both on the right side of the system and on the front (up to 50g);
see Figure 1.

Racks and Vessels
The system collects fractions into a variety of collection racks
and vessels. The following Selekt racks are available:
»
48 positions for 13 x 100 mm tubes
with a vessel volume of 9 mL.
»
35 positions for 16 x 100 mm tubes
with a vessel volume of 14 mL.
»
35 positions for 16 x 150 mm tubes with
a vessel volume of 22 mL.
»
28 positions for 18 x 150 mm tubes with
a vessel volume of 27 mL.
»
15 positions for 25 x 150 mm tubes with
a vessel volume of 45 mL.
»
6 positions for 120 mL flasks.
»
10 positions for 240 mL flasks.
»
8 positions for 480 mL flasks.
The collection bed can either hold a collection tray with up to
three of the racks with vessel volumes up to 120 mL (Figure 3),
or one of the 240 or 480 mL flask racks.
One collection tray is standard, but by extending the fraction
collector, it is possible to use two collection trays at the same
time. The maximum collection volume with no rack change is
3840 mL for standard bed and 7680 mL for extended bed.
RFID Tags
All Selekt racks have an RFID (radio-frequency identification)
tag that can be automatically identified by the system when the
rack is placed on the collection bed.
