Does the SB-12L Shaking Water Bath have a minimum fill volume?

Yes. There is a minimum fill line which is approximately 7 cm from the bottom of the chamber. Given the dimensions of the chamber, this equates to about 2.25 liters.


Can I use flasks with the SB-12L? Does it have a platform upon which to affix flask clamps?

Yes, you can use certain flasks, but there is no mechanism by which to use flask clamps. The SB-12L shakes the frame that springs are attached to. It is intended primarily for sealed, capped vessels, such as centrifuge tubes or media bottles.


Does the SB-12L Shaking Water Bath have a drain?

No, it does not have a drain.


Are the springs in the included spring platform adjustable or removable in order to accommodate larger or differently shaped vessels?

Yes, the springs can be removed or adjusted. The platform itself can also be removed by unscrewing it off on the left and right hand sides.
