QLA Basket Shafts
QLA Basket shafts are manufactured from electropolished, 316 stainless steel. Clip on style and O-ring style shafts are available for most dissolution Instruments. O-ring style shafts comply with original equipment manufacturers dimensional specifications and are guaranteed to properly interface with the designated dissolution basket and spindle. Clip on style shafts utilize a proprietary, spring tempered clip, which retains the original gripping tension far longer than conventional shafts. Clip on style shafts comply with USP (711) and original equipment manufacturers dimensional specifications. Both clip style and O-ring style shafts are precisely manufactured to limit rotational wobble to levels far below USP (711) specifications.
- All shafts are constructed from type 316 electropolished stainless steel
- All basket shafts are laser marked with a unique serial number and come with a Certificate of Conformance (COC)
Spring Clips - The USP standard dissolution basket is designed to attach to the basket shaft using spring clips. Over time these clips can lose strength and fail to grip the basket securely. Baskets that are not gripped securely are likely to exhibit excessive wobble. Only QLA clips are made from special spring tempered 316 stainless steel. Competitors’ clips are made from annealed 316 stainless steel. Spring tempered 316 stainless steel clips will maintain its gripping strength much longer than annealed 316 stainless steel clips.
O-Ring - The clipless basket fastens to the shaft using an O-ring instead of clips. While it can be argued that this design reduces wobble and is easier to use, the USP still specifies the use of clips and proof of equivalence may be required if a clipless alternative is to be used.
Care & Maintenance
Shaft Storage - Bent or scratched shafts fail to comply with USP regulations so it is essential not to store shafts on a desk or loose in a drawer where damage or corrosion can occur. Proper storage in a basket shaft/paddle holder can prevent damage from occurring.
Wobble - A Wobble Meter (WOBMET-MI) is available to monitor basket shaft wobble.
