Friction-Drive Test Tube Head
 

Back to the Rugged Rotator page

The friction-drive test tube head is useful for many operation. This aluminum disk is equipped with spring clips to hold test tubes for such operations as blood agitations, isotopic competitive protein binding assays, and similar procedures.
A clutch permits stopping the head to insert and remove tubes without turning off the motor. It attaches easily to any rugged rotator. The spring clips permit the tubes to be inserted radially from the side of the clip rather than the top. This is not only easier to use but less likely to break tubes. The clips are adjustable so the tension can be adjusted to the precise amount preffered for a particualr diameter tube.
SPECIFICATIONS
Anodized aluminum disk size: 14 in. (36cm). The disk is furnished with 31 spring clips to accomodate 10 to 18 mm diameter tubes and 16 spring clips to accommodate 20 to 30mm diameter tubes. Either size or a combination of both may be attached to the disk. Assembly is quick and easy
