## Questions & Answers

**Q: Does anyone have expereince and know the max size beaker this can fit?  100ml, 150ml, 250ml, or 400ml?**
A: The width of the fully opened prongs is about 9.4 cm, so it should fit up to 400 ml and possibly even 600 ml Pyrex beaker.

**Q: what is the maximum diameter (clearance) of the rod where the head can fit?**
A: 15mm diameter

**Q: How long is it?  How short can it be adjusted to?**
A: It is a fixed length  so you will need to adjust your set up. Measure from the plate w/flat screw head to the base of the 3 prongs, there is also a fine ajustment flange screw on the shaft between the 2 points you measured from to start .  Hope it helps. Steve

**Q: How far from the vertical rod is the gripping point? In other words, if grasping a test tube, what is the clearance between it and the vertical rod?**
A: For a test tube and a vertical rod each having a diameter of about 5/8 inch (1.6 cm), the clearance will be approximately 5.4 inches (13.7 cm).
