The Perfect Laboratory "Assortment" Reach for this LaPine Clamp and you're always right! It is precisely designed to do more clamping jobs for you than any other clamp available. It's die-cast aluminum alloy jaws hold any obj'ect from 0 to 3 H " diameter —fine wires, thermometers, beakers, and even separatory funnels—round or irregularly shaped. This genuinely new LaPine Clamp is made like a fine drafting compass, yet is rugged enough to withstand the severest laboratory conditions indefinitely. Fine adjustment (.09" per turn of screw) provides positive clamping without springs—either gentle clamping or a bulldog grip. Jaws are coated with resilient, chemical- and wear-resistant clear vinyl plastisol to protect glassware. The Yz "-diameter extension rod fits clamp holders or lattice frame clamps. «"*·
