This unit literally pumps thermal energy down the drain. As power is applied to the rugged thermo-electric modules, heat is transferred from the cold plate to the heat exchanger. The heat exchanger is maintained at tap water temperature by a hose connection to the 1/4 inch tubing at the rear of the instrument. A flow of one liter of tap water per minute through the heat exchanger is sufficient to carry excess heat down the drain. The unit has a low temperature limit approximately 40^oC below that of the tap water. The unit is recommended for solutions up to 200ml and uses a 3 inch diameter top plate from which heat is extracted at an initial rate of 130 BTU/hr. There is a built-in magnetic stirrer with speed control which, combined with a magnet bar in the solution, will keep your solution at equilibrium. The digital meter controller is very easy to set. Just follow the simple instructions to dial in the desired temperature for your project. The controller will maintain the set point to +/- 0.1^oC accuracy.

Use this economy vibration damping platform to isolate delicate benchtop instruments from vibrations caused by nearby equipment such as pumps, stirrers and blenders. Vibro-Absorber damping mounts at each corner support the 46 pound mass of the platform. The smooth, non-slip neoprene working surface area is 13 1/2" x 11" and easily wipes clean. The shell is made of high impact polystyrene and is filled with a dense aggregate. Weight holding capacity is 24 pounds. Shipping weight - 53lbs. Learn More

Vibrasorb Damping Mounts isolate sensitive analytical balances and other instruments from vibrations caused by nearby equipment such as pumps, stirrers and blenders. Molded of dense black and white terrazzo, this 2 1/2" thick platform is supported on four Vibro-Absorber cushions and neoprene feet and support up to 35 pounds. This unit will absorb vibrations down to 13Hz with a 35 pound load. With lighter loads, the minimum frequency of damping will increase to a value between 16Hz and 25Hz. A polished surface resists scratches and chemical attack. 18" x 22". Shipping weight - 87 lbs. Learn More

Small Vibrasorb Vibration Damping Mount is like the Large Vibrasorb Vibration Damping Mount (sku: LH18386), except that this unit will absorb vibrations down to 16Hz with a 35 pound load. Dimensions: 13 3/4" x 13 3/4". Shipping weight - 42 lbs. Learn More
