Photo of Control Company 3096 Flexible Arm Light, Long

Flexible-Arm™ places light exactly where needed. It's ideal for inspection, quality control, electronics, and sample examination. Fingertip bar raises, lowers and pivots the perfectly balanced lamp wherever desired. It moves 360 degrees in three dimensions. The arm smoothly articulates at three points. Spring counterbalance permits smooth and fluid movement with superior stability. Stylish design is geared specifically for the lab. It is engineered with durable metal construction for years of heavy use.

Three available models provide readings for airflow/temperature; airflow/temperature/humidity/dew point; and airflow/temperature/humidity/dew point/barometric pressure. Simple operation eliminates the need to refer to instructions. Designed for intuitive, easy operation by everyone. Tough ABS plastic housing with O- ring seal and membrane keypad keep out dust and dirt, assuring a long life in severe lab or harsh plant environments. HOLD button freezes the reading on the display. High contrast 3/8-inch-high LCD digits are easy to read.

Photo of Control Company Variable-Speed Peristaltic Tubing Pump

Compact, variable-flow, bi-directional, self-priming, peristaltic pumps offer precise flow deliveries. Ideal for use with conductivity flow-thru cells, liquid chromatography, collecting fractions, pH/circulating fluids or buffers in baths, and moving corrosive materials. They provide outstanding flow control and flexibility for transferring and dosing liquids. Fluid contacts only the tubing for contamination-free pumping. Flow rates are from 0.005 milliliters per minute to 600 milliliters per minute.

Photo of Control Company 3416 Traceable® Digital Calipers

Traceable® Calipers make length/diameter measurements three ways—outside, inside, and depth. Digital display models measure to 8-inches (200mm). At the touch of a button units switch from inches to millimeters. Zero button instantly sets unit to zero when jaws are at any position. This permits, without calculations, setting a Floating Zero™ or reference point to read “greater than or less than results with a minus sign displayed”. Ergonomic design precision calipers are ideal for measuring the outside diameter of stoppers, the inside diameter of tubing, and the depth of vials.

Photo of Desi-Vac™ Vacuum Pump Desiccator Containers

Desiccator with a vacuum pump is ideal for drying, preserving, storing, and even shipping samples. Vacuum pump built into the top removes air with manual strokes. Rubber O-ring-sealed cover maintains vacuum. Achieves a vacuum of better than 200 inches of water (15 inches of mercury). A release button on top allows air into the plastic container to remove the lid. Use desiccants to keep material dry—ideal for storing chemicals, powders, sample tissues, and plant sections, and for weighing samples.

Control Company 4367 Traceable® Salinity Pen

Salinity Three units provide for conductivity, conductivity/total dissolved solids, and salinity. Meters fulfill requirements for CAP, ASTM, NCCLS, CLSI, ACS, CLIA, AOAC, EPA, APHA, AWWA, WEF, USGS, USP, ISO, and Federal/State regulations. Simply turn on, insert, and simultaneously read result and temperature. Easiest unit ever designed for routine analysis and quality control. Elimination of operator technique permits everyone in the lab to report identical readings. Tough, chemical-resistant, waterproof ABS plastic housing assures a long life in severe lab or harsh plant environments.

The Culture Vessel System consist of three (3) NALGENE¨ Products and includes a 12L Culture Vessel with Ports; 1/8 HP Overhead Drive BioTech Mixer and a Lower Assembly with 13-1/2-in. shaft (3/8=in. diameter) with 4-in. axial flow glass-filled polypropylene impeller and a 2-1/2" wide polypropylene baffle for excellent top-to-bottom mixing. The BioTech Mixer provides variable speed, programmable speed/duration control, clockwise and counter-clockwise rotation and is specifically designed for maximum efficiency with system components.
Photo of Secador® Desiccator Cabinets
Secador® Desiccator Cabinets have a patented sealed design that assures moisture and dust free storage of humidity sensitive items. Cabinets are molded of co-polyester plastic resistant to staining, crazing and chemical attack and have built-in protection that blocks 99% of UV light. Desiccant can be placed under the bottom shelf or on any shelf. A hygrometer dial in the door allows for easy monitoring of relative humidity. Carrying handles make them easy to relocate. Customized tops and bottoms allow for safely stacking of units.
Photo of Secador® Auto-Desiccator Cabinets
Secador® Auto-Desiccator Cabinets have a built-in patented, electronic dehumidification system that automatically regenerates the desiccant and reduces the relative humidity to about 25% within 8 hours. Cabinets are molded of co-polyester plastic resistant to staining, crazing and chemical attack and have built-in protection that blocks 99% of UV light. A hygrometer dial in the door allows for easy monitoring of relative humidity. Built in modules require 120 VAC (230 VAC available).
Photo of Dry-Keeper™ Auto-Desiccator Cabinet
D1388-1 Vertical Auto-Desiccator Cabinet features a permanent silica gel contained in the control unit. No desiccant tray is needed. The cycle is indicated by a green light for a 4-1/2 hour absorption period, or a red light indicating 1/2-hour regeneration of the silica gel. Dial hygrometer is located in the door. This cabinet will lower relative humidity 30-40%. Exterior dimensions: 12½" W x 15½ D x 20" H. 120 VAC. D1388-2 is the horizontal version with the same features as D1388-1.

The space saving design of the desiccator dome provides maximum interior clearances. They provide an average of 13% greater interior volume than standard hemispherical domes. Clear polycarbonate top and bottom. This strong, shatterproof desiccator will hold a full vacuum (29.9" Hg [759mm]) at room temperature for 24 hours and will remain air tight even if not under vacuum. A polypropylene stopcock with a PTFE TFR plug which turns, allowing a slow, gentle entrance of air preventing unnecessary turbulence and crucible damage.
