Photo of Flexible Curve
Flexible Curve bends to any shape. Plot lab results, draw graphs, copy chart recordings, and produce error-free diagrams. Draw perfect curvesÑplot curves and fit points precisely on any graph with ease, using the flexible curve. Bend into any desired shape. Fastest way to draw spectrophotometer, quality control, and standards curves. Adjusts to any shape. A unique raised ledge on one side prevents ink from running underneath the curve, thus eliminating smudges. The other side is flat for pencil drawings.
Photo of Anti-Static StaticAway™ Brushes

Anti-Static Static-Away™ Brush eliminates harmful static. Eliminates the possibility that static will damage sensitive lab work, affect balance results, or harm microchip-driven instruments. Anti-Static Static-Away™ Brush dissipates static while whisking away harmful dust, lint, and dirt from your work environment. New design blends natural hair and synthetic conductive fibers that simply remove static as it cleans. Because it won’t scratch critical surfaces, it’s ideal for cleaning film, slides, optics, cuvettes, balance pans, microscopes, electronics, and computer monitors.

Photo of Control Company Ultra-Clean™ Premium Aluminum Foil

Premium Ultra-Clean™ pure aluminum foil is manufactured specifically for the lab with added strength and puncture resistance. Highly versatile material can withstand extreme heat and cold. Ultra-Clean™ aluminum foil purity helps maintain the integrity of samples. Foil is impermeable to light, oxygen, and water. Premium grade foil eliminates the problems caused by thin, cheap consumer foils which have minute pinholes caused by the production process. The carton has a metal tear-off bar for ease in cutting to size. Unique box flaps prevent the roll from leaving the box.

Photo of Control Company 3133 Counter Pen

Counter-Pen™ is a combination marker and digital counter designed for the lab and plant. Each time a black mark is made with the felt-tipped pen, it automatically sounds a beep, and LCD displays the counts. Use it to count cell growth on petri dishes, inventory parts, and tally samples received. Touch, sound, and count occur simultaneously. Impossible to make an error, even when interrupted—marks hold your place and counter holds your total. Durable ABS plastic unit provides audio/visual counts to 99999 with reset button, on/off switch, and pen cap.
