The Go Direct Melt Station accurately determines the melting temperature of solid substances. It connects via Bluetooth® wireless technology or via USB to your device.

Teach students the visual detection capillary method of melting point determination with the Go Direct Melt Station. It accurately measures melting temperatures of a solid (up to 260°C), and the real-time graphing provides a unique perspective of the melting process.

The wide-angle observation and magnification window, LED-lit heater block, and adjustable tilt base give students a clear view of the substance as they witness the state change. Internal cooling fans reduce the waiting time between sample testing. Also included is an important safety feature that automatically powers down the heating block after 60 minutes with no change to the control knob.

The Go Direct Melt Station can be used in a variety of experiments:

• Determine the melting temperature of an known organic solid such as aspirin, ibuprofen, or caffeine.

Description

Minicentrifuge-vortex Microspin FV-2400 is specially designed for genetic engineering research (for PCR–diagnostics experiments). Units can be used in microbiological, biochemical, clinical laboratories and industrial biotechnological laboratories.

Micro–Spin provides simultaneous mixing and separation of samples, using centrifuge and mixing modules, located on the common spin–module.

FV-2400 is an “open type” centrifuge (without lid), that increases the speed of centrifugation and resuspension operations.

Minicentrifuge-vortex Combi–Spin FVL-2400N is specially designed for genetic engineering research (for PCR–diagnostics experiments). Units can be used in microbiological, biochemical, clinical laboratories and industrial biotechnological laboratories.

Combi–Spin provides simultaneous mixing and separation of samples, using centrifuge and mixing modules, located on the common spin–module.

FVL-2400N is provided with protection mechanism that stops the rotor motion when the lid is opened.

Step 1.0 pH units, 100 strips

Min unit 1 pH unit. Roll 4.8m

The concept of chirality can be difficult for students to visualize. Go Direct Polarimeter provides a visual representation of this concept by measuring the optical rotation of optical isomers such as sugars, amino acids, and proteins. The Go Direct Polarimeter is simple to use, includes free, downloadable experiments, and is supported by the free Vernier Instrumental Analysis^® app.

Its unique vertical layout and lack of custom glassware make this polarimeter very student friendly. In addition, the analyzer is automatically rotated by an internal motor giving students more time to understand experiments such as the reaction kinetics of HCl and sucrose. The 589 nm LED makes it ideal for comparing optical rotation values to those in literature, allowing students to calculate specific rotation for sucrose, fructose, and other optically active samples. Students no longer have to determine the optical maximum with their eye—they now have a graph that shows a clear change in the light’s polarization.
