Meets AP Science Practices 1, 2, 4, 5, 6, and 7

It's designed for DNA or RNA electrophoresis.

Intermediate hardness and melting point.

For determining the melting point of organic compounds.

Super absorbent pads are designed to absorb and neutralize up to 900 cc of 10% neutral buffered formalin.

Sterile vacuum blood collection BD Vacutainer® tubes are for serum determination

This Promega offers enhanced amplification over conventional Taq DNA polymerases. Supplied with 5X colorless reaction buffer and a 5X green buffer, which both allow for direct loading into agarose gels with no loading dye required. The included 5X green buffer allows you to visualize migration during electrophoresis. Each tube contains 100 U at 5 U/μl. Note: Requires storage at − 20°C.

It is a set of premium quality 1.413 µs/cm conductivity standards and pH 7.01 buffers that are NIST traceable and contained in portable single-use sachets. Each sachet has the lot number and expiration date stamped on it and is made of light block foil ensuring freshness each time one is opened. Hanna's line of conductivity solutions and pH buffers have been specially formulated to have an expiration of 5 years from the date of manufacture for an unopened sachet. This package of calibration sachets are for 20 sachets (10 each) containing 20 ml of solution.

The double junction electrode is ideal for dirty water, heavy metals, sulfides, tris buffers, and organics. The tester also features a pH and temperature readout toggle, automatic temperature compensation, and a replaceable sensor.

Lead Sensor Kit, Material for (25) tests and/or calibrations for measurement of Lead in water, include: 25 sensors and cuvettes, 25 sample tubes with buffer, 25 syringes (1mL), 15 disposable transfer pipettes, analyte standard solution

A stable, neutral fixative used to ensure the long-term preservation of tissues as close to the living state as possible and provide clear, reproducible results.
