Pope Lab Grade Dewars are rated the most efficient glass Dewars in the World!
This superior ranking is due to rigid quality controls in manufacture and a number of outstanding design and manufacturing features.
Efficiency assured by rigid bakeout and evacuation control (evacuated to 10-5 torr or better).
Evacuation tip completely shielded for increased protection.
Weighted bases on all models for stability
No pads between walls on cylindrical Dewars eliminating this heat transfer potential
Supplied stopper (polyethylene) tops off Dewars to minimize evaporation
This 1000mL flask is has a full base with metal handle and a cylindrical wide mouth. The unsilvered glass of 47369-01 allows you to see what happens when you emerge an item into the liquid nitrogen. Features an aluminum housing and sturdy mesh cover to faciliate a firm grip and increased protection. All Pope Lab Grade Dewars are manufactured of borosilicate glass for liquid nitrogen service.

Promega DNA
These high quality DNA Markers were created by digesting specified DNA to completion with one or more restriction enzymes, complete with heat inactivation. The recommended loading for each is 1μl per lane. Used for DNA electrophoresis labs. Note: Perishable. Store frozen. Shipped next day air on ice. A ship date is required.

Lambda DNA
Lambda DNA c1857 Sam7is isolated from infected e.coli strain W3350 and typically used as a molecular weight marker during DNA electrophoresis. Will yield typical patterns when cut with restriction enzymes. Uncut size is 48.5 kb. Note: Storage at -20°C required, ship date required. Available to U.S. customers only.

Lambda DNA/ HindIII Digest
This high quality DNA marker is created by digesting Lambda DNA to completion with Hind III restriction enzyme, complete with heat inactivation. Great for use as a moleduclar weight marker during DNAelectrophoresis, it is supplied with 1ml Blue/Orange 6X loading dye. Recommended loading is 1 μl per well. Note: Storage at -20°C required, ship date required. Available to U.S. customer only.

Complete demonstration for colors and LED properties.

Sturdy support with variable focus.

Teeny but Strong!

With this excellent set of glassware, your students will have everything they need to carry out basic operations in organic laboratory work.

Wards® UV/VIS Spectrophotometer is the perfect solution for your classroom or laboratory when ultraviolet and visible analysis is a must! Built-in software offers wavelength scanning, as well as a large 4-line LCD display that can be read from any angle. The touch buttons make commanding easy and data entry quick and convenient. The menu is task driven and makes your spectrophotometer very user-friendly. A large on-board memory is capable of storing 200 test methods (standard curves) and saving up to 500 test data. Each unit comes standard with both USB and RS-232 data ports for communication. Two optional features make documentation and reporting a snap; optional software for PCs which includes scanning capability. The USB port can be used for both data transfer and software upgrades. The optional Windows® XP based software expands the capabilities of the instrument including Standard Cuvettes, Kinetics, Abs. & %T, DNA/Protein ratio and wavelength scanning. Data can be easily exported to Excel® for further processing, analysis and storage.
