This is an excellent assortment of some of the most commonly used Poly Labware items. Kit consists of 20 items shipped in a convenient storage box. Personally, we use Poly Labware for almost all our work. The only time we resort to glassware is when heating is required. The Poly Labware containers pour better, and are certainly less expensive... not to mention unbreakable. They are ideal for field work where glassware is too fragile to be used or transported.

Set Includes:
One 100 ml Beaker
One 250 ml Beaker
Three Plastic Test Tubes
One 10 ml Graduated Cylinder
One 100 ml Graduated Cylinder
Four Reagent Bottles
One Drop Dispenser Bottle
One 65mm Poly Funnels
Six Pipettes
One Poly Wash Bottle

Polypropylene Labware Set: $20.00

This is a set of 5 top-quality laboratory Polypropylene Beakers.
For general use ( where heating is not required ), we always prefer using Poly Beakers. Their sharper lip allows a more accurate pour, and low cost coupled with their unbreakable nature makes them perfect for most applications. Includes one each of the following sizes: 50 ml, 100 ml, 250 ml, 500 ml, and 1000 ml.

5 piece Polypropylene Beaker Set: $12.00

Test Tubes, in the most common size: 15mm x 150mm. Like all our glassware, they are fabricated
from top quality heat resistant Borosilicate (Pyrex-type) glass. Perfect for all laboratory uses. They use size #00 rubber stoppers.

Test Tubes (box of 12): $6.00

This is the most popular size porcelain mortar and pestle.
Fabricated from "tough as nails" high quality porcelain, this set can take quite a bit of abuse. It is 100mm (4"), glazed outside and rough inside for efficient grinding and features a footed bottom for stability and pouring lip. The pestle is oversized for hand comfort and is unglazed on the bottom. Rims and outside of mortars are glazed with non-lead based glaze. Aside from general laboratory purposes, this is great for grinding powders, herbs or medicines.

4" Mortar & Pestle set: $15.00

12" lengths of 5mm (outside diameter) flint glass tubing.
This is the proper size tubing for fitting the holes in rubber stoppers.

The proper way to cut and bend glass tubing can be found by Clicking Here.
This tubing is also ideal for those who like to make glass sculptures.
Easily melt & form into any shape desired with a propane torch.

5mm Glass Tubing (pack of 6): $3.00

This is a beautiful set of five glass Barnes Dropper Bottles in a nicely polished Teakwood tray.

Our Vacuum Filtering Flask is basically a 500 ml Erlenmeyer Flask with a vacuum port on one side.
The port accepts hose with a 3/8" inside diameter.
Normally used for vacuum filtration (see our Vacuum Filtration kit below), but can also be used for a wide variety of other specialized applications. Made from high quality heat resistant Borosilicate glass.
The Vacuum Filtering Flask has a much heavier wall and rim than a standard Erlenmeyer flask making it extremely strong & durable. Uses a #7 Rubber Stopper.
Note: We also offer a Vacuum Filtering Flask complete with a vacuum pump, funnel & hose.
See our Laboratory Equipment page.

500 ml Vacuum Filtering Flask: $15.00
