Product Description
Concentrate small samples down to the last drop. The tapered pear shape funnels liquid into a narrow bottom, so the remaining volume stays deep enough to heat, stir and transfer even when almost everything has been evaporated, which reduces losses of valuable product.
This listing is for Kimble catalog number 608700-0229: KONTES Pear Shaped Boiling Flask, 29/42, 100 mL. Each flask has a heavy wall for strength under vacuum and heat and is made from low extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A. Capacities run from 5 mL to 300 mL, with 14/20, 19/22, 24/40 and 29/42 standard taper joints. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
Key Features
- Pear shape – Concentrates small residues in a narrow bottom.
- Heavy wall – Added strength for vacuum and heating.
- Standard taper joint – Fits common jointed glassware.
- Range of sizes – 5 mL to 300 mL.
