## Overview

The Laboy Glass 100mL Pear-Shaped Schlenk Flask is an essential tool for air-sensitive chemistry, featuring a high vacuum valve and durable borosilicate glass construction. Designed for seamless integration with other lab equipment, this flask ensures precision and reliability in your experiments, backed by a 102-day money-back guarantee.

## Description

This standard schlenk flask is a round bottom, pear-shaped flask with a ground glass joint and a side arm,which has a 0-4mm high vacuum valve to control the flask's exposure to a vacuum manifold for a schlenk line.The glass out joint at top is used to add material in the flask and can be stopped by a ground glass stopper.when the flask is connected with a vacuum manilfold under a positive pressure of inert gas, the stopper can be replaced with other apparatus, for example a reflux condenser. Laboy glass flasks are heavy wall designed,made by hand-blowing to ensure uniform wall thickness, made of high-quality borosilicate glasss and annealed at 800 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling.

## Features

- DESIGN----This Kjeldahl shape schlenk flask consists of a pear-shaped flask facilitates heating and stirring.It has a sidearm fitted with high vacuum valve connecting to a vacuum or inert gases source.The top ground glass joint is used to attach the flask to other lab glassware apparatus ,or stopped by a penney head stopper,rubber septum,permitting easy transfer of liquids or solids.
- USE----Schlenk flasks are indispensable laboratory glassware used in air-sensitive chemistry to conduct air-sensitive reaction.Comparing to non-air-sensitive reactions reaction, this schlenk flask features a 0-9mm high vacuum valve connecting with a schlenk line and controlling the access to inert gas or vacuum. In a reaction setup,the schlenk flask may use with an addition funnel,reflux condenser,magnetic stirring shaft and bars.For filtration,a schlent frit is required.
- DIMENSIONS----This pear-shaped schlenk flask,modified schlenk tube, capacity of 100mL,with 0-4mm high vacuum valve which is easier to clean and won't leach grease into your reaction mixture.With 24/40 top taper outer joint allowing material to be added to a flask or attaching a reflux condenser for reaction.
- HEAVY WALL ---This schlenk flask is heavy-wall designed , made by hand-blowing according to ASTM E438 ,made of high-quality borosilicate glass and annealed at 812 degree Celsius ,can be heated directly in an open flame and can withstand typical laboratory thermal variations in Chemistry processes like heating and cooling,durable and reusable.

*by T***N on Reviewed in the United States on October 24, 2019*

I love Laboy. In my experience they are a hair under Chemglass in quality but a third as expensive. This piece is a shorter and fatter 500 mL Schlenk flask than the other ones I've seen. This makes handling it and fitting condensers and adapters above it easier but keeps all the Schlenk appeal. Highly recommend
