Series 4760-4777 General Purpose & High Temperature Pressure Vessels, 100-600 mL

Series 4760 Ordering Guide

This series is available in five volumes, each with a choice of head styles, four different alloys, and comes standard with a flat gasket, a split-ring closure with six cap screws. Add a Q to the model number for a vessel with an O-ring seal and split ring with no cap screws — note, this limits the maximum temperature to 225 °C. Or add an HT (to the HT-capable models) to achieve a higher maximum working temperature that uses a flat Grafoil gasket.
