Description
Test tube rack insert for 21 test tubes is a plastic laboratory insert designed for a maximum of 21 reagent tubes with 30 mm diameter. It can be used at temperatures of up to 100 °C and supports tempering work in laboratory baths and compatible temperature-control setups. The insert is supplied as 1 pc and has a net weight of 0,600 kg. From manufacturer Julabo, this accessory holds tubes securely and upright during heating or cooling of samples. For tempering of solvent-containing or acid-containing samples above 60 °C, stainless steel test tube inserts are recommended, as the plastic material can be attacked. Inside its permitted temperature window the plastic insert is a practical option for routine series that do not require the chemical resistance of metal. Twenty-one positions allow compact parallel processing while each tube remains easy to reach. The 30 mm diameter specification defines the tube format the insert is intended to accept. Originating from Germany, it forms part of general laboratory materials used with temperature control equipment for organised multi-tube workflows.
