For users who want to use accessories for magnetic stirrers with 145 mm plate in combination with a 135 mm model, this adapter plate is available so that no compromise is made. This plate does not replace the installation surface of the magnetic stirrer, but is placed on it. It is made of aluminum so as not to prevent heat transfer.

• Boss head made of anodized aluminum, used to fix retort clamps to stand rods for perfect vertical alignment.
• Suitable for stand rods with up to 13.1 mm maximum diameter.

• Standard laboratory clamp to hold glass devices on ground glass cone / socket for perfect vertical alignment.
• The four prongs - cork-lined on the inside and aluminum on the outside - can securely hold glass devices with a diameter from 2 to 85 mm firmly in place.

• The PTFE safety cover ensures even more safety for every application with a Heat-On Block for a 1 liter round bottom flask.
• Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.

• The PTFE safety cover ensures even more safety for every application with a Heat-On Block for a 500-ml round bottom flask.
• Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.

• The PTFE safety cover ensures even more safety for every application with a Heat-On Block for a 200 - 300 ml round bottom flask.
• Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.

• The PTFE safety cover ensures even more safety for every application with a Heat-On insert.
• Despite the reduced danger when using Heat-On Blocks compared with a conventional heating bath, the risk of burns is not zero. We therefore recommend using a safety cover made of chemical-resistant, easy-to-clean PTFE.
• This safety cover is only suitable for the Multi-Well holder that encloses the Heat-On inserts.

• The Heat-On safety lifting handles are like the handles on a hot pan: essential for your safety.
• Available as a pair, the safety lifting handles are easy to operate. Simply press the blue button to insert and remove the handles.
• The bottom element, which is placed in the Heat-On Block or the Multi-Well holder, is made of stainless steel.
