 Can the leads in the headstage DIN connector be repaired?
Yes. While we can make a repair at the factory, it is a simple enough task that the user can make a repair on-site.The connector used for most Warner devices (amplifiers, temperature controllers, etc.) are known as DIN type connectors. They can be opened by removing the set-screw on the side and ...
- How can I exceed the 10 ml/min flow-rate limit for inline solution heaters?
This can be achieved by using two in-line heaters (e.g., two SH-27B) and a dual channel temperature controller. Basically, split the incoming flow line into two just prior to the in-line heaters (one heater per line) and then rejoin the lines before delivery into the chamber.Another approach wou ...
- How can the temperature of the perfusate be monitored once it exits an inline solution heater?
Warner's inline solution heaters (SH-27B and SF-28) and inline solution heater/cooler (SC-20) is supplied with a separate thermistor cable assembly (TA-29) that allows for monitoring the temperature of any point of interest (usually the bath itself).
- How can the temperature within an inline solution heater or cooler be monitored?
Warner's inline solution heaters (e.g., SH-27B, SF-28) and inline solution heater/coolers (e.g., SC-20) contain a built-in feedback thermistor and so do not require a separate thermistor for setting and monitoring the control temperature.A temperature control unit (e.g., TC-324B, TC-344B, CL-10 ...
- How do I clear a clogged SF-28 or SH-27B inline solution heater?
There are several approaches to take, starting with the most gentle. First, fill the tubing with ethanol and let it soak for a while. If necessary, use some pressure to force ethanol through the tubing. If there is still a partial clog, try to get some dental floss through the tubing and gently ...
- Is it possible to use temperature feedback from the bath to regulate an inline solution heater?
Unfortunately, no. Feedback in inline solution heaters is derived from thermistors located within the heater body. This prevents oscillations in temperature which can arise when the temperature sensor is distal to the heat source..
- When is in-line heating preferred over chamber heating?
Generally speaking, heating a platform alone is a good strategy only for very slow or non-flow conditions. The solution loses most of its heat enroute to the chamber. Under the more common flow conditions of 2-10 ml/min, an inline heater is a better way to deliver heated solution to a chamber.Co ...
- Can an inline solution heater be cleaned in an ethanol steam sterilizer?
We dot recommend steam sterilization.During ethanol steam sterilization, the seal on the inline heater may not be tight enough to prevent fluid from reaching the electronics within the heater . Using ethanol, however, to flush the stainless steel tube within the heater body should be sufficient.
