Here we play while the rest of the world sleeps, or so it seems. When I get up in the morning the second thing I do is read my email. First thing? This is when I get customers and potential customers asking questions. Questions about applications and problems. One of today's potential customers had [...]
Dual pump sets are for producing continuous fluid flow by using reciprocating pumps.
Syringe Pumps and Peristaltic Pumps are computer controlled mechanical machines. They get dusty - even in clean environments. These great laboratory devices cost a lot of money - so you should look after them by performing some pump maintenance for a long pump life time. Reliability and repeat-ability of pumping flows are important to manufacturing [...]
I fully support the clever people making open source syringe pumps. But I don't support some of their outrageous claims. Worse still nobody ever seems to challenge them. None of this page is intended to be an attack on any person or project - but some of these claims - WOW! If you wish to [...]
VIDEO: Loading A Syringe on Your Pump This short video shows you how to load a syringe onto your syringe pump. Please note that the video starts with the both Syringe Retainer Thumbscrews loosened and the Syringe Retainer Bracket separated from the syringe v block ready to accept the [...]
Programmable syringe pumps have a limited number of program steps. Basically they only have so much on board memory available. What are some techniques for growing past this limit? Sometimes your pump program grows and then grows and then grows and suddenly 41 steps becomes a limitation. This limitation is like colliding with a brick [...]
There comes a time in an old pump's life when it develops problems of low pressure. Is your syringe pump suffering from these symptoms? Low pressure - your pump doesn't deliver anything like the pressure the manufacturer claims Doesn't stop pumping when the syringe pusher block hits the end stop. Could be a stalling problem [...]
Syringe pumps are supposed to automatically stop when they had reach the end of the plunger travel. This is called stall detection. There is stall detection circuitry which can see the high load on the motor and signals the computer in the pump to stop applying the driving force. This is to protect the tooth [...]
drawing board Before you can start programming your pump, you need to understand the flow you require in detail. For a simple single rate and volume flow you hardly need to spend much time on this. But for wave form flows or flows involving interaction with the real world (triggers) you really need [...]
Had a report recently from a customer who said my software constantly crashed. My software shouldn't' crash - ever but there will be problems from time to time - I can't test everything. When I learn of crash behaviour - I test and try to duplicate and then resolve the problem. I asked the customer [...]
