your own cells.Increased production of mammalian cells and viruses is nowpossible by growing cell monolayers in roller bottles. Instead offlat bottles, the Rollacell utilizes cylindrical vessels that provideincreased growth area while reducing laboratory space andmedium requirements. Large numbers of tissue culture bottles canbe rotated simultaneously at any speed between 0.1 rpm and 8 rpm.Because of its modular design, a single bench scale unit canbe readily converted for production applica-tions by merely adding one or more roller tiersas the need arises. An incubated unit is alsoavailable with a built-in roller drive for precisecontrol of temperature as well as speed. TheRollacell is made in sizes up to 10 tiers.

Temple University, Department of Biology, willoffer two courses in Developmental Biology ofMarine Invertebrates at the Marine BiologicalLaboratory, Woods Hole, Mass., 6 May to 2June 1974. One course (four credits) will consistof an intensive lecture and laboratory survey ofthe development of all major and some minormarine invertebrate phyla from both descriptiveand experimental points of view. The secondcourse (four credits) will provide an opportunityfor guided research on a problem in invertebratedevelopment. The courses run simultaneously andthe research course requires a background in in-vertebrate development equivalent to the surveycourse. Space for 15 in the survey course, and5 in the research course. Tuition, $216 ($308 forout-of-state students) for each course; living costs,$52 per week.

ViW *A .*rtical illuminator forincident ight fluorescence

You can extend the versatility of your AO MICRO-STAR microscope with the simple addition of ournew compact Vertical Illuminator for incident lightfluorescence microscopy. It fits any Series 10 or 20microscope; attaches easily and quickly; requiresno alignment or adjustment.Fluorescence intensity is maximized by excitationwith UV incident light regardless of specimenthickness or density. The microscope objectiveserves as both condenser and objective. Full fieldcoverage is assured, even with the 1OX objective.

Exciter, barrier and dichroic filters are turretmounted for dial-in convenience. More than that,they can be identified by touch when working insubdued light.Convert to conventional transmitted light merelyby rotating filter turrets to a neutral position.See your AO dealer or representative or send fordetailed brochure on the AO Vertical Illuminator.If you don't have a MIICROSTAR microscope to useit with, we'll be glad to supplv information onthe Series 10 or 20 also.
